Switching from ChatGPT to LibreChat

Clone the repo, copy `.env.example` to `.env`, set `OPENAI_API_KEY` (or point `OPENAI_REVERSE_PROXY` at a local Ollama / LiteLLM URL), then `docker compose up -d`. LibreChat speaks to OpenAI, Anthropic, Google, and any OpenAI-compatible local server side by side; users pick the model per conversation. ChatGPT export.zip can be partially imported via the conversation import endpoint (one JSON per thread).

Good fit for: Power users who want one chat UI in front of many providers — switch models mid-conversation, fork threads, plugin support.
Weak at: Heavier stack (Mongo + Meilisearch + RAG service) — overkill for single-user installs.
