What CaptionHub is
CaptionHub is an AI-powered collaborative platform for producing multilingual subtitles and voiceover for business use. Its subtitling platform translates and localizes content into 300+ languages, with Natural Captions technology designed to produce natural-sounding captions. Editing tools include frame-accurate and timeline editing, custom dictionaries, speaker-based splitting, hard and soft limits, and collaborative workflows. Teams can export VTT, SRT, STL, TTML, and other subtitle formats, create burnt-in subtitles, or publish directly to online video platforms. CaptionHub Voiceover generates spoken audio using AI voices in different voices, styles, and languages. Studio adds automation across ingest, processing, translation, and publishing, plus API, SDK, webhooks, and web-socket access. Deployment options include cloud, on-premises, hybrid, or VPC environments. The service lists integrations with video, storage, localization, translation, and speech tools including Brightcove, Vimeo, Google Drive, DeepL, OpenAI, and Whisper. Usage is measured in output minutes, deducted when a language version is first downloaded or published; synthetic voice minutes are billed when created. Consumer use is prohibited. Creator & Agency is usage-based at $2.50 a month, while Studio is $1,270 a month and Enterprise is $3,565 a month.
