How Hosiqo compares and tests toolsFinal recommendation
Shortlist CaptionKit when providing live captions for deaf and hard-of-hearing attendees during services or events matters most, and SyncWords when delivering accessible, fcc-compliant live captions for a broadcast matters most. Run both through a week of actual calls to see which suits your workflow.

Live AI captioning, subtitling, and voice-dubbing platform for webinars, streams, and hybrid events with real-time multilingual output.
CaptionKit is a browser-based platform that produces live, AI-generated captions and translations during spoken sessions, designed primarily for churches and other faith-based organizations serving deaf, hard-of-hearing, and multilingual audiences. A host starts a captioning session from the web dashboard, and the system transcribes speech in 65+ languages and translates it into 85+ languages, including a bilingual English and Spanish mode. Attendees follow along by joining a shared web link or QR code, or through the free iOS and Android apps; captions can also be displayed on screen as lower-third overlays or full-screen scrolling text. It integrates with common presentation and streaming software including ProPresenter, OBS, vMix, FreeShow, and Worship Extreme, and supports automation via cURL and Bitfocus Companion. Accuracy can be improved with boosted keywords for names and uncommon terms, and the platform records session history. No installation is required, making it suited to live in-person or streamed events where on-screen accessibility and language access matter.

SyncWords is an AI-powered platform for delivering live and recorded video content to multilingual audiences through real-time captions, subtitles, and voice dubbing. For live scenarios, it produces frame-accurate AI captions that meet broadcast accessibility standards such as CEA-608/708, and its SyncWords Live offering provides professional captioning and real-time translated subtitles for webinars, streaming services, and hybrid events. The platform translates into a wide range of languages, including non-Latin scripts such as Cyrillic, CJK, Arabic, Hebrew, and Thai, and recent engineering work has driven latency down to roughly a second or less even in demanding live environments. Its newer Vocalics capability adds real-time AI voice dubbing that aims to preserve a speaker's tone and delivery across languages. Content is delivered through no-download widget URLs as well as streaming formats like HLS, SRT, CMAF, and VTT, with integrations spanning platforms such as AWS, YouTube, and Vimeo. SyncWords reports processing tens of thousands of events and hundreds of thousands of hours of media, and it received an industry innovation award in 2025, confirming active operation. It best fits broadcasters, media teams, and event organizers who need accessible, multilingual live captioning and translation at scale. Pricing varies by plan.
