How it works

You Write — Your voice stays yours. No rewrite.
We Teach — We turn your mistakes into lessons.
You Grow — You say it right. In the actual meeting.

The English you write becomes the English you speak.

The problem isn't your English.

It's that no method actually
taught you what matters.

✕Language apps teach generic content. Not what you struggle with.

✕Courses demand extra hours you don't have.

✕Textbooks teach grammar rules. Not how to use them at work.

✓26Keys learns from your real writing so you practice what truly matters to you.

What early users say

"I used to paste every email into ChatGPT. Now I actually understand why my sentence was wrong. Huge difference."

P

Priya S.

"The 'why it matters' explanations are what make this different. I've stopped making the same preposition mistakes I made for 10 years."

K

Kenji T.

Software Engineer, Tokyo

"I finally feel confident writing to my American clients without rereading everything three times. It's like having a patient teacher built into my workflow."

Hi Sarah, I wanted to discuss about the quarterly report. The numbers looks promising and I think we should present it to the leadership team next week.

Ambiguity Check

Make sure the reader understands exactly what you mean

Sometimes your sentence is correct but easy to misread. 26Keys spots those moments and shows you a clearer way to say it. You pick what to change. Nothing changes without you.

"I think we should present them to the leadership team next week"

Ambiguity detected

"Next week" could mean different days to different people. Consider specifying: "by Friday, March 21" or "during Monday's standup."

Quick Review

One rule. One minute. One real improvement.

After each write, 26Keys picks the one error that matters most and helps you understand it. So your next message is already better than this one.

Why this matters

"Discuss" is a transitive verb. It takes a direct object. You don't need "about" after it. Think of it like "enter" vs "enter into." This is one of the most common patterns non-native speakers mix up.

Writing Patterns

Your mistakes become your curriculum

Every correction feeds into your personal writing patterns. Your daily practice, just 2 minutes, generated purely based on this. No generic lessons. Real improvement you can feel.

26Keys is made for you.

It learns how you write from day one and builds practice that is truly yours. Beginner or advanced, you improve every day.

Why writing?

You already practice English 50 times a day at work.

26Keys turns the writing you already do into learning. No extra study time. No courses to schedule.

No extra time needed

You already write 40+ emails a week. Each one is a lesson waiting to happen. Zero extra study hours.

Low pressure, deep learning

Unlike speaking, you can pause, rethink, and fix before anyone sees. That's the environment where real learning sticks.

Your speaking improves too

When you stop writing "looking forward to hear from you," you stop saying it too. Cleaner grammar in writing rewires how you speak in meetings.

Progress you can actually see

Your error patterns shrink week over week. Not a feeling. Your dashboard shows it. Real, measurable improvement.

"Think of writing as slow speaking."

The preposition you understand in an email today won't trip you up in tomorrow's presentation.

Fix mistakes in writing. It fixes itself in speaking.

Frequently asked questions

Everything you need to know before getting started.

Most grammar tools show you what's wrong. You hit accept, move on, and make the same mistake tomorrow. ChatGPT goes further and rewrites for you. Your message sounds perfect, but you slowly lose your own voice.

26Keys is different. First thing, your voice stays yours. No rewrite. It learns your writing patterns, turns your repeated mistakes into practice, and helps you break them. Not because a tool caught them, but because you understood why they were wrong.
