How Hosiqo compares and tests toolsFinal recommendation
Shortlist DubTab when following zoom, google meet or teams meetings in another language with live captions and dubbing matters most, and Olovka AI when converting youtube and online-course videos into organized notes matters most.

AI lecture recorder for students that captures, transcribes, and summarizes classes into organized notes.
DubTab is a browser extension for Chrome and Edge that translates spoken audio in real time as it plays in a browser tab. Rather than requiring file uploads or exports, it listens to the audio of whatever tab is playing and produces live translated subtitles on screen, optional bilingual (original plus translation) captions, and low-latency AI voice dubbing that speaks the translation aloud. The vendor states audio stays in the tab and only text segments are processed, and that translations appear with roughly half-a-second latency suitable for live content. It supports 50+ languages and offers voice selection and volume-ducking controls. Because it works on any site with audio, supported contexts include YouTube, Twitch, Netflix, Udemy, Coursera and Bilibili, as well as meeting and conferencing tools such as Zoom, Google Meet and Microsoft Teams, where it can show what participants are saying in real time. It is aimed at online learners, livestream and international-content viewers, and remote meeting participants who need on-the-fly interpretation and captioning.

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.
