I built an open source version of OpenAI Chronicle.Some design decisions I made:1. Local first: OCR uses Apple Vision, summarization supports local AI providers via Vercel AI SDK. Nothing leaves your computer.
2. Multiple Provider: exposes MCP so any coding agents can use it.
3. Swift menubar app: efficient, low-footprint
4. Blacklist apps: password managers, messaging apps (Slack, WhatsApp, Messenger), mail clients are on default blocklist.Current Limitations:
1. Mac only. Mac-first is a feature.
2. Small local models with weak structured-output support will fail on generateObject.
3. Retrieval is LIKE-query keyword search. FTS and optional embeddings are on the list.Demo video (6s): https://youtu.be/V75tnvIdovcCurious what you think the right balance between exclusionlist allowlists. Happy to answer anything.
