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 VoicePen when transcribing lectures and turning them into study notes matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.

Apple-native AI app that records and transcribes meetings, lectures, and voice memos, then turns them into summaries and rewritten notes.
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.

VoicePen is a voice-first AI note taker built natively for the Apple ecosystem, running across iPhone, iPad, Apple Watch, and Mac. The app records and transcribes spoken audio into text, handling everything from short memos to long lectures, meetings, podcasts, and imported recordings. Once a recording is transcribed, VoicePen uses AI to generate easy-to-read summaries, structured notes, and study materials, and it offers a large set of rewrite options to reformat transcripts into bullet points, professional formats, or more casual styles. It can pull in audio and video from sources such as files, Voice Memos, Zoom recordings, podcasts, and YouTube, and it separates and labels different speakers within a transcript. A chat feature lets users ask questions about the transcribed content to surface key takeaways and action steps. VoicePen supports many languages, includes offline recording, and syncs data through iCloud, positioning itself as a personal second-brain capture tool for individuals who think and work by talking rather than typing. Pricing varies by plan. Check the official website for current pricing.
