Nerdsip
A single developer can build a useful minimal replacement covering on-demand course generation, quizzes, media and a swipe UI, but reproducing NerdSip's nightly quality-scoring, in-house ranking at scale, polished native apps and staffed moderation would be expensive and operationally heavy — so keep paying for full product unless you only need a narrow workflow.

No open-source build does this yet
Nothing published replaces this one, so a replacement starts from an empty file. Here is what it would have to cover.
What a replacement has to do
- User requests a topic → backend calls LLM + web search grounding to synthesize a 7-lesson micro-course → generate multiple-choice questions and explanations per lesson → produce an infographic and an audio version → store course and user progress; present via swipe deck with basic gamification (XP, streaks).
What it still won’t have
- Polished native iOS and Android apps and store presence
- The in-house large-scale ranking engine and trending social signals
- Nightly automated quality scoring and a staffed human moderation queue
- Mature content/seed library and brand trust
- Scale-tested multiplayer features (leaderboards, leagues, friend feed)
What remains hard
- Product polish and ongoing maintenance

Runnable build prompt
Build a minimal AI microlearning web app using Node.js + Express, Postgres, React Native (or Expo) for mobile, OpenAI-compatible LLM API, a web-search retrieval step (SerpAPI or Bing Search API), an image-generation API (e.g., Midjourney/Stable Diffusion API) and a TTS service. Core features in scope: (1) endpoint to accept a topic and depth and produce a 7-lesson course (lesson text, one MCQ+explanation each) by combining retrieved search snippets with LLM prompts; (2) store courses, sources, and user progress in Postgres; (3) generate and attach one infographic image and one audio file per course via external APIs; (4) a swipe-deck UI to browse suggested courses and a course reader with quizzes; (5) simple gamification (XP, streak counter) and a report button that creates a moderation queue item. Out of scope: social feed/leaderboards at scale, nightly global quality scoring pipeline, paid-subscription billing UI, heavy ranking-engine personalization, and staffed moderation workflows. Include API error handling, input validation, basic unit tests for generation and storage logic, and README with deployment steps and environment variable examples.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
