A personal Japanese-language shelf of four free Windows tools for downloading, transcribing, editing, and converting video and audio.

Landing page captured for the 2026-09-17 issue.

Field notes

The four applications form a practical local-media workflow: download or import a file, generate subtitles with Whisper, correct timing while listening and viewing waveform or frame information, then convert the result for delivery. The listed subtitle formats include SRT, VTT, ASS, and JSON, while the converter can target a requested file size such as 25 MB. The homepage also records releases and bug fixes across September 9–15, 2026, and links each application to source code.
