Speak once, get polished text anywhere you type
Speak inside Gmail, Slack, Notion or any other text field and have clean text appear where you were typing, instead of switching apps.
Convert raw speech into notes, emails, posts or meeting summaries using ready-made styles or your own saved formats.
Record up to around 90 minutes, get a transcript split by speaker, and generate a summary alongside the full text.
Language detection happens automatically as you speak, and you can switch mid-sentence without changing settings.
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.
