View collection →Why collections are different from categories
Categories group similar tools. Collections organize several kinds of tools around a goal. A person preparing a document may need to merge, compress, and convert it; someone checking a paycheck may need time, salary, tax, and planning calculators. These pages show a sensible sequence while still letting you begin at any step.
Private, practical, and free
Whenever technically possible, the tools run in your browser so your files and numbers remain on your device. Read the privacy message on each tool for the exact behavior. No account is required, and the explanations identify important limitations so you can decide when a professional or authoritative source is needed.
