Hermit is an AI profile migration tool that solves the painful transition from ChatGPT to competing AI assistants. Targeted at power users, professionals, and developers who have built extensive conversation histories, Hermit converts exported ChatGPT data into ready-to-use profiles for Claude Projects and Gemini Gems. Its core value is preserving years of contextual learning—behavioral patterns, project knowledge, and personal preferences—that would otherwise be lost when switching platforms. By analyzing the full ChatGPT export, including projects and themes, Hermit generates structured profiles far richer than the shallow memory exports offered by ChatGPT itself. This enables a seamless migration where the new AI assistant instantly understands the user's history, working style, and current priorities.
The primary pain point Hermit addresses is the enormous context loss when users attempt to switch AI assistants. ChatGPT's built-in memory export provides only about 40 isolated facts, many with unknown timestamps, and no synthesis or structure. Outdated information persists without context, and behavioral nuances are entirely absent. For professionals who rely on ChatGPT as a design thinking partner, coding assistant, or strategic advisor, starting from scratch in Claude or Gemini means repeated explanations, lost project history, and inefficient onboarding. This problem is especially acute for users with hundreds of conversations across multiple projects, where tacit knowledge—like a user's thinking style, recurring themes, and current priorities—is embedded in the dialogue but inaccessible in a portable format. Without a tool like Hermit, migration becomes prohibitive.
Hermit's first major feature group is the AI Portrait, a comprehensive synthesis of the user's identity, thinking patterns, and behavioral instructions. The AI Portrait is generated by analyzing the entire conversation history, not just memory snippets. It produces a coherent narrative describing who the user is—their profession, goals, and recurring themes—along with actionable instructions for interacting with them. For example, "Lead with visual references when explaining abstract concepts" or "She processes decisions by writing them out." This feature goes beyond simple fact extraction to capture the user's working style and preferences. The benefit is immediate: upon importing the portrait into Claude's memory, the AI instantly adapts its communication and reasoning to match the user's natural workflow, eliminating the trial-and-error period of teaching a new assistant how to interact.

The second major feature group is Topic Profiles, which are generated per ChatGPT project or automatically detected theme. Each profile contains the context of conversations grouped by topic—such as "Career transition" or "Full stack development"—with word counts and conversation counts. Users can paste these profiles directly into dedicated Claude Projects or Gemini Gems, effectively migrating entire workflows. For instance, a user with a ChatGPT project named "Side project MVP" containing 18 conversations and 142K words gets a structured profile ready for Claude. This maps the user's organizational structure from ChatGPT into the new platform, preserving project-specific instructions, insights, and methodology. The benefit is that users don't have to manually recreate project contexts or remember what was discussed; Hermit automatically extracts the essence and presents it in a format that Claude and Gemini understand.
Hermit provides several additional capabilities that enhance the migration experience. The Claude Memory Import feature generates a single file optimized for Claude's memory system, covering behavioral instructions and identity summary in a format Claude natively understands. The Current Snapshot focuses on the user's last six months, highlighting active projects and current priorities while filtering out outdated noise—critical for contexts that evolve rapidly. Memory Bullets offers 25 atomic facts for Claude's quick-recall memory, ideal for frequently accessed personal information. Finally, the Import Guide provides step-by-step instructions for deploying profiles across Claude Projects, Claude Memory, and Gemini Gems. These features work together to give users a comprehensive toolkit, ensuring no aspect of their history is lost and that the migration is as frictionless as possible.
Hermit operates through a straightforward three-step workflow designed for minimal friction. First, the user exports their conversations from ChatGPT Settings, obtaining a conversations.json file containing their entire chat history. Second, they upload this file to Hermit's web interface, where it is processed locally and encrypted during analysis. The user is shown free stats and insights about their conversations, such as project breakdowns and topic distributions. Third, Hermit's AI synthesizes the entire export into structured profiles—including the AI Portrait, Topic Profiles, and Claude Memory Import. These profiles are presented for download and can be imported into Claude Projects, Claude Memory, or Gemini Gems with one click. The methodology emphasizes temporal awareness: Hermit distinguishes between active and concluded projects, ensuring the new AI assistant understands current priorities versus past contexts.
Concrete use cases illustrate Hermit's practical impact. A product designer with 2+ years of ChatGPT conversations can migrate to Claude and immediately get advice that references her design system work, career transition, and marathon training schedule. A developer with multiple ChatGPT projects can seamlessly transfer each project's context to dedicated Claude Projects, preserving code snippets, architecture discussions, and debugging history. Another user might leverage the AI Portrait to gain self-insight: seeing their own conversation patterns and thinking style synthesized can reveal blind spots or recurring themes. The outcomes include dramatically reduced onboarding time, more personalized AI interactions, and the confidence to switch platforms without losing institutional knowledge. Users report that Hermit's profiles contain 14x more context than ChatGPT's memory export, making the transition not just possible but superior.
Hermit targets power users of ChatGPT who are exploring alternatives: product managers, designers, developers, researchers, founders, and anyone with substantial conversation history who values contextual continuity. The tool works with both Claude and Gemini, supporting Claude Projects, Claude Memory, and Gemini Gems. The tech stack is web-based, with local encryption during processing. Pricing starts with free stats and insights; profiles are available from 19,90 €. Privacy is a core concern: files are encrypted during processing, never read by humans, auto-deleted after ~10 minutes, and all data wiped within 24 hours. In summary, Hermit solves the fundamental lock-in problem of AI assistants by making user profiles portable. It empowers users to choose the best AI tool for their needs without sacrificing the valuable context built over years of conversations.
Product managers, designers, developers, researchers, founders, and entrepreneurs who have invested significant time in building context within ChatGPT and want to migrate to Claude or Gemini without losing that history. Also suitable for power users of ChatGPT who wish to gain deeper insights into their own conversation patterns and thinking styles. Professionals in fast-moving fields where continuous context is critical—such as product development, software engineering, and strategic consulting—will benefit most from Hermit's ability to preserve temporal awareness and behavioral instructions.
