30 seconds, with sound. Spellio on a MacBook, in Mail and Messages.

The copy-paste dance

Every email. Every message. Every post.

Asking an AI chat to fix one sentence means leaving what you're writing, twice. Spellio brings the fix to your text instead.

With Spellio

1 step

Press ⌘⇧Space, or press firmly on your trackpad.

The fix appears in place, in the app you're already using. Nothing to copy, nowhere to switch to.

Try it right here

One shortcut. Or one firm press.

Hi Sarah,
I beleive we can definately ship the new featur by tommorow.

Press ⌘⇧Space.

Select your text and press the shortcut. Spellio rewrites it in place, in the app you're using. Prefer another combination? Record your own in Settings.

Try it: press ⌘⇧Space now, or tap the keys.

Or press firmly.

On a Force Touch trackpad, one firm press does the same thing. During setup, Spellio learns how hard you press, so light clicks stay clicks.

Try it: press and hold the trackpad.

Questions

Good to know.

Which Macs does Spellio run on?

Any Mac running macOS 15 Sequoia or later. On-device models need Apple silicon. The cloud model works on every supported Mac.

Do I need a Force Touch trackpad?

No. The keyboard shortcut, ⌘⇧Space by default, works on every Mac. A firm press on a Force Touch trackpad is a second way to trigger the same fix.

Which apps does it work in?

Any app where you can select text: Mail, Messages, Notes, Slack, Safari, Chrome, your editor. Spellio reads the selection and writes the correction back in place.

Is my writing private?

With an on-device model, every word stays on your Mac. With the cloud model, the selected text is sent to Gemini 2.5 Flash through OpenRouter, using your own API key.

Why does Spellio ask for Accessibility access?

So it can read your selection and write the correction back. macOS asks you once, under System Settings › Privacy & Security › Accessibility.

How does the license work?

You pay once and get a lifetime key, usable on up to 3 Macs at a time. To move it to another Mac, deactivate it under Settings › License. Every purchase comes with a 7-day money-back guarantee.

I lost my license key.

Enter the email you used at checkout on the key recovery page and we'll send it again.

Your next typo is one press away.
