    It first finds lessons that already teach it, and asks a question or two.

  2. The outline AI Tutor plans to write: a title, a goal, five numbered sections and a practice line, above the Build button naming 500 credits

    See the price, then build

    Fixed by length and shown first. The lesson is written live in front of you.

What learning here feels like

A free Git lesson on the platform: the step Commit it, its explanation, and two commands, git commit and git log, each with a Run button and what it printed in the lab's terminal underneath
A free Git lesson on the platform: each Run button types the command into your own lab's terminal and shows what it printed.

Lessons on the platform are hands-on. You run the commands as you read and see the result straight away, on a real machine, with nothing to set up on yours.

  • Run each step from the lesson and see the output
  • Nothing to install: it all runs in your browser
  • Real Linux machines and containers, not a simulation

A lesson AI Tutor builds today is written explanation, callouts and code examples to read, with a lab to practise in where one helps.

What your credits buy

The tutor questions are about that lesson and are answered by the quick tier. The build needs credits you have bought: the free monthly credits do not pay for it.

Why it is different

  • Any subject

    From Linux commands to the history of the printing press. It is not tied to one field.

  • Pay per lesson, no subscription

    From about US$1 for a 30-minute lesson. You pay for what you build and nothing else.

  • Real environments

    Where a lab helps, you practise on a real Linux machine or container in your browser.

  • Yours alone

    Nobody else can open a lesson you build, and you can remove it whenever you like.

  • The price first, and it holds

    You see the price before you press Build, and a build that has begun is finished at that price.

  • Tutor questions included

    Each lesson comes with 30 to 120 questions you can ask the tutor about it.

What AI Tutor is not

  • It is not a person. It is an AI, and it can be wrong, so check what matters.
  • It is not paid for by the free monthly credits. A build is paid from credits you have bought, and you see the price first.
  • A lab is not guaranteed to work. It is written and given a test run, and if it does not pass or cannot be tested you are told and asked before the lesson is added without it.
  • It does not mark your work or replace a course your college sets. It builds a lesson for you to study.
  • The outline preview is the one free part: up to 3 a day, so you can see what it plans to write before you pay.

What to know first

  • AI Tutor is an AI, not a person. It can be wrong, so check what matters.
  • If you are under 18, check with a grown-up before you use it.
  • It builds lessons that teach. It will not write anything harmful, illegal or sexual.
  • Your request and the lesson go to Anthropic, which runs the model, for this feature. The privacy policy has the detail.
  • Nothing installs on your computer.

Questions

What is AI Tutor?

An AI tutor that builds a lesson on the subject you ask for, of the length you choose, and adds it to your lessons. It then answers your questions about the lesson.

What is free for an individual learner?

A free account gives you free lessons and hands-on labs, and free credits every month, enough to follow most lessons. A VM or container to practise in runs on those credits. AI Tutor builds are paid from credits you have bought.

How much does a lesson cost?

500 credits for 30 minutes, 1,000 for 1 hour and 2,000 for 2 hours, which is about US$1, US$2 and US$4. You see the price before anything starts.

What happens when I run out of credits?

For labs, VMs and apps, your use is counted and shown, and for now nothing is stopped. An AI Tutor build needs enough bought credits for its price: if you do not have them, nothing is taken and nothing is built.

Do credits expire?

Free credits arrive each month and unused ones do not carry over. Bought credits stay valid for 12 months.

Does it build a lab to practise in?

Where one would help, yes: a virtual machine or a container lab is written for the lesson and given a test run. If the lab does not pass its test, or cannot be tested, AI Tutor says so and asks you before it adds the lesson without it.

Is there a free preview?

Yes, of the outline only. You can ask for an outline preview up to 3 times a day: a title, a goal and the sections it plans to write. The build itself costs credits you have bought.

Can anyone else see my lesson?

No. A lesson is only yours, and nobody else can open it.

Can I ask questions about the lesson?

Yes. Each lesson comes with tutor questions about it: 30 for 30 minutes, 60 for 1 hour and 120 for 2 hours.

Is it a person?

No, it is an AI. It can make mistakes, so check anything important.
