TheBrain Help

Welcome to TheBrain's help. Every topic in this guide is a thought, so you can explore it the same way you explore your own brains.

In the Plex's Normal layout, the sections that hold a topic appear above it as its parents, and the topics inside a section appear below it as its children. Related topics from other sections appear on the left as jumps, and the other topics in the same section appear on the right as siblings. If you are new to TheBrain, begin with Start Here.

To read the whole guide as one note, print it, or download it as a PDF, see User Guide, which appears on the left of this thought as a jump.

• Start Here — A short path through the topics a new user needs first, from creating an account to writing notes and syncing.
• Brains and Thoughts — Create and manage brains, build their networks of thoughts and links, and describe each thought so it is easy to recognize and find.
• Capturing and Importing — Get ideas into TheBrain quickly from anywhere, and bring in notes and files from other apps.
• Exploring and Finding — Read and navigate the Plex, switch views and windows, move around a brain, and search for what you need.
• Notes and Attachments — Write and format notes, add tables, images, and other rich content, link notes together, manage note formats and versions, and work with attached files.
• Calendar, Reminders, and To-Dos — Add events and reminders to thoughts, see them on the Timeline, and track the checkboxes in your notes with the To-Do List.
• Cerebro AI Assistant — Chat with Cerebro, TheBrain's AI assistant, control what it may do, save reusable instructions, and understand usage limits.
• Syncing and Sharing — Keep brains in sync across your devices, work offline, share brains and thought pages with others, and collaborate with TeamBrain.
• Personalizing TheBrain — Change how your brains look with themes, and adjust settings for yourself, for each brain, and for each device.
• Account and Plans — Create and secure your account, sign in, and understand plans, billing, cloud capacity, and API keys.
• Keeping Your Work Safe — Undo changes, look back through the history of thoughts and notes, back up and export brains, and recover after a crash or an interrupted sync.
• Help and Troubleshooting — Get help and support, take the in-app tutorials, keep the app up to date, and fix problems with search, brain data, and crashes.
