QUICK ANSWERStart with the tool that matches your immediate input.
Open Captions Checklist Generator first when its stated purpose matches the result you need now. Use Keyboard Focus Checklist only when it solves a separate next task.
This guide is for designers, developers, editors, and site owners. Start with Captions Checklist Generator when your immediate task is to check common captions checklist issues and receive practical improvement guidance. Move to Keyboard Focus Checklist only when you also need to check common keyboard focus checklist issues and receive practical improvement guidance.
The goal is not to run two tools automatically. It is to finish the first narrow task, inspect its result, and then decide whether Keyboard Focus Checklist solves a genuinely different next step.
Both tools sit in Accessibility Tools, but they handle different inputs or outcomes. Keeping those roles separate reduces repeated work and makes verification easier.
