Tap any feature to see how it works

Feature 1 / 10 · Speaking tutor

An examiner in every learner’s pocket.

Learners speak, and within seconds get sentence-level corrections, a pronunciation heatmap, fluency metrics and a band estimate scored against the official rubric.

Feedback streams in while the learner is still talking.

Six speech engines

Routed per surface for the best accuracy and latency.

Band estimates

IELTS, TOEFL and PTE rubrics, applied consistently.

Five exam graders plus general and business writing — rubric scores, sentence-by-sentence rewrites, improvement priorities and a top-band model answer.

Two-tier grading

A cheap pass on every submission, deep analysis on demand.

Model rewrites

Learners see exactly what band 9 looks like for their own text.

One video, five completely different workouts.

Mining deck

Sentences learners save become review material.

One queue

Six content types reviewed in a single daily session.

Generated practice

Exercises, audio and podcasts built per card.

Compounding value

The longer a learner stays, the harder it is to leave.

Full mock exams

Four skills, real timings, scored automatically.

A full task set from one lesson topic.

Automatic grading

Teachers review instead of marking.

Guardian reporting

Weekly progress digests, sent automatically.
