Layout Autocorrection FREE

Three levels of control over your keyboard layout:

Automatic correction — MonKey detects the wrong layout as you type and instantly fixes the text with no action required on your part
Hotkey correction — typed a word in the wrong language? Press a hotkey and the text is replaced without deleting and retyping
Selected text correction — select any block of text and force-convert it to the correct layout

Works with English, Ukrainian, German, Spanish, Polish and Hebrew. More languages coming with future updates.

Translation FREEPRO

Translate selected text between 55+ languages with cloud AI. Free: 2 translations/day. PRO: unlimited. No internet — automatic fallback to Apple Translation.

Grammar & Style FREEPRO

Spot grammar, punctuation and style errors with LanguageTool + AI — 3x more accurate. Free: 2 checks/day. PRO: unlimited. No internet — automatic fallback to macOS spellcheck.

AI Wizard PRO

Select text, press Option+W — done. 5 categories of tools:

AI actions — tone, simplify, summarize, expand, custom prompt
Case transforms — UPPER, lower, Title Case, tOGGLE
Transliteration — Cyrillic ↔ Latin
Developer tools — camelCase ↔ snake_case ↔ kebab-case ↔ PascalCase, URL encode/decode
List operations — sort A→Z / Z→A, remove duplicates, add line numbers

Just type

MonKey lives in your menu bar and quietly monitors your keyboard. It detects layout mismatches in real time as you type.

Select text

For translation, grammar or AI actions — select the text you need. Layout autocorrection doesn't need selection — MonKey remembers what you just typed.

Press a hotkey

One hotkey — done. MonKey fixes your layout, translates or checks grammar instantly. The more you use it, the smarter it gets.

Private by Default

Your keystrokes never leave your Mac. Translation and grammar use cloud AI only when you trigger them — and only send the text you explicitly select. No internet? Automatic offline fallback.

Context-Aware

MonKey tracks sentence context and learns from your corrections. The more you use it, the smarter it gets — fewer unnecessary fixes, more accurate layout detection.

Your Data Stays Yours

MonKey reads your keyboard to fix layout errors — not to spy on you.
Here's how we keep your data safe.

No Keystroke Logging

Keystrokes are processed in memory and immediately discarded. Nothing is written to disk in release builds.

Offline Fallback Built In

No internet? MonKey automatically switches to on-device Apple Translation and macOS spellcheck. Your workflow never stops.

Zero Telemetry

No analytics, no tracking, no crash reporting. We have no way of knowing how you use the app.

Cloud Is Opt-In

Premium AI features only send text you explicitly select. No background data collection, ever.

App Store Reviewed

Every update is reviewed by Apple before release. The app runs in a macOS sandbox with minimal permissions.

Verify It Yourself

Use Lulu or Little Snitch to monitor network traffic. Use Objective-See ReiKey to inspect keyboard taps.
