GTD Brain is a calm home for everything on your mind — one inbox, five lists, and a weekly review that actually fits. Empty your head into a single inbox, by text or voice, then clarify each capture into a next action, a project, or something you're waiting on — the GTD workflow, without the friction. HOW IT WORKS • Capture everything — every thought and task goes into one inbox. Zero decisions at capture time. • Clarify and organize — turn captures into next actions tagged by context, and multi-step outcomes into projects with a pinned next step. • Do, with a clear head — open @desk, @calls or @errands and see only what you can do right now. ONE BOARD. FIVE LISTS. Inbox, Next Actions, Projects, Waiting For, Someday — the lists a trusted GTD system runs on. Capture by voice or text, filter by context, and run a guided weekly review that keeps the whole system trusted. GTD BRAIN PRO — SUBSCRIPTION Capturing, editing and organizing your board, and the guided Weekly Review require GTD Brain Pro, an auto-renewing subscription: • Monthly — $19.99 / month • Yearly — $143.99 / year (with a 1-month free trial) Prices may vary by region.
