Questions

The awkward ones, answered first

If an answer here would embarrass us, it is still here. A curation product that cannot survive its own FAQ is not worth ₹5,000$59 of anyone’s money.

  • Nothing stops you watching all of them for free, and we would rather say that here than have you work it out later. Each lesson links straight to the creator's own upload - we do not re-host, re-cut or run ads against anybody's teaching.

    What you are buying is everything around the video: which 588 survived out of a much larger candidate list, which of the 102 channels is allowed to teach a given idea at all, what order the 416 lessons go in so that lesson 34 only assumes lessons 1 to 33, the written notes that carry what the video skipped, and a checkpoint at the end of each module that tells you whether it landed.

  • Free, permanently, with no account: the full curriculum for every track, each lesson page, the outcome and prerequisites for each lesson, all the curated videos, and the opening paragraph of the notes.

    Gated behind the one-time payment: the rest of the written notes, and the module checkpoints with their answer keys.

  • A working software engineer with no machine-learning background - someone who can ship production code and read a stack trace, but could not explain what an embedding is if a colleague asked at lunch.

    It is not a maths refresher and not a research-paper club. It runs from no ML at all to a retrieval-augmented application you have deployed and can defend in a design review, and then it stops.

  • No. The whole curriculum is built on the assumption that you have a laptop and free tiers, and nothing else. Any lesson that could only be done with paid infrastructure was cut rather than fudged.

  • No. It is one payment for one track, and the access does not expire. There is no renewal date and no per-seat charge.

    Klay Coach - the separate aptitude tutor for entrance exams - is the monthly product. The two are billed and sold independently; buying one never quietly signs you up for the other.

  • The syllabus is finished and public: 8 modules, 94 lessons, every one of them with its notes already written. What is still running is the video curation - matching each of those lessons to the best explanation that exists and gating the result. 93 have one so far, and the lesson page says which. The other four tracks are finished on both counts.

    Curation is ordered so that the earliest modules complete first. A half-built track is a shippable early half, never a scatter of holes.

  • Every shipped lesson is re-validated on a schedule. If a video is removed, made private, region-locked, or its channel comes off the allowlist, the lesson is rebuilt - usually from an alternate that was already stored alongside it when the lesson was first built.

    A dead embed is a bug in the product, not an inconvenience you are expected to route around.
