Tetra - Automatic Call Notes

By Tetrachrome, Inc.

This app is only available on the App Store for iOS devices.


Tetra uses AI to take notes on phone calls, to help you focus, remember the details, and keep your team in sync.

Dial through the app and pay full attention to the call, as Tetra captures your conversation with revolutionary speech recognition. Tag highlights and action items with a single tap when you hear them. Then, get your notes back within minutes, so you can recall important details and share knowledge with your team.

- Engage in the discussion, without getting distracted writing it all down. Tetra recognizes the entire conversation so you’ll never forget a date or miss a follow-up later.
- Tag highlights and action items with a single tap, to skip the busywork and effortlessly copy notes into your CRM or task tracker.
- High definition VoIP connects you with your recipient with crystal clear audio quality, all over WiFi or 4G.

- Smart natural language search helps you instantly jump back to key moments in your conversation.
- Word Sync intuitively allows skimming the transcript and reviewing the audio recording at the same time.
- Tetra notes are automatically synced between mobile and web, so you can remember the details wherever you are.

- Spread knowledge and keep everyone on the same page by sharing Tetra notes with team members, even if they couldn't make the call. Tetra helps you keep an accurate record of everything that happened.
- Hear the voice of the customer directly to help your team focus on what matters.
- Just forward the highlights in the Meeting Digest email to colleagues, or invite them to collaborate on the notes in-app or on the web.
