The SprintBrain extension works in Google Chrome on a computer, and in other browsers that install extensions from the Chrome Web Store.

​
Fields it works in

  • Single-line boxes: text, search, email, web address and phone number fields.
  • Larger text areas.
  • Rich editors, the kind used by email, chat and AI tools, where you can format text.
No setup per site is needed.

​
Where it can’t run

Chrome doesn’t let extensions into some pages: Chrome’s own settings pages, the Chrome Web Store, and PDFs opened in the browser. It also can’t reach apps outside the browser.

​
When typing doesn’t work

If a site blocks typed expansion, you have two ways around it:
  • Right-click menu: right-click in the field and open Insert SprintBrain snippet.
  • The popup: click the SprintBrain icon, open the snippet, fill it in and click Copy filled, then paste.
See Ways to insert.

​
On your phone

The extension doesn’t run on phones. Open app.sprintbrain.com/mobile to search, fill and copy snippets, then paste them into any app. See Mobile.
