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 Celeste AI when companies needing pay-as-you-go transcription without fixed subscriptions matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

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.

Celeste AI is a Brazilian voice AI and transcription platform that specializes in Portuguese, particularly Brazilian Portuguese, while also processing audio in additional languages such as English, Spanish, German, Italian, and French. Originally known for automated audio-to-text transcription that the company positions as far more efficient than manual transcription, Celeste AI has expanded into a broader suite that includes a Meeting Assistant (Assistente de Reunião) and AI Notes (Notas de IA), alongside transcription and quality-monitoring offerings. The platform uses machine learning speech models tuned for Portuguese and is offered both as an on-demand service and via an API, so users and businesses can transcribe content as needed. Its on-demand model lets customers pay only for the hours they actually use by purchasing credits, with flexible subscription plans available for those who have recurring transcription needs. As a Brazilian company connected to local institutions such as FGV Ventures and the São José dos Campos technology park, Celeste AI is oriented toward the Brazilian market and Portuguese-language workflows, and it reports a growing user base. The service is currently operating, with a functioning login, demo requests, and support, and is suited to professionals and companies that need accurate Portuguese transcription and meeting documentation. Pricing varies by plan. Check the official website for current pricing.
