High-accuracy automated transcription in 50+ languages
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.

Sonix is an automated transcription service that converts audio and video into accurate, searchable text across a wide range of languages. While not a meeting bot in the traditional sense, it is widely used to transcribe recorded meetings, interviews, podcasts, and videos, making it a core AI-transcription tool for teams that work with recorded conversations. Sonix provides an in-browser editor where users can review and correct transcripts, add timestamps and speaker labels, and search across content quickly. It also offers translation and subtitle features, which helps multilingual teams and content creators repurpose recordings. Because it focuses on high-quality transcription rather than live meeting assistance, Sonix is often paired with recording tools or used to process existing audio and video files. It is popular with researchers, journalists, podcasters, and businesses that need reliable transcripts they can edit, search, and translate, with an emphasis on accuracy and language coverage. Platforms: Web / upload audio and video. Integrations: Zapier, Google Drive. Pricing varies by plan. Check the official website for current pricing.
