For coding, my pick is Claude, with ChatGPT as the runner-up. This recommendation focuses on understanding existing projects and making changes you can review.
Try Claude ↗Prompting tip for Claude
Talk to Claude like you’re talking to a coworker. Keep your prompt simple and include context: what you’re working on, what you need, and what a good result looks like.
Why this pick & when to choose the alternative
Why choose Claude?
Start with Claude when the job needs context from several files, a clear explanation of a bug, or a plan for changing an existing project. For repository-level work, Claude Code is a separate coding workflow; a chat window and a coding agent do not have identical capabilities.
When to choose ChatGPT instead
Choose ChatGPT instead for a focused debugging conversation, a small script, or an explanation of code you can paste into the chat. Say which environment and tools you are using before asking for a fix.
What to check before relying on the answer
Generated code can look correct and still fail, introduce security problems, or use outdated APIs. Review the diff and run the relevant checks before shipping.
A starter prompt for Claude
Help me fix [problem] in this [language/framework] project. Expected behavior: [expected]. Actual behavior: [actual]. Relevant code and error: [paste]. Explain the likely cause and propose the smallest change.
Questions about coding
Do I need Claude Code to ask coding questions?
No. You can discuss code in Claude chat. Claude Code is a coding agent for working with a repository and running development tasks; check its access requirements separately.
What context should I include when asking for debugging help?
Include the exact error, relevant code, framework version, expected behavior, and what you already tried. Remove secrets before sharing logs or files.
