Mastering English

English that holds up in the room

A personal platform built around your recurring mistakes, your professional goals, and clear General American pronunciation — with Persian explanations wherever they help.

It learns your mistakes

Every error you make while speaking or writing is stored, categorized, explained in both languages, and turned into practice built from your own sentences.

Fifteen skills, measured separately

Reading at B2 and spontaneous speaking at B1 is normal. One overall level would hide the thing you most need to fix.

Production, not recognition

Words move through eight stages from "seen it" to "used it in a meeting". Only the last one counts.

The situations you are afraid of

Phone calls with no visual support. Meetings with interruptions. Investor questions you did not expect.

What this does not promise

No app can make you indistinguishable from a native speaker, and this one will not claim to. What it can do is take you from intermediate to highly fluent, accurate and professionally effective English with clear General American pronunciation — by measuring where you actually are, and working on what is actually wrong.
