I'm seeing way bigger productivity gains from building personal desktop apps than personal web apps. My personal super desktop app is insane. Saves me hours/wk.

Public example of the genre (not a dump of the private hours/wk tool): RileyJarvis, the Electron companion he open-sourced — github.com/rbrown101010/rileyjarvis (MIT).

One-sentence TL;DR

Stop shipping yourself little web dashboards. Build a local desktop app around your loop, let an agent keep extending it, and treat that as home base. For him, that personal desktop super-app is currently more useful than the personal web apps he used to make.

What he means (narrow claim)

This is not “desktop apps in general are better than the web.” It’s from how he actually works:

1. Personal apps, not products. He vibe-codes tools for his workflow. No product name, no users, no marketing. Just something that does exactly what he wants. He said that earlier about a desktop app he made for Excalidraw presentations, then added YouTube thumbnail generation in one shot.
2. Desktop beats web for that use case. A personal web app still lives in a browser tab: limited OS access, login/session friction, weaker file-system and window control. A personal desktop app can sit on the machine, read local files, drive other apps, take screenshots, click/type, and keep state locally.
3. “Super desktop app” = one shell for most work. He’s been arguing for months that the endgame is a single agent interface you start every task from, instead of bouncing between browser, email, Notion, etc. He called that a “super-app.” This tweet is him saying the version that actually saves him hours is the desktop one, not a personal web OS.

That’s why people in the replies asked for a walkthrough. He claimed a private tool is saving hours a week and didn’t show it in that post.

Why desktop, in his world

Riley’s whole beat is “agent-native” work: coding agents, Codex / ChatGPT desktop, computer-use, remote control of a Mac. Desktop is where those agents can actually touch the computer.

He’s also said that once you put a full browser inside a desktop agent app, separate web tools start to look unnecessary — the agent opens the site in its own browser and works there.

RileyJarvis — the public Electron example

RileyJarvis is a local Electron desktop AI companion: realtime voice, a visual artifact panel, image generation, web search, notes, and opt-in macOS computer control. Stack: Electron, React, Vite, TypeScript, OpenAI Realtime API.

Repo: github.com/rbrown101010/rileyjarvis . README clone URL still says github.com/rileybrown/rileyjarvis — that path 404s; use rbrown101010. MIT. macOS only.

That’s the genre: a local AI desktop that is yours, not a SaaS tab. It is not a screenshot of the private “hours/wk” super app. Don’t treat the open-source companion as the whole claim.

What it actually ships

• Realtime speech-to-speech with OpenAI Realtime
• Animated companion face (listening / thinking / speaking / working)
• Artifact panel: markdown, menus, notes, Mermaid, generated images, records, progress
• YouTube thumbnail board with persistent numbered generations and image edits
• Optional Exa-powered web search
• Local notes and records under runtime data/ (gitignored)
• Optional computer-use mode: open apps, click, type, scroll, screenshots, UI inspection on macOS — blocked until that mode is on

Clone and run

git clone https://github.com/rbrown101010/rileyjarvis.git
cd rileyjarvis
npm install
cp .env.example .env.local
# OPENAI_API_KEY=...   (required — Realtime + image gen)
# EXA_API_KEY=...      (optional — search)
npm run dev

Needs Node 20+, an OpenAI key with Realtime + image generation, and (if you turn on computer-use) macOS Accessibility + Screen Recording plus the microphone for voice. Dev mode starts Vite on 127.0.0.1:5173 and launches Electron.

Security notes from the README (keep these)

• Keys load only from local env files. Don’t commit .env.local or data/.
• Risky computer-control actions should require explicit confirmation.
• Typing and pressing Enter in computer-use mode are intentionally allowed without extra confirmation — they’re core voice-control actions. That’s the gym-hack class of permission. Fence send / delete / spend elsewhere.

Not the ChatGPT + Codex “super app”

On this site, “super app” already means two different things. Don’t mash them:

The OpenAI desktop is a product you log into. The personal super desktop app is a repo you own. He can add a thumbnail board in one shot because there is no product manager. That’s the whole point.

How this maps here

Week-one sitting (steal the pattern, not his UI)

1. Pick one loop you already do every week (thumbnails, Excalidraw decks, inbox triage). Not a “personal OS.”
2. Clone RileyJarvis or start a blank Electron/Tauri window. Keep state in a local folder.
3. Add the one feature that currently lives in a browser tab. Stop.
4. If you turn on computer-use: Accessibility + Screen Recording, then a deny list (send / delete / spend / publish) before you let it type Enter. Same fence as Auto-review.
5. Let the agent extend the app next sitting. That’s the compounding he’s talking about — not a public launch.

What we keep vs skip

• Keep: personal ≠ product; desktop for OS access; one shell as home base; local data/; RileyJarvis as a cloneable genre; fence computer-use.
• Verify: whether his private hours/wk app is a heavily forked RileyJarvis or a different Electron; whether “full browser inside the agent” is in the public repo or only in the private one.
• Skip: “desktop is back, kill the web”; shipping RileyJarvis as a SaaS; treating this tweet as a walkthrough (it isn’t); mixing this with OpenAI’s ChatGPT+Codex super app.
