How Hosiqo compares and tests toolsFinal recommendation
Shortlist 3Play Media when captioning recorded lectures, webinars, and corporate videos matters most, and WhisperLiveKit when building privacy-first transcription into custom applications via compatible apis matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.
Video accessibility platform combining AI and human review for captioning, transcription, and localization.
Open-source, self-hosted real-time speech-to-text and speaker diarization toolkit with a FastAPI server and web interface, suitable for meeting transcription.
3Play Media is a video accessibility and localization platform that combines automatic speech recognition with human review to produce transcripts and captions for organizations that need accuracy and compliance. The company's core services include closed captioning for recorded video, transcription, subtitling, audio description, and dubbing, along with live captioning for events and meetings. By blending machine processing with professional editing, 3Play Media aims to deliver high-accuracy output even when audio quality is poor or there are multiple speakers, accents, or specialized content. The platform offers a secure online account for managing media projects and provides a large set of integrations with video platforms and learning systems, as well as API access for automating captioning and transcription workflows. It serves sectors such as media and entertainment, higher education, corporate enterprises, sports broadcasting, and eLearning, where accessibility regulations and quality standards are important. Security and compliance are emphasized, including HIPAA compliance and regular security audits. Organizations typically choose 3Play Media when they need accountable, reviewed captions and transcripts integrated into established media and meeting workflows rather than fully automated, instant output. Pricing varies by plan. Check the official website for current pricing.

WhisperLiveKit is an open-source, self-hosted toolkit for ultra-low-latency real-time speech-to-text and speaker diarization. Rather than naively running Whisper on each audio chunk, it uses state-of-the-art simultaneous-speech research for intelligent buffering and incremental processing, which preserves transcription quality while streaming results with minimal latency. The project ships a complete backend built on FastAPI with WebSocket support, an OpenAI-compatible REST API, a Deepgram-compatible WebSocket protocol, and a simple, customizable HTML and JavaScript web interface that captures microphone audio and streams it to the server. It supports multiple ASR backends including Whisper variants, Voxtral, and Qwen3-ASR, covers 200+ languages with translation, and includes real-time speaker diarization and voice activity detection to reduce processing overhead. It can handle multiple concurrent users on a single backend and is distributed via PyPI with Docker images for both GPU and CPU. Licensed under Apache 2.0 and actively maintained into 2026, the project explicitly lists meeting transcription, accessibility tooling, and podcast or call transcription with speaker identification among its intended use cases, making it a practical building block for private, on-premise meeting transcription pipelines. Pricing varies by plan. Check the official website for current pricing.
