This tool is a “professional-grade audio transcription and automated editing pipeline” capable of processing long-form audio data exceeding three hours with extreme stability and without interruption.

It overcomes crashes and timeouts in large files—common issues faced by standard tools—through a proprietary mechanism, and possesses advanced listening capabilities to accurately transcribe “English technical terms” that suddenly mix into natural Japanese conversation.

Furthermore, its greatest feature is the AI cleanup function, which refines the transcribed data like a “professional editor.”

We developed and implemented a unique “Smart Splitting Technology” that analyzes the space-less sentence structure inherent to Japanese and splits the data at safe positions (such as punctuation marks) where the context is not interrupted.

This allows the AI to accurately remove unnecessary fillers (like “um” and “uh”) and insert appropriate punctuation while maintaining the context of long texts.

It is also fully equipped with a fail-safe function that automatically detects and deletes unnecessary files on the cloud to protect the original data, even if unexpected sleep or network disconnections occur during processing.

It is a highly powerful and practical assistant that fully automates the conversion of lengthy podcast or important meeting recordings into “readable and beautiful text” at a level ready to be published as articles or minutes.
