Prompt Vault

Saves supported AI chats as local text, document, or static HTML archives — automatically for Founders or manually for Free users.

Prompt Vault automatically saves your AI conversations — ChatGPT, Claude, Gemini, Copilot, and Perplexity — as local files, so you never lose a good conversation to a cleared history or an expired session. HOW IT WORKS - Manual save — click once to download the current conversation - Autosave (Founder) — saves automatically when a chat ends, switches, or goes quiet, with your own idle delay - Multiple formats — .txt, .md, or .docx (Word), plus a static HTML archive that includes images and chart snapshots - Search your archive — find any saved conversation by keyword later PRIVACY BY DESIGN Your conversations are never sent to any server we operate — they're written straight to your own Downloads folder, the same as any file you download normally. No accounts, no tracking, no data collection. Free tier included (manual saves, 10/day); a one-time lifetime "Founder" purchase unlocks autosave and unlimited saves.
