QUICK ANSWERStart with the tool that matches your immediate input.
Open Reading Time Calculator first when its stated purpose matches the result you need now. Use Remove Duplicate Lines only when it solves a separate next task.
This guide is for writers, students, marketers, and teams. Start with Reading Time Calculator when your immediate task is to open the original Reading Time Calculator and complete the task with a focused browser-based interface. Move to Remove Duplicate Lines only when you also need to open the original Remove Duplicate Lines and complete the task with a focused browser-based interface.
The goal is not to run two tools automatically. It is to finish the first narrow task, inspect its result, and then decide whether Remove Duplicate Lines solves a genuinely different next step.
Both tools sit in AI & Writing, but they handle different inputs or outcomes. Keeping those roles separate reduces repeated work and makes verification easier.
