AI second-brain notes app that organizes captured information automatically and can record, transcribe, and summarize meetings.
123 Notetaker AI is an AI meeting notes and transcription app for Microsoft Teams, built by BlueSky Apps. It runs entirely inside the Teams interface and does not depend on Microsoft Copilot, giving teams an independent option for capturing meetings. During a call, participants can open the app from the meeting window to follow AI-powered transcription that appears in real time in the Teams app sidebar. After the meeting ends, 123 Notetaker AI generates a summary and emails the meeting notes, while transcripts and notes are stored in the user's BlueSky account for later reference. Because it is installed from the Microsoft commercial marketplace and operates within Teams rather than as a browser overlay or external bot, it fits organizations that want note-taking contained in their existing Teams workflow. BlueSky Apps offers a family of conferencing add-ons across Teams, Zoom, and Google Meet, and provides a free plan with paid upgrades for additional capacity and features. The app is currently listed and operating in 2025-2026, and is documented in the company's help center and several third-party Teams tool roundups. 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.
