About this app

■ Usage Guidelines

· The "Precise Lecture Transcript" mode requires an additional model download (approx. 190MB). A Wi-Fi environment is recommended.

· Daily conversion time is limited during the free trial period; you can extend this time by watching rewarded advertisements.

· Due to the limitations of the STT engine, conversion results may not be 100% accurate. Please review important records before use.
