How to Find the Right Tool
Start by identifying the category that matches your task — for example, PDF Tools for document work, AI Tools for writing and content, or Developer Tools for code utilities. Each category page lists every active tool in that group along with a short description, so you can scan and pick the right one in seconds.
If you already know the tool's name, the search bar on the homepage is the fastest route. If you're exploring or comparing options, browsing by category gives you the full picture of what's available for that type of task.
