shyn — your Mac’s memory, on tap ☀️

Shyn is the always-on memory companion for your Mac. It quietly remembers what you see, hear, and read — your screen, your meetings, your browsing, your notes — and gives your AI assistant total recall over your life. Ask Claude “what did we decide in yesterday’s standup?” or “where did I read about that retention bug?” and get an answer grounded in your own history, not the internet’s.

Your memory stays local. Private by design. Everything shyn captures lives in an encrypted database on your Mac. Nothing it captures is uploaded, synced, or phoned home — the only bytes that ever leave your machine are the few snippets relevant to a question you chose to ask, sent to the AI you chose to ask it.

During beta, shyn also sends anonymous usage data. shyn runs across different macOS versions, hardware, and permission states, and those combinations produce bugs we cannot reproduce or test for. Most people who hit one never write in; they just quit the app. So shyn reports which features get used, what crashes, its version, and timing numbers, tied to a random ID that is not you.

It never includes anything shyn captured. No screen text, no transcripts, no searches, no identity. You choose on first run, and one click in Settings changes it any time. Turn it off and shyn is exactly what it promises above: nothing but your own questions leaving your machine.

Status: pre-alpha. Shyn is young, moving fast, and macOS-only (Apple Silicon). Expect rough edges and breaking changes. Install is a two-command Homebrew cask (brew install + shyn setup) — the apps are self-signed and re-signed locally by shyn setup, not Apple-notarized; notarized one-click installs are on the roadmap.

Why shyn

• 🧠 Total recall, instantly. Hybrid search — keyword (FTS5/BM25) + semantic (on-device embeddings) — across everything you’ve captured, in milliseconds, over a local socket.
• 👁️ Ambient screen memory. A featherweight agent captures the text on your screen as you work — what you read, wrote, and clicked becomes searchable history.
• 🎙️ Meetings, remembered. Shyn detects your calls, records both sides locally, transcribes on-device with Whisper, and files a speaker-labeled transcript into your memory. Audio never crosses a socket and is purged the moment the transcript lands — text in, bytes gone. Grant Calendar access and transcripts get titled from the event they belong to (“Sprint standup”, attendees included) — read from your Mac’s own calendar store, no Google API, nothing leaves the machine.
