Codex used a Safari extension I wrote to recover a ChatGPT conversation for a coding project: 1,651 message records and 97 artifacts. It knew about LogGPT from memory; I hadn't told it to use it. Then it verified the files. That was quite a morning.

extract-chat v0.7.8 keeps more of the original conversation intact: authored Sources and References sections survive rendering, mixed timestamp formats no longer derail dated output, and older LogGPT ZIP artifacts keep working local links.
LogGPT Plus can preserve a conversation and its artifacts. Version 1.2.1 gives you status - documents counts and watch progress for Plus Users. Update available now or get it at the App Store.
Your chat is yours, no tracking, collection and total privacy.
