Interpreter vs InterpretBank: OPI Comparison (2026)
Quick answer
InterpretBank is terminology management software for conference interpreters. It helps you build glossaries, study flashcards, and look up terms during booth work. Its ASR add-on (BoothMate) transcribes speech and highlights glossary matches.
Interpreter is real-time transcription for over-the-phone interpreting. Every word on screen in under 500 ms, both speakers, both languages. No glossaries to build. No prep needed.
Different tools for different workflows. If you work the phones and need to stop scribbling notes mid-call, Interpreter was built for you.
What InterpretBank does
InterpretBank is a computer-assisted interpreting (CAI) tool with three modes. TermMode lets you create multilingual glossaries with AI-powered term extraction and translation suggestions. MemoryMode is a flashcard system to memorize terminology before assignments. ConferenceMode provides a distraction-free lookup interface for the booth.
It runs on Windows and macOS as a desktop app, with a web-based companion for searching glossaries on mobile devices. Conference interpreters use it to prep for specialized assignments where knowing the right terms beforehand is half the job. See InterpretBank pricing for current plans.
The ASR add-on (BoothMate / ASR 3.0) transcribes speech and highlights matching glossary terms in real time. The Basic engine has time-limited sessions; the Premium engine offers better accuracy with pay-as-you-go credits. Useful when you know your terminology in advance. Less useful on unpredictable phone calls.
What Interpreter does
Every word on screen, the moment it's spoken. Both speakers. Both languages. Sub-500 ms latency. No glossaries to build, no prep, no studying.
Turn it on, share your call audio through our Chrome extension, and watch the transcript appear. It catches everything — the medical terms you expected, the case numbers you didn't, and the addresses you'd normally have to ask to repeat. Speaker identification labels who said what. Click any word to translate it instantly.
Quick Lookup is the standout for terminology: tap any word mid-call to get a dictionary translation plus example sentences — no pre-built glossary required. Need your own mappings? Term Mappings lets you pin up to 50 custom word-to-translation pairs. Floating Notes gives you a draggable, resizable notepad on top of the transcript. Choose a call domain (Medical, Legal, Finance, Insurance, Government, Education, and more) to sharpen transcription accuracy. View the transcript Paired (side-by-side) or Interleaved (stacked). Assisted Mode (Polyglot Mini) adds push-to-transcribe in 100+ languages.
Browser-based, zero installation. Works with Zoom, Teams, Meet, your agency's VoIP portal, or any audio source. Built specifically for phone interpreters who are tired of the listen-write-interpret juggle that leads to burnout. Volume discounts on credit packages ($10–$100) give you 2–7% bonus minutes.

Pricing comparison
For an OPI interpreter working 40 hours/month:
$8–$14/month
Polyglot Mini: $0.20/hr ($8/mo). Polyglot: $0.35/hr ($14/mo). No subscription. 1 hour free to start.

InterpretBank's base price looks similar, but that covers glossary management — not live transcription. Adding Premium ASR credits increases cost, and you still don't get two-way translation or speaker ID. Use our earnings calculator to see what Interpreter costs at your volume.
Where InterpretBank wins
- You do simultaneous conference interpreting where terminology prep is essential
- You want to build and share multilingual glossaries across a team

Where Interpreter wins
- You're an OPI interpreter working phone calls or VRI sessions
- You want every word captured — not just pre-loaded glossary terms
- You need Quick Lookup and Term Mappings instead of building glossaries ahead of time
- You want domain-specific accuracy (Medical, Legal, Finance, etc.) without manual glossary prep
- You handle medical calls and need HIPAA compliance
- You need two-way translation with auto language detection and code-switching
- You want zero setup — browser-based, works with any audio source
- You prefer pay-as-you-go pricing without monthly subscriptions or credit systems
The real question
These tools solve fundamentally different problems.
InterpretBank is about preparation. Build glossaries, study terms, look them up during booth assignments. It assumes you know what vocabulary you'll encounter.
Interpreter is about execution. Capture everything during calls — prepared or not. Medication names, case numbers, addresses, dates. The stuff you can't predict and can't afford to miss.
Some interpreters use both — InterpretBank to prep, Interpreter to perform. But if you're doing OPI and have to pick one? Taking notes during calls is the harder problem. AI won't replace you, but it can take notes so you don't have to. That's what Interpreter solves.
FAQ
Can InterpretBank do real-time transcription like Interpreter?
InterpretBank's ASR 3.0 (BoothMate) transcribes speech, but it's designed to highlight glossary matches — not capture full conversations with two-way translation. It uses your microphone input, not system audio, so it can't tap into phone calls or VoIP platforms the way Interpreter can.
Is InterpretBank HIPAA compliant?
InterpretBank advertises GDPR compliance for its Premium ASR engine. It does not advertise HIPAA or SOC 2 compliance. If you handle medical interpreting calls in the US, check their current terms. Interpreter is HIPAA, SOC 2, and GDPR compliant.
Does InterpretBank work on phones and tablets?
InterpretBank's desktop app runs on Windows and macOS. A web companion lets you search glossaries on mobile devices, but the full TermMode/ConferenceMode experience requires the desktop app. Interpreter runs entirely in Chrome — any device with a browser works.
How does Quick Lookup compare to InterpretBank's glossary search?
InterpretBank requires you to build glossaries before a call — then searches them during ConferenceMode. Interpreter's Quick Lookup works the opposite way: tap any word mid-call to get a dictionary translation plus example sentences, no prep required. For terms you use repeatedly, Term Mappings lets you pin up to 50 custom word-to-translation pairs that appear automatically.
Can I use both tools together?
Yes. Some interpreters who do both conference and phone work use InterpretBank for glossary prep and Interpreter for live call support. They complement each other.
