OwnTheSession
A boring, dependable vault that records every AI conversation you have across ChatGPT, Claude, Gemini, and Grok, and lets you export a self-contained transcript you can hand to another model, search, or delete.
Knowledge workers and consultants who run client work through AI and need their own auditable records
- Browser extension that captures the full transcript on each provider, including tool calls and search results, into a local archive
- Portable export in a single open-format file that another model can continue from without needing provider IDs
- One-click 'switch providers' workflow that helps you pick up a thread on a different model and warns about what state will be lost
Providers are quietly locking reasoning tokens, web-search sources, and subagent messages behind encrypted blobs, so users are losing ownership of their own work product.
Pain point is real but niche; the cited HN thread only scored 50 pts / 3 comments, and most power users already rely on each provider's native export (OpenAI, Claude, Google all ship export features).Exporting your ChatGPT history and data | OpenAI Help Center ↗Import and export your memory from Claude | Claude Help Center ↗

WTP exists (AI Toolbox sells a $199 lifetime All-Access bundle; ChatVault AI Pro has paid plans) but it's a low-LTV utility where many rivals are free or local-only, capping realistic revenue.The Best Way to Export All Your AI Chats (2026) - ai-toolbox.co ↗ChatVault AI Pro Checkout ↗
Providers are improving — not removing — export features (Claude and ChatGPT both ship native memory/history export), which gradually commoditizes third-party archives and threatens long-term differentiation.Import and export your memory from Claude | Claude Help Center ↗Chat Vault — Back Up & Save Your AI Conversations ↗
Technically straightforward: DOM-scraping Chrome extensions or CLI scrapers across well-known UIs, local JSON/Markdown storage, with several OSS reference implementations already public (e.g., dotCipher/ai-vault).GitHub - dotCipher/ai-vault: Own your data.
