In their own words
Checksub
Checksub provides AI-powered subtitles, dubbing, and voice-over for videos through web, API, and extension platforms. It can create subtitles automatically or synchronize subtitles from a script, and it offers subtitle translation in 200 languages. Its dubbing replaces the original voice while keeping the audio background; Checksub also says users can substitute a cloned voice in 30 languages. The online editor lets users revise and regenerate sentences after subtitle or dubbing generation. Subtitles can be burned into exported videos with animated styles, including karaoke animation. Translated-video publishing to YouTube is supported, and the Starter plan connects one channel. Listed integrations include YouTube, Twitch, Google Drive, Adobe Premiere Pro, DaVinci Resolve, and Final Cut Pro. Credit use varies by task: one credit minute per video minute for subtitles, three for dubbing, and five for lip-sync. The service has a free plan and free trial. Checksub was founded in 2017 and is headquartered in France.
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.
