AI chatbots in English, free and unlimited.
Yiaho has built several artificial intelligences to cover every need. What makes Yiaho unique: our AI is completely free and unlimited, so anyone can use it online, freely, and with no sign-up. The interface is dead simple to use, made for everyone and in English.
We have built several artificial intelligence tools that you use the way you would a chatbot. Each AI is set up to answer your needs as closely as possible. If an AI gets something wrong, you can contact our team to report it. We work every day to improve your experience.
The free online AI site, for everyone.
Nothing could be simpler! We built the Yiaho platform so that artificial intelligence is within everyone’s reach and easy to use online. A real virtual assistant: pick the AI you want from the menu at the top of the site, and write your request. Every conversational chatbot runs on its own pre-prompt so it answers your needs as well as possible. You get AIs that are already well guided, without having to write elaborate, sometimes tricky prompts yourself.
You can also use your microphone (the small icon next to the text bar) to talk to our AIs directly, without typing a word. It is that easy!
Yes, completely! Yiaho is a fully free AI, usable with no account and with no limits. A free AI, online and with no sign-up, easy to use, in English! On top of that, we collect no personal data.
We offer several generative AIs, including well known language models such as ChatGPT, ChatGPT 5 and GPT 5.6, which you can use for free, with no restrictions! Only image creation is part of Yiaho+, our ad-free plan.
Yes, with Yiaho+, our ad-free plan: you describe the image, the logo, the thumbnail or the drawing you want, and the AI creates it in a few seconds, in the format of your choice. The trial is free and needs no sign-up.
The process suits beginners: just describe in the text box what you want to see appear. The more precise the description, the better the result. The other AIs on the site, chat, writing, experts, characters, stay completely free.
Like every online AI, Yiaho relies on machine learning: it uses algorithms to analyze data, spotting patterns and correlations in order to make decisions or carry out specific tasks. Machine learning models are trained on input data to optimize their performance, which lets them take intelligent actions based on new data!
With stable, high performing tools and fast, smooth exchanges with our chatbots, Yiaho stands out as the best 100% free AI in English. If you want to know more about how this new technology works, read our article on the subject and understand everything about AI!
Our team works every day to create new artificial intelligences for your most common needs. In 2026 we added nearly seventy AI characters, choose your own adventure stories, new experts and more language teachers.
We also improve the AIs already online, moving them to the most recent models to get the best results.

Yes! On Yiaho, you get a free ChatGPT, in English, with no sign-up and with no limits.
We offer the best GPT language models, among them our free ChatGPT, ChatGPT 5 and GPT 5.6, all available without a subscription. To find them, open the “AI Chat” section of the menu, at the top of the site.
Yiaho gives you a whole range of AIs designed to answer precise needs.
Our math AI, for example, is specifically coached to handle math questions the right way.
The same goes for every other AI on the site.
To get the same results from a general AI like ChatGPT, you would have to build a complex prompt for each type of request, just to be sure of getting the best artificial intelligence has to offer on that kind of question.
On Yiaho, you skip the trial and error. No need to prompt like an expert! We do it for you.
We also pick the best AI available behind each of our specialized tools. Some artificial intelligences are better at calculation, others at generating text, others again at images. We choose the best API for each use, with a solid prompt to keep the AI on track.
By using Yiaho, you get the benefit of our expertise in AI and in prompting. You reach AIs specialized in demanding needs, and you save time.
And all of it for free. You have nothing to pay! What more could you ask for?
Yiaho+ is our premium artificial intelligence. With no advertising at all, it runs on the APIs of the best AI models available today (GPT 5.6 for example) and includes the creation of images, logos and thumbnails.
The interface is designed to make AI easy to use day to day. As on the classic Yiaho, you get artificial intelligences specialized in specific tasks (rephrase, spell checking, translation, and more), except that you switch from one feature to another in a single click, with no page reload and no ads on screen.
Yiaho+ is a subscription, made possible by our partner Nation AI (formerly ChatbotGPT). The trial is free and needs no sign-up.
If you would rather have a fully free AI, unlimited, but with ads, then the classic Yiaho is the best answer for you. In that case, try our free AIs such as our free ChatGPT.
