CardGo.AI
Reusable context cards for AI chats, end-to-end encrypted
Save your context once as encrypted cards, then attach the right one in ChatGPT, Claude, Gemini, Perplexity or Grok with the CardGo Chrome extension. Free to start.
Hey Product Hunt 👋
I built CardGo because I was tired of repeating the same context whenever I switched between AI tools.
CardGo lets you save useful context as reusable cards—for your work, projects, goals, preferences, and more. When an AI chat needs that context, you choose a card, preview what will be shared, and attach it to your message.
Your saved cards are end-to-end encrypted, so CardGo cannot read them. The extension does not read your conversations either.
CardGo works with ChatGPT, Claude, Gemini, Perplexity, and Grok. It’s free to start.
What do you find yourself repeatedly explaining to AI?
Thanks for checking out CardGo!
