PromptVault — Prompt Library for AI Chats

PromptVault is a fast, private prompt library for people who use AI chat every day. Stop retyping the same long prompts. Save them once, then drop them into any AI chat box instantly. ■ How it works • Save prompts with a title, folder, and tags • Insert into ChatGPT, Claude, Gemini, or Perplexity — click "Insert" in the popup, or type "/" in the chat box and pick one • Use {{variables}} in a prompt — PromptVault asks you to fill them in before inserting • Organize with folders and search; import/export your library as JSON ■ Built for AI power users and developers Code-review prompts, PRD templates, "explain this error", summarize-thread, rewrite — keep your best prompts one keystroke away. ■ Private by design PromptVault never reads your conversations or any page content. It only inserts the prompts YOU saved into the input box. Everything is stored locally in your browser. No account, no tracking, no servers. Free to use with up to 15 saved prompts. Pro (unlimited prompts, folders, variables, sync) coming soon.
