How Hosiqo compares and tests toolsFinal recommendation
Shortlist Felo Subtitles when following and translating multilingual video meetings on zoom, google meet, teams, or webex in real time matters most, and OpenTranscribe when collaborative review of transcripts with time-stamped annotations matters most. Run both through a week of actual calls to see which suits your workflow.

Felo Subtitles, made by Felo Inc. (Sparticle), is a real-time transcription and translation tool delivered as a Chrome/Edge browser extension plus companion desktop apps for Windows and macOS. It listens to meeting and video audio, recognizes speech, and overlays live captions with instant translation into other languages, so participants can follow conversations across language barriers. The browser extension captions web-based audio such as Google Meet (web), YouTube Live, Twitch, and Facebook Live, while the separate Felo desktop app extends coverage to Zoom, Microsoft Teams, Webex, and Tencent Meeting without a bot joining the call. It recognizes speech in roughly 23 languages and translates into about 20 target languages. Captured sessions can be saved as transcripts and exported as text, and the tool offers AI summaries using templates for contexts like sales, learning, and one-on-ones. Custom speech and translation dictionaries let teams add industry terminology. It is aimed at IT, research, HR, legal, education, and video-creator users needing multilingual meeting communication.

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.
