Contextify for Windows – Live Index of Your Claude Code/Codex History

Hello, I'm Rob and I've been working on Contextify since October of last year. Besides creating Back to the Future time machines for the docs page [1], I've been working on adding a Windows client since mid-July.

Contextify indexes your entire local Claude Code and Codex sessions into a local SQLite/FTS index as they happen. This lets you aim your agents at your real-time and complete historical AI-coding (or other project type) history.

It works purely locally but has an option for hosted or self-hosted cloud sync to read it on another machine, along with a hosted option if you want turn-key.

HN and some existing users requested a Windows client. In some cases it is because their self-hosted setups include Mac, Linux and Windows boxes that are all generating CLI AI transcripts (sometimes headlessly)

This product started as a macOS app; 1.8.0 brings it to Windows (x64 and ARM64) and extends the Linux CLI. It is free for personal use and has a source-available self-hosted option. I have commercial licenses available, and a few very much appreciated customers so far.

On Windows it's a background agent plus a CLI, with no history-browsing UI yet.

Lots of interesting development was needed to pull this off (including a shared Swift core!) in a way where it could be updated as easily as prior to the release. I'll share some of that in a comment below.

If you use Windows and would be open to giving this a go, I'd appreciate any feedback here or via rob@contextify.sh.
