Short answer
Claude is an AI assistant made by Anthropic; ChatGPT is made by OpenAI. Both can answer questions, write content, and help with coding — but they have different personalities, strengths, and safety approaches. Neither is universally better; the right choice depends on what you need.
Who makes them
- ChatGPT — made by OpenAI, founded 2015. Backed by Microsoft. Launched publicly in November 2022.
- Claude — made by Anthropic, founded 2021 by former OpenAI researchers. Backed by Google and Amazon.
Key differences
Writing style
Claude tends to produce more nuanced, careful prose. ChatGPT is often more direct and concise. For long-form writing, many users prefer Claude. For quick factual answers, ChatGPT feels snappier.
Context window
Claude handles longer documents — you can paste an entire book chapter or long contract and ask questions about it. ChatGPT's context window has grown too, but Claude has historically led here.
Safety and refusals
Anthropic built Claude around a concept called "Constitutional AI" — it's trained to be helpful, harmless, and honest. In practice, Claude refuses some requests more cautiously than ChatGPT, which some users find frustrating.
Coding
Both are strong at coding. ChatGPT with Code Interpreter can run code and show results. Claude is often praised for explaining code clearly.
Pricing
Both offer free tiers with usage limits. Paid plans (Claude Pro, ChatGPT Plus) are both ~$20/month and unlock more powerful models.

Frequently Asked Questions
- Is Claude or ChatGPT better?
