Why PromptVault

Everything your prompts deserve.

AI Improver

Paste any prompt and get an AI-improved version in seconds. Choose your LLM provider, pick your model, and watch your prompt transform — with optional clarification follow-ups for deeper, structured refinement.

Version History

Every improvement is tracked. View side-by-side diffs, restore previous versions, and add notes — full history for every prompt, nothing ever lost.

Side-by-side Compare

Run the same prompt through two different LLMs simultaneously. Compare outputs with a built-in diff viewer, then save the winner directly to your library.

Categories & Tags

Organize prompts with custom color-coded categories. Filter by target LLM, keyword tags, or full-text search — find any prompt in seconds.
