How Hosiqo compares and tests toolsFinal recommendation
Shortlist Callabo when turning recurring internal team meetings into shareable summaries and action items matters most, and Recolx when capturing lectures or interviews and turning them into structured transcripts and briefs matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

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.

Recolx is an AI voice-recording and note-taking system that pairs portable hardware devices (the Recolx Tap, Tap Pro, and AI earbuds) with a companion mobile and web app. You capture a conversation with one tap, and the platform transcribes the audio with speaker identification, then automatically produces organized notes, summaries, and "AI Briefs" surfacing key points, decisions, and action items. Transcription covers a wide range of languages, and the app adds live speech-to-text while recording plus translation features. The hardware uses a multi-microphone array with 360-degree AI noise reduction for clearer capture in noisy settings, with long continuous recording on a charge. A library of professional templates formats notes for meetings, lectures, interviews, sales calls, and legal use, and finished content can be exported to PDF, Word, or Markdown or shared to Notion, Google Docs, and Slack. It targets professionals such as attorneys, salespeople, students, and researchers who want to stay engaged in a conversation while documentation happens automatically. The app works with the hardware or with standalone recordings.
