321 Downloader by 321 BRO

321 Downloader helps you detect and save accessible media from supported websites.

Saved media can be opened in 321 Player for local playback or in 321 Scripter to create timestamped transcripts using the AI speech-recognition engine bundled with the extension. Speech recognition runs locally on your device; audio and transcripts are not uploaded for transcription.

Features include media detection and saving, local media playback, local AI transcription, TXT/SRT transcript export, and download history.

Availability of media depends on the website and the media accessible to the user. 321 Downloader does not provide access to DRM-protected, paywalled, or otherwise inaccessible content.
