Open Chronicle – Local Screen Memory for Claude Code and Codex CLI

Technical Positioning

An open-source, local-first screen memory tool for coding agents, using Apple Vision for OCR and supporting local AI providers for summarization. Designed as a Swift menubar app with a default blacklist for sensitive applications.

SaaS Insight & Market Implications

Open Chronicle addresses the critical need for persistent, private context for AI coding agents by providing local screen memory. Its "local first" design, leveraging Apple Vision for OCR and supporting local AI providers for summarization, ensures data privacy and security, a key concern for developers. The integration with MCP allows broad compatibility with various coding agents. By blacklisting sensitive applications, it mitigates privacy risks. This tool enhances agent effectiveness by providing a rich, on-device historical context, improving code generation and problem-solving capabilities while adhering to strict data governance principles.

Show HN: Open Chronicle – Local Screen Memory for Claude Code and Codex CLI

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):

what you think the right balance between exclusionlist allowlists. Happy to answer anything.
