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 Symbl.ai when scoring and analyzing sales calls for coaching matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

Developer conversation-intelligence API for transcribing and analyzing voice, video, and chat conversations.
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.

Symbl.ai is a conversation-intelligence platform delivered as APIs and SDKs that lets developers transcribe and analyze voice, video, and chat conversations, including meetings and customer calls. Beyond raw transcription, Symbl.ai focuses on extracting structure and meaning from conversations: it can generate speaker-attributed transcripts, summaries, topics, action items, questions, and entities, and it can score calls and monitor sentiment in real time. It supports both real-time streaming over WebSocket for live meetings and processing of recorded audio and video, which makes it suitable for building meeting assistants as well as sales and support analytics tools. The platform is now part of Invoca and continues to operate, targeting enterprises that want to embed real-time AI agents and analytics into their own products rather than buy a finished end-user application. Typical implementations include adding live transcription and summaries to a conferencing tool, scoring and coaching sales calls, and surfacing compliance or quality signals from conversations. Because it is developer-first, using Symbl.ai requires engineering work to integrate its APIs into an existing application or workflow. Pricing varies by plan. Check the official website for current pricing.
