Can I sign up for free?

Yes! You can use the API for free on a limited trial. Simply add a credit card to your account at any time to upgrade from the trial.

An account on the free tier has access to our pre-recorded audio transcription and Audio Intelligence features using our Async /v2/transcript endpoint. It also has access to our streaming STT feature using our wss://streaming.assemblyai.com/v3/ws endpoint.

An account on the free tier can transcribe up to $50 in transcription and will be able to process up to five files concurrently. If you upgrade your account before using $50 in transcription any unused amount will be retained on your account.

Once you have transcribed $50 worth of files you will need to upgrade your account to continue using the API.
