FunButton.ai

Talk fast. Stay local. Pay less.

The fun, dev-grade voice dictation tool. Press the button, talk, watch your cleaned-up text land at the cursor. No cloud lock-in. No 800 MB Electron tax. Zero API key, zero install — cleanup runs on a bundled local model out of the box.

Status: Sprint 1 building (May 8-11, 2026). MVP target: Monday morning.

What's different

	Wispr Flow	FunButton
Bundle	800 MB Electron, 8% CPU idle	~1 GB Tauri 2 (incl. bundled LLM), ~150 MB RAM cleanup-only
Cloud	required	optional (bundled local model is the default)
Code mode	not really	first-class — spoken symbols + casing taxonomy
API key	required	not required — cleanup runs on bundled Qwen 2.5 1.5B
Linux	none	first-class (post-MVP)
Source	closed	GPLv3 desktop core
Price	$144/yr, no lifetime	$99 lifetime founder pricing (planned)

Architecture

• Tauri 2 shell — single Rust binary + WebKit webview, ~10 MB.
• cpal for audio capture (Core Audio on macOS, WASAPI on Windows, ALSA on Linux).
• rdev for global Right Option push-to-talk (modifier-only key, requires Accessibility permission).
• Groq Whisper Large v3 Turbo (~300 ms TTFT) for transcription.
• Cleanup is pluggable:
  • Embedded (default) — bundled llama.cpp server + Qwen 2.5 1.5B Instruct Q4_K_M GGUF, spawned as a child process on app launch. Zero install, zero key, runs offline.
  • Groq Llama 3.3 70B — fastest, cloud, requires GROQ_API_KEY or a FunButton license.
  • Ollama at localhost:11434 — external Ollama if you've already got it (power-user path).
  • Auto — tries embedded → ollama-external → groq, picks the first that's available.
• Code mode — auto-detected from the frontmost app (Cursor / VS Code / JetBrains / Vim / Terminal / Xcode). System prompt handles spoken symbols (open paren → (, arrow → ->, equals → =) and casing (camelCase X Y Z → xYZ, snake_case X Y Z → x_y_z, etc.).
• Text injection — clipboard write + Cmd+V via enigo, with prior clipboard restored ~1 s later.

Install

(Pre-release — until v0.1.0 .dmg exists, build from source.)

git clone https://github.com/todddickerson/funbutton.git
cd funbutton/apps/desktop/src-tauri
bash scripts/fetch-vendor-deps.sh   # one-time: pulls llama-server + Qwen 2.5 1.5B GGUF (~1 GB)
cd ..
npm install
npm run tauri build -- --target aarch64-apple-darwin
open src-tauri/target/aarch64-apple-darwin/release/bundle/macos/FunButton.app

If macOS Gatekeeper blocks the unsigned build: sudo xattr -cr /Applications/FunButton.app.

First run: macOS will ask for Microphone and Accessibility permissions. Grant both. The bundled LLM warms up in the background and you'll see a toast when it's ready (~1 s warm cache, ~10 s cold).

Note on transcription: Whisper transcription is not bundled yet. Free-tier users still need a Groq key OR a FunButton license for the speech-to-text step. The cleanup model is fully local. Bundled Whisper is on the V1.2 roadmap.

Install with a coding agent

Live in Claude Code, OpenClaw, Cursor, Codex, or Hermes? Hand the install to your agent. Paste the prompt in AGENT-INSTALL.md and it will install FunButton (brew cask first, curl one-liner, then manual .dmg), verify the app launches, surface the ~1.1 GB first-run model download, and hand the three macOS permission grants (Microphone, Accessibility, Input Monitoring) back to you — no agent can grant those.

Agents should fetch the machine-readable contract instead of scraping the site:

• Install contract: https://funbutton.ai/install.json (versioned schema: latest version, DMG url + SHA-256, install methods, required permissions, model size, a verify block)
• Discovery: https://funbutton.ai/llms.txt

Use

1. Hold Right Option.
2. Talk.
3. Release.
4. Cleaned text appears at your cursor.

Tray menu: Settings opens the configuration window. Quit exits the app.

Develop

cd apps/desktop
npm install
GROQ_API_KEY=... npm run tauri dev

Verify the pipeline without installing

You can sanity-check that the Groq Whisper + Llama cleanup chain works on your network and key, without installing the .app:

brew install jq ffmpeg  # one time
GROQ_API_KEY=gsk_... ./scripts/test_pipeline.sh

It synthesizes a WAV via macOS say, runs the full pipeline, and prints raw vs cleaned. Pass your own phrase as the first arg.

License

GPL-3.0-or-later (desktop core). Cloud / sync / team features (when they exist) will be source-available under a separate license.
