PrePrompt is an open-source tool that sits between you and your LLM inside Claude Code and Cursor.
PrePrompt solves a real, daily problem — vague prompts lead to wasted rework and token spend. If you live in Claude Code or Cursor, plugging it in is worth trying. It's free to self-host, though you'll pay small Haiku fees for each rewrite. Being a public beta means it's promising but not yet polished.
