Claude is an AI assistant developed by Anthropic, a company co-founded by former OpenAI researchers. In 2026, Claude Sonnet 4 and Claude Opus 4 are establishing themselves as the benchmarks for complex professional use: long-document analysis, nuanced writing, structured reasoning.
Where ChatGPT has become the consumer tool par excellence, Claude has stood out for demanding enterprise use — and here is why!

5 reasons why companies prefer Claude
1. An exceptionally large context window
Claude can analyse documents of several hundred pages in a single request.
For a legal team working on a 200-page contract, a finance team on an annual report, or HR summarising 500 appraisals, it is an absolute game changer!
2. Precision and reliability on complex tasks
Companies that compare Claude and ChatGPT on reasoning tasks report fewer errors and fewer hallucinations with Claude.
For professional use where errors have real consequences, this is decisive!
3. A tone naturally calibrated for business
Claude produces consistent texts, neither too formal nor too casual, that match business standards.
Less editing, more time for what matters!
4. Stronger data confidentiality
Anthropic offers GDPR-compliant hosting options for European companies, a critical point for legal departments and IT directors...
5. Integration with your existing tools
Claude integrates natively with Slack, Notion, Microsoft 365, and hundreds of tools via Zapier or Make.
Your teams keep their working habits: AI fits into them rather than replacing them.
"We adopted Claude for our marketing briefs and for summarising market research. In 3 weeks, our teams cut the production time of strategic content by 40%."
— B2B Marketing Director, Samsung Enterprise Division
