AI tutor for programming
Get up to speed on a new framework or codebase, with a 1-on-1 AI tutor
Turn docs, videos and code repositories into a guided path to real mastery. Sitor finds what you already know, teaches by asking instead of handing you answers, and has you practice until you can use it in your own project.
Docs, tutorials and chatbots stop at "I think I get it"
Tutorials don't know what you know
You sit through the basics you already use and skim past the one concept you're actually missing.
Chatbots hand you the answer
Code that runs isn't code you understand. Next week you're pasting the same question again.
A new codebase has no map
Where to start, which modules matter, which patterns it assumes you know: nobody wrote that down.
How Sitor works
Step 1
Diagnose what you already know
Tell Sitor what you need to learn and what you already work with. A few quick diagnostic questions find your gaps, so you skip what you know.
Step 2
Get a path built from your materials
Point it at the official docs, a PDF, a YouTube talk or a GitHub repository. Sitor reads them and lays out a roadmap of concepts in the order you need them.
Step 3
Practice until it's mastered
Each concept is taught by questions: you predict, explain and apply it to a new case. The next step unlocks only when you've earned it.
Real Sitor screens. Example topics; yours will be built from your goal and materials.
What you can bring
- Docs and web pages
- Public GitHub repositories
- Code as a .zip archive
- YouTube talks and tutorials
- PDF, EPUB, Word, Markdown
- Screenshots and diagrams
What you get
Learn from the real code
Import a repository and browse its files next to the lesson; explanations point at the files they're about.
One goal, many sessions
Your roadmap and progress stay with the topic, so you pick up where you left off instead of re-explaining.
Run code while you learn
On Pro, a code sandbox in the desktop web app lets you edit and run examples without leaving the lesson.
Review before it fades
Spaced review brings concepts back on the forgetting curve, as short retrieval conversations.
How mastery is scored
Each concept is scored on four criteria before it counts as mastered and the next one unlocks:
- Accurate
- your answer is correct
- Explained
- you can say why, not just what
- Novel application
- you can use it on a case you haven't seen
- Discrimination
- you can tell it apart from similar ideas

Questions
Isn't this just ChatGPT with a different look?
No. A chatbot answers what you ask. Sitor starts by diagnosing what you know, keeps one learning goal across sessions, builds a roadmap, and won't mark a concept as mastered until you've explained it and applied it to a new case.
Can it teach me a codebase, not just a framework?
Yes. Import a public GitHub repository by its URL, or upload the code as a .zip archive. Sitor reads the files and teaches from them: what the main modules do, how a request flows through, which patterns the code relies on.
Which languages and frameworks does it cover?
Any you can point it at. It works best when you bring the material you'd otherwise read alone: the official docs, a book, a conference talk or the source code itself.
Do I need to install anything?
No. Sitor runs in the browser. An optional browser extension saves any web page as learning material in one click.
How much does it cost?
The free plan includes 50 credits a month and up to 10 learning topics. Starter is $9.9/month and Pro is $19.9/month, and the first month of either is discounted. You can cancel any time.
