Shortlist BB Recorder when regulated or privacy-sensitive teams that cannot send audio to the cloud matters most, and Knowt when generating flashcards and practice tests from course materials before exams matters most. Run both through a week of actual calls to see which suits your workflow.

AI study platform that turns recorded or uploaded lectures into notes, flashcards, and practice quizzes for students.
BB Recorder is a local-first meeting recorder built by the team behind BuildBetter, designed for people who want meeting capture without any data leaving their device. Rather than dropping a bot into a video call, BB Recorder captures the computer's system audio directly, links to the user's calendar, and turns rough conversation audio into clean transcripts and summaries. Its defining characteristic is that recording, transcription, summarization, and even live AI chat about the meeting can all run locally using on-device models, so there is no server holding the audio or transcripts. The company frames this as making a data breach architecturally impossible because there is no cloud store to compromise, and it points to SOC 2 and HIPAA considerations along with an AI transparency policy. BB Recorder is positioned as a genuinely free, unlimited option for Mac, with no trial tiers or required registration when using local models, and a companion iOS app extends capture to the iPhone. It is aimed at privacy-sensitive professionals, regulated teams, and anyone who wants automatic meeting notes without a visible bot or a cloud transcription pipeline. Pricing varies by plan.

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.
