OnVoice: Private Grammar & Spelling Checker

Private grammar and spelling checker that runs on your computer, in every text box you use.

Write with confidence, anywhere you type. OnVoice for Chrome underlines spelling and grammar mistakes as you write and lets you fix them with one click. Email, docs, chat, forms, social posts: if you can type in it, OnVoice can check it. Your writing stays yours. Checks run on your computer, inside the extension. Nothing you type is sent to a server, and there is no account, no analytics and no tracking. What you get - Live underlines and one-click fixes in text boxes across the web - Clear, short explanations for every suggestion - Your own dictionary, and per-site on/off switches - Works offline once installed - Calm and fast: no popups, no nagging Go further with OnVoice for Mac (optional) If you also use the OnVoice app on your Mac, the extension can send the text you select to it, on the same computer, to Fix with OnVoice, or Rewrite with Quill. These actions only run when you click them. Without the Mac app, everything else works as normal. Privacy line: checks happen on your computer. Your writing never leaves it.
