Frequently asked questions
Is Sentence Counter free to use?
Yes. Sentence Counter is completely free with no account, no trial and no usage cap. Every feature on this page is available on the first visit.
Does Sentence Counter upload your file to a server?
No. Sentence Counter processes your file inside your browser, so it never reaches a DocTools server. That also means the tool keeps working if your connection drops mid-task.
Is there a limit on how much input I can use?
Sentence Counter handles inputs into the megabytes without trouble; the only real limit is how much your browser tab can hold in memory.
Do I need to install anything to use Sentence Counter?
No installation is needed. Sentence Counter runs in Chrome, Edge, Firefox and Safari, on desktop and on mobile, with no extension or plugin.
Can I use Sentence Counter on a phone or tablet?
Yes. The Sentence Counter interface adapts to small screens and supports touch input, though very large jobs are faster on a desktop browser.
What happens to your file when I close the tab?
It is discarded. Sentence Counter keeps everything in temporary browser memory, so closing the tab removes every trace of the session.
