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 AI workspace where teams and agents get work done together
Combine docs, wikis, projects, and databases into one structured system of record that stays linked as your content grows.
Draft, summarize, translate, and answer questions inline, or build custom agents that automate recurring workflows around the clock.
Find answers instantly across Notion and connected apps, with citations so you can verify where each answer came from.
Use relations, rollups, views, and a large template gallery to model anything from a CRM to a content calendar.
