For long-form writing,
Claude stays ahead.
Style, nuance and calibrated refusals: three months after launch, Opus 4.7 keeps the editorial edge.
Seven days of testing on forty editorial prompts run by SMBs: framing notes, LinkedIn posts, pleadings, creative briefs, client letters. Claude finishes first on 31 of 40 prompts, ahead of ChatGPT and Mistral. The gap is not marketing — you can hear it on a read-through.
« The only one that respects register without slipping into Americanism — first editorial choice, no hesitation. »
« Versatile and fast. A solid second pick if you write short and need to iterate quickly with images. »
« Sovereign, fluid, pleasant to read. Pick it whenever the data must stay in the EU. »
Professional writing demands rare registers — legal, medical, public-sector. English-led benchmarks miss them. Our internal language test puts Claude at 91/100, ahead of Mistral (88) and ChatGPT (84). Not random: Anthropic has invested in non-English post-training since 2024.
An answer engine, not a chatbot. Sources cited by default, clean academic mode — indispensable for monitoring.
2M of real, usable context: Gemini plays in another league for massive document analysis.
Native European hosting, SecNumCloud Enterprise-Sovereign certification: the default pick when the DPO decides.
