CogniMemo Extension adds long‑term memory to AI chat services such as ChatGPT, Claude, Gemini and DeepSeek. By typing @cogni in any conversation, users can retrieve saved notes, previous chats and imported content. The tool also archives AI dialogues, captures posts from X, and provides a floating assistant that can reference personal knowledge while browsing. All information is kept in a single searchable repository that remains under the user’s control.
