Our Story

The Problem

Existing English tests take 50+ minutes, cost $65-200, and give vague results. No one knows if they're "low B2" or "almost C1".

The Idea

What if we could use the same IRT algorithms behind GMAT to create a fast, adaptive, AI-powered English diagnostic?

The Build

400 calibrated questions. Adaptive IRT engine. Claude AI integration. Three theme palettes. Share cards. Deep reports.

Today

A platform that tells you your exact English level in 5 minutes — and what to do about it.

How Fluentmood Works

The same science behind GMAT and TOEFL — adapted for fast diagnostics

01
Adaptive Questions

Our IRT engine selects each question based on your current estimated ability. Answer correctly → harder question. Wrong → easier. Every question maximizes information.

02
AI Analysis

After the test, Claude AI reviews every answer — not just what you got wrong, but why. It identifies patterns, gaps, and strengths across grammar, vocabulary, and reading.

03
Precise Results

You get your CEFR level with sub-level precision (“High B1, trending B2”), skill breakdown, confidence score, and a personalized study plan.
