Practical, step-by-step guides that go with our free tools — every step tested, no fluff.
About 2 pages single-spaced, 4 pages double-spaced — but font size and spacing move the answer. The full words-to-pages table, and what else changes the count.

Every ToolRush guide grows out of one of the tools. The tools give you the answer in seconds; the blog walks through the job around it — why the problem happens, the exact steps on each device, and what to try when something does not work the first time. If a guide tells you to tap a button, that button exists in the current app, and the steps are written from the apps as they actually work today.
Start with the tool itself — the Invisible Character page is where the character in the first guide comes from — or browse all 200+ free tools by category. New guides are added here as they are published.
