How Hosiqo compares and tests toolsFinal recommendation
Shortlist Callabo when turning recurring internal team meetings into shareable summaries and action items matters most, and Meeting BaaS when developers building custom ai notetakers or meeting analytics matters most. Run both through a week of actual calls to see which suits your workflow.

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.

Meeting BaaS ("Meetings Bots as a Service") is a developer-focused API platform operated by the French company SAS Spoke. Rather than being an end-user meeting assistant, it provides the infrastructure that lets developers programmatically send recording bots into online meetings and retrieve the resulting data. Through a single unified API, SDKs, and HTTP requests, developers can start recording meetings across Zoom, Google Meet, and Microsoft Teams, then access raw audio and video, full transcripts, and speaker metadata with timestamps. Transcription can be produced via providers such as Gladia or a developer's own service, and the platform offers webhooks and MCP servers for integration, plus the ability to self-host on a developer's own infrastructure. Because it exposes the underlying capture and transcription layer, Meeting BaaS is the building block companies use to add meeting recording, transcription, and AI features to their own products without each maintaining separate bots for every conferencing platform. It is best for engineering teams and startups that want to embed meeting capture and transcription into their applications rather than buy a finished notetaker. Pricing varies by plan. Check the official website for current pricing.
