Hermit – Preserve and transfer your full ChatGPT context across LLMs

Summary: Hermit processes your entire ChatGPT data export to generate structured, temporally aware profiles for each project and theme, enabling seamless migration of context to other LLMs like Claude and Gemini. It provides richer memory transfer than Anthropic’s Import Memory prompt and supports free analytics of your ChatGPT history.

What it does

Hermit analyzes the full conversations.json export from ChatGPT, creating detailed profiles with active and past labels for projects and recurring themes. It outputs ready-to-paste files compatible with Claude Memory, Claude Projects, Gemini Gems, or any LLM accepting system prompts.

Who it's for

Users switching between LLMs who want to retain years of conversational context, including projects, preferences, and personal data, without losing information during migration.

Why it matters

It solves the problem of context loss when changing LLMs by preserving temporal awareness and providing a more comprehensive memory transfer than existing tools.
