Claude or ChatGPT: what they do, how they differ, and how to choose.

What we’ll open up.

Claude or ChatGPT: what they do, how they differ, and how to choose. This lesson follows the actual choices behind Tidelight.

Step by step

Remember

An AI helper can chat, and its coding mode can also read and change files and run commands in one folder on your computer.
Claude's coding mode is Claude Code. ChatGPT's is Codex. Tidelight was built with Codex; everything here works the same with Claude Code.
Pick one. You can switch later. The prompts in this course work in both.

Do this now

Choose Claude or ChatGPT, then do the next lesson for the one you chose.
