Compare Claude, Perplexity, Gemini and ChatGPT to support autobiographical writing in 3rd

Use described publicly by Café pédagogique — Claire Ridel, enseignante (collège Henri Matisse) (8 December 2025), summarised by the desk. Not tested by iadujour.

The result to aim for

Claire Ridel, professor at Henri Matisse College in Grand-Couronne, tested four IAGs to write instructions, lexical banks, primers and assessment grids written autobiographically in 3rd — an usage designed for teachers of letters.

What was done

Educational Café (Jean-Michel Le Baut, December 8, 2025). Writing book: autobiographical pact inspired by Rousseau, self-portrait Leiris way, place of childhood in the way of Amélie Nothomb. Reason: "the quick of vocabulary "K0 Series of prompts reproduced (consign, support, lexical bank, primers, skills, 4-stage grid). Examples: classified lexicon (identity, memory, uncertainty) and paragraph primers. Balance sheet: answers of "unequal quality, sometimes fruitful", useful especially for clear instructions, beginnings and vocabulary. Vigilance quoted: "some AIs do not reply to the prompt, others do too much"; lacunae text "leaves too little room for personal expression". Consignee: "don't use them as they are" and ask "what will be useful in building the skills of my students."No copy rates or timing are published.

Your starting point.

Replace the bracketed items, then adapt the proposal to your situation. This prompt is written by the iadujour desk It is not a quotation from the source.

The prompt to customise
Writing objective (without student name): autobiographical pact in 3rd. Extract from support text: [coller].

Provides a statement, 12 lexical bank words, 5 primers, and a 4-step grid. Report what would be too guided.

What deserves your attention

Do not paste registered copies into a general public account. A generated primer is not the text of the student: select, adapt, and do not replace the writing with too little guided text.
