Our pricing is usage-based. You buy credits (1 credit = $1 before discounts), and your usage consumes them down to the second at an hourly rate.
There are three ways to pay for the same Pro tier. Features are identical. Pay as you go bills at standard rates with no commitment; credit packs are a one-off purchase discounted by pack size; a subscription commits monthly or annually for the best per-credit price. .
Sign-up bonus, credit-pack credits and annual subscription credits last 12 months. Monthly subscription credits last 2 months.
When your credits run out on a subscription, your overages will be billed at your discounted rate at the end of the month. Otherwise, if you have a card on file, you’ll be billed any overages at the base rate at the end of the month. If you’re on the free tier, your API access will be paused once your credits run out.
It's an opt-in program that takes 33% off Speech to Text rates. By opting in, you grant permission for your audio and transcripts to be used to help improve our models; however, opting in does not guarantee that your data will be used for training. We may, at our discretion, store and use some, all, or none of the data you've made available. The discount applies regardless of whether your data is ultimately stored and used.
The program is off by default, can be reversed at any time, and applies only to future usage from the point of opt-in or subsequent opt-out. It doesn't apply to Text to Speech.
55+ languages for Speech to Text. See the full list in the docs.
We're certified to SOC 2 Type II, ISO/IEC 27001:2022, GDPR and HIPAA. Full details and additional documents (such as our DPA and Sub-BAA) are available in the Trust Center.
If you have not opted in to the model training discount program, Real-time inputs and outputs are never stored, and Pre-recorded data auto-deletes after 7 days or sooner via the API, and your data is never used to improve our models.
