PromptCard is a personal vault for storing, organizing, and sharing AI prompts across ChatGPT, Claude, and Gemini, with tagging, versioning, run tracking, and one-click forking.
The core idea
Most people manage their best prompts in scattered notes apps, docs, or Slack threads, and lose them the moment they switch tools. PromptCard gives every prompt a real home: a card with metadata, version history, and a record of how it's actually performed.
What's shipped
- Personal prompt vault with tagging and search
- Versioning and run tracking per prompt
- One-click forking, so a good prompt becomes a starting point instead of a dead end
- Public creator profiles for sharing a curated set of prompts
Where it's headed
- Prompt enhancement: AI-assisted rewriting, multiple alternative versions generated at once, and "refine with feedback" iteration
- Browser extension: use saved prompts directly inside ChatGPT, Claude, and other AI tools without copy-pasting
- Marketplace: creators sell or share prompt collections and simple micro-agents built from their own prompt library
- Notion integration: import and two-way sync a prompt library from an existing Notion database
Positioning
"Prompt OS for builders": a structured home for prompts, not just a gallery.
PromptCard is the personal-vault layer. A more advanced sibling product, PromptKit, is where prompts eventually get wired into CI/CD, testing, and production analytics.
