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.

Human-friendly API client with an AI sidekick
Describe the call you want in plain English and let the assistant assemble method, URL, headers, auth and body.
Use the same account across the terminal binary, the desktop app and the browser app, picking whichever fits the task.
Human-friendly request syntax and colorized, formatted responses make debugging APIs faster than raw curl output.
Saved requests, environments, collections, export and import, path parameters and copy-as-command support day-to-day team workflows.
