PromptVault
Local-first prompt storage and organization
A browser-based tool for storing and organizing AI prompts. Built local-first: all data lives in IndexedDB, so there are no accounts, no backend, and no network dependency. Prompts are organized with tags and versions, with client-side search over the whole collection.
Key Outcomes
- Local-first architecture — all data in IndexedDB
