Cohort

Group chats are great for conversation and terrible for memory. Cohort gives groups a private, shared archive for the links, ideas, research, memes, and discoveries worth keeping. Search everything later, vote, react, comment, and export the best of your collection as clean prompt-ready context for ChatGPT, Claude, Gemini, or Grok. Built for friend groups, startup teams, study groups, research circles, and communities.
