## What InterpretBank is built for

InterpretBank grew out of academic research on computer-assisted interpreting and has been a fixture in conference work and interpreter training for years. Its center of gravity is terminology. Multilingual glossaries live in a local database with optional cloud sync. AI-assisted term extraction pulls candidate terms from the PDFs and Word documents an assignment sends you; AI can draft a glossary from nothing but a topic description; contextual translation suggests equivalents while you refine it. A memorization mode turns finished glossaries into flashcard study before the assignment, a booth mode strips everything down to fast, distraction-free lookup mid-assignment, and it will even generate practice speeches seeded with your glossary terms. It ships as desktop software for Windows and macOS, with a web app for lookup on tablets and phones.

Two more things worth crediting. First, InterpretBank is not prep-only: it offers live speech recognition that highlights numbers and glossary terms as they are spoken — genuinely useful in a booth, and available in local as well as cloud modes. Second, licensing is flexible: subscription or a perpetual one-time license, with details on their pricing page. If your work is conference interpreting with real preparation materials, this depth is not something we will pretend to match. For the prep phase, use them.

## What Unicaption is built for

Unicaption starts where preparation ends: the moment someone is actually speaking. It transcribes live speech at state-of-the-art streaming accuracy, moments behind the speaker, with automatic language detection across 60+ languages and live translation shown side by side with the original. A custom dictionary improves recognition of your names and recurring terminology across sessions, with medical, legal, and government vocabulary built in, plus a notepad beside the captions.

It runs in the browser with nothing to install, as a Chrome extension, and as native macOS and Windows desktop apps. Because it reads your microphone or system audio, it sits beside any platform — your agency's OPI line, Zoom, Teams, Google Meet, Webex, a VRI session, or an in-person conversation — and nothing joins the call. Sessions are end-to-end encrypted, audio is never stored, transcripts are deleted when the session ends, and session content is never used to train models. Unicaption is end-to-end encrypted with nothing retained after the session.

## Two phases of the same job

The clean way to see the difference is by each tool's core object. InterpretBank's is the glossary: built before the assignment, memorized on the train, looked up in the booth, kept afterward and refined for next time. Unicaption's is the live transcript: it exists only while the call runs, gets translated as it appears, and is deleted the moment the session ends. One tool accumulates knowledge; the other handles the moment.

- **Prep phase — InterpretBank's home turf.** Conference documents arrive days early. Terms get extracted, translated, organized, and drilled before you ever open the channel — the workflow our [interpreter prep checklist](/blog/interpreter-prep-checklist.html) walks through.
- **Delivery phase — Unicaption's.** Agency OPI and VRI work arrives with no documents and no warning: a hospital call at 9:04, an insurance call at 9:21. There is nothing to prep; the help has to happen live.
- **Both phases, one career.** A conference booth on Tuesday and phone shifts on Thursday is a normal week now. Tools that own different phases don't conflict — they stack.

## The differences that actually decide it

| Dimension | InterpretBank | Unicaption |
| --- | --- | --- |
| Built for | Terminology and preparation, from documents to booth | The live call — captioning and translation while you interpret |
| Core object | The glossary: built, memorized, kept, refined | The live transcript: on screen during the call, deleted after |
| Live speech recognition | Highlights numbers and glossary terms as they're spoken | Full transcript at state-of-the-art streaming accuracy, moments behind the speaker |
| Translation | AI translation suggestions while building glossaries | Live side-by-side translation of the whole conversation, 60+ languages |
| Terminology | Deep workbench: extraction, AI glossary drafts, flashcard memorization | Custom dictionary across sessions; medical, legal, government vocabulary built in |
| Platforms | Windows and macOS desktop; web app for mobile lookup | Browser, Chrome extension, native macOS and Windows desktop apps |
| Licensing | Subscription or perpetual license — check their pricing page | Plans from $9/mo; 30 free minutes every week, no credit card |
| Data posture | Glossaries local by default; see their site for cloud specifics | Audio never stored; transcripts deleted at session end; end-to-end encrypted |

One caution that cuts both ways: vendor accuracy claims — ours included — mean little until you have tested with your own language pair, accent mix, and audio chain. Both products can be tried before paying; run a real assignment through each phase before deciding anything.

## Decide by scenario

**1. Conference assignments with real prep materials**
InterpretBank. Term extraction from the speaker's slides, an AI-drafted glossary you refine, flashcards on the train to the venue — this is the workflow it was built around, and nothing in Unicaption replaces it.

**2. You want terminology drilled before, not looked up during**
InterpretBank. Its memorization mode exists precisely so the term is in your head when the sentence arrives. Unicaption helps you verify live; it will not study with you the night before.

**3. Agency OPI or VRI shifts with zero warning**
Unicaption. No documents, no prep window — just the next call. Live captions with side-by-side translation, moments behind the speaker, running quietly beside your agency's platform.

**4. You need the whole conversation translated live**
Unicaption. InterpretBank's live features center on surfacing your prepared glossary; Unicaption puts every sentence on screen in both languages, with automatic language detection across 60+ languages.

**5. You work both worlds**
Use both — honestly. Prepare conference assignments in InterpretBank; run Unicaption beside live calls. They occupy different phases of the job and never fight over the same minute. More head-to-heads live on our [comparison hub](/compare/).

## Where Unicaption fits the delivery phase

When the preparation is done — or was never possible — Unicaption is the layer that keeps every word in sight during the call itself. A [custom dictionary](/blog/custom-dictionary-terminology-accuracy.html) carries your recurring terminology into recognition, and the rest is built for the live moment:

- ✓ **Every word on screen** — live transcription that appears as the words are spoken, in 60+ languages with automatic detection
- ✓ **Side-by-side live translation** so you verify a rendering instead of trusting a half-heard phrase
- ✓ **Terminology that persists** — your names, drug names, and case vocabulary kept across sessions, with medical, legal, and government terms built in
- ✓ **Runs beside anything** — microphone or system audio; your agency's platform, Zoom, Teams, Meet, Webex, VRI — nothing joins the call
- ✓ **Nothing retained** — end-to-end encrypted; audio never stored, transcripts deleted when the session ends
- ✓ **30 free minutes every week, no credit card** — enough to test it on real assignments before deciding

## Frequently asked

**Is InterpretBank a competitor to Unicaption?**
Only partially. InterpretBank is computer-assisted interpreting (CAI) software centered on terminology — glossary building, AI term extraction, memorization, and booth lookup, plus live recognition that highlights numbers and glossary terms. Unicaption is a live captioning and translation copilot for the call itself, storing nothing afterward. They overlap at the live moment but own different phases of the job, and many interpreters could sensibly run both.

**Does Unicaption do glossary preparation like InterpretBank?**
No — and it doesn't try to. Unicaption's custom dictionary improves live recognition of your names and recurring terminology, and medical, legal, and government vocabulary is built in, but it is not a preparation workbench: no document term extraction, no flashcard memorization, no glossary database to build and refine. If deep terminology prep is the job in front of you, InterpretBank is the right tool for that phase.

**Does InterpretBank do live transcription too?**
Yes — per their site, InterpretBank offers live speech recognition that highlights numbers and glossary terms as they're spoken, in cloud or local modes. The emphasis differs: InterpretBank's live features support booth work against a glossary you prepared; Unicaption delivers a full live transcript with side-by-side translation for calls where there was nothing to prepare. Which fits depends on whether your live work is prepared conference assignments or unpredictable OPI and VRI calls.

**Can I use InterpretBank and Unicaption together?**
Yes, and it's a coherent setup: build and memorize glossaries in InterpretBank before the assignment, then run Unicaption beside the live call for full captions and side-by-side translation. Unicaption reads your microphone or system audio without joining anything, so nothing conflicts. As always, follow your client's or agency's own policies on tools during assignments.

**Is Unicaption free to try?**
Yes — every account gets 30 free minutes of live captioning and translation each week, with no credit card required, and the free minutes renew weekly rather than running out once. Paid plans start at $9/month when you need more.
