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 Olovka AI when converting youtube and online-course videos into organized notes matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.

AI lecture recorder for students that captures, transcribes, and summarizes classes into organized 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.

Olovka AI is an AI lecture note-taking tool aimed at students who want to focus on listening rather than writing during class. The app records lectures with the goal of high transcription accuracy, provides real-time transcript conversion while recording, and then automatically produces structured, organized notes from the session. It accepts multiple input formats, including live classroom recordings, YouTube videos, and uploaded audio or PDF documents, so students can process both in-person lectures and online course material in one place. A notable capability is assignment detection, where the tool flags homework and tasks mentioned during a lecture so they are not missed. Generated notes are editable and printable, allowing students to refine them and study offline. The service offers free sign-up via Google authentication and runs on AI from OpenAI, with a flashcard feature listed as planned. Olovka positions itself squarely in the education niche for note capture and study, and is marketed toward students at a range of universities. It is best suited to individual learners rather than professional meeting documentation. Pricing varies by plan. Check the official website for current pricing.
