And turns them into learning.
Every mistake you make becomes tomorrow’s lesson, corrected by AI with a teacher’s attention to detail.
“Can you explain me how the new tool works?”
“Can you explain to me how the new tool works?”
With “explain”, use “to” before the person: explain to me.
A quick 5-minute test, or the full test in 15 to 25 minutes.
No card. The first 3 lessons are on us.
Speaking tasks in every lesson, with your pronunciation scored and feedback on what to improve, using the phrases you need at work.
You really write in every lesson and get back the correction of the exact mistake you made, with the reason why and how to improve.
Every mistake is logged and returns in the next lessons, in new examples and exercises, until you really get it right and learn it.
InChek is a course for people who need to really learn, reach real fluency and are tired of little games that teach nothing. Business English, from the most basic level to the most technical.
Every lesson assesses what you actually write and say, and brings your exact mistakes back until they disappear.
You can start learning today, for just $12.42 a month on the annual plan. The placement test is free, takes about 5 minutes (the full test, 15 to 25 minutes, is optional), asks for no card, and the result and the first 3 lessons are yours either way.
You wrote "I’ll send you the report until Friday." One word, and your client now expects reports all week. Here is exactly what comes back, what it costs you, and when you see it again.
A real lesson on near-synonym precision: what this learner got right, and exactly where listening and speaking still slipped.
Find your real level, choose how often, do the work in your browser, get graded and targeted. The email is the doorway, not the classroom.
Free placement test + 3 corrected lessons. No card.
For careers where your communication is judged on a call, in a pitch, or in an email that has to land right the first time.
Context, reading, writing, listening, speaking, vocabulary. Real sources, real transcripts, one spoken task every time.
At your own pace: each level has a quiz every 7 lessons and an exam. (Starting from zero English? A separate ten-level Starter track skips this ladder’s placement test entirely.)
Most courses hand you a syllabus and hope it overlaps with your gaps. InChek starts from the gaps, with a weight on each one.
Not a quiz. A real test, generated for you: about 5 minutes for your starting level. The full test, 15 to 25 minutes, is optional and ends by reading something you wrote and telling you what’s wrong with it.
From $19 a month. Daily grading, every level, exams, and your learning path, on every plan.
Free placement test + 3 corrected lessons. No card.
About fifteen to thirty minutes of real work a lesson, with real writing and speaking in every one. Short enough for a lunch break, real enough to change how you write and speak.
Thirteen questions, answered without hedging. Yes, your pronunciation is scored.
So mistakes made in year one are still being made in year ten. InChek was built for that gap.
Open beta, starting with Business English. The price reflects that, and so does the roughness. Here’s exactly what that means for you.
Use the form below. One to two business days, usually the same day.
The placement test is free and takes about 5 minutes (the full test, 15 to 25 minutes, is optional). No card; your account is created in seconds. You’ll get your level and the first real gaps in your English.
Free placement test + 3 corrected lessons. No card.
