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.

TranscribeAudio is a Chrome browser extension that captures the audio playing in any browser tab and turns it into real-time text, displayed in a repositionable floating caption overlay while you keep working. It is aimed at people who want live captions and transcripts for online meetings, lectures, courses, podcasts, webinars, and videos. Because it works from tab audio rather than joining calls as a meeting bot, it can transcribe Zoom, Google Meet, YouTube, Vimeo, and essentially any site with audio or video without sending notifications into the call. Transcription is powered by OpenAI's Whisper-based speech recognition, which the company says handles accents, background noise, and specialized terminology, and supports over 50 languages. Setup is a three-step flow: install from the Chrome Web Store, sign in, then click Start Transcribing on a tab. Finished transcripts can be exported as text files for notes, summaries, or sharing, with cloud storage listed as an upcoming feature. The product offers a free tier with paid upgrades for more usage, languages, and faster transcription.
