Open source Focus intelligence

Stashyour day.

Acorn is a warm, open-source AI desktop companion. Type or speak everything bouncing around in your head, and it returns ordered task cards with priorities and estimates — surfaced one at a time, so they actually get finished.

The problem

The list that never gets done

A day's worth of loose thoughts rarely survives contact with a to-do app. Acorn takes the raw dump — typed or spoken — pings the model of your choice, and hands back ordered cards it walks you through one at a time. A local SQLite file holds the data; the OS keychain holds the keys; nothing leaves your machine that you didn't send yourself.

Capabilities

What Acorn does, precisely.

Dump, don't organise

One textarea or the microphone, one Stash it, and the AI does the sorting — priorities, estimates, and order — so the first move is never admin.

Model-agnostic by default

Anthropic, OpenAI, DeepSeek, OpenRouter, Ollama, and more. Bring a key, run a local model for free, or reuse an existing claude / codex / gemini CLI login as a provider.

Native, not Electron

Tauri 2 and React 19 — roughly ten times smaller than the Electron equivalent. It lives in the menu bar, summoned with ⌘⇧A and dismissed without quitting.

Your data, your machine

SQLite on disk, keys in the macOS Keychain, voice transcribed only when you ask. A warm autumn interface designed around an aesthetic, not a default theme.
