Prompts IA sélectionnés pour des usages professionnels, créatifs et techniques.
Works well with any current-generation reasoning model — GPT-5.4, Claude Sonnet 5, and Gemini 3 Pro all handle multi-step analogical mapping accurately. Weaker or older models tend to stop at a single anchor analogy and skip the mapping table or the "where it breaks" section unless explicitly prompted to continue through the full structure.learningA product manager with eight years running retail store operations is joining a database architecture review next week and needs to actually understand how sharding works — not just nod along — because she's grown up in grocery logistics, not distributed systems, and generic explainer articles keep losing her at the third paragraph.
Un prompt structuré qui associe chaque mécanisme de fonctionnement d'un concept inconnu à son équivalent direct dans un domaine que vous connaissez déjà en profondeur, avec une liste explicite des points où l'analogie s'effondre.

Works well with GPT-5.4 and Claude Sonnet 5 — both handle platform-specific character constraints and distinct psychological framing reliably. Gemini 3 Pro produces strong copy but occasionally runs over stated character limits, so budget a quick manual trim pass if you use it.marketingYou're the performance marketing manager at a 15-person direct-to-consumer skincare startup. Your CEO wants a paid campaign live on Meta and Google Search by tomorrow morning for a new $42 vitamin C serum, with a $5,000 weekly test budget approved. Marketing is a two-person team, nobody has bandwidth tonight to brainstorm five genuinely distinct ad angles from scratch, and the launch date isn't moving.
Un prompt structure qui prend un seul brief produit et renvoie cinq variantes de publicites veritablement differentes selon des angles psychologiques distincts, chacune associee a une hypothese de test A/B plutot que simplement cinq versions de la meme idee.

Works well with any current-generation model — GPT-5.4, Claude Sonnet 5, and Gemini 3 Pro all handle spreadsheet formula logic and edge-case reasoning accurately. Smaller or older models occasionally suggest deprecated functions (like legacy array-entry CSE formulas) or mix Excel and Google Sheets syntax, so it's worth double-checking the output against the tool you specified.Analyse de DonnéesYou're a sales operations analyst at a mid-size SaaS company, working in a Google Sheets pipeline tracker with roughly 3,000 rows. Finance needs the weighted average discount percentage across all deals marked "Closed Won" in Q3, weighted by deal value, and a few rows have a blank discount field because a rep forgot to fill it in. The number is due in the quarterly business review deck in two hours, and you need a formula that handles the blanks correctly instead of silently including them as zero and skewing the average down.
Un prompt structure qui prend un calcul decrit en langage courant et renvoie une formule Excel ou Google Sheets prete a copier-coller, avec une explication etape par etape de son fonctionnement et de ce qui pourrait la casser.

Claude Opus 5 (also works well with GPT-5.4 and Gemini 3 Pro)CarrièreYou have a final-round interview in three days for a senior product manager role, and you know behavioral questions are coming, but your work history spans five different projects and you're not sure which stories map to which likely questions — or where your prep has gaps.
Un prompt en trois passes qui prédit les questions comportementales qu'un poste posera, les associe à votre véritable parcours professionnel, et rédige des réponses au format STAR — tout en signalant les lacunes où vous n'avez pas encore d'histoire solide.

Claude Opus 5 (also works well with GPT-5.4 and Gemini 3 Pro)Outils de DéveloppementYou just merged a pull request that adds a new POST /api/v1/refunds endpoint to your team's billing service. The endpoint works, tests pass, but nobody wrote documentation — and your team lead just asked you to get docs into the developer portal before external partners can start calling it next week. You have the code in front of you and forty-five minutes before your next meeting.
Un prompt en deux passes qui lit le code de votre endpoint, extrait le contrat réel, et rédige une documentation de référence qui signale l'ambiguïté au lieu de deviner — conçu pour combler l'écart entre « le code fonctionne » et « la documentation est en ligne ».

Claude Opus 5 (also works well with GPT-5.4 and Gemini 3 Pro)Rédaction et CommunicationYou have a 47-page customer research report due to the CEO before Monday's board meeting, and you know from experience that a report this long simply won't get read before the meeting starts. You need the actual findings — the numbers, the causal story, the recommendation — condensed into something a time-pressed executive will read in the elevator on the way to the boardroom.
Un prompt structuré qui compresse de longs rapports en une synthèse exécutive d'une seule page avec des conclusions traçables, des implications claires, et des actions recommandées spécifiques — conçu pour survivre à une lecture rapide de cinq minutes par quelqu'un qui ne lira pas au-delà de la page deux.

Claude Opus 5 (also works well with GPT-5.4 and Gemini 3 Pro)Finance et NégociationYou've received a written job offer with a base salary $8,000 below what levels.fyi and three Glassdoor data points show is market rate for the role. You have one week before you need to confirm your start date, and your current employer hasn't offered to match. You know you should negotiate, but you're not sure what number to counter with, how to justify it without sounding entitled, or what to say if the recruiter pushes back with "this is our best offer."
Un prompt structuré qui transforme vos recherches sur la rémunération et vos offres concurrentes en un script de négociation complet, avec des chiffres d'ancrage, des réponses aux objections et un seuil de rupture que vous avez réellement calculé plutôt que deviné.

Claude Opus 5 (also works well with GPT-5.4 and Gemini 3 Pro)Startups et EntreprisesA product marketing lead is refreshing messaging ahead of a Q3 rebrand and needs to know, with evidence, which competitive claims actually hold up before locking in a new tagline.
Un prompt qui met à l'épreuve votre positionnement produit face à de vrais concurrents et signale toute affirmation que vous ne pouvez pas réellement défendre.
prompt-engineeringmarketing
Works well with GPT-5, Claude Sonnet 5, or Gemini 3 Pro — this is primarily a pattern-recognition and arithmetic task, so mid-tier reasoning models handle it reliably. Larger models add value mainly in phrasing the bias explanation clearly.productivityA freelance web developer has blown three consecutive project deadlines, each time because "one more round of client revisions" ran long, and has a new project proposal due tomorrow where the client is specifically asking for a firm time-and-cost estimate broken down by task.
Un prompt IA qui exploite votre propre historique de temps estimés par rapport aux temps réels pour calculer une correction de biais spécifique à chaque catégorie, afin que votre prochain devis soit calibré plutôt que deviné.

Works best with Claude Opus or GPT-5 for nuanced persona consistency across multiple rounds. Gemini 3 Pro is a solid alternative; smaller models tend to let personas agree too easily instead of staying skeptical.marketingA B2B SaaS marketing lead has a positioning statement drafted for next month's product launch and an exec review meeting in two days, but has a nagging feeling the current wording is generic enough that it would not survive a real skeptical buyer conversation — and there is no time to run a proper customer discovery session before the deadline.
Un jeu de rôle IA en trois manches qui confronte votre positionnement à un champion sceptique, un acheteur économique et un CFO — avant qu’un vrai prospect ne le voie.

Works best with Claude Sonnet 5 or GPT-5.4 — both reliably apply named statistical concepts (Simpson's paradox, survivorship bias) to a specific dataset rather than listing them generically. Gemini 3 Pro is a solid alternative when the pasted dashboard data is very long.Analyse de DonnéesYou're a growth PM about to tell the exec team that a redesigned onboarding flow increased 30-day retention by 12%, based on a dashboard comparing users who completed the new flow against users who went through the old one last quarter — and you have a strategy meeting in an hour where this number will justify rolling the flow out to 100% of new signups.
Un prompt qui passe en revue toute métrique ou dashboard pour détecter les illusions statistiques qui font passer les mauvaises décisions pour des décisions fondées sur les données — biais de survie, paradoxe de Simpson, plages de dates sélectionnées à la convenance — avant d'entrer dans la salle et d'engager votre crédibilité sur le chiffre.
