Frequently Asked Questions
Can Toolpilot replace Sublime Text? ▾
Only for isolated text processing tasks. For full code editing with projects, multiple files, and plugins, you still need Sublime Text or VS Code.
Is Toolpilot's regex tester as powerful as Sublime's? ▾
For testing patterns, yes — it shows all matches, capture groups, and supports JavaScript regex syntax. For find-and-replace across files, Sublime Text is more powerful.
Why use Toolpilot instead of my editor for these tasks? ▾
Convenience — no context switching. Open a browser tab, do the task, close it. No need to open a file, switch modes, or interrupt your workflow.
