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.
