The examiner, simulated.
BandBoost grades full-length IELTS mock tests across all four skills — against the exact band descriptors examiners use — and tells you the score you'd get today, criterion by criterion.
Grades like an examiner.
Explains like a tutor.
BandBoost runs full, timed mock tests, then evaluates every response against the official nine-band descriptors — the same criteria a certified examiner applies. You get a band per skill, the breakdown behind it, and the precise moves that lift it.
Intelligence, built for assessment.
A purpose-built evaluation stack — not a general chatbot in a costume. Every capability is anchored to the rubric.
Tested like an instrument.
Scoring you can trust is scoring you can measure. Every model release runs the same loop, against held-out responses a certified examiner has already marked.
We build evaluation intelligence — and we started with the hardest rubric in language testing.
BandBoost reads an IELTS response the way a certified examiner does: criterion by criterion, against the published descriptors — never by vibes. It is the first instrument out of the lab, and the method generalises far beyond it.
asmṛti — Sanskrit: that which is remembered, recorded with precision.
Every score traces back to a published band descriptor. No mystery numbers.
We publish agreement, error and drift — and re-run them on every release.
Certified markers sit in the loop, from calibration through to review.
