Gemini Music – Subtitle Downloader

A lightweight Chrome extension for effortless subtitle extraction from AI-generated music

Gemini Music – Subtitle Downloader is a Chrome extension designed to simplify the process of extracting subtitles from AI-generated music inside Google Gemini conversations.

It introduces a seamless one-click .vtt download system, allowing creators to instantly capture lyrics with accurate timestamps—perfect for music production, content creation, and archiving.
