Learning and careers decision
Tree Nerd Academy
A competent developer can build the platform and AI tutor features (especially using existing open-source projects like studyield), but reproducing the vendor's proprietary videos, the 4,500+ validated question bank, and the pass-guarantee-backed product experience is not realistic without acquiring that content or a large validation effort.

Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All Tree Nerd Academy alternatives, with the arithmetic →
What a replacement has to do
- Watch lesson videos → answer domain-weighted practice questions → use flashcards (spaced repetition) → run timed mock exams → consult AI tutor for explanations and weak-area remediation.
What it still won’t have
- Proprietary instructor video content (high-production lessons)
- The vendor's curated 4,500+ question bank and validated mock-exam corpus
- Pass guarantee and refund policy enforcement
- Lifetime community, career-networking, and podcast content
- Production polish and UX refinements from the commercial product
What remains hard
- Product polish and ongoing maintenance

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a self-hosted ISA exam prep web app using Next.js (React), Postgres, and S3 for video storage; stripe for payments; OpenAI (or compatible) for an Arb AI tutor. Core features: user auth and paid entitlements, video lesson pages with progress tracking, a question-bank-backed quiz engine with per-question explanations, timed 200-question mock exam simulator with domain breakdown, flashcard SRS with review queue and performance tracking, and an LLM-backed tutor endpoint that explains wrong answers and recommends drills. Out of scope: producing instructor-recorded lesson videos and seeding a 4,500-question validated bank (content must be provided separately). Include error handling, input validation, automated tests for API routes and core logic, and deployment scripts (Docker + simple CI).

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.
