On my own products, ChatGPT is the first channel that converts.
Ask ChatGPT where to revise for the TAGE MAGE.
It answers Prépa 600, first.
Real capture, 21 September 2026, ahead of ASTPrep, Teachero and FNEGE.
Nothing was asked before: the question is the first message of the conversation.
Services
Two formats, one option. In both: one person to talk to, and a site live within the first days.
Public site, accounts, payments, administration.
A page that presents you and receives enquiries.
Option
Written so ChatGPT cites you.
Every project is different: the price is set after a conversation, never from a catalogue.
Who builds
Founder of AG Algo Lab. I design, code, launch and operate: the same person from the first conversation to the hand-over.
Master's in Finance
Markets, models, data. Hence the habit of measuring before claiming.
Chess
A title from the World Chess Federation. In chess as in code: calculate the lines before you move.
1st place
Two days, satellite data, one challenge: culture at the heart of sustainable cities. First place, among teams gathered on five campuses.
Machine learning
A CatBoost model calibrated on 15,420 car insurance claims. Among the top 0.5% of ranked files, 68.8% are fraud — 11 times the rate in the pile.
Two free courses
Telegram × Python, and CatBoost: two courses, in French, free.
