Observer vs Otter.ai
Observer helps while the call is still happening.
Otter is the established meeting notetaker.
Otter records and transcribes meetings so you and your team can search them later. Observer works in the moment: answers from the live transcript and your screen while people are still talking, then notes when the call ends.

What they are
Observer
A desktop AI companion for meetings on Mac and Windows. Quick Actions draft a reply, help with what is on screen, recap the last few turns, or look up a fact during the call. Playbooks shape the actions and notes for each kind of meeting, and nothing joins the call.
Otter.ai
An AI notetaker with live transcription, summaries, action items, and AI chat across meetings. Its meeting agent joins Zoom, Teams, and Meet as a participant, and the desktop app can record without one. Strong on team search and integrations like Salesforce, HubSpot, and Slack.
No bot in the call
Observer runs on your desktop and never joins as a participant. With Undetectable on, its window also stays out of screen shares and recordings.
Bottom line
Choose Otter if you want a searchable record of every meeting for your team, with CRM integrations and a free plan. Choose Observer if you want help during the conversation itself, from what is said and what is on your screen, with no bot in the call.
