SansTypo

The typos nothing else can see.

SansTypo checks what you type in any app, and the words a spell checker can’t reach: text in a slide, a design, a PDF or a screenshot. Point at a mistake and a card offers the fix.

Everything happens on your own computer. Nothing is uploaded, and there is no account.

What it does

As you type

Mistakes get a wavy underline in any app. Point at one and a card offers the fix; one key accepts it.

In pictures

Press the shortcut and drag over text in a design, a slide or a screenshot. SansTypo reads the pixels and marks what it finds.

In the browser

The extension draws marks inside the page, so they scroll with the text, and tidies vague prompts in AI chat boxes.

The browser extension

For Chrome and Firefox. Both stores have it and are reviewing it; until a store lists it, the app tells you where things stand.

Your words stay yours

SansTypo has no server. The app checks your text on your own machine, and the extension hands text only to the app on your computer, over a connection that cannot leave it. Password fields are never read. Read the privacy policy.

Support

Found something broken, or something that reads wrong? Open an issue and say what you saw. Include your system and, if the app misbehaved, its log file — the app’s About screen says where that is.
