Best alternatives to CardGo in 2026
If you use more than one AI chatbot — ChatGPT for one thing, Claude for another, Gemini for a third — you've probably noticed you end up typing the same background information over and over: who you are, what you're working on, what tone you want. CardGo is a small browser add-on that lets you write that context down once, in a set of reusable "cards", and then drop it into any AI conversation with one click instead of retyping it every time. CardGo is a Chrome extension that stores personal/professional context in seven structured card sections (Profile, Now, Goals, Guidance, Memory, Timeline, Skills) and injects them into chats with ChatGPT, Claude, Gemini, Perplexity, and Grok. Cards are encrypted client-side with AES-256-GCM before anything leaves the browser, and the encryption key is generated locally and never sent to CardGo's servers, so the company itself cannot read your stored context. An AI-assisted "dream cards" feature helps draft the cards from a short prompt, and an on-device filter strips obviously sensitive data before it's attached to a message. The extension is currently in free early access with no paid tier announced yet.
