Every change a learner would notice, newest first. Want these in your inbox? The sign-up form at the bottom of the Learn page sends new lessons and videos about twice a month.

  1. Lesson videos, in the founder's voice

    Each published lesson video now sits above its lesson, narrated in the founder's own (cloned) voice and recorded from the live widgets — the same figures you can drag around on the page.

  2. Privacy policy and terms of service

    Plain-English pages on what we store, where it lives, for how long, and the deal for Premium — refunds, cancellation and acceptable use included.

  3. First-visit tour with the Professor

    New here? A short guided tour, narrated by the Professor, walks you through the curriculum, the figures and the labs. Restart it any time from the Learn page.

  4. An honest allowance meter

    The Professor drawer now shows how many messages you have left this month — always on the free tier, and on Premium only when you're running low.

  5. Mobile pass

    Hamburger navigation, a collapsible curriculum, a hero that fits a phone, and no more zoom-jump when you open the Professor on a phone.

  6. The Professor teaches in your language

    Ask in Italian or Romanian (or most other languages) and the Professor answers in kind, keeping the established technical terms in English so they still match the lessons.

  7. The Professor: a personal AI tutor with memory

    Every student gets a tutor that reads over your shoulder, knows which lessons you've visited and how your self-checks went, and remembers how you learn between sessions. Ten messages a month free, a full allowance on Premium.

  8. Launch-readiness ops

    Error alarms on every request-path function, a monthly cost ceiling, and point-in-time recovery on every table that holds your data.

  9. Curriculum errata, second pass

    Sixteen fixes from a full re-audit of every lesson, plus your account chip on every page.

  10. Premium, billing and the account area

    Stripe subscriptions (monthly or annual) unlock the Deep Learning, LLM Engineering and DevOps tracks and every worked solution. A new /account page holds your plan, security settings, progress and the danger zone.

  11. All eight tracks live on the landing page

    Real lesson counts for every track — nothing marked "in development" any more.

  12. Accounts and cross-device progress

    Sign up with an email, and your visited lessons and self-check scores follow you to any device. Delete your account yourself — right now, or scheduled with a 14-day grace period.

  13. 94 lessons live: the curriculum is complete

    The last gap lessons landed with a graded self-check at the end of every module and 443 worked solutions across all nine tracks. A 28-item content audit was fixed the same day.

  14. Experimentation, AI agents and evaluation engineering

    Three lessons that fill the most-asked-for gaps, plus the Foundations mastery layer: 120 worked solutions and four module self-checks.

  15. Full-tree navigation and search

    Every lesson from the sidebar, and a fuzzy search over the whole curriculum (Ctrl K) that ranks titles first.
