Pay for a year, pay 10% less. Starter, Standard and Pro can be paid annually: twelve months at the monthly fee less 10%, invoiced and paid up front. You choose monthly or annual when you open the account and whenever you change plan; a change of billing period takes effect when the current period ends. Free has nothing to discount, and Enterprise and self-hosted installations are on an annual contract agreed with you.
No user limit on any plan. A plan limits the number of keys — systems — and the volume of characters, never the number of people. The browser add-on comes with every paid plan, with no seat price.
The hard cap is on by default. Traffic stops rather than producing an invoice you did not expect; you switch overage on deliberately.
Your own provider key on every plan (BYOK). Through the SDK you call any model provider on any plan. Through the proxy, traffic on Free goes to the instance's provider; on every paid plan you set your own provider address per key.
Every feature is on every paid plan. From Starter up, custom formats, agent loops, a provider address per key, the browser add-on, OCR and any number of keys are included; plans differ in volume only — characters, the price of a character above them, requests a minute and the size of a request.
Scans are billed as text. OCR reads a scanned page and the characters it finds count towards your plan like any others; the page figure on a card is a monthly cap that protects the reading service, not a price.
Detection quality is identical on every plan. A cheaper plan is less volume, never weaker protection. The free plan needs no card.
