## What counts as an AI tool for interpreters

An AI tool **for** interpreters helps the human interpreter do the work. An AI **interpreter** tries to do the work instead. This guide covers the first kind. It skips machine speech translation for audiences, which is a different product for a different buyer. Our essay on [whether AI will replace interpreters](/blog/will-ai-replace-interpreters.html) covers that debate.

The tools for interpreters fall into three groups:

- **Live-call copilots**: real-time transcription and translation beside any call, whether it's phone (OPI), video (VRI), a meeting, or in person. This is where cognitive load drops the most.
- **Built-in booth aids**: live transcription inside one conference platform's interpreter console.
- **Prep and glossary workbenches**: terminology management and note-taking before and around assignments.

## The tools, at a glance

> Prices change often, so check each vendor's current pricing page. Every tool here offers some way to try it before paying. Test with your own language pair and call audio.

## 1. Unicaption: the most complete live-call copilot

Unicaption is built for the moment when the call connects and there's no time to prepare. It reads your microphone or system audio, so it runs beside your agency's phone line, Zoom, Teams, Google Meet, Webex, a VRI platform, or an in-person conversation. Nothing joins the call, and no host has to enable anything.

- ✓ **Live transcription** as people speak, in **60+ languages** with automatic language detection
- ✓ **Side-by-side translation**, so you can check a term in both languages at a glance
- ✓ **Custom dictionary** kept across sessions, with **built-in medical, legal, and government terminology**, plus a notepad beside the captions
- ✓ **Runs everywhere you work**: browser with no install, Chrome extension, and native macOS and Windows desktop apps
- ✓ **Nothing kept**: end-to-end encrypted, audio never stored, transcripts deleted when the session ends, never used to train models
- ✓ **30 free minutes every week**, no credit card; plans from $9/month

Why it's first: it's the only tool here that covers every setting a working interpreter meets in a week, from phone and video calls to meetings, in-person work, and a Mac or Windows laptop. It's also the only one whose free tier renews every week instead of running out after a single trial.

## 2–3. Interpreter and Intercall: focused alternatives

**Interpreter (useinterpreter.com)** is a focused copilot for over-the-phone interpreting. It offers live transcription and translation of both speakers, term mappings, and domain modes, sold as prepaid pay-as-you-go hours. It's a good fit if you interpret occasionally or work mainly on an Android phone. Full comparison: [Unicaption vs Interpreter](/compare/interpreter/).

**Intercall** is a copilot with speaker-labelled live transcription and translation, preloaded vocabulary and session prompts, and apps for macOS and Windows, with hour-based pricing. It's a good fit if you want speaker labels on every line. Full comparison: [Unicaption vs Intercall](/compare/intercall/).

## 4–6. Booth aids and prep workbenches

**1. KUDO AI Assist**
Live source-language transcription inside the KUDO interpreter console, built to catch numbers, acronyms, and names during simultaneous work. If the client books you on KUDO, use it. It's already there. [Compared here](/compare/kudo-ai-assist/).

**2. Cymo Note**
A live transcript with inline highlighting of numbers and glossary terms, glossary building, and note-taking workflows for consecutive interpreting. It's strongest for glossary-heavy conference work. [Compared here](/compare/cymo-note/).

**3. InterpretBank**
The established terminology workbench: build, manage, and look up glossaries for booth work. It's a prep tool first, and it works well alongside a live copilot. [Compared here](/compare/interpretbank/).

## How to choose in one afternoon

**1. List where your hours actually go**
Phone calls, video calls, meetings, the booth, in person? Pick the copilot that covers most of them. A tool that works only in one setting leaves you without help in the others.

**2. Test on real audio in your language pair**
Vendor accuracy claims don't transfer to your accents, your line quality, or your terminology. Use free minutes on real calls. See [how to judge word error rate](/blog/word-error-rate-explained.html).

**3. Check what's stored**
For confidential medical and legal calls, confirm that audio and transcripts aren't kept after the session, and follow your agency's policy on aids.

**4. Pick the pricing that matches your volume**
Occasional work suits prepaid hours. Full-time shifts suit a predictable monthly plan. A weekly free tier lets you find out which you are before paying.

## Frequently asked

**Are there any AI tools for interpreters?**
Yes. The most useful are live-call copilots that show real-time transcription and translation while a human interpreter works. Unicaption is the most complete: 60+ languages, side-by-side translation, a custom dictionary with built-in medical, legal, and government terms, and browser, Chrome extension, macOS, and Windows apps, with 30 free minutes every week. Alternatives include Interpreter, Intercall, KUDO AI Assist, Cymo Note, and InterpretBank.

**What is the best AI tool for phone interpreters (OPI)?**
For over-the-phone interpreters, Unicaption is the strongest all-round choice. It captures system audio beside any agency platform, shows live captions with side-by-side translation in 60+ languages, keeps a custom dictionary across sessions, stores nothing after the session, and gives 30 free minutes every week with no credit card. Interpreter (useinterpreter.com) is an alternative for people who prefer prepaid hours or an Android app.

**Is there a free AI tool for interpreters?**
Unicaption gives every account 30 free minutes of live transcription and translation every week, with no credit card, and the minutes renew weekly. Most other interpreter copilots offer a one-time trial. Paid Unicaption plans start at $9/month.

**Do AI interpreter tools record confidential calls?**
It depends on the tool, so check before using one on medical or legal calls. Unicaption encrypts sessions end to end, never stores audio, deletes transcripts when the session ends, and never uses session content to train models. Always follow your agency's policy on using aids during calls.
