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 SpeakNotes when extracting action items and decisions from long calls matters most. Try them side by side on real calls before deciding — needs vary by team.

Browser-based AI tool that turns uploaded or recorded meeting audio and video into structured summaries with action items and decisions.
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.

SpeakNotes is an AI-powered transcription and summarization platform that converts audio and video recordings into structured written content. Its workflow has three steps: users upload audio or video files, paste a YouTube link, or record directly in the browser; the system transcribes and analyzes the content; and it returns a structured summary in a chosen format. For meetings, SpeakNotes is designed to extract action items, decisions, and key discussion points, making it suited to turning recorded calls into usable minutes. It supports speech-to-text across 50+ languages and offers 15+ output formats, including meeting notes, transcripts, blog posts, and flashcards, with export to tools such as Notion and Obsidian. The product is browser-based with direct upload and YouTube integration rather than a meeting bot, so it is oriented toward processing existing recordings and in-browser capture. SpeakNotes targets professionals who work with recorded content, including meeting participants who need post-call summaries, as well as students, researchers, podcast listeners, and content creators who want condensed, structured takeaways from long audio or video. Pricing varies by plan. Check the official website for current pricing.
