Strengths and weaknesses
Granola

- Works with Zoom, Meet, Teams and in person
- Free plan keeps only 30 days of notes
- No audio recording to replay later

Granola listens to your meetings through your computer or phone's audio, so no bot joins the call. You jot rough notes as usual, and afterwards it merges them with the transcript into clean, structured notes using templates you choose. Chat across past meetings, share them in team Spaces, or send them to Slack, Notion or HubSpot. The free plan keeps only 30 days of history, and training on anonymized data is on unless you opt out.

Dia
- Calm, uncluttered design from the makers of Arc
- Data is stored and encrypted on your device
- AI partners are barred from training on your data
- New users' free plan has no AI features
- Better Days plan costs $100 a month
- Windows version is still an early build
Dia comes from the team behind Arc and puts an AI chat beside your tabs that can read what's open and pull in context from Slack, Notion and Teams. Its Morning Brief, meeting prep and deck building are aimed squarely at office work. Privacy is better than most AI browsers, with your data stored on your device. Since August 2026, though, new users get no AI on the free plan, and the Windows version is still young.
