"AI" piano transcriber, same level of performance with most of the online paid versions, only with Transparency (as you know what's going on (usually under the hood)), Safety (nothing is uploaded or stored, your data is completely local!), and Fast (thus no backend bottlenecking). Thanks to the opensource Bytedance/Kongqiuqiang et al. piano transcription model! trained on MAESTRO plus other cool datasets, ykyk, as good as it gets... (P.S. right now this webpage is tested only on Chrome, performance not guaranteed on other browsers like safari)
