Chronica 0.1.0

Chronica is a local work-context collector for macOS: it transcribes your microphone and your system audio continuously, on device, and optionally keeps a text journal of what you were working on. Nothing leaves your Mac — no account, no telemetry, no cloud.

What's in 0.1.0

• Two audio tracks at once — microphone and system output (the other side of a call, a video) — sliced into intervals on silence and transcribed by Parakeet TDT 0.6b v3 (25 languages incl. Russian) or Whisper.
• One journal — speech and screen activities in a single timeline, with dividers where recording started, stopped, failed, or the app was closed.
• Optional screen journal — a periodic still frame described by a local vision model through Ollama. Off by default; screenshots are never stored.
• Your data, back — full-text search, JSON/Markdown export for any period, a local HTTP API (/api/v1, off by default, loopback only) and a chronica CLI that reads the same database without the app running.
• Menu-bar app in English and Russian, following the system language.

Requirements

macOS 14.0+ (14.4+ for system audio without ScreenCaptureKit), Apple Silicon. The default model is ~640 MB and downloads on first run.

Installing this build

This release is signed ad-hoc and is not notarized — a Developer ID certificate is not in place yet, so Gatekeeper blocks the first launch. Drag the app to /Applications, then either:

xattr -dr com.apple.quarantine /Applications/Chronica.app

or open it once (it will fail) and press Open Anyway in System Settings → Privacy & Security. Signed, notarized releases will follow.

Verify the download against Chronica-0.1.0.dmg.sha256, or build it yourself: docs/BUILD.md.

Notes

The Android client in this repository is experimental: it builds from source, has not been verified on a device, and gets no releases. Model licences and third-party components are listed in THIRD_PARTY_NOTICES.md; the Parakeet model is © NVIDIA under CC-BY-4.0.
