Press Tab

Accept one word at a time. Take what you want, then keep typing your own way.

Hand-tuned for the apps
you actually work in.

Built around everyday Mac work apps — email, docs, notes, messages, team chat, and professional web writing. Web app support is focused on Chrome and Safari today, and SpellType also runs alongside most other Mac text fields.

AI that writes with you,
not for you.

We believe in augmenting your writing, not replacing it. SpellType suggests words you'd write anyway — just faster.

The old way

You stop writing. Open a chatbot. Write a prompt. Wait. Get a robotic wall of text. Spend ten minutes editing it to sound like you. Frustrated, you trash it and write the damn thing yourself.

The SpellType way

You never stop typing. The right words just appear — your words, the ones you would have written anyway. Tab. Keep going. What felt like work now feels like flying.

Your words stay yours.

SpellType lives on your Mac and nowhere else. It can't read your writing — and neither can we.

No screenshots. Ever.

Some tools capture your screen to understand context. We don't. SpellType only reads the text field you're actively typing in.

Works offline.

Turn off Wi-Fi. SpellType still works perfectly. One toggle in Settings kills all network calls — analytics, updates, everything.

No account needed.

At launch, the free tier will work without an account. Early access only asks for an email so we can send the Mac build when it is ready.

Smart enough to stay quiet.

SpellType watches your typing speed. When you're in the zone, suggestions pause. When you slow down to think, they appear.

Thinking

Typing slowly? Suggestions appear to help you find the right words.

Cruising

Normal pace. Balanced suggestions when they'd save you time.

In the zone

Typing fast? SpellType goes silent. No interruptions when you're flowing.

Frequently asked questions

Does SpellType work in my app?

Out of the box, SpellType runs in most Mac text fields. The launch app list focuses on Gmail, Outlook, Apple Mail, Google Docs, Microsoft Word, Slack, Teams, Notes, WhatsApp, LinkedIn, ChatGPT, and Messages. Web apps are supported in Chrome and Safari today.

What does it cost?

Free to start with 25 suggestions per day. For unlimited suggestions, Pro is $4.99/month or $39.99/year. No account needed for the free tier.

Why a subscription if it runs locally?

Because making it look simple is the hard part. SpellType works across hundreds of Mac apps — each with its own quirks, text fields, and accessibility behaviors. Apps update, macOS updates, things break. Keeping that compatibility intact, shipping better AI models, and squashing edge cases in apps you've never heard of is constant, full-time work. Your subscription funds that work directly — not servers, not data harvesting. Just one developer making sure it keeps working everywhere.

How is this private if it uses AI?

SpellType runs a small AI model entirely on your Mac's Apple Silicon chip. Your text is processed locally and never transmitted anywhere. One toggle kills all network calls.

What about Grammarly or ChatGPT?

Those tools read your writing and send it to the cloud. SpellType never reads your text — it predicts what comes next based on context, and everything happens on your device.
