How Hosiqo compares and tests toolsFinal recommendation
Shortlist Aircall when running outbound and inbound sales calling with ai transcription matters most, and Koji when building personas and validating early product concepts at scale matters most. Test each on your own meetings; the right choice tends to become obvious quickly.
Cloud phone and call center platform with built-in AI conversation intelligence: transcription, call summaries, sentiment, and call scoring.
AI-native customer research platform whose AI interviewer runs voice and text discovery conversations at scale, then synthesizes themes automatically.
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.

Koji is an AI-native customer research platform built around an AI interviewer that conducts natural, in-depth conversations with research participants at scale, removing the need to schedule and moderate live discovery calls one at a time. Teams describe what they want to learn, and an AI research agent helps define goals and generate an interview guide. The AI then runs the interviews asynchronously in either a text chat or spoken voice format, asking adaptive follow-up questions and probing for depth as a human moderator would. Each completed conversation is analyzed automatically for key moments and sentiment, and findings are synthesized across all interviews into study-wide reports surfacing themes, patterns, and recommendations, with every insight traceable back to the participant quote that supports it rather than presented as a black-box summary. Koji is used for exploratory work such as discovery, persona development, and market strategy, as well as concept and messaging testing. The product is operated from Amsterdam with EU data residency and GDPR compliance, offers a freemium entry point, and integrates with tools including Claude, ChatGPT, Cursor, and Notion via an MCP server. Pricing varies by plan. Check the official website for current pricing.
