Shortlist Aiko when transcribing recorded lectures into searchable text for studying matters most, and Mem when asking questions across an entire personal knowledge base matters most. Run both through a week of actual calls to see which suits your workflow.

AI second-brain notes app that organizes captured information automatically and can record, transcribe, and summarize meetings.
Aiko is a native transcription app for macOS, iOS, and visionOS, developed by Sindre Sorhus, that converts speech to text from meetings, lectures, and recordings entirely on-device. It uses OpenAI's Whisper model running locally, so audio never leaves the user's device, which makes it appealing for students and professionals with privacy requirements. Aiko transcribes both audio and video files in common formats such as .m4a, .wav, .mp3, .mp4, and .mov, and supports around 100 languages. Transcriptions can be exported in multiple formats, including JSON, CSV, and SRT subtitles, and the app includes a word-replacement feature to automatically correct recurring errors. It also integrates with Apple Shortcuts for automation workflows. Because Aiko prioritizes accuracy over speed, it does not perform live transcription while recording and currently does not include speaker detection, so it is best for transcribing recorded lectures, interviews, and meetings after the fact. The app is offered as a Universal Purchase with a free trial via TestFlight, making it a low-cost, privacy-first option for turning lecture and meeting recordings into searchable text. Pricing varies by plan. Check the official website for current pricing.

Mem is an AI-powered notes application positioned as an AI thought partner and second brain, built around the idea that users should not have to manually file information into folders and tags. Users capture notes through typing, voice brain dumps, a Chrome extension for web clipping, and mobile messaging for quick capture on the go, and Mem's AI organizes that material automatically into collections. For meetings, Mem can record, transcribe, and take notes, attaching both the audio and transcript for reference and cleaning up the result into structured notes. Its chat interface lets users ask questions in plain language across their entire note history, with answers synthesized from their own notes and cited to specific sources, so they can recall facts, summarize a span of meetings, or reorganize content by project or topic. A Heads Up feature surfaces related notes and timelines as context. Mem is aimed at knowledge workers, researchers, founders, and anyone who attends many meetings and wants a low-friction way to capture, retrieve, and synthesize information without spending time on manual organization. Pricing varies by plan. Check the official website for current pricing.
