Sherlen & LangSolution AI
The new TOEFL exam is here.
And Writing is where
students lose their score.
The TOEFL changed in January 2026 — new format, new tasks, new rules. Most students are walking into the exam unprepared for what Writing now demands. Sherlen built this package specifically for the new exam, so you don't find out the hard way.
Real coaching.
No live classes to schedule
The TOEFL launched a new format in January 2026. The Writing section now looks different — the tasks have changed, the expectations have shifted, and the old ways of preparing simply don't work anymore. Students who show up without knowing the new format are losing points they didn't have to lose.
Writing is the skill that comes up again and again — the emails, the Academic Discussion questions, the sentence-level mistakes that keep pulling scores down. Students know they need work on it. But live coaching spots are limited, and not everyone can afford a full package right now.
So Sherlen created something in between — a 2-week guided Writing program inside LangSolution AI, where the platform teaches you using her exact methods, and she still shows up personally to review your work. No live sessions needed. No waiting for a calendar slot. Just real progress, on your schedule.
The AI practices with you.
Sherlen never leaves the room.
Most platforms give you tools and disappear. This is different. You work on LangSolution AI and get instant, detailed feedback every step of the way — but Sherlen is always in the background, watching your progress, stepping in personally, and making sure you're never stuck alone.
AI feedback — instantly
This is not generic AI. Every piece of feedback comes from a system trained on Sherlen's exact teaching methodology — the same approach she has used with 5,000+ students across 55+ countries. It thinks the way she thinks. It catches what she catches. And it tells you exactly what to fix and why, the moment you submit.
Sherlen monitors your progress
She watches how you're doing — your scores, your patterns, your improvement. You are not a anonymous user on a platform. You are her student, and she pays attention.
Personal video from Sherlen
She reviews your actual responses and records a personal video going through your work — what's strong, what needs fixing, and exactly what to do next. This is the human layer no platform can replicate.
Ask her anything — anytime
Have a question about your feedback? Not sure why your score didn't go up? Ask Sherlen directly on the platform and get a real answer. You are never left wondering alone.
"You get the speed of AI and the judgment of a teacher who has spent 20 years figuring out exactly why students don't improve — and what actually fixes it."
— Sherlen, Founder · LangSolution AI
Why this is different from every other platform out there
LingoLeap, Magoosh, TestGlider, MyBestTest, TestSucceed — they're all built by engineers. This was built by a teacher, for a very specific student.
AI without a teacher
- ❌ Generic AI trained on mass data with no teaching philosophy behind it
- ❌ Scores your writing but can't tell you why you keep making the same mistakes
- ❌ No human ever looks at your work
- ❌ Built for the average student — not for a pharmacist, dentist, or nurse with a licensing deadline
- ❌ Cheap but generic — built for everyone, which means built for no one
AI + the teacher who built it
- ✅ AI trained on Sherlen's exact methodology — the same system that has helped 5,000+ students in 55+ countries
- ✅ Feedback that teaches, not just scores — you understand what to fix and exactly how
- ✅ Sherlen personally reviews your writing and sends you a video feedback
- ✅ Designed specifically for healthcare professionals who need real results, fast
- ✅ One clear price, two focused weeks, zero confusion

Sherlen reviews your writing personally and sends you a recorded video with specific, actionable guidance.
Instant Ideas — Writing Tasks
Stuck on what to write? Every Academic Discussion question comes with an Instant Ideas prompt — a quick set of direction starters to get your thinking moving before time runs out. Not a model answer. Not a script. Just enough to spark the idea so the words come from you. This is how you train real writing fluency — by practicing it, not avoiding it.
TOEFL Email Writing.
It has rules nobody taught you.
Which one sounds like you?
You speak well. You read well. You understand everything — but your Writing score won't move past a 3 or 3.5 and you have no idea why.
Your English still needs work — and on top of that, you're trying to figure out a scoring system nobody ever explained to you. You're fighting two battles at once.
The new TOEFL Email Writing section rewards a very specific kind of response.
Specific organization. Specific detail. Specific format. If nobody taught you what that looks like, your score stays flat — no matter how strong your English actually is.
I built a system that handles both situations — whether you have strong English and just need the formula, or you're still building your language skills alongside learning how to score.
"Structure → Detail → Score.
That's how it works. That's what I train."
— Sherlen, Founder · LangSolution AI
Practice the way you need — then prove you're ready.
Most platforms give you one mode and call it preparation. LangSolution AI gives you two — because learning and testing are not the same thing.
The progression is intentional. You train in Training Mode until the structure feels automatic — then you step into Exam Mode and find out your real score. That's not just practice. That's preparation.
Instant feedback so detailed,
you'll know exactly what to fix.
Other platforms give you a score and move on. LangSolution AI gives you feedback that reads like a teacher sat down and went through your response line by line.
Same student. Same response. Two completely different experiences.
Try the same question up to 4 times.
Watch your ETS score climb with each attempt. That's not just practice — that's how real improvement happens.
Every attempt is scored using the official ETS Writing Rubric — the same standard ETS uses on test day. You don't just feel like you're improving. You see it, scored, in black and white.
Your response and your improved response — side by side.
You don't just read the feedback. You see exactly what changed, what was wrong, and what the improved version looks like — all in one place.
- •The response lacks directness — the main point about agreeing with Sophia appears in the middle of the response rather than at the beginning.
- •The opening presents a vague, non-committal position ("many strategies") before eventually choosing a side.
- •The "I would add that" contribution merely restates that internships lead to jobs, which is already Sophia's point, rather than adding something new.
- •The example about a university course is underdeveloped and lacks specific details.
- •Opens directly with clear agreement with Sophia, establishing the position immediately.
- •The "I would add that" section introduces a genuinely NEW contribution — professional networking — that extends beyond Sophia's point.
- •Includes a specific, detailed example with concrete details (cousin, engineering internship, six months, supervisor, three job offers).
- •Maintains clear focus on one main idea throughout the response.
Every time you submit a response, LangSolution AI shows you both versions together so you can see the exact difference — not just read about it.
You're not just buying a platform.
You're getting a teacher.
The AI does the daily heavy lifting. Sherlen brings the human judgment that no algorithm can replace.
I built this platform because I watched thousands of students waste months on tools that couldn't actually teach them. The AI on this platform thinks the way I think — because I trained it. But I also show up personally, because some things still need a human eye.
I am an experienced linguistics specialist, accent coach, and exam tutor dedicated to helping non-native speakers communicate clearly and confidently in English.
