How Hosiqo compares and tests toolsFinal recommendation
Shortlist CFAI when capturing private meeting notes and summaries without a recording bot joining the call matters most, and Vexa when streaming live, speaker-labeled transcripts into applications matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.

API-first, open-source meeting transcription platform that deploys bots to capture real-time, speaker-labeled transcripts for developers.
CFAI (Cognitive Flow AI) is a Windows desktop application that acts as a privacy-focused AI meeting and call note taker. Instead of sending a bot into the call, it captures both microphone and system audio at the operating-system level, so no "recording started" notification appears and the tool works across Zoom, Teams, Google Meet, Discord, and any other call. Transcription runs locally on the device using Faster Whisper, with support for many languages, and CFAI states that the audio never leaves the user's computer. From the live transcript it produces speaker-labeled notes, AI summaries, and action items, and it can build a real-time "Cognitive Map" that visualizes the conversation's topics. Summaries can be generated by Claude in the cloud, or users can keep everything offline by connecting a local LLM through Ollama, LM Studio, or Jan.ai. It is aimed at professionals, educators, recruiters, and others who want meeting notes without bots or cloud audio uploads. CFAI is distributed via the Microsoft Store with a free trial and credit-based subscription tiers.

Vexa is an API-first, open-source meeting transcription and intelligence platform aimed primarily at developers and technical teams who want to build meeting features into their own products. Rather than being a polished end-user notetaking app, Vexa provides a developer toolkit: it deploys bots that join meetings via a URL, capture audio, and stream back real-time, speaker-diarized transcripts with low latency over WebSocket, alongside REST interfaces for programmatic bot control. Captured data can be stored and queried for retrieval and export, enabling teams to build live transcription, searchable meeting repositories, or downstream analysis on top of the platform. Vexa currently supports Google Meet and Microsoft Teams, with Zoom support indicated as planned, and its codebase is available on GitHub under an Apache 2.0 license, with both self-hosted and managed cloud deployment options. Because it exposes meeting capture and transcription as programmable infrastructure, Vexa is suited to engineering teams in areas like sales, recruiting, and other domains that need to embed meeting intelligence into custom workflows rather than rely on a standalone consumer app. It is best for developers who want control over how transcripts are captured, stored, and used. Pricing varies by plan. Check the official website for current pricing.
