The assignment
Build an app that makes you learn AI concepts the Duolingo way. Wire it up with PostHog for analytics.
No accessible submission found for this quest.
No public artifact was shared for Juhi's Quest 5, so there is nothing here to assess honestly — and inventing an opinion about a build nobody can open would be worth less than saying so. What the quest asked for is below; it is worth reading if you are attempting it yourself.
Retention is a design problem, not a content problem. Wiring PostHog in from day one is the tell of a builder who ships to learn from real behaviour — rather than to admire their own screenshot.
A loop worth coming back to
Bite-sized lessons, instant feedback, and a reason to return tomorrow — streaks, XP, spaced review. A long article with a quiz at the end is not the Duolingo shape.
Concepts that are worth the streak
Tokens, embeddings, attention, hallucination, RAG — the vocabulary a PM needs in a real conversation, not 'what is AI' trivia.
Instrumented, not just launched
PostHog wired in and firing real events. An analytics claim nobody can verify tells a reader nothing about how the product is used.
No numeric scores are published here. These pages are written reads of what each builder shipped — the build is the point, not a mark out of a hundred.
