What Fluen AI Subtitle Generator is
Fluen AI Subtitle Generator turns uploaded audio and video into timed subtitles, with an editor for adjusting captions and exports for subtitle files or captioned video. It accepts formats including MP4, MOV, MKV, AVI, MP3, WAV, M4A, and FLAC. Editing tools include timeline adjustments, speaker labels, filler-word removal, and custom glossaries; detected speakers can also be renamed or reassigned. Fluen translates captions into more than 50 languages with context-aware formatting, and offers batch processing, shared project workspaces, a REST API, outbound webhooks, and Zapier connections to more than 9,000 apps. Exports include SRT, WebVTT, TTML, SBV, ITT, EBU STL, SSA, plain text, and burned-in MP4. The free plan covers up to three files, each no longer than 90 minutes, and does not require a credit card, but exporting requires a paid plan. Premium costs $259.00 per year; Team costs $499.00 per year. Media retention is 30 days on Free, 90 days on Premium, and 180 days on Team.
