Interpreter vs Otter.ai for interpreters

Otter.ai is an AI meeting assistant. It joins online meetings as a notetaker, writes up what was said and summarizes it. Business teams use it for standups, sales calls and all-hands meetings.

Otter announced HIPAA compliance in July 2025 for its Enterprise plan. In August 2025, a class-action lawsuit alleged that its notetaker records meetings without every participant's consent.

It's built to keep a record of meetings, not to help an interpreter on a live call.

Interpreter puts every word of your call on screen as people speak, with the tools to act on it. It's built for phone (OPI) and video (VRI) interpreters. It works with call audio you share from Chrome or Edge, any call app on a Mac or Windows computer, and supported Android apps. Nobody else on the call joins or installs anything.

Live translate shows both languages as people speak. Captions only shows what people say, and you click a caption to translate just that line. Each speaker's turns get their own color, side by side or stacked.

Before the call, set the Call topic, like medical, legal or insurance, and add the names and terms you expect to hear. Your glossary sets how a term is translated, up to 50 terms. During the call, press Ctrl K (⌘K on a Mac) for Quick lookup, keep a callback number in Notes, and press Space to pause. Paused time isn't charged. Interpreter is HIPAA compliant, SOC 2 Type II audited and GDPR compliant.

Otter is meeting-notes software, and business teams get real value from its summaries.

But it wasn't built for over-the-phone interpreting: a two-language call on your agency's softphone, where you need the words now, not a summary later.

Interpreter was built for that job. Names, case numbers and addresses stay on screen, so you hold less in your head call after call and avoid the overload that leads to burnout.
