We help you be understood, not just correct.
ei5 exists for everyone working to communicate in English: students, professionals, and teams who want their spoken English to actually reach the people they are talking to.
English is for being understood, not for passing tests.
Most English study in Japan is optimized for a score. You memorize vocabulary, drill grammar, and sit a paper test. But none of that tells you whether a native speaker can actually follow what you are saying.
ei5 was built to close that gap. What we focus on is communication itself: the ability to speak with native English speakers and be understood clearly, in real conversations.
Vocabulary and grammar matter, but they are only the foundation. What we care about is whether your message gets through.
The goal isn't a higher score. It's being understood.
From a native ear.How your English sounds, from a native perspective.
When you speak English, there is a gap between what you mean to say and what actually reaches the listener. ei5 measures that gap the way a native speaker hears it.
Heard, not graded on paper
We assess the speech itself: your rhythm, your clarity, and how naturally it flows to a native listener.
The listener's perspective
Our evaluation reflects how your English comes across to the person in front of you, not just whether it is technically correct.
Concrete, not abstract
Instead of a single number, you see exactly where your message gets through and where it gets lost.
The principles behind everything we build.
Communication first
We start from a simple question: did the listener understand you? Everything we measure ladders up to that.
Honest about how you sound
Even when it differs from how it feels to speak, we tell you how your English actually lands.
Improvement you can see
Progress should be visible. Every result points to specific things you can work on next.
