Chat with any PDF, video, or website and get cited answers in seconds
Every response is anchored to your source document with clickable citations that scroll to the exact passage, so verification takes seconds instead of page-by-page searching.
Organize documents into folders and query many files in a single conversation to compare arguments, cross-reference findings, or study a whole syllabus at once.
Condense long papers, reports, and contracts into key takeaways, and translate or query documents in any language — including mixing a source language with a different question language.
Generate flashcards and slide decks from your material, and use the built-in AI writer and AI detector for drafting and checking academic text.
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.
