How Hosiqo compares and tests toolsFinal recommendation
Shortlist Acta.ai when sales discovery calls that need deal briefs and follow-up tasks matters most, and WhisperLiveKit when building privacy-first transcription into custom applications via compatible apis matters most. Try them side by side on real calls before deciding — needs vary by team.

Acta.ai is an AI meeting assistant developed by Agilean Solutions Private Limited, an India-based company. It connects to a user's Google or Microsoft account and calendar, and its agent automatically joins scheduled meetings on Google Meet, Microsoft Teams, and Zoom. After a meeting, Acta.ai records and transcribes the conversation and then analyzes it to generate a concise summary, a list of decisions, and actionable tasks. A distinguishing element is its persona-based approach: the platform offers domain-specific agents oriented toward business functions such as Sales, Engineering, Recruiting, Project Management, Finance, Customer Support, and HR, with the ability to convert discussions into role-appropriate outputs like product requirement notes, ticket-style items, deal briefs, or assessment reports. It also includes an 'Ask Acta' assistant for querying meeting content and provides a Chrome extension. Acta.ai is positioned for cross-functional teams that want meetings translated into structured follow-up work rather than only a raw transcript, and it markets itself around moving from 'what was said' to 'what needs to be done.' The product is actively operating, offering a free trial alongside paid tiers. 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.
