If you already use ChatGPT but feel it gives templated answers — it’s time to get acquainted with Claude AI.
Among specialists, analysts, and developers, the opinion is increasingly heard: for serious work with text and documents, Claude surpasses ChatGPT. But is that true? In this article we break it down in detail: what Claude is, what its capabilities are, how much it costs, and when you should choose it.
What Is Claude AI — Explained in Simple Terms
Claude AI is an AI assistant from the company Anthropic, founded in 2021 by former OpenAI employees. The name “Claude” is a tribute to the mathematician Claude Shannon, the father of information theory.
Unlike ChatGPT, Claude was built with a different philosophy: safety and alignment with human values were the top priority from the very beginning. Anthropic developed the method Constitutional AI — training the model on a set of principles similar to a constitution. That’s why Claude is considered one of the safest and most “human” AI assistants.
Today Claude is not just a chatbot. It’s a full-featured tool for deep analytics, writing complex texts, programming, and working with large documents.
Who Created Claude — The Company Anthropic
Anthropic was founded in 2021 by Dario Amodei and Daniela Amodei — brother and sister who previously worked at OpenAI on GPT-3. They left the company over disagreements in their approach to AI safety.
The core idea of Anthropic: AI systems must be reliable, interpretable, and safe. This philosophy permeates every version of Claude.
Today Anthropic is one of the most influential AI companies in the world, having received major investments from Google and Amazon and actively competing with OpenAI for the enterprise AI market.

Key Claude AI Features
Working With Large Documents
This is what truly sets Claude apart from competitors. A context window of up to 200,000 tokens — approximately 150,000 words or an entire book. You can upload a complete technical report, a scientific paper, or several PDFs simultaneously and get a deep analysis.
ChatGPT in its basic version processes a significantly smaller volume per single request.
Text Quality and Naturalness
Many specialists note: Claude’s texts sound more natural. While ChatGPT sometimes gives formal and templated responses, Claude writes in a way that reads like a real person. This is critical for content managers, marketers, and anyone who doesn’t want their texts to look AI-generated.
Programming and Code
In coding tests, Claude Sonnet and Opus consistently score above 90%. The main advantage — code cleanliness and the ability to understand the context of large projects.
The Artifacts feature lets you see the result immediately: write a request — get ready-made code that can be tested directly in the interface. This is especially convenient for no-code development through platforms like Bubble.
Analysis and Research
Claude handles these excellently:
- Comparing and systematizing large volumes of information
- Preparing analytical reports
- Finding patterns in data
- Summarizing meetings and long documents
Safety and Privacy
Anthropic pays special attention to safety. Claude is less prone to “hallucinations” and more clearly marks the boundaries of its knowledge. Constitutional AI makes its behavior predictable and safer for corporate use.
