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.

Genio, formerly known as Glean, is an assistive note-taking platform that helps students capture and learn from lectures and classes. It records class audio and provides live captions during the session, then generates a full transcript afterward, letting students focus on understanding rather than frantically writing notes. Genio lets learners add their own notes, organize material with AI-generated outlines, import slides and reading material, and review with study features such as quizzing, tying recorded audio together with class content. The platform is widely used by students, including learners with specific learning difficulties, and is adopted by educational institutions that provide it as a study and accessibility support tool. It works online or offline across devices, which suits classroom and lecture-hall environments. Genio is positioned as a mainstream learning tool that also supports accessibility needs. It is actively operating in 2025 and 2026, reporting use by well over a hundred thousand students and more than a thousand institutions, with active sign-in, pricing, and ongoing product development. Pricing varies by plan. Check the official website for current pricing.
