How Hosiqo compares and tests toolsFinal recommendation
Shortlist Aircall when running outbound and inbound sales calling with ai transcription matters most, and Callabo when logging sales and customer meetings into crm tools like salesforce or hubspot matters most. Run both through a week of actual calls to see which suits your workflow.

Korean AI meeting-notes service from Return Zero that records, transcribes, summarizes, and analyzes meetings for individuals and teams.
Aircall is a cloud-based phone and call center platform widely used by sales and support teams, with an integrated AI conversation intelligence layer that runs across calls rather than as a separate bolt-on system. Its core function is to handle business calling through features like power dialing, call recording, IVR, queueing, and routing, while Aircall AI transcribes conversations and analyzes them for insights. The conversation intelligence capabilities include AI-generated call summaries, key topic recognition, sentiment analysis, talk-to-listen ratios, transcription text search, and call scoring, which together help teams spot coaching opportunities and understand customer objections and buying signals. Aircall centralizes communications in a Workspace that brings voice, text, voicemail, and WhatsApp into a threaded view around each customer, with access to recordings and transcripts. The platform logs activity and transcripts to connected CRMs, and an analytics add-on extends dashboards with advanced filters, longer history, and KPI drill-downs. Aircall is aimed at sales and customer-facing teams that want a reliable cloud phone system with conversation intelligence included, rather than running a separate dialer and analysis tool. Pricing varies by plan. Check the official website for current pricing.
