Pricing questions

How do credits work?

One credit checks one file up to 25,000 characters, or generates follow-up questions on a report. Longer files (up to 75,000 characters on paid plans) use 1 credit per 25,000 characters. Failed model runs are refunded automatically.

What does Business unlock over Pro?

Business is built for automated pipelines and high-volume grading: it includes 1,200 credits/month (4x Pro), full REST API access (/api/v1/*) with API key management, 200-file batch uploads, and 24-month history retention.

Do credit packs unlock batch checks too?

Yes. Buying any one-time credit pack permanently unlocks Pro editing and batch limits: up to 75,000 characters per check, 50-file batch ZIP uploads, CSV export, and 12-month history retention.

Can I cancel my subscription anytime?

Yes. You can cancel anytime from Settings before your next billing date. You keep your remaining credits until the end of the current billing period.

1 credit = 1 check of one file. If every model fails, the credit is refunded. Prices in USD.
