Polish transcription that keeps the endings.
Polish is a genuine test of a transcription engine, and the gap between the good ones and the rest is wider than the marketing suggests. Here is where we land, measured.

How Canto handles this language
Polish inflects heavily, so the ending of a word carries the grammar and an engine that hears the stem but guesses the ending produces text that is subtly wrong throughout rather than obviously wrong in one place. Consonant clusters and the ś/sz, ć/cz distinctions are the other common failure point. Canto is scored on the same public benchmark as every other language listed here.
What the benchmark measures
Word error rate counts every insertion, deletion and substitution against a human reference transcript, then divides by the number of words spoken. Lower is better, and 5% means roughly one wrong word in twenty. We measure on FLEURS, a public benchmark of read speech across many languages, so anyone can repeat the test rather than take our word for it.
How we measure
The same audio goes through both engines with no per-language tuning, and the output is scored with the same normalisation on both sides. We publish the competing engine's figure alongside ours rather than only our own, because a number with nothing to compare it to says very little.

Questions
How accurate is Polish transcription?
Canto measures 2.3% word error rate on the public FLEURS benchmark, against 5.9% for the engine most other notetakers build on.
Does it handle mixed Polish and English?
Yes. Detection is automatic and works mid-sentence, which matters in meetings where technical vocabulary stays in English.
Can I get summaries and notes in Polish?
Yes. The interface and all AI-written output are available in Polish.
