Distraction-free writing, outlining and mind mapping with a built-in AI assistant
An elegant, button-light editor using Markdown-style syntax so you can lock in formatting in seconds and stay focused on the words.
Write free-form text and outlines in the same document, then convert any outline into a visual mind map with one click, using classic, tree or fishbone layouts.
Summarize, generate outlines, expand, condense, continue, polish, translate and correct your text, or brainstorm new ideas, all inside the editor.
Write on iOS, Android, desktop or web with automatic cloud sync, plus offline writing so no idea is lost without a connection.

The collaborative whiteboard built for product builders
AI Flowcharts, AI Mind Maps and AI Wireframes convert a short text prompt into structured, fully editable diagrams, branched mind maps, or web and mobile wireflows — no manual drawing required.
Boards host diagrams, flowcharts, mind maps, wireframes, embedded media and documents side by side, so a whole product narrative lives in a single shareable file.
Multiple teammates edit the same board simultaneously with live cursors, thread comments attached to specific objects, and mention-based notifications.
Drag-and-drop UI components let teams sketch screens, link them into clickable flows and iterate on product ideas before engineering commits to a build.
