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 Mem when asking questions across an entire personal knowledge base matters most. Try them side by side on real calls before deciding — needs vary by team.

AI second-brain notes app that organizes captured information automatically and can record, transcribe, and summarize meetings.
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.

Mem is an AI-powered notes application positioned as an AI thought partner and second brain, built around the idea that users should not have to manually file information into folders and tags. Users capture notes through typing, voice brain dumps, a Chrome extension for web clipping, and mobile messaging for quick capture on the go, and Mem's AI organizes that material automatically into collections. For meetings, Mem can record, transcribe, and take notes, attaching both the audio and transcript for reference and cleaning up the result into structured notes. Its chat interface lets users ask questions in plain language across their entire note history, with answers synthesized from their own notes and cited to specific sources, so they can recall facts, summarize a span of meetings, or reorganize content by project or topic. A Heads Up feature surfaces related notes and timelines as context. Mem is aimed at knowledge workers, researchers, founders, and anyone who attends many meetings and wants a low-friction way to capture, retrieve, and synthesize information without spending time on manual organization. Pricing varies by plan. Check the official website for current pricing.
