Features

Custom Formatting

Get transcripts your systems can read. Standardize dates, phone numbers, currency, and URLs in the text itself, so nothing downstream has to clean it up first.

Use our API

Format your transcripts with less than 10 lines of code

Apply formatting rules in your transcription request and receive text that already matches the conventions your systems expect, with no post-processing step to maintain.

See how in docs

Dates, numbers, and contacts

Format dates in US, European, or ISO style, standardize phone numbers, control currency and decimal precision, and turn URLs into links.

See supported formats

Many rules, one request

Apply as many formatting rules as you need in the same call, or format a transcript you already have.

The accuracy was strong, but the great documentation and unique models like Auto Chapters and Sentiment Analysis is what really won us over.

Product Manager, Aloware

If you have an hour of content, the difference between 99% accuracy and 97% accuracy, it's a lot of time for that person to review. So you could cut down their workflow from taking half an hour, to 20 minutes, to 15 minutes — it's huge, right?

Investments in STT improvements always pay for themselves, since it is such a critical building block of the voice pipeline.

AssemblyAI's managed API endpoint and diarization won me over — something Whisper couldn't provide.
