How Hosiqo compares and tests toolsFinal recommendation
Shortlist CallBro when transcribing legal client meetings, consultations, and intake calls without a visible recorder 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.
Bot-free AI meeting assistant that transcribes calls from system audio and produces structured notes without joining the call.
Open-source, self-hosted real-time speech-to-text and speaker diarization toolkit with a FastAPI server and web interface, suitable for meeting transcription.
CallBro is a desktop AI meeting assistant that records and transcribes meetings in real time directly from your device's system audio and microphone, without sending a separate bot to join the call. Because capture happens locally at the system level, it works with any meeting platform, including Zoom, Google Meet, and Microsoft Teams, as well as in-person conversations, and it remains invisible to other participants. CallBro combines the live transcript with the user's own typed notes to generate structured summaries that highlight key decisions, action items, and next steps, and it includes an AI chat that can answer questions about the meeting or draft follow-ups using the full context of the transcript and notes. The product is offered as a downloadable application for macOS and Windows, with Linux noted as upcoming, and the website lists dedicated use cases for lawyers and students alongside general business meetings. Its bot-free, device-only approach makes it relevant for professionals handling sensitive conversations, such as legal client meetings and consultations, where a visible third-party recorder may be undesirable. 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.
