AI context cards for ChatGPT, Claude, Gemini, Perplexity and Grok
Ahrefs Domain Rating set in type 2 Nov 2026, reset 1 Nov 2026.
A Chrome extension that lets you save context once as encrypted cards and attach them to conversations across multiple AI chatbots.
CardGo is a context management tool for AI users who work with multiple chatbots. Instead of re-explaining yourself to each AI, you save your context once as encrypted cards—with sections for profile, goals, guidance, and more—and attach the relevant card to any conversation. Cards stay encrypted on your device and are only sent to an AI when you choose to attach them. The Chrome extension works with ChatGPT, Claude, Gemini, Perplexity, and Grok on desktop Chromium browsers.
Pricing model: Freemium
Free plan: $0 forever, 7 cards, CardGo AI: 10 messages and 10 hosted analyses a day. Pro plan: $9.90 per month, 50 cards, CardGo AI: 100 messages and 100 hosted analyses a day. Max plan: $19.90 per month, Unlimited cards, CardGo AI: 300 messages and 300 hosted analyses a day.

A short, structured block of context you want an AI to have, containing profile information, what's happening now, goals, guidance, memory, timeline, and skills. You write it once and attach it to a conversation when relevant.
CardGo works with ChatGPT, Claude, Gemini, Perplexity and Grok through the Chrome extension on desktop Chromium browsers such as Chrome, Edge, Brave and Arc. Mobile browsers cannot run extensions.
No. CardGo never reads your chat history or the AI's replies. It only looks at the message box and your unsent draft to suggest a card, and nothing is attached until you choose it.
Yes. CardGo is free to start with no credit card required. The Free plan includes up to 7 end-to-end encrypted cards that sync across your devices.
