AI note taker for students that turns lectures, audio, slides, PDFs, and videos into notes and study packs.
Aqua Voice is an AI dictation tool built by Aqua Voice, Inc. (a Y Combinator startup) that converts spoken words into written text in real time. Rather than a standalone transcription window, it works system-wide: users hold a key (such as Space) and speak, and the dictated text is inserted into whatever app is in focus, including Gmail, Google Docs, Slack, code editors, and AI chat tools. It runs on macOS and iOS, with the iPhone app now live. Aqua is powered by Avalon, the company's proprietary speech-to-text model trained on prompt-style speech, code, and email, and it refines grammar and phrasing as you talk. It supports context awareness of on-screen content, a custom dictionary for technical terms and names, natural-language editing commands ("make this a list," "rephrase that"), style adaptation, and multilingual input across dozens of languages. It is aimed at developers, knowledge workers, and content creators who want a faster alternative to typing for emails, documents, messages, prompts, and code.

Polar Notes (PolarNotes AI) is an AI note-taking tool built for students and teachers that converts lectures and course materials into organized study resources. Users can record or upload a lecture, paste a YouTube link, or import slides and PDFs, and the app automatically transcribes audio when needed and analyzes the content to produce summarized notes, key concepts, section headings, and short overviews. From the same source material it can generate a study pack that includes study guides, flashcards, and assessment questions, and results can be exported to Google Docs or PDF with study sets organized in one place. Polar Notes emphasizes privacy and offline access on iOS, keeping notes stored locally on the device unless the user chooses to back them up or share them, which lets students review notes without an internet connection. It also supports multilingual transcription, making it usable for international students and teachers recording in different languages. The tool is delivered as an iOS app with an accompanying web experience and free online tools, and is aimed at learners who want lecture and document content distilled into exam-ready study material rather than verbatim meeting records. Pricing varies by plan. Check the official website for current pricing.
