- ◆Ask it to think through a problem before answering ("reason step by step, then give your recommendation") for noticeably better analysis.

06 Frequently Asked Questions
How is Claude different from ChatGPT?
Both are top-tier general assistants. Claude is often preferred for long documents, careful nuanced writing, and coding, while ChatGPT has a broader consumer feature set (image generation, voice mode, plugins). Many professionals use both and pick per task.
Is Claude free to use?
Yes — claude.ai has a free tier with daily usage limits. Paid plans raise the limits, add the most capable models, and unlock features like Projects for persistent context.
Can Claude write and debug code?
Yes, coding is one of Claude's strongest areas — it can write, explain, review, and debug code across most languages, and its long context window lets it work with large files.
