TheBrain

TheBrain helps people arrange project information as a network of connected topics rather than a list of folders. You can collect notes, documents, web links, and other resources around an idea, then follow the relationships between them. It suits research, planning, and personal knowledge management when material belongs to more than one subject or needs to be revisited in context.

Connected topics keep relevant notes, files, and links in view as you move between projects.

Each topic can hold notes and attachments, while links between topics can carry their own details. Visual, outline, and timeline views offer different ways to browse the same material. Search, tags, filters, and reports help locate items; pins and history provide routes back to previous work. You can keep data locally, sync it across devices, export it as JSON, or share it through the web.

Features:

• Connect topics in an interactive visual map
• Attach files and web links to topics
• Add notes and details to topic connections
• Browse content in outline and timeline views
• Filter topics using tags and custom reports
• Sync data across devices or work offline
