For independent language tutors

Level-calibrated AI for independent language tutors

Clairoom writes material at the CEFR level you ask for, corrects homework and remembers each student's recurring mistakes. You review and approve every step.

Every exercise at the level you asked for

General AI drifts away from the level you ask for. Clairoom measures every text it generates against the CEFR level you chose and rewrites what falls outside it, before you see it.

  2. MeasureEvery word and structure checked against that level.
  3. CorrectAnything above it is rewritten. You approve the result.

Researchbehind every check

Built on a research programme with measurable targets

Three questions decide whether AI helps a language tutor or misleads them. Clairoom works on each one with a measurable target.

Workstream 1
80% exact 95% ±1

CEFR calibration

Generated material at the requested level, in English and French. Targets on tutor-rated tests: 80% exact, 95% within one level.

Workstream 2

Learner error model

Predicts which errors a student will repeat, from their history and first language. Dashed rings mark the predicted repeats.

Workstream 3
com·FOR·ta·ble stress moved: hard to understand

Intelligibility

Pronunciation feedback on what makes a learner hard to understand. A foreign accent on its own is not flagged.
