How to Use Chai AI in 2026: Step-by-Step Guide
Mobile-first AI companion and roleplay chat platform with thousands of user-created AI personas.
Chai AI is a mobile-first social AI platform where users can chat with thousands of AI personas created by the Chai community or build their own. Popular for entertainment, creative roleplay, and AI companionship, the app hosts characters across every genre — from fantasy heroes to historical figures to original fictional creations. Chai uses its own fine-tuned models optimized for expressive, character-consistent conversation rather than factual accuracy. With tens of millions of downloads, it is one of the most widely used AI companion apps, especially among younger audiences exploring creative and social applications of AI.

Getting Started
Create Your Account
Visit https://chai.ml and sign up for a freemium account. You'll need an email address to register. A free tier is available — you can upgrade later for more features.
Start Your First Conversation
Once logged in, you'll see the main chat interface. Type a question or task in the input box and press Enter. Chai AI supports AI companions, roleplay, character creation, mobile, social AI, user-generated bots — start with a simple text prompt to get familiar.
Pro Tips
- Be specific: The more context you provide, the better the response. Instead of "write an email," try "write a professional follow-up email to a client who hasn't responded in two weeks."
- Iterate: If you don't get what you need, ask for clarification or refinement: "Make it shorter" or "Use a more formal tone."
- Use examples: Show Chai AI what format you want by including an example in your prompt.
- Save useful conversations: Most platforms let you name and revisit conversations — organize by project or topic.
