About
FreeSubtitles AI is a web-based transcription and subtitle generation tool that makes it easy to convert audio and video content into accurate text — completely free. Powered by AI, it supports a wide range of file formats including MP4, MKV, MOV, MP3, WAV, and FLAC, and can auto-detect the spoken language from a pool of 100 supported languages. In addition to transcription, the platform offers built-in translation into 91 languages, making it an ideal solution for content creators, educators, and businesses working with multilingual audiences. The free tier allows files up to 1 hour in length and 300 MB in size, while a Pro plan unlocks additional credits and advanced features. Users simply drag and drop their file, select the source language (or enable auto-detection), optionally choose a target translation language, and receive a transcript ready for download or further editing. A developer API is also available for teams looking to integrate transcription capabilities into their own workflows and applications. FreeSubtitles AI is particularly useful for YouTubers and video creators who need subtitles fast, journalists and researchers transcribing interviews, and global businesses localizing video content. Its straightforward interface requires no account to get started, making it one of the most accessible AI transcription tools available online.
