First impressions
People are already feeling the difference.
Messages shared by early users.
It’s so refreshing to finally find something that tells you to rely less on AI. Truly relieving to know there’s a chance for me to upgrade my English with your help.
I’ve tried your app and it’s excellent. I love it so much, and it’s genuinely helpful for non-native speakers. Thank you for building this.

FAQ
A few things you might be wondering.
Is this another grammar checker like Grammarly?
No.
26Keys does everything you'd expect from a grammar checker and also helps you improve your English over time.
The goal isn't just better messages today. It's helping you become a better communicator.
Why pay for this when ChatGPT is free?
Because they do different jobs.
ChatGPT writes for you. 26Keys makes you a better writer.
Does 26Keys work inside Gmail, Slack, or WhatsApp?
26Keys is its own window, not a plugin.
Write and proofread in 26Keys, then send from Gmail, Slack, WhatsApp, or anywhere else. Nothing to install in your other apps. Only the window you write in changes.
What happens when 26Keys checks my writing?
Your writing is processed only for the moment you check it. It is never stored on our servers or used to train AI.
That's why you can use 26Keys for real work messages, including sensitive ones.
Who is 26Keys made for?
Anyone who uses English every day and wants to actually get better at it.
You don't need to be a professional writer, and you don't need extra practice time. 26Keys works with what you already write, from quick messages and work emails to academic writing.
It's not only for beginners: it reads your level and adapts, so whether you're intermediate or advanced, there's always a next step.
Can I prompt it to rewrite my text in different styles?
No.
26Keys doesn't rewrite your text to sound more professional, friendly, or AI-polished.
It only makes the changes needed to improve your English while preserving your original voice.
The goal is not to write better sentences for you. The goal is to help you learn to write them yourself.
How much does 26Keys cost?
One plan, with two billing options:
- $124.99/year with a 14-day free trial
- $14.99/month with a 3-day free trial
Both include every feature and are Mac App Store subscriptions tied to your Apple account.
Cancel anytime in your App Store settings, and your subscription restores automatically when you sign in on a new Mac.
Your writing and progress stay on your Mac, with optional iCloud sync to keep them across your Macs.
What do I need to run 26Keys?
A Mac running macOS 26 or later.
26Keys is a native macOS app, downloaded from the Mac App Store. No account needed to start your trial.
