Features

Four sources, one list

JSONL for Claude Code / Codex / Cursor CLI, and raw protobuf-in-SQLite for Antigravity CLI, decoded without a .proto definition.

Identical on every platform

egui draws every pixel itself and a Japanese face is bundled, so macOS, Windows and Linux look the same.

Filter by agent and project

Projects merge across agents, so one entry shows everything every tool did in that repo.

Full-text search

Matches are highlighted in both the session list and the conversation.

Incremental rescan

Files are memoized by mtime + size, so only what changed is reread.

Read-only

It never writes to an agent history. The only outward action is opening a project folder in your file manager.

Install

Download the archive for your platform from Releases. No installer, no runtime: SQLite is compiled in and the font is embedded.

./chist-viewer              # open the window
./chist-viewer --dump       # headless summary of what was parsed
./chist-viewer --version

Support & limitations

macOS	Signed with a Developer ID certificate and notarised, with the ticket stapled — opens without a warning.
Windows	Not code signed, so SmartScreen warns on first run: More info → Run anyway.
Linux	install.sh places the binary in ~/.local/bin and registers the desktop entry and icons. No root needed.
Limitations	Older Cursor CLI transcripts have no timestamps (mtime shown, marked ~). Antigravity CLI is decoded without a .proto, so a format change could drop messages.
