Your English has a fingerprint.
Write three sentences about your job. We'll show you your level, the mistakes you repeat, and what you already do well.
This is how you write today.
Your coach remembers this. Every check makes it sharper, and every mistake you stop making gets locked in your vault.
Check what the AI wrote
AI writes smooth English — and sometimes changes what you meant, adds things you never said, or sounds wrong for the situation. Learn to spot it before you send.
Check your writing
Paste an email, a message or a paragraph. Watch it get better, then tap any green word to see why.
Word Vault
Words you're making your own. Use each one in a sentence you write. Get it right 5 times over two weeks and it locks for good.
Paste something AI wrote for you
An email ChatGPT polished, a message Grammarly rewrote. We'll pick the words in it worth owning, so next time you can write them yourself.
Your vault
Each lock is a mistake you've made. Keep it out of 3 checks in a row (30+ words each) and it locks for good.
This week's lesson
Built from the mistake you make most, using your own sentences.
