Tree-structured knowledge,
one idea at a time.

Memory Cells organizes your thoughts as a tree — each cell holds one idea, and the hierarchy is the structure. No formatting needed.

Why Memory Cells?

🌳

Tree-First Architecture

Every piece of information lives in a tree. Parent-child relationships replace bullet lists, headings, and folders. Navigate naturally.

💡

One Cell, One Idea

Keep each cell focused and concise. The structure provides context — no need for in-cell formatting or markdown gymnastics.

Built-in Task Tracking

Any cell can become a task with todo/wip/done/cancelled status. Track progress across your entire knowledge tree.
