What it teaches

The mistakes non-native speakers make most in work English (an advice, explain me, discuss about, suggest me to, look forward to meet, since three years, said me, lend/borrow, do/make), then polite requests (could you, would you mind + -ing, I would be grateful if), formal greetings and endings, and finally whole work emails: chasing an invoice, asking for more time, declining a meeting, introducing yourself. The AI asks 3 questions, places you, shows a short card per module, then gives you one sentence or email at a time and checks it against the rules, naming the exact mistake.

How long

34 items. About 20-45 rounds (about 20 if you already know the basics, 45 from scratch) plus a 10-item final: 2-3 sessions (estimate, not timed with a real student). The tutor gives a one-line save code at the end of each session.

Before it teaches, it asks

1
What do you write in English at work (emails to clients, to your team, reports, chat)? What’s your first language? What worries you most: grammar mistakes, sounding rude, or sounding too stiff?
AI voice (ElevenLabs)
2
Correct this sentence: “Can you explain me the numbers?”
3
Make this polite (to a shop or hotel): “I want to speak to your manager.”

What’s exact, and what isn’t

Show

Straight from the course’s own notes.

Sourced: Every grammar rule comes from Cambridge Dictionary’s English Grammar Today (13 entries); several wrong sentences are Cambridge’s own “Not:” examples set at work. 45 short quotes matched word for word on the live pages on 2026-10-10.
Checked by script: Every wrong sentence is caught by the course’s list of mistakes, and no answer or model email is; every polite-request answer uses a polite form. The check is a rough net (it misses some mistakes and flags some correct sentences), so the tutor grades by the rules, not the script.
Judged, not computed: Whether another correct version counts, and whether an email covers each required point. The tutor grades by the item’s Rule and the checklist, and accepts a correct version that isn’t in the key.
Honest limit: Text only. No pronunciation or speaking practice.
Not in it yet: Tenses, articles (a/the), prepositions of time and place beyond for/since, meetings and phone English, report writing.
