context

Good prompts accumulate in the wrong places — chat histories, scratch files, half-remembered phrasings. The ones worth keeping are exactly the ones that get lost.

promptvault gives them a single home: a personal library where a prompt lives, gets better, and stays findable.

approach

The loop is save, improve, refine. A prompt goes into the vault, an AI improver reworks it in place, and every improvement lands in its version history — nothing ever lost.

Around that core sit the organising tools: categories and tags for filtering, and side-by-side diffs, so a revision can be judged against what it replaced.

a prompt is improved where it lives — every improvement kept in its version history

result

A live app behind a sign-in: library, improver, compare, templates, categories. The landing page shows the shape of it; the vault itself is personal.

A prompt stops being a one-off. It becomes a small, versioned asset — refined over time and ready to reuse.
