Shortlist CFAI when capturing private meeting notes and summaries without a recording bot joining the call matters most, and Soniox when building voice agents and dictation features into apps matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

Multilingual speech AI platform offering real-time and async speech-to-text and translation APIs for meetings and voice apps.
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.

Soniox is a multilingual speech AI platform that provides speech-to-text, translation, and text-to-speech APIs aimed at developers building voice-enabled applications, including meeting transcription, voice agents, dictation, and call-center tools. Its speech recognition supports real-time streaming with low latency as well as asynchronous processing of recorded files, and it covers a broad set of languages with the ability to handle conversations where speakers switch languages mid-sentence. For meeting and multi-party scenarios, Soniox offers speaker separation so transcripts can attribute speech to individual participants, along with handling of names, alphanumerics, and domain-specific terms. The platform also includes real-time speech translation across many language pairs, which is useful for international calls and meetings. Soniox markets enterprise-grade compliance, including SOC 2 Type 2, ISO 27001, HIPAA, and GDPR, and offers multi-region deployment with data-residency options and a privacy-oriented architecture where audio is processed in real time. Because it is delivered as APIs and SDKs, organizations typically embed Soniox into their own products rather than using it as a standalone meeting application. Pricing varies by plan. Check the official website for current pricing.
