How Hosiqo compares and tests toolsFinal recommendation
Shortlist Callabo when turning recurring internal team meetings into shareable summaries and action items matters most, and oTranscribe when academic and qualitative researchers transcribing fieldwork or oral-history recordings matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.

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.

oTranscribe is a free, open-source (MIT license) web app, created by Elliot Bentley and maintained by the MuckRock Foundation, that takes the pain out of transcribing recorded interviews. It runs in the browser on desktop computers and places an integrated audio or video player alongside a text editor, so you can pause, rewind, and fast-forward your recording using keyboard shortcuts without taking your hands off the keys or switching between apps. It is built for journalists, researchers, oral historians, and students who type up interviews and recordings themselves. Rather than using automatic speech recognition, oTranscribe assists manual transcription: you listen and type, inserting interactive timestamps (Ctrl+J) that you can click to jump back to that moment in the media. Your transcript autosaves to the browser's local storage, and audio files never leave your computer, keeping work private. Finished transcripts can be exported to Markdown, plain text, or oTranscribe's own .otr format, or sent to Google Drive. Rich-text formatting and adjustable playback speed are supported.
