Intercall and Unicaption were built for the same person — the interpreter mid-call who needs every name and number on screen. On paper they look alike. Here is where they actually differ.
If you've searched for an AI tool for interpreters, you've likely met both Intercall and Unicaption. Both caption live speech, both translate it, both run beside Zoom, Teams, Google Meet, or your agency's phone platform, and both say nothing is stored once the session ends. When two tools share a feature list, the decision comes down to how you pay, how you try, and what's already built in on day one. Those three questions settle it quickly.
Intercall is a live copilot for professional interpreters in medical, legal, government, and immigration work. According to its public site, it transcribes and translates both sides of a call in real time across 60+ languages, labels speakers, handles code-switching, and lets you preload custom vocabulary and session prompts before an assignment. It ships as desktop apps for macOS and Windows, a web app, and a Chrome extension, and it captures audio from meeting platforms or the system.
Its pricing is built around hours: plans include a monthly hour allowance and extra hours can be bought on top (check their current pricing page for rates and terms). A short free trial with no credit card lets you test it. Speaker labels and adjustable display settings are real strengths, and if you prefer paying by the hour, that model will suit you.
Unicaption starts from the same place: an interpreter's scarcest resource is working memory, so every word should be on screen instead of held in your head. Live speech-to-text appears as people speak, with automatic language detection across 60+ languages and the translation shown side by side with the original, so you check terms instead of guessing at half-heard phrases.
Terminology is ready from the first session. Medical, legal, and government vocabulary is built in, and a custom dictionary keeps your drug names, case names, and agency phrasing from one session to the next. A notepad sits beside the captions. It runs in the browser with nothing to install, as a Chrome extension, and as native macOS and Windows desktop apps, and it reads your microphone or system audio, so nothing joins the call.

On the core promise, these tools agree more than they differ. Treat every vendor's accuracy and latency numbers, ours included, as claims to check in a free session with your own language pair and audio. Our guide to word error rate explains how to judge that fairly.
Intercall. Speaker-aware captions are central to its product. If knowing exactly who said each line matters more to you than anything else, test it first.
Intercall. Its hour-based model with add-on hours suits people who think in billable hours. Check their current terms.
Unicaption. 30 free minutes renew every week with no credit card, so you can judge it across many real shifts, not one short trial.
Unicaption. Medical, legal, and government terminology is built in before you add a single term, and your custom dictionary keeps growing across sessions. See our medical interpreting guide.
Unicaption. Plans start at $9/month, billed monthly. The annual discount is optional.
For the interpreter whose laptop is their booth, Unicaption runs quietly under every assignment:
Both are real-time AI copilots for human interpreters with live transcription and translation in 60+ languages, desktop apps for macOS and Windows, a web version, and a Chrome extension. Intercall focuses on speaker labels and hour-based pricing. Unicaption offers 30 free minutes every week with no credit card, monthly plans from $9, side-by-side translation with tap-to-look-up, and built-in medical, legal, and government terminology.
Unicaption has a free tier that renews: 30 free minutes of live transcription and translation every week, with no credit card required. It runs in the browser, as a Chrome extension, and as macOS and Windows desktop apps, so you can test it on real calls for several weeks before paying anything.
Both are built for medical interpreting. Unicaption includes medical, legal, and government terminology out of the box and keeps your custom dictionary across sessions. Intercall lets you preload custom vocabulary before each session. For confidentiality, Unicaption is end-to-end encrypted, never stores audio, and deletes transcripts at session end. Always follow your agency's policy on aids.
Both say session content is not kept. Unicaption never stores audio, deletes transcripts when the session ends, never uses session content to train models, and encrypts sessions end to end. Intercall describes processing audio in memory only; see its compliance pages for details.
30 free minutes every week. No credit card, nothing stored.
