Think it.
Drop it.
AI plans it.
Press ⌘⇧D from anywhere on your Mac. Speak a thought, type a note, or paste a screenshot. Captio figures out if it's a task, event, or idea, and schedules it straight into Apple Calendar. Everything stays on your Mac, private by default.

Local-first AI
Gemma 4 + vision projector run on your Mac
Cloud-only or no AI at all
Questions answered.
Free right now. Pricing is undecided for the future; early users will get a heads-up well in advance before anything changes.
Locally, in a SQLite file under ~/Library/Application Support/com.captio.app/. If you switch to a cloud AI provider, capture text and screenshots are sent to that provider only when classification runs. Captio itself has no server-side database.
Only for cloud mode. Local mode runs Gemma 4 entirely on your Mac. If you do use a cloud key (Claude, Gemini, or OpenAI), it is stored in macOS Keychain. Captio never sees the plaintext after you save it.
macOS 13 (Ventura) and newer, on Apple Silicon or Intel. The local Gemma path is much faster on Apple Silicon (~1–2 s) but works on Intel too.
macOS first. The codebase is cross-platform Tauri so Windows and iOS are technically possible; they are roadmap items based on demand.
Local mode uses a 987 MB BF16 vision projector (mmproj) loaded alongside Gemma 4. Toggle "Screenshot reading" in Settings → AI to download it. Cloud mode uses the chosen provider's native vision API.
Yes. The mic icon only does anything if you click it. The Whisper sidecar runs locally; if you never use voice, it never starts.
Drag Captio.app to the Trash. To also delete data: rm -rf ~/Library/Application\ Support/com.captio.app/. To remove the Gatekeeper attribute: xattr -cr /Applications/Captio.app before deleting.
Run Captio on your Mac.
Apple Silicon and Intel builds in the latest GitHub Release. The first install needs a one-click Gatekeeper bypass; the install guide walks you through it.
