Learn anything, at your own pace. With a tutor that answers at midnight.

1. Step 1

   Start from the subject

   Name what you want to learn, or hand over what you are already working through: the textbook, the syllabus, the manual, the pile of papers. There is no blank page and no course to shop for.

2. Step 2

   Say where you are

   What you already know, how deep you want to go — a taster, a proper course, or something thorough — and how it should explain things. Every step is a choice from a short list.

3. Step 3

   Work through it

   The course opens as short lessons with a quiz at the end of each, a level at a time, and it keeps your place — so you can stop mid-level on Tuesday and pick it up on Sunday. Ask the tutor anything as you go.

• Your Own Course

  Name a subject and get back a course built for where you actually are: short lessons and quizzes, a level at a time, going as deep as you asked. It keeps your place, so the gap between sessions costs you nothing.

• Tutor for Your Textbook

  Hand it the textbook, the lecture notes, the papers. Ask what you did not follow and get the answer with the passage it came from quoted — so you end up back in the book rather than trusting a paraphrase.

• Explain This

  Dense material in, the parts that matter out, at the length you asked for. The chapter before the seminar, the paper before the reading group, the standard before you have to work to it.

• Look It Up Properly

  Ask the question you would otherwise lose an evening to and get a briefing with its sources attached: what was found, where each part came from, and what the material does not settle.

• Read It in Your Language

  Move a source into your language, or your notes into the one you are learning, at the register you chose — with names, figures and structure left where they were.

• Read It Back

  The last read before you hand something in or send it. Mistakes only, a light tidy, or a proper sharpening — you decide how far it may go, so it stays your writing.

• Anything else that helps you learn

  Describe it in your own words and build the app for it. Flashcards from a chapter, a question bank to test yourself against, a glossary of every term in the module, a plan for the six weeks before an exam — if you can say what goes in and what should come out, it can be built.

• Each stays good at one thing

  Your course keeps the level it is pitched at. Your textbook app keeps the textbook. Neither has to become a worse version of the other to cover both, which is why the answers stay sharp.

• Nobody else is in the room

  Your books, your notes and your questions stay in your workspace. Nothing is shared with anybody unless you deliberately share it, and asking the same thing four times is between you and the app.

• You can see where an answer came from

  Answers from your material quote the passage, and anything looked up on the web arrives with the page, the publisher and the date. Which is what lets you learn from it rather than just believe it.

  First example. You decide to learn statistics from a low base. Your Own Course, built from the Private Tutor recipe, works alone and hands back a course pitched at a beginner: short lessons with a quiz at the end of each, level by level, keeping your place as you go.

  One app, two minutes to build, and the first lesson opens tonight. Your place is kept, so a busy week costs you nothing.

  Second example. A textbook chapter has not made sense after three attempts. Explain This, built from the Summarizer recipe, consults Tutor for Your Textbook, built from the Chat with Documents recipe, on what the chapter actually says and where. It then explains the same idea another way, quoting the paragraph it came from.

  A second explanation you can check against the first. Nothing was invented to make it easier to follow.

  Third example. You have six months to become employable in a new field, with two books and no map. Your Own Course, built from the Private Tutor recipe, consults three apps in turn: Look It Up Properly, on what the field expects somebody to know and who says so; Tutor for Your Textbook, on how much of that the two books already cover; and Explain This, on getting four papers down to what a beginner needs. It then builds a six-month course from the books you own, naming its sources. Each app was called directly, and none of them called any further.

  A study plan you can check, built from what you already have — and every claim about the field naming where it came from.

What exactly does a course look like?

Short lessons grouped into levels, with a quiz at the end of each, built from the subject or the material you gave it. You choose how deep it goes — a taster, a proper course, or something thorough — and what you already know, so it starts where you are. It opens in the browser and keeps your place, so stopping halfway through a level costs you nothing.

Can it work from the books and notes I already have?

Yes, and it is usually the better version. Upload the textbook, the lecture notes, the papers or the manual and the app answers from those, quoting the passage each answer came from. It reads PDFs, Word, Excel, PowerPoint, and plain text, Markdown, CSV and JSON. Files are read in your browser, so the original never leaves your computer.

How do I know it is not teaching me something wrong?

Because it shows its working. Answers from your own material quote the passage they came from, so you can check them against the book you are holding, and anything looked up on the web arrives with the page, the publisher and the date. Where sources disagree, it says so rather than picking one. It is a tutor to argue with, not an oracle.

Will it prepare me for a specific exam or certification?

It will build a course from a syllabus you give it, and answer questions from the official material you upload — which is genuinely useful. What it is not is affiliated with any awarding body, and it holds no accreditation: nothing here is an official preparation course, and no result inside it counts for anything outside it.

Does anyone else see what I ask it?

No. Your material, your apps and your questions stay in your workspace and are visible to you unless you deliberately share an app. Answering a question means sending the relevant passages to the AI model provider that answers it; nothing is sold or shared with anyone else.

Can I learn a language with it?

Partly, and it is worth being straight about which part. It will build a course, explain grammar from your own textbook, and move text between languages at the register you choose — so reading, vocabulary and comprehension are well served. What it does not do is hold a spoken conversation with you or mark your pronunciation.

How much does it cost?

Individual is $29 a month, which is one account for one person and everything on this page. Before that there is a free trial: 5 apps for 3 days, no credit card — enough to build the course on the subject you have been meaning to start and find out whether you keep going.

Do I need to know anything technical?

No. You say what you want to learn and answer a few questions, each one a choice from a short list. We choose the AI model, write the instructions and handle the rest underneath. There is nothing to code, nothing to configure and nothing to install.
