In their own words
CaptionRoom
CaptionRoom is a browser-based video editor with AI captions and a timeline editor. Its editing tools include cuts, picture-in-picture layers, text and image overlays, audio tracks, and colour effects. The free plan supports manual captions in two styles, exports up to 1080p with SRT files, and adds no watermark. Captions can be burned into video, and brand caption presets are available. Pro adds AI captions that transcribe and time words in 99+ languages, an editable transcript, karaoke-style captions, AI Clips, translation, filler-word cleanup, and generated titles, descriptions, and hashtags. Pro exports up to 4K. Free accounts can earn AI credits by watching short ads, and AI jobs use credits. Video files, projects, edits, and exports stay on the user’s device; extracted audio is sent for transcription and, the page says, is not retained afterward. Caption text for Pro translation, cleanup, and title or hashtag tools goes to CaptionRoom’s servers. The editor runs in supported browsers on Windows, Mac, and Linux without installation. Pro is $12 a month billed annually; monthly billing is $20 a month.
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.
