Free & unlimited Grok 4

Want to use Grok for free, with no limits and no login? The chatbot at the top of this page lets you talk to Grok 4.20, the model from xAI, Elon Musk’s AI company. Type your question and keep the conversation going for as long as you like.

This isn’t a lookalike: Yiaho sends your messages to Grok through xAI’s official API. The site is funded by ads, which is how we keep it free for you.

What is Grok 4.20?

Grok is xAI’s family of AI models. Grok 4 came out in July 2025, and xAI has kept improving it since: Grok 4.20 arrived in March 2026. On Yiaho we use its “non-reasoning” version, built to answer everyday questions quickly and directly, without a long thinking phase. That’s the right trade-off for a smooth chat. xAI has since released newer, more powerful versions (up to Grok 4.7), available mainly through its paid plans and API.

What you can do with Grok for free

• Ask anything and get clear, direct answers.
• Write: emails, posts, cover letters, stories, speeches.
• Learn: have a concept explained, revise for an exam, check your reasoning.
• Code: write, explain or fix code.
• Translate and summarize texts in many languages.
• Think things through: compare options, brainstorm ideas, plan a project.

Grok on Yiaho vs grok.com and X

On grok.com and in the X app, Grok can be used for free within certain limits; advanced features and the most powerful models come with xAI’s paid plans, such as SuperGrok. On Yiaho there’s no account and no message counter: you chat directly with Grok 4.20.

In exchange, our version focuses on conversation: it doesn’t search the web or X, and it doesn’t generate images. For recent news or the weather, use Yiaho+.

How to get better answers

• Give context: who it’s for, why you need it, the format you want (a list, a table, a short email).
• Say which tone you want: serious, simple, funny.
• Work in steps on a big task, and steer after each answer.

Limits to keep in mind

Like any AI, Grok can be wrong while sounding very sure, so check important figures, dates and quotes. It doesn’t know about the very latest news. Don’t share personal or confidential information, and for medical, legal or financial questions, talk to a professional. Yiaho is an independent platform and isn’t affiliated with xAI.
