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 Knowt when generating flashcards and practice tests from course materials before exams matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.

AI study platform that turns recorded or uploaded lectures into notes, flashcards, and practice quizzes for students.
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.

Knowt is an AI-powered study platform built primarily for students and teachers that converts lectures and learning materials into organized study resources. Students can record a lecture live in the app or on the website, or upload existing audio, video, PDFs, and slide decks, and the platform's AI assistant (called Kai) generates summarized notes, flashcards, and practice quizzes from the content. Notes can be formatted as outlines or paragraphs, with adjustable detail levels, and the original audio is saved for reference. Beyond capture and transcription-driven summarization, Knowt functions as a broader study workspace, positioning itself as a free alternative to traditional flashcard apps and offering a large library of community-shared study materials. It also includes teacher-facing features for assigning material and tracking student progress. The tool spans web, iOS, and Android, making it usable across classroom, online-course, and self-study settings. Knowt is aimed at learners who want lecture capture to flow directly into reusable, exam-oriented study artifacts rather than just raw transcripts. Pricing varies by plan. Check the official website for current pricing.
