Learn with AI: homework, revision and languages, for free

A math problem that will not budge, an essay due on Monday, a thesis to structure, a language to practice before a trip, a history chapter to revise: this page brings together every AI to learn with that Yiaho offers, free and with no sign-up. They are built for middle school and high school students, for college students, and just as much for adults picking a language back up or preparing a career change.

Each tool is a specialized AI with instructions written by Yiaho: the math teacher walks through every step instead of handing over the answer, the English teacher corrects you and explains the rule behind the correction, the career counselor asks questions before it suggests anything. The most recent tools run on GPT-5.6 Luna, an OpenAI model.

Learn with AI: which tool for which need?

For homework, the Math AI solves an exercise step by step and explains a concept another way when the first way did not land, and the physics and chemistry teacher does the same with formulas, units and diagrams. For written work, school and college writing helps you find an outline and real arguments, the university thesis tool follows you from the research question to the bibliography, and the internship report gives your experience a clear shape. To revise, Summarize a class turns a chapter into a study sheet, and the spelling corrector reads your work and explains each mistake.

For what comes next, the career counselor talks through majors, jobs, applications and career changes without locking you into a box.

Learn a language with AI

Eight language teachers are available, from English to German, by way of Spanish and Italian, but also Portuguese, Russian and two regional languages, Corsican and Alsatian. Each one corrects you live, explains the rule and matches its level to yours, from the first word to a fluent conversation. They are all gathered on the Learn a language with AI page, with the multilingual translator.

Revise history and mythology by talking to the characters

This is by far the most enjoyable way to remember anything: ask your questions directly to Napoleon, Joan of Arc, Julius Caesar, Leonardo da Vinci, Marie Curie, Albert Einstein or Socrates. They answer school questions accurately, in character, before adding the kind of detail that makes a date stick, and they name their sources. The Greek, Norse, Egyptian and Japanese gods do the same for mythology, starting with Zeus. They are all gathered on the AI characters page.

How to learn well with AI

Ask for the method before the answer: “explain how to do this” gives you far more than a result you copy. Have your own drafts corrected rather than having the AI write in your place, which is what teachers are looking for and what actually makes you better. Check important dates, figures and references against your textbooks, because an AI can be wrong with complete confidence. Work in short sessions and come back the next day: a tool that answers instantly is still no substitute for spacing your revision out. And for graded work, stay inside your school rules on the use of AI.

Frequently asked questions about the AIs to learn with

Is it free? Yes, with no sign-up and no credit card, within the fair use limit set for each tool.

Does the AI remember my lessons? During the conversation, yes. Your browser keeps it in local memory until you click Clear, and Yiaho keeps nothing on its side.

Is it suitable for children? The school tools are fine from middle school on. For younger children, Yiaho has an AI for children with a safer frame around it.

Can a teacher tell that AI wrote my homework? Often, yes. Use an AI to understand and to practice, not to hand in a text that is not yours.

Do I need to install anything? No. Every tool on this page opens straight in your browser, on a phone or on a computer, with no account, no download and no credit card.
