Build powerful forms, surveys and quizzes with AI in minutes
Describe the form you need in plain language and Zite generates a branded form with logic, file uploads, and payments.
Add conditional logic, intelligent routing, and multi-step workflows to automate what happens after each response.
Respondents can log in to update their answers, and forms can be restricted to internal users only.
Use custom themes, fonts, logos, custom CSS, your own domain, and embed forms as popups, sliders, or full-screen pages.

AI agents that run document-heavy business processes end to end
Agents read invoices, POs, remittances, claims and forms, then act on them — matching, approving and posting rather than only extracting fields.
Clean, validated data is written directly into systems of record including SAP, Salesforce, NetSuite, QuickBooks and Gmail workflows.
Policies, SOPs, system data and conversation history are stored as a governed graph so every agent decision cites the rule and document behind it.
Prebuilt flows for accounts payable, reconciliation, order management, cash application, supplier onboarding and claims processing.
