How Hosiqo compares and tests toolsFinal recommendation
Shortlist Allo when sales teams that want every outbound and inbound call recorded, transcribed, and logged to the crm automatically matters most, and Carbon Voice when capturing spoken ideas and turning them into structured documents, emails, or action items matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.

Carbon Voice is an asynchronous voice-messaging app that automatically transcribes voice memos and uses AI to generate summaries, action items, and documents.
Allo is an AI-powered business phone system aimed at sales teams, support, and operations that records every call, transcribes it in real time, and syncs the recording, transcript, and an AI-generated summary to a CRM automatically. Positioned as mobile-native and quick to set up, it focuses on letting reps spend time selling rather than logging calls. Each conversation is recorded with consent-message compliance options, transcribed with speaker identification, and condensed into a shareable AI recap. Allo can then draft personalized follow-up emails and SMS based on what was discussed. The platform includes an AI receptionist for answering inbound calls, voicemail transcription, multi-tag organization of calls, and team collaboration features such as cascade ring and warm transfers. Managers can pull call recordings and AI transcripts to find coaching opportunities, while reporting dashboards surface connection rates, conversion tracking, funnels, and heatmaps. Allo integrates with CRMs including HubSpot, Salesforce, Pipedrive, Attio, and Apollo, and exposes an MCP endpoint to connect the phone system to AI assistants. It is a live, operating product as of 2025/2026. Pricing varies by plan. Check the official website for current pricing.
Best suited for
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.
