GTD Brain brings your Getting Things Done board into ChatGPT. Ask what's on your plate and it shows the exact slice you asked about — your inbox, your next actions, your projects, or who you're waiting on — rendered inline as part of the answer. Capture new items to your inbox in one line, move cards between columns, and mark things done, all from chat. Your board stays in sync with the GTD Brain web, Android, and iOS apps. Requires a GTD Brain account.
