How Hosiqo compares and tests toolsFinal recommendation
Shortlist Carv when transcribing and summarizing candidate interviews hands-free matters most, and Substrata when coaching sellers on social dynamics in high-stakes conversations matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

AI sales intelligence platform that analyzes the social and emotional signals behind conversations to help dealmakers read buyer intent.
Carv is an AI platform for recruiters that records, transcribes, and takes notes during interviews, intake calls, and hiring meetings so recruiters can stay present in the conversation rather than typing notes. During candidate interviews it captures a full verbatim transcript, flags any planned questions that went unanswered at the end of the call, and uses the transcript to auto-generate a candidate profile. For intake calls with hiring managers, Carv captures the requirements discussed and can automatically draft a job description in the recruiter's own style and tone of voice. Beyond note-taking, Carv positions itself as an agentic recruiting assistant that takes over repetitive administrative work, from document creation to updating the applicant tracking system, and includes an AI companion that carries context about how the user works. The platform integrates with ATS and HR systems and offers analytics and insights across recruiting activity. By turning recruiting conversations into structured notes, profiles, and documents, Carv aims to cut down on coordination and admin time so recruiters can focus on connecting with candidates and hiring managers. Pricing varies by plan. Check the official website for current pricing.

Substrata is an AI sales coaching and deal intelligence platform that takes a different angle from typical conversation intelligence tools: rather than focusing on transcription and summaries, it analyzes the social and emotional signals beneath sales conversations. Its core function is to model buyer psychology, attitudes, and momentum across interactions to help professional dealmakers understand intent and power dynamics. A central component is SoundWave, a real-time conversational analytics engine that listens to sales calls and analyzes voice tone, pace, pauses, interruptions, and the push-pull of social dynamics, surfacing the why behind what is being said rather than just the words. Substrata applies this signal analysis across conversations and email exchanges to gauge buyer sentiment and engagement, giving sellers and revenue leaders a read on how deals are actually progressing. The platform is aimed at B2B revenue professionals and leaders, and is positioned for smaller and mid-sized dealmaking teams that want behavioral insight into negotiations and high-value conversations. It has been recognized as a high performer across sales coaching, AI sales assistant, conversation intelligence, sales analytics, and revenue operations categories. Pricing varies by plan.
