Why use Claude?
Claude stands out for his ability to reason and to manipulate very large volumes of text in a fluid conversational context. Unlike other models, it has been trained with a strong focus on safety, bias control and reliability.
In a professional context (writing, legal, support, product, etc.), Claude offers significant precision and better alignment with instructions. Its billing model (per entry/exit token) and its variations make its use more predictable for tech or product teams.
How does Claude work?
Claude works on a “Constitutional AI” system: the AI follows a charter of rules and is self-correcting to avoid certain problematic behaviors.
Access can be made via:
- API (key from the Anthropic dashboard)
- Partner interfaces: Notion AI, Poe, Slack, etc.
- Third-party clients (extensions, no-code integrations, custom scripts)
Claude's main features
- Very long multi-contexts : up to 200,000 tokens, ideal for analyzing large documents
- Reliable instruction-following : very good compliance with detailed instructions
- Nuanced answers : fewer hallucinations than its competitors according to several benchmarks
- Fluid “chat” mode : excellent for continuous interactions in a SaaS interface
- Reinforced protection : beware of biases, refusal of certain sensitive requests
Examples of using Claude
- Automatically summarize HR reports or documents in Notion AI
- Feeding a customer support assistant in Slack (internal FAQ + ticket management)
- Analyze a legal or regulatory documentary base in an internal tool
- Generate product sheets from a structured prompt (name, characteristics, advantages)
- Evaluate the quality of web content for SEO or AEO (answer engine optimization)
FAQ: Frequently asked questions about Claude
Is Claude better than ChatGPT?
It depends on the case. Claude is generally more stable, more respectful of instructions, and excellent at long conversations. ChatGPT maintains a slight creative advantage and is more integrated into the OpenAI ecosystem (DALL·E, Code Interpreter...).
Is Claude available for free?
Partially. The API is chargeable. But Claude can be accessed for free via POE.com within certain limits, or integrated into Notion AI (subscription required).
Can Claude be integrated into my internal tools?
Yes, via the Claude API or third-party connectors (n8n, Zapier, Make...). It is used in many professional cases (support, CRM, product...).
Is Claude open source?
No, Claude is a proprietary model developed by Anthropic. On the other hand, its “responsible AI” positioning is documented and transparent.
