How Hosiqo compares and tests toolsFinal recommendation
Shortlist Callabo when turning recurring internal team meetings into shareable summaries and action items matters most, and Klu when teams that want meeting follow-ups auto-assigned and routed into slack or notion 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.

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.

Klu (klu.so) is an AI meeting assistant that positions itself as a meeting automation platform for modern teams rather than a transcription-only tool. It captures meetings through a browser extension that can auto-join calls, a Mac desktop app, and offline capture for in-person conversations. During and after a meeting, Klu produces a transcript with speaker recognition, generates bullet-point summaries, surfaces action items, and supports custom note sections, alongside a smart-search and Ask AI capability for retrieving details from past conversations. A Deep Dive feature lets users ask questions that span multiple meetings, such as what was committed to with a particular account over a period of time. On the workflow side, Klu detects follow-ups, assigns them to owners with deadlines, and can push them into tools like Slack and Notion. For CRM users, Klu logs meeting outcomes to HubSpot, Salesforce, and Pipedrive on the relevant record, and connects to additional CRMs such as Attio and Affinity through Zapier, helping keep deals and accounts current without manual data entry. It maintains comparison pages against established notetakers and supports multilingual transcription. Pricing varies by plan. Check the official website for current pricing.
