AI isn't replacing the interpreter. It's giving interpreters a second screen. Here are the tools worth trying, grouped by the job each one actually does.
Ask around for AI tools for interpreters and you'll get a jumbled list: machine translation apps, meeting captioners, glossary software, and a few tools actually built for the person doing the interpreting. Those are different jobs. The tools that matter most in 2026 are live-call copilots: software that puts every word, name, and number on your screen, translated, while you interpret. Below, each tool is grouped by the job it does, so you can build the kit your work needs.
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 covers that debate.
The tools for interpreters fall into three groups:
| Tool | Job | Best for | Where it runs |
|---|---|---|---|
| Unicaption | Live-call copilot | Interpreters across OPI, VRI, meetings, and in-person work | Browser, Chrome extension, macOS and Windows apps |
| Interpreter (useinterpreter.com) | Live-call copilot | Phone interpreting on prepaid hours | Browser, Chrome extension, Android app from their site |
| Intercall | Live-call copilot | Interpreters who want speaker labels and hourly billing | macOS and Windows apps, web, Chrome extension |
| KUDO AI Assist | Booth aid | Simultaneous interpreters working on KUDO | Inside the KUDO interpreter console |
| Cymo Note | Workbench and live aid | Conference interpreters focused on glossaries and notes | See Cymo's site |
| InterpretBank | Prep workbench | Terminology management and booth glossary lookup | Desktop |
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
30 free minutes every week. No credit card, nothing stored.
