Prilo AI
A competent developer can build a useful subset (question serving, LLM feedback, progress tracking) in ~38 hours and run it for modest monthly costs; there are no durable moats shown on the site that prevent DIY.

No pricing page we fetched carried a figure, so there is nothing to compare against. The build side is still real.

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 Prilo AI alternatives, with the arithmetic →
What a replacement has to do
- Students practice competition-style questions, get AI feedback/explanations, and track progress over time.
What it still won’t have
- Curated proprietary question bank and any licensing/partnership content
- Polished UX, branding and marketing that attract users
- Managed customer support and account services
- Any community or network effects from an existing user base
- Enterprise integrations or compliance assurances (if present)
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 minimal AI study platform using Next.js (React), Node/Express, PostgreSQL, Tailwind CSS, and the OpenAI API. In scope: user auth (email/password), admin CSV import for question sets, question browse/playview, submit answer flow that calls an LLM to provide an explanation/feedback, store attempts and simple progress metrics, basic analytics dashboard for a single user, CI tests for core routes, and Docker-based deployment. Out of scope: mobile native apps, multi-tenant billing, advanced analytics pipelines, and proprietary question-licensing workflows. Include error handling, retries for API calls, and unit/integration tests for critical paths.
How we checked
How the score was reached
- Build verdict base78
- An open-source build was found+5
- 3 cited sources+3
- Evidence score86
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.
