Ctxia — AI Memory for ChatGPT & Claude

Save, organize, and reuse AI conversations from ChatGPT, Claude, Gemini, and DeepSeek with AI-powered knowledge cards.

Ctxia — Turn AI Conversations Into Reusable Knowledge AI conversations often contain ideas, decisions, explanations, research, and solutions that are worth keeping. But useful information can become difficult to find once it is buried in long conversations. Ctxia helps you save the parts of your AI conversations that matter and turn them into reusable knowledge. Capture What Matters When you find something worth keeping, save the conversation or select the specific content you want to preserve. Ctxia lets you decide what becomes part of your personal knowledge collection. Create Knowledge Cards Saved content can be organized into structured knowledge cards. Source Cards preserve the original content you selected from a conversation. Insight Cards help turn selected content into a clearer and more concise form, including key ideas, conclusions, decisions, context, and next steps. You choose when content is saved and when AI processing is used. Organize Your AI Knowledge Ctxia brings useful information from your AI conversations into one place. You can keep related ideas together, edit saved cards, and build on information collected from different conversations. Ctxia currently supports conversations on ChatGPT, Claude, Google Gemini, and DeepSeek. Reuse Previous Thinking Your saved cards are designed to be useful beyond the conversation where they were created. You can search and review saved cards, edit their content, copy information into your workflow, insert saved knowledge into supported AI conversations, and return to the original conversation when needed. Instead of repeatedly searching through old chats, you can bring previous thinking back into your current work. Privacy by Design Ctxia is designed to give you control over what is saved and processed. Content is handled when you explicitly choose an action such as saving content, creating a card, refining selected content, or exporting information. Your saved cards are stored locally in your browser. Ctxia does not automatically collect or scan your entire conversation history in the background. Product analytics do not include your conversation content, card content, prompts, AI responses, or search text. For more information about privacy: https://ctxia.io/privacy Why Ctxia? AI assistants are excellent at helping you think through a problem, but the useful results of those conversations can easily disappear into chat history. Ctxia gives those results a place to live. Capture useful moments. Organize your thinking. Reuse what you have already learned. Turn AI conversations into knowledge you can use again.
