AssemblyAI vs Notta Comparison 2026
AssemblyAI is a speech to text API with no interface: send audio, get a transcript back, priced at $0.15 an hour with 185 free hours to build on. Notta is a finished app that records or ingests audio, transcribes over a hundred languages and adds an AI summary with action items, free for 120 minutes a month. One is infrastructure for a developer to build on. The other is a working tool for an interviewer who wants a summary the same afternoon.

AssemblyAI
Speech to text you call as an API
AssemblyAI is a speech to text API rather than an app: you send audio and get back a transcript, with speaker labels and summarisation available on the same call. Both pre-recorded and live streaming are covered, and the free tier is generous enough to build something real before paying anything. It is bought by people writing software, not by people who want a transcript this afternoon.
Our note
At fifteen cents an hour the price is not the thing to agonise over, so pick on accuracy for your audio and on whether you want speaker labels in the same call. Deepgram is the direct comparison and the two trade places depending on the recording.
Notta
Transcription and AI summaries by the minute
Notta records or ingests audio, transcribes it in over a hundred languages, and produces a summary with action items attached. Bilingual transcription and translation are what it is picked for over the English-first tools. The free tier's 120 minutes a month is one long interview, and everything above that is measured in minutes rather than in files.
Why people weigh these two
- Notta instead of AssemblyAI
- The same transcription job as an app rather than an API: by-the-minute transcripts with AI summaries, a free tier and plans from $8.17, no code required.
- AssemblyAI instead of Notta
- AssemblyAI is an API rather than an app, built for a developer wiring transcription into their own product instead of opening a dashboard to transcribe one file.
Which one should you pick
Choose AssemblyAI if you are writing software that needs transcripts, a product for creators or an internal pipeline, with speaker labels and summarisation on the same API call. It costs $0.15 an hour with no monthly plan, and the free tier covers 185 hours, far past what most projects need to prove themselves.
Choose Notta if you need a working transcription tool today, especially across two languages with translation attached, which the English-first tools do not do. Free covers 120 minutes a month, and Pro is $8.17 a month billed annually for 1,800 minutes and transcript export. Notta is the wrong tool for anybody transcribing hours a week, since everything is metered in minutes and that allowance becomes the binding constraint fast.
Common questions
- Which of these is built for a developer to integrate?
- AssemblyAI is the API itself: audio in, structured text out, priced at $0.15 an hour after 185 free hours. Notta is a finished app for recording, transcribing and summarising, built to be opened and used directly rather than integrated into something else.
- Which one handles more than one language in a single recording?
- Notta does. Bilingual transcription with translation attached is specifically what it is picked for over English-first tools. AssemblyAI is not positioned around bilingual handling in the same recording. Its strength is being callable from your own code at $0.15 an hour.
- How do the free tiers compare?
- AssemblyAI gives 185 free hours of pre-recorded transcription, aimed at a developer testing before writing a lot of code. Notta gives 120 minutes, 50 uploads and 10 AI summaries a month, aimed at somebody who wants one long interview handled for free.
- What happens when I go over Notta's free minutes?
- Pro is $8.17 a month billed annually at $97.99, or $10 billed monthly, and raises the allowance to 1,800 minutes and 100 uploads with transcript export added. Business goes to $16.67 billed annually for 200 uploads, with its own 7-day trial.
