Blumify
Blumify converts recordings into text and performs the everyday audio and video file jobs that normally need desktop software.
Paste a YouTube, Spotify or Apple Podcasts link and Blumify returns the full timestamped transcript with a summary, key points, chapters and question answers drawn from the transcript itself. Each result becomes a public page at a stable URL, with timestamp deep links and .txt, .md, .srt and .vtt exports.
Alongside the transcript tool there are more than thirty free single-purpose tools for files: transcribe audio to text, generate SRT and VTT subtitles, compress or convert video, trim, resize, rotate, flip, crop, mute, change speed, reverse, extract a frame or the audio track, convert between MP4, WebM, MOV, MP3, WAV and M4A, and turn video into GIF or a GIF back into video.
