Reading Fluency · WCPM

Score oral reading in seconds
— not weeks

Pupils read aloud. AI scores words per minute, accuracy and miscues against the actual passage. An alternative to Amira, Lalilo and MS Reading Progress — built for UK schools.

What makes our scoring different

Word-level transcription, linguistic alignment and private AI feedback

Word-level transcription

We use GPT-4o-mini-transcribe with per-word timestamps — so you can click a miscue and hear the exact moment the pupil read it.

Miscue analysis with Needleman-Wunsch

Classic biological sequence alignment adapted for reading: substitutions, omissions, insertions and self-corrections — separated and scored individually.

Private AI teacher summary

Teachers get an anonymised class overview (Pupil A, Pupil B …) with trends and next steps. No pupil PII leaves the school.

How it works

Step 1

Read aloud

Pupil presses record and reads the assigned passage. Browser microphone — no app needed.

Step 2

We score it

Audio is transcribed with timestamps, aligned to the target text, and scored on WCPM, accuracy and miscues.

Step 3

Teacher & parent see progress

Results are saved in the pupil's portfolio. Teachers see class trends; parents see development over time.
