## What Otter.ai Does

Otter.ai joins Zoom, Teams, or Google Meet calls as an AI meeting assistant. It
transcribes conversations, labels speakers, generates summaries, and extracts
action items. It is useful for business teams that want a searchable record of
meetings.

Otter.ai is not built for live OPI work. It does not capture ordinary phone-call
audio from agency portals or softphones, does not provide two-way translation,
and only supports four languages.

## What Interpreter Does

Interpreter captures the audio an interpreter hears and turns it into live text.
It supports OPI calls, VRI sessions, browser-based portals, softphones, Zoom,
Teams, Google Meet, and other audio sources.

Interpreter is designed for the moments where interpreters need to catch exact
details: medication names, dosages, addresses, dates, case numbers, policy
numbers, eligibility codes, and speaker intent.

## Pricing

Interpreter costs $0.40 per active hour. At 40 hours of active call time per
month, Interpreter costs about $16.

Otter.ai Pro costs $16.99 per month and includes 1,200 transcription minutes
with a 90-minute meeting limit. Business and Enterprise plans cost more and are
designed for team meeting workflows.

## Choose Otter.ai If

- You need AI notes and summaries for business meetings.
- Your meetings happen on Zoom, Teams, or Google Meet.
- You only need English, Spanish, French, or Japanese.
- You want post-meeting summaries and action items.

## Choose Interpreter If

- You are an OPI or VRI interpreter.
- You work phone calls, softphones, agency portals, or mixed audio sources.
- You need two-way translation.
- You need support for 60+ languages.
- You need HIPAA compliance without an enterprise plan.
- You want pay-as-you-go pricing instead of a monthly subscription.
- You need low-latency transcription while actively interpreting.

## Bottom Line

Otter.ai is strong meeting-notes software, but it solves a different problem.
Interpreter is built for professional interpreters who need real-time help during
live calls. For over-the-phone interpreting, Interpreter is the better tool.
