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 FlashRev when reviewing recorded calls with ai summaries and sentiment for coaching matters most. Run both through a week of actual calls to see which suits your workflow.

AI parallel dialer within the FlashLabs go-to-market platform, with call recording, real-time conversation analysis, and AI summaries.
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.

FlashRev is the AI go-to-market product from FlashLabs (previously branded FlashIntel) that pairs outbound calling with conversation intelligence for B2B sales teams. Its AI parallel dialer places multiple outbound calls at once and connects reps instantly when a prospect answers, skipping unanswered calls and answering machines so sellers focus on live conversations. The platform records and tracks calls and analyzes each connected conversation in real time, automatically generating intent labels, converting transcripts into concise summaries, and identifying conversation sentiment at scale to support review and coaching. FlashRev positions itself as a broader revenue platform that combines prospecting data, omnichannel engagement across email, SMS, social, and calls, and AI sales-development automation, with the parallel dialer as one component of that suite. It integrates with common CRMs and sales-engagement tools such as Salesforce, HubSpot, Salesloft, and Outreach. The product is live and marketed to outbound and revenue teams; FlashLabs publicly announced an unlimited parallel-dialing capability and continues to develop the platform into 2025 and 2026. Pricing varies by plan. Check the official website for current pricing.
