AI second-brain notes app that organizes captured information automatically and can record, transcribe, and summarize meetings.
Callabo (콜라보) is an AI meeting assistant developed by Return Zero (리턴제로), a Korean speech-AI company. It automatically records, transcribes, summarizes, and analyzes business meetings for both individuals and enterprise teams, aiming to turn a one-hour meeting into organized notes with a single click and no complex setup. Callabo connects to online meetings on Google Meet, Microsoft Teams, Zoom, and Webex, and also supports recording in-person meetings. After a meeting it produces transcripts, paragraph summaries, key discussion points, and action items with timestamped source quotes, and it can automatically detect the meeting language to handle multilingual conversations. An AI chat feature lets users ask follow-up questions about a meeting beyond the generated insights. The service integrates with workflow tools including Google Calendar, Outlook, Salesforce, Pipedrive, HubSpot, Slack, Microsoft Teams, Zapier, Notion, Confluence, and Linear. For enterprises, Callabo provides meeting access controls, team and member permission management, original-media retention settings, two-factor authentication, IP access restrictions, and audit logs, and it holds ISO/IEC 27001 certification. Mobile apps are available for both iOS and Android. 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.
