The client speaks
Convert parents with a diagnostic, then deliver a real expert.
Gapzen wanted a standalone web app able to convert parents through a simple, engaging “Free” diagnostic, then deliver in Premium a genuine AI Expert built on a massive document base.
All of it had to embed a clear freemium model, a smooth experience and ready-to-use monetisation.
The context
A consumer product, for the first time as demanding on UX as on AI.
1 product · target French-speaking parents
The Free journey — 10 questions, that's it.
A 10-question AI quiz, with semantic analysis of the answers. The user arrives, answers, immediately sees a first analysis. No friction, no hidden paywall.
By the end of the diagnostic, the Premium value becomes obvious — not sold, demonstrated.
The Free tier
The Premium tier — 14,754 pages indexed in RAG.
On the Premium side, a RAG AI agent drawing on 14,754 pages, indexed by theme, with a dedicated OCR pipeline to also exploit images.
Every agent answer cites its sources — reliability comes before fluency.
The document base
indexed by theme, exploited in RAG.
Stripe, partner codes, and a sovereign stack.
Premium access can be unlocked via Stripe or partner codes — to grant access to partner schools or organisations without friction.
Authentication, freemium management and payment form a robust foundation, ready to scale.
