Supported scope. Claude Code and Codex JSONL text/tool records only, not ChatGPT export ZIPs or arbitrary chat formats. Maximum 100,000 characters per visible message and 5,000 review candidates in this browser tool; use the Python CLI for larger reviews. Private terms: at most 1,000, each up to 4,096 characters. Unknown records, reasoning, images, absolute timestamps, and source filenames are omitted. Detection cannot find every secret. Close this tab or use Clear & reset to discard the open review; a downloaded export remains on your disk.
