Brain

Brain’s browser arm: preserve ChatGPT history baselines and automatically sync post-baseline browser deltas with provenance.

Brain is a private browser bridge between ChatGPT and your Brain account. Use it to preserve the current ChatGPT conversation as a provenance-bearing source in Brain. If your Brain already contains an OpenAI conversation export, that export becomes the historical baseline and Brain can identify and preserve browser activity that occurs after the baseline. Brain distinguishes authoritative exported history from incremental browser evidence. Browser-derived captures are labeled as post-baseline deltas rather than being presented as complete exports. Core behavior: Send the current ChatGPT thread to your paired Brain. Preserve raw source text before Brain interprets it. Keep the OpenAI export as the historical source of record. Detect newer or changed ChatGPT activity after the baseline. Deduplicate repeated captures and retain provenance. The extension communicates only with chatgpt.com and the paired Brain service at brain.floot.app for these functions.
