Hi, I'm Hammy. I live in your menu bar.
Works in Chrome, Safari, Slack, Mail, Notes, Messages, Notion and the rest of your Mac apps. Fixes spelling, grammar, punctuation and tone.
How it works on Mac
Hammy hangs out in your menu bar and reads along while you write. Nothing in your text changes until you fix it.
-
Type
Write like normal, in any app. A tiny Hammy sits at the end of the field you're typing in.
-
Pause
He underlines each typo and shows a count. Take a breath and a review card pops up: Fix, Skip or Fix all.
-
Fixed
Click, or keep your hands on the keys: ⌃⌥⏎ fixes, ⌃⌥⌫ skips and ⌃⌥→ hops to the next one.
Your words
Send guard
Catch typos before you hit send.
Turn on “Catch typos before I send” and Hammy holds the send key while typos are still open. Fix & send, send anyway or keep editing.

Mac FAQ
Questions? Hammy's got answers.
Does it work in Chrome, Safari and Slack?
Yes. InkHammy uses macOS Accessibility to see the text near your cursor, so it works in the apps you already use: Chrome, Safari, Slack, Mail, Notes, Messages and more. There's no browser extension to install.
What permissions does it need?
Accessibility, so Hammy can read and update the text field you're typing in. You allow it once in System Settings → Privacy & Security → Accessibility. The microphone is only used while you dictate. Passwords and secure fields are never collected.
Is InkHammy free?
Yes, free to start. Sign in and Hammy checks everything you write, shows every suggestion, and fixes 5 typos and rewrites 3 messages a day on the house. Hammy Pro makes fixes, rewrites, tones and translation unlimited for $9.99 a week or $99.99 a year (that's $1.92 a week). This download checks out securely on the web with Stripe. The Mac App Store edition subscribes through the App Store instead.
Which macOS version do I need?
macOS 14 Sonoma or later. Hammy needs an internet connection for AI fixes.
Does it change my text without asking?
No. Hammy only underlines and suggests. Nothing in your text changes until you choose Fix or Fix all. Hover an underline to preview a fix first, or hold ⌥ in the review card to see why he flagged it.
Is there an iPhone version?
Yes. InkHammy for iPhone comes with a Hammy keyboard and a paste-and-fix app. Get it free on the App Store or see Hammy on iPhone. Sign in with the same account and Pro works on both.
