Yeschat

Chat GPT Online – Free Chat with GPT Models

Ask questions, write, translate, code and study with OpenAI GPT models in your browser. YesChat is not ChatGPT itself: it is a separate service with GPT models and other AI models in one place.

What Is Chat GPT Online on YesChat?

YesChat is an independent service, not an OpenAI product. The chat box above lets you ask a GPT model a question right on this page. In the full YesChat chat you can also pick the GPT model you want, switch to other model families and use agent mode for files and slides. If you just want a free AI chat with no particular model in mind, see the free AI chat page.

What You Can Do with GPT Chat on YesChat

Ask right here

Type a question in the chat box at the top of this page: explain a topic, rewrite a paragraph, translate a message or check a piece of code.

A free GPT model every day

A free YesChat account includes 15 messages a day with GPT-5.6 Luna. The limit resets daily and you do not need a credit card.

Choose stronger GPT models in the chat

In the YesChat chat, paid plans add GPT-5.6 Terra and Sol, and the Max plan adds GPT-6 Astra, for longer and harder tasks such as analysis and coding.

Agent mode for files and slides

Agent mode in the YesChat chat is included on every plan: it reads screenshots and scans, summarizes PDFs with page references, cleans and charts Excel or CSV data, searches the web with sources and drafts slides as an editable .pptx.
