Quick answer

Formstack Forms starts at $83 a month billed yearly for one builder, 25 forms and 1,000 submissions per form, with HIPAA as an add-on and over 300 integrations. FormsAI Pro is $12/mo billed yearly for unlimited forms and responses, three teammates and a custom domain. Choose Formstack for documents, e-sign workflows and compliance; FormsAI for price and respondent experience.

Formstack sells forms as part of a workflow suite: forms, documents and e-signatures, with Salesforce-native options and HIPAA available as an add-on. For regulated, process-heavy teams, that’s the point.

Most people choosing a form builder need fewer moving parts: forms people enjoy answering, payments, bookings, a sheet or a CRM at the end, and a sensible price. That’s what FormsAI is.
