ChatGPT Conversation History Importer for Self-Hosted Open WebUI, LibreChat, and AnythingLLM After the QuitGPT Exodus
Google and Anthropic both shipped official ChatGPT history importers in March 2026, but only into their own clouds — Gemini and Claude. The 700,000+ users who pledged to quit ChatGPT and migrate to local-LLM frontends (Open WebUI, LibreChat, AnythingLLM) have to do it manually, because no importer parses OpenAI's ZIP export into self-hosted conversation stores. This is a one-weekend tool with a built-in audience.
Ship for ONE target (Open WebUI's Postgres schema) first, not all three. Open WebUI has the largest installed base and the schema is stable. Don't overthink the model — preserve the conversation tree as-is, you don't need to re-embed everything. Distribute as a single Docker one-shot that mounts the export ZIP and the Open WebUI volume, drops a migration row, and exits.

Every commercial importer routes you into another cloud. The self-hosted frontends most QuitGPT migrants are actually moving to (Open WebUI, LibreChat, AnythingLLM) have no first-class importer despite open feature requests.
