How Hosiqo compares and tests toolsFinal recommendation
Shortlist Clevercast when adding live multilingual closed captions and subtitles to conferences and webinars matters most, and OpenTranscribe when collaborative review of transcripts with time-stamped annotations matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

Clevercast is a SaaS platform for multilingual live streaming and accessibility, aimed at organizations broadcasting events, conferences, webinars, and meetings to global audiences. Incoming audio and video are sent from an encoder to Clevercast, which generates AI closed captions described as having high accuracy, including for streams where multiple languages are spoken. From that speech-to-text source it can produce live subtitles in multiple languages, synthetic AI voice translations that viewers select per language, and on-site scrolling transcripts displayed on screens for event attendees. A web interface lets operators correct the AI transcription in real time, improving the resulting captions and translations, and remote human interpreters can also be added for events with strict quality requirements. Streams are delivered via HLS through a global CDN and can be embedded in Clevercast's player or distributed to platforms such as YouTube. It suits enterprises, international bodies, educational institutions, and media companies that need accessible, language-inclusive live broadcasts rather than a personal meeting note-taker.

OpenTranscribe is a self-hosted, containerized web application for transcribing and analyzing audio and video files using current AI models. It is built with a FastAPI backend, a Svelte/TypeScript progressive web app frontend, and a Docker-based stack that includes PostgreSQL, Redis/Celery task queues, MinIO object storage, and OpenSearch for full-text indexing. Transcription is handled by WhisperX with the large-v3-turbo model and Faster-Whisper, supporting more than 100 languages, while automatic speaker diarization uses PyAnnote v4 with overlap detection. The project is licensed under AGPL-3.0 and is actively maintained, with v0.4.1 released in April 2026. Beyond transcription, OpenTranscribe provides AI-powered summarization (including BLUF-format and custom JSON schemas), topic extraction, and content analysis through multiple LLM providers such as OpenAI, Claude, vLLM, Ollama, and OpenRouter. Collaboration features include time-stamped comments and annotations, and the platform can automatically import media from local folders, S3, and SMB shares. It also supports a set of cloud ASR providers as alternatives to local transcription, giving teams flexibility between fully local processing and managed services while keeping the application running on their own infrastructure. Pricing varies by plan. Check the official website for current pricing.
