How Hosiqo compares and tests toolsFinal recommendation
Shortlist Carbon Voice when replacing status meetings and calls with async voice messages that get auto-transcribed and summarized matters most, and Nimitai when preparing reps with research and briefings before customer meetings matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.

An AI conversation-intelligence copilot for B2B sales teams that researches prospects, briefs reps, and delivers real-time coaching during calls.
Carbon Voice is an asynchronous voice-messaging and voice-notes app for iOS, Android, Web, and Apple Watch. Users record voice memos or messages with a single keystroke or swipe, and every message is automatically transcribed so it can be read, searched, labeled, and organized. The app is built around reducing real-time meetings and calls: instead of scheduling synchronous time, teammates exchange voice messages that the recipient can catch up on later. Layered on top is a large library of AI actions that turn raw voice into structured content — bulleted summaries, cleaned-up transcripts (removing filler words and fixing grammar), meeting notes, agendas, action items, professional emails, and longer documents such as PRDs and reports. Users can also query an AI assistant about any chat. A Global Voice feature can translate messages between languages, and messages can be sent to people who don't have the app via a secure email link. It is aimed at distributed teams, managers, and individuals who prefer talking over typing.

Nimitai is an AI meeting-intelligence and conversation-analytics platform built specifically for B2B sales teams at startups and growth-stage companies. It is structured around specialized functions: a research step that pulls prospect intelligence before a call, a preparation step that generates pre-call briefings with talking points and deal context, and a live copilot that delivers real-time coaching during the meeting. Nimitai captures calls through a lightweight Chrome extension that works with Zoom, Google Meet, and Microsoft Teams without requiring a separate bot to join the call. During a live conversation it records and analyzes audio and engagement signals, surfaces coaching cues, flags unaddressed objections, detects shifts in buyer interest, and highlights deal-risk signals so reps can adjust in the moment. After the call it generates structured scorecards and call summaries and can sync them to CRMs such as Salesforce, HubSpot, and Pipedrive, reducing manual data entry. It is aimed at sales organizations that want both real-time selling assistance and post-call analytics in a single tool, positioned as an option for smaller revenue teams. The platform is operating and accepting B2B sales teams. Pricing varies by plan. Check the official website for current pricing.
