All things about Chatex
Chatex is a browser-based AI workspace that combines multiple model families and tools in one place.
Use the model selector to choose among the current supported AI model families.
Chatex currently includes AI Search, Image Generation, PDF Chat, Video Generation, and a music tool that is still coming soon.
Chatex Pro is the paid subscription that unlocks ongoing access after the free message and enables paid-only product access such as PDF Chat.
Yes. Your subscription is tied to your account, not to one device.
Chatex is a web app only. There is no official iOS or Android app. Use it in mobile browsers.
Your one free message is a single first-use allowance across supported chat and free-access tool flows.
Use the Chatex model selector to match the current model family to writing, coding, reasoning, research, or speed.
Attachments depend on your current access level and on whether the selected model supports them.
Chatex chat currently accepts images, PDF, CSV, and TXT files up to 20 MB.
Some Chatex AI tools are available during free access, while others require sign-in, Pro access, or both.
PDF Chat lets signed-in Pro users upload a PDF and ask grounded questions about that document.
