Products

Three products, built on GitHub

Each one stands on its own. A classroom for schools and universities, and for engineering teams, a review on every pull request and an agent that works in your repos.

Cin90 GitHub Classroom

For schools and universities

Students accept an assignment and get their own repo. Every push is graded, the class page shows what is due next, and daily warm-ups keep the basics fresh.

See the plans
  • Accept and start

    One click makes the repo; the page shows when it is ready.

  • Graded on every push

    Tests run on GitHub and the grade lands on the submission page.

  • Your next step

    Due dates in each student's timezone, outstanding work first.

  • Warm-ups and drills

    Short daily practice, never graded.

Cin90 Review Coming soon

For engineering teams

Every pull request gets a review: what works, what to fix, and why. You set the rules; Review keeps to them.

  • Review on every pull request

    Opened or pushed: comments on the change, against your rules.

  • When CI fails

    What broke, in plain words, and the likely fix.

  • Explain a change

    What a pull request does, in a few lines, for whoever reviews it.

Cin90 Engineer Coming soon

For engineering teams

Your agentic engineering partner. Ask it in chat, mention it in Slack, or put it on a schedule. It works in your repos and asks before it changes anything.

  • "Compare FastAPI and Django for this service"Research

    A short report with its sources, before you decide.
