Study a topic end to end

Open any topic and choose Lesson. Pick a depth, then move through the scenes. Each factual scene shows the exact claim it came from, and the primary-visual scene links to the Canvas and Visual Studio.

Open Flashcards. Reveal each answer, check its evidence, and rate your recall. The local spaced-repetition schedule decides what returns and when — nothing is written to a server.

Open Quiz. Every option is a real concept from the revision, so wrong answers are plausible but honest. Your best score stays on the device. Export any artefact as a revision-pinned snapshot with attribution.
