Do I need the extension to use the tools?
No. Every tool works in the browser at iotools.cloud/tools, and the site has the same ⌘K search built in. The extension only saves you the trip to the site first — it's for people who reach for these tools often enough that the trip adds up.
What can it see?
Nothing you type into a tool, and nothing on the pages you visit. It doesn't read page content or your browsing history — it opens a popup with a list of tools and navigates to the one you pick. Most tools then run entirely in your browser anyway, so your input never leaves your device.
I use Brave, Arc or Vivaldi.
Install from the Chrome Web Store — those browsers all run Chrome extensions. Edge, Firefox and Opera have their own listings above.
Is there a Safari version?
Not yet. Safari extensions need a separate build and an Apple developer account, so it depends on whether enough people ask. Tell us if you want one— that's genuinely how it gets prioritised.
