Shortlist CFAI when capturing private meeting notes and summaries without a recording bot joining the call matters most, and Sonix when interview and podcast transcription matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.

High-accuracy automated transcription in 50+ languages
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.

Sonix is an automated transcription service that converts audio and video into accurate, searchable text across a wide range of languages. While not a meeting bot in the traditional sense, it is widely used to transcribe recorded meetings, interviews, podcasts, and videos, making it a core AI-transcription tool for teams that work with recorded conversations. Sonix provides an in-browser editor where users can review and correct transcripts, add timestamps and speaker labels, and search across content quickly. It also offers translation and subtitle features, which helps multilingual teams and content creators repurpose recordings. Because it focuses on high-quality transcription rather than live meeting assistance, Sonix is often paired with recording tools or used to process existing audio and video files. It is popular with researchers, journalists, podcasters, and businesses that need reliable transcripts they can edit, search, and translate, with an emphasis on accuracy and language coverage. Platforms: Web / upload audio and video. Integrations: Zapier, Google Drive. Pricing varies by plan. Check the official website for current pricing.
