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 WINN.AI when sales leaders standardizing methodology and execution across a team matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

A real-time AI sales assistant that joins calls to provide playbook guidance, capture data, take notes, and automatically update the CRM.
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.

WINN.AI is a real-time AI sales assistant built for sales reps, sales leaders, and revenue operations teams who want consistent execution on customer calls. During a meeting, WINN listens to the conversation and shows the rep, in real time, which playbook topics have been covered and which still need to be addressed, surfacing cues, suggested questions, and battle cards so reps stay on message and handle objections consistently. Sales leaders can encode their playbook and align it to common methodologies such as MEDDIC, MEDDPICC, SPICED, Challenger, and BANT so that the same process is reinforced across the whole team. Beyond live guidance, WINN automates the administrative side of selling: it takes notes, captures structured data from the conversation, updates CRM records including custom fields, and can draft follow-up emails and help with meeting preparation. It integrates with CRM and meeting platforms including Salesforce, HubSpot, Zoom, and Google Meet, syncing captured data automatically to reduce manual entry. WINN.AI is positioned as a revenue execution platform that combines real-time meeting coaching with automated note-taking and CRM hygiene, making it best suited to B2B sales teams that run structured discovery and demo calls.
