     13 This is an update to my post [9]about apps as home-cooked meals, which has
     14 found a large audience over the years. That post, published in February 2020,
     15 discussed personal software, designed and built in different ways, for
     16 different reasons, than industrial apps.
     17 
     18 What’s changed between 2020 and today? Oh, just the entire process and practice
     19 of computer programming. Here, right up front, I decree: building a personal
     20 app with the help of AI agents still totally counts as “home cooking”. You’re
     21 no longer grinding the flour by hand; fine. This is a cool development. You do
     22 still have to make the meal taste good, and this still requires care and
     23 effort. Fine.
     24 
     25 The AI industry’s immediate future has more to do with exotic finance and
     26 gnarly politics than the underlying technology. I’m not invested in that
     27 future; most days, I think a minor bust would be a good thing. But, that
     28 underlying technology, in its development and flourishing this past year — yes,
     29 really that recently — is profound. It reframes computing entirely, replaces a
     30 stack of API reference docs with this simple invitation:
     31 
     32 Ask for what you want.
     33 
     34 ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
     35 
     36 It began during one of my drives between the San Joaquin Valley and the San
     37 Francisco Bay Area, always an opportunity for daydreaming, generator of many
     38 voice notes. On this drive, back at the start of summer, I was doing some
     39 meta-daydreaming, pondering how my notes app worked, and didn’t, and I thought:
     40 “Robin, just tell the AI agent to make the app you want.”
     41 
     42 I got home, and I told it, and I cooked dinner, and by the time I went to bed,
     43 I had my new notes app, native macOS. I began using it immediately, and over
     44 the next couple of weeks I refined it, explaining my preferences to the AI
     45 agent. The app has taken pole position on my dock, and I use it every day.
     46 
     47 I’ll explain my process in more detail, but first, I’d like to propose an
     48 exploratory program. This is recommended for anybody/everybody, but more
     49 pointedly for creative people who are wary about AI. I’m wary, too — cautious
     50 and critical — yet I believe my experience this summer educates and enlivens my
     51 criticism, rather than undermines it.
     52 
     53 And … even if you were an enemy of the railroad corporations, the vast
     54 syndicates … would you deny yourself the pleasure of the train?
     55 
     56 This exploratory program only works with the summer 2026 generation of models:
     57 
     58  1. Download the desktop app for either Claude or ChatGPT.
     59 
     60  2. Pay for the monthly plan that gets you access to the top-tier model, either
     61     Fable 5.1 or GPT-6 Astra — just one month.
     62 
     63  3. This is a trial, a test, an education. Well worth it.
     64 
     65 Why even publish this post, when the internet is awash with AI boosterism,
     66 AI-can-change-your-life-ism, tell your Claude to do this, teach your ChatGPT to
     67 do that? Because I think my approach is better, obviously. The consensus vision
     68 seems to involve AI working for you day-to-day, a constant ambient presence,
     69 sparkles in everything; even cautious Apple has succumbed. I’m not interested
     70 in that.
     71 
     72 My alternative: get your wish, then stuff the genie back into the lamp.
     73 
     74 ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
     75 
     76 As you begin your exploration — this sounds sort of random, but — I strongly
     77 suggest that you ask your AI agent to build a native desktop app, rather than a
     78 web app. Seeing a new icon in your dock drives home the understanding: this
     79 environment is malleable. It can, at last, be anything I want.
     80 
     81 So … what DO you want? For me, this was straightforward. I have always used a
     82 rotating collection of apps for writing, note-taking, managing images, and
     83 more, so it was an easy call to say, “those, but simpler and faster”.
     84 
     85 Alternatively, you might think about computer tasks that are currently annoying
     86 or overwhelming. As the capstone for my AI summer, I built myself an email
     87 client! It’s very simple, just a particular view of my professional Gmail
     88 account, filtering and presenting a subset of messages, sparing me the full
     89 kinetic impact of my inbox. It’s called Grand Vizier. It’s great.
     90 
     91 That’s all very “productivity”. It would be just as good, even better probably,
     92 to ask for something fun. A game! Or, how about, I don’t know, a jukebox to
     93 play music from a streaming service, without all that extra junk they cram in
     94 there. Doesn’t matter which service you use — the AI agent will figure out how
     95 to wire it up, tell you the steps, ask for what it needs.
     96 
     97 There’s a crucial limitation here, which is that your need or desire must live
     98 “inside the box”, within the realm of apps and files, pixels on screens. Most
     99 of life doesn’t happen in here. If, indeed, none of your needs or desires are
    100 app-shaped … well, that’s not unusual! I have chatted about this with several
    101 friends who pondered a while, then declared: “I don’t have any problems that
    102 software can solve.”
    103 
    104 If that’s you, close this tab and proceed with your day.
    105 
    106 ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
    107 
    108 When I arrived home after my daydreaming drive, I sat down at my laptop
    109 and … did NOT open an AI agent. Instead, I spent an hour writing a document
    110 explaining what I wanted. I pulled in references to [10]an old app I used to
    111 love. I wrote at length about what I didn’t want my app to do.
    112 
    113 There’s an appealing looseness that is available, writing this kind of document
    114 for an AI agent. You should imagine the agent “reading everything at once”—all
    115 the words understood in parallel, their relationships and cross-dependencies
    116 and even inconsistencies simultaneously available. Rather than “a clear,
    117 sensible explanation”, you are aiming for “useful guidance on the page”. More
    118 is usually better.
    119 
    120 Here’s the exact doc I wrote on that night, which I titled VISION.md. I offer
    121 this not as any sort of “best practice” but simply as an example of how you can
    122 approach these.
    123 
    124 VISION.md
    125 
    126 We are going to built a lightweight, super minimal, VERY VERY fast notetaking
    127 and reviewing tool for macOS! Super fun!
    128 
    129 We’ll write this in modern Swift, keeping it as simple as possible. Really lean
    130 system. It targets macOS Sonoma and above.
    131 
    132 There are a few inspirations to know about.
    133 
    134 One is the classic macOS program Notational Velocity. You can do some web
    135 searches to learn about this app. There’s a screenshot in nv-main-window.png.
    136 
    137 We want to reflect NV’s obsession with speed. Now – our demands aren’t
    138 infinite. This isn’t like a live scrollable database of millions of notes. In
    139 fact it probably doesn’t even have the same demands as, e.g., the Apple Notes
    140 app, or the Photos app on iPhone. We are looking to support in the range of
    141 ~20,000 notes. So it’s very possible we can just like … load all of these into
    142 memory! Right?
    143 
    144 The source of the notes will be a selectable local directory. Sync will happen
    145 via another engine – Dropbox, in most cases. The point is, all we have to do is
    146 worry about local files. We DO want to detect when they change / are updated /
    147 added / removed, etc., but I suspect we get this “for free” simply by following
    148 macOS best practices.
    149 
    150 Setting this sync directory should be the app’s one main setting. It should
    151 have a settings/prefs window, just like an macOS app, reachable by a menu item,
    152 and the usual keyboard shortcut. We’ll start with just this one single setting.
    153 
    154 Another inspiration is the app Bebop, by Jack Cheng – https://jackcheng.com/
    155 bebop/ – which is where most of our notes come from, in practice. Bebop is the
    156 mobile “writer” app and this app we’re building is the “reader” app.
    157 
    158 Oh, I forgot to mention, this app will be called Rocksteady.
    159 
    160 The notes will be Markdown files, sometimes plain text – the app should handle
    161 both easily. Rendering Markdown correctly is NOT a goal for a first version –
    162 we should just display the plain text.
    163 
    164 We’ll want to implement NV’s very very fast search, which does a “live filter”
    165 – so, in the search field, as I type “bat”, it insta-filters all the notes,
    166 showing me only notes with “bat”; then, as I continue typing, to write “batm”,
    167 it shows me only notes with “batm” … and so on. (This will be all my “batman”
    168 notes, of course.)
    169 
    170 I don’t think fancy search tech will be needed for this – again, the quantity
    171 of notes is such that a relatively simple search algo operating on text in
    172 memory should be sufficient. However, if you disagree with this assessment,
    173 please let me know!
    174 
    175 The design should be “classic macOS”, using entirely default controls/buttons/
    176 widgets/etc. – nothing custom at all. We are making a really “Mac-assed” app
    177 here … in a sense we wish it was a classic macOS app, back in the days of
    178 System 7 … but we’re stuck with modern macOS, so, we’ll make the best of it.
    179 
    180 The app only allows you to look at one note at a time, the one currently
    181 selected. No tabs, no sub-windows, etc. – it’s very simple that way.
    182 
    183 The app should also allow me to edit notes, of course. I’m sure this can be
    184 accomplished with some default macOS text editor pane/widget. The behavior
    185 should be, when I start editing, a note is marked “dirty”, then I have to hit
    186 “save” (menu command, or command-S) to save my changes. Or, if I attempt to
    187 navigate away from it, the app should warn me with a dialog, “Abandon changes”?
    188 – again, super simple, super classic behavior.
    189 
    190 The app should support basic undo – I assume we get this for free from macOS?
    191 I hope so??
    192 
    193 No support for inline media, images, etc. – this is strictly text notes.
    194 HOWEVER if there are images in the synced folder – or indeed any other kind of
    195 file – the app should handle them gracefully. I think the best behavior would
    196 be to show them in the “notes list” as entries but make them grayed out,
    197 unclickable. Maybe we’ll add a feature later where clicking them opens them in
    198 the default handler app … maybe!
    199 
    200 The app’s layout should mimic a classic “note titles on left, note body on
    201 right” layout – most notes app do this. You can see a screenshot example in
    202 app-layout.png. The search bar should be on the top of the left column.
    203 
    204 Obviously, all the variables that dictate the layout (default width of note
    205 list, font sizes, etc.) should be vars in the code – so we can potentially wire
    206 them up to prefs/settings later. But we can start simple to make sure things
    207 are working.
    208 
    209 As a first step, I’d like you to produce a PLAN.md outlining an implementation
    210 approach.
    211 
    212 Ask me any questions that might be helpful, then proceed. Let’s build
    213 Rocksteady!
    214 
    215 (Please excuse my relentlessly chipper tone. I do believe it produces better
    216 results. What a weird technology.)
    217 
    218 This level of description isn’t strictly necessary; in fact, a sensible
    219 alternative is to cut straight to my last line: “Ask me questions.” The AI
    220 agents have all been trained to do this, and they’ll happily extract the
    221 information they need. That said, I think this writing exercise is valuable, if
    222 only to prepare yourself as a creative partner. If you’re going to ask for what
    223 you want … you need to know what you want.
    224 
    225 Okay, so, you write the doc, and you ask the AI agent to read it and produce a
    226 plan, and you look at that plan, and you say, make it so! The AI agent goes off
    227 and does its thing, working quietly for between ten and forty minutes.
    228 
    229 That’s what I did, and before I went to bed, I had my notes app. It was,
    230 honestly, dizzying to see the new icon waiting there in my dock. It was exactly
    231 what I wanted.
    232 
    233 Over the next couple of months, I refined the app, but only a little. It was,
    234 and is, basically finished. I suppose it helps that I had all my old notes to
    235 decorate this new space, making it instantly useful. Another point for plain
    236 text files.
    237 
    238 ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
    239 
    240 That success emboldened me to build an iOS sidecar, a capture-only notes app
    241 that is truly, gloriously, [11]a Homer Car.
    242 
    243 [sloan-home]
    244 
    245 This approach to software complicates traditional notions of “good design”,
    246 which are premised on the designer and the user being different people. When
    247 you are both, anything/everything becomes sensible, because the underlying
    248 logic is always totally clear to you! It’s sort of weird and amazing … a
    249 different experience of software. No mysteries.
    250 
    251 Implicit in this view is a sense of “continuous co-building”, which is how
    252 I approached these apps. Each began as something absurdly simple, barely
    253 anything at all, that I began to use immediately. As I felt myself reaching for
    254 missing capabilities, I kept a list. Over coffee, I’d ask the AI agent to
    255 implement them.
    256 
    257 This process wasn’t particularly fast, maybe not even particularly efficient,
    258 even with the AI agent cranking out code at warp seven. I took screenshots and
    259 pasted them into the chat and said “this looks weird”. I asked for new
    260 features, tried them once, said, “no, I was wrong, rip that out”.
    261 
    262 Working this way, you must become unembarrassed about nitpicking. You must
    263 become Steve Jobs, pointing out every misalignment, every detail insufficiently
    264 considered. You can be nicer than Steve Jobs, though.
    265 
    266 Understand: if you embark on this exploratory program, it will become your
    267 hobby for the next few weeks. It will be the thing you do in the quiet of the
    268 morning, over coffee, or in the quiet of the evening, before bed. If you are
    269 superbusy, if you have no quiet, this is probably not for you. That’s fine.
    270 
    271 [12]I know how to make apps on my own, yet the feeling of working on software
    272 in this way is totally different. Before, the prospect of any modification or
    273 expansion carried an underlying “oof”, the knowledge of the slog to come. Now,
    274 there is only a light and inviting “what if?”
    275 
    276 And, no: I don’t look at the code.
    277 
    278 ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
    279 
    280 For me, the aim is always a finished, standalone program — NOT a process still
    281 dependent upon AI agents. The prospect of a permanent tether makes me feel
    282 itchy. A distant API could fail, and you’d be … unable to do … anything?? Or,
    283 the distant API could suddenly cost more. Or, the quality of its responses
    284 could change. Sorry, but that’s the kind of unreliable computing I am trying to
    285 escape.
    286 
    287 I’d rather work with an AI agent to construct steady, sensible tools that will
    288 continue to work, no matter what. Call this Battlestar Galactica engineering:
    289 you must at least IMAGINE the Cylon uprising, and ensure that your spaceship
    290 will still function if or when that day arrives.
    291 
    292 “Your spaceship”, in this analogy, isn’t only your software, but your mind.
    293 Making these apps, I felt my programming muscles wither in realtime, the
    294 timelapse of the rotting apple. The idea of writing code by hand now
    295 feels … not impossible, but just SO excruciating. That feeling honestly
    296 frightens me, and I intend to keep it firewalled into this domain.
    297 
    298 ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
    299 
    300 One of the things I’ve come to enjoy is asking the AI agent to grind out
    301 performance improvements: “How can we make this snappier? How can we make it
    302 load faster? What’s the slowest thing about this app, and how can we fix it?”
    303 
    304 I suppose this is another reason I recommend starting with a native desktop
    305 app, rather than a web app — it’s easier to make something that absolutely
    306 flies beneath your fingertips. In an era of big, slow, cruddy software, it is
    307 refreshing, even electrifying, to use tools that are lightweight and superfast.
    308 
    309 You can ask for other things, too: “Review this code and make sure it’s simple,
    310 sturdy, and maintainable. If things have gotten too complex or wonky, find a
    311 way to rein them in, so everything feels really tight and solid.”
    312 
    313 The AI agents will happily do this again and again, as many times as you want.
    314 
    315 Discussing these AI systems, everybody wants to talk about “intelligence”, but
    316 I don’t think that’s the profoundest thing about them. Rather, I believe it’s
    317 the other -ences: patience, diligence.
    318 
    319 That latter one is important for me. I think of all the creative programs I’ve
    320 written, little scripts to render cool images, or maps, or whatever … always
    321 with a trail of shrapnel behind me — old versions, forgotten configurations. A
    322 sense of tumbling forward.
    323 
    324 Well, the AI agent really, REALLY wants to record the configurations. It will
    325 spin up a little web page admin screen to track all the different permutations
    326 and trials. It will do that in two minutes. This basic diligence and
    327 organization has been as transformative for my work as anything else.
    328 
    329 ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
    330 
    331 Okay, so. With the help of the AI agent, you make your first app. It bounces
    332 merrily in the dock. I want to underscore, what’s important is not that it’s a
    333 notes app, or a sleek jukebox, or whatever. You can already get every kind of
    334 app. What’s important is that it’s yours. It’s weird and specific, and it won’t
    335 change unless you want it to change.
    336 
    337 I propose a new and ongoing habit, asking this question: Is the computer
    338 working the way I think it ought to work? No? Okay, I’ll ask the AI agent to
    339 help me change it.
    340 
    341 This even applies to the agent itself, which is, of course, just software. Do
    342 you wish you could interact with it differently? Do you wish it would present
    343 its findings to you some other way? Just ask.
    344 
    345 There it is, the radical offering of 21st century computing, here at last: ask
    346 for what you want. It takes practice! And, honestly, a certain audacity.
    347 
    348 ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
    349 
    350 The moment of asking for an app and getting it is dangerous, because you feel
    351 like you accomplished something. You didn’t — not really. You can briefly enjoy
    352 that feeling, but I believe you must quickly discard it. The risk is that it
    353 pulls you into a loop, endlessly tinkering, refining, improving … and never
    354 emerging from your cozy AI workshop.
    355 
    356 You do, at some point, have to use your tools. You do have to actually make
    357 something.
    358 
    359 Rules for personal software produced with the help of AI agents:
    360 
    361  1. You must actually and consistently use anything you build for two months
    362     before posting about it.
    363 
    364  2. Ideally, never post about it. (I know I am breaking this rule, but my
    365     purpose is pedagogical, and anyway, I’ve got more apps I didn’t tell you
    366     about.)
    367 
    368  3. Don’t let the AI agent name the app. You pick the name.
    369 
    370  4. Don’t distribute the app, not even for free. Don’t post the code on GitHub.
    371     This is not software for glory; it is software for you.
    372 
    373 ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
    374 
    375 The [13]Culture novels of Iain M. Banks imagine a distant future that’s both
    376 dystopia and utopia. Dys- because the management of spacefaring civilization
    377 has been given over almost entirely to vast machine Minds, and u- because,
    378 well, you can ask them for whatever you want.
    379 
    380 It’s fun and provocative to read Banks as a dream of how far the genie can go.
    381 In his books, the Minds have mastery over not just information but matter, so
    382 characters are always like, asking for asteroids to sculpt … requisitioning
    383 small stars.

    385 Likewise, Star Trek’s depiction of the ship’s computer, particularly in The
    386 Next Generation, has suddenly snapped into prescience. This bravura scene, in
    387 which Geordi solves a mystery using the computer, is the best dramatization
    388 I’ve ever seen of this new way of working, better than Iron Man’s Jarvis by
    389 far:
    390 
    391 Put the Holodeck to one side; Geordi could easily be working at a screen. Watch
    392 him ask for what he wants — an iterative loop, a co-investigation.

    394 I think you should try my exploratory program because you’ll get something
    395 useful and/or fun out of it, and also because it is possibly the only way to
    396 understand the state of this techology today. Reading articles and posts
    397 (including this one) won’t get you there. And, some of the news is good!
    398 Working with an AI agent of the summer 2026 generation, you will realize its
    399 capabilites are prodigious, yet tightly circumscribed. It lives inside the box.
    400 
    401 Yet … I’ll confess, working with the AI agents more closely has also stirred in
    402 me a fear that’s not just intellectual but visceral — animal. Watching an agent
    403 encounter a bug, then grind through it, hypercompetent, confident,
    404 implacable … I think of Alien, the original movie, not the xenomorph, but its
    405 blood. Acid that eats through everything. The context for the agent’s
    406 relentless effort can be totally innocent — it can be a notes app — yet the
    407 behavior is still sincerely unsettling. It’s educational to watch up close.
    408 
    409 I’ve spent years engaged by AI, yet between this time last year and today, it
    410 become something totally new — a phase change — and I hadn’t truly caught up
    411 until now. I’m glad I did, and I encourage you to catch up, too.
