Fluen AI Subtitle Generator
Fluen AI Subtitle Generator turns uploaded audio and video into timed subtitles, with an editor for refining captions and exports for subtitle files or captioned video. Inputs include 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 be renamed or reassigned. Fluen translates captions into more than 50 languages with context-aware formatting and language-specific re-segmentation. Export formats include SRT, WebVTT, TTML, SBV, ITT, EBU STL, SSA, plain text and burned-in MP4. Batch processing, shared project workspaces, a REST API, outbound webhooks and Zapier connections to more than 9,000 apps are also listed. The free plan allows three files of up to 90 minutes each and does not require a card, but exporting requires a paid plan. Free translations are limited to three languages per file and show only the first 15 minutes. Premium costs $259 a year; Team costs $499 a year. Media retention is 30 days for Free, 90 days for Premium and 180 days for Team.
