How Hosiqo compares and tests toolsFinal recommendation
Shortlist Boostlingo when adding live ai-translated captions to a webinar or virtual meeting 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.

Boostlingo is a language-access company whose product suite spans interpreter scheduling, on-site interpretation, remote video and phone interpretation, on-demand interpreter access, and AI-powered live captioning and translation. Its AI Pro engine provides transcription, live translation, and video captioning for meetings, events, and webinars, and the Boostlingo Events offering delivers continuous AI-translated captions for onsite, hybrid, and virtual sessions. Attendees can access live AI captions through a shared link or QR code without downloading anything, with captions appearing in their selected language in real time, and organizers can set default languages and enable automatic translation so the system streams translated captions throughout a session without manual switching. The platform supports a large number of languages and thousands of language pairs and integrates with major video-conferencing platforms including Zoom, Microsoft Teams, and Webex, as well as in-person and hybrid event setups. Boostlingo continues to expand its AI capabilities, including a more recent AI Interpreter that joins its AI captions and translations features. The product is actively operating in 2025/2026 and is well suited to event organizers, enterprises, and language-service providers that need scalable multilingual captioning and translation across both AI and human interpretation workflows. 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.
