#1: Noter AI

Noter AI is the app this site is about. It was built for meetings, and a lecture is the same job: one long recording in a room, turned into notes you can act on.

Open Noter AI from the Control Center widget, tap record, then lock the phone and put it on the desk. When you stop, an hour of audio comes back as a finished note in about two minutes.

• A full transcript with timestamps and synced playback. Tap a line you did not catch and the audio jumps to that moment.
• Revision notes in the shape you want. Pick key bullet points for a revision sheet, a to-do list for the readings, a formal report for a write-up, or describe your own style once with a custom instruction.
• Readings and deadlines pulled out for you. "Chapter 12 before the seminar" and "problem set due Friday" land in the action items, even when they were said while everyone was packing up.
• Lectures in any of 60+ languages, detected on their own. A lecture in Arabic, Hindi, Spanish or French with English technical terms comes back with both languages written correctly.
• Revise in your own language. The summary comes in the lecture's language or the one you choose, and the transcript translates into 46 languages.
• A whole term in one place. Keep one folder per module, search every note, and ask the AI chat what a module said about a topic across every lecture.
• Seminars and supervisions too. Speaker labels separate the tutor from the students, and the bot joins online classes on Zoom, Microsoft Teams, Google Meet and Webex.
• Export to PDF, Word or plain text and build your revision document on top.

The other six

• Otter.ai records in person from its iPhone app. The free Basic plan stops each conversation at 30 minutes, which is shorter than most lectures, and gives 300 minutes a month. It transcribes 6 languages: English, Spanish, French, German, Japanese and Chinese. See Noter AI vs Otter.ai.
• Notta records on iPhone and transcribes 58 languages. The free plan stops each recording at 3 minutes. Pro allows recordings of up to 5 hours and 1,800 minutes a month, and is billed at $97.99 a year. See Noter AI vs Notta.
• Goodnotes records audio inside a handwritten note. The free plan includes 20 minutes of recording, and transcription stops after three hours. Summaries depend on the tier.
• Notability links the recording to what you write, so tapping your notes jumps the audio to that moment. Transcription starts on the Plus plan, and AI summaries need Pro.
• Coconote turns a lecture recording into notes, a transcript, quizzes and flashcards, and runs on iPhone, iPad, Android, Mac and the web. See Noter AI vs Coconote.
• Voice Memos is already on your iPhone. On iPhone 12 or later it writes a plain transcript in 10 languages, with no summary of its own, which is why many students import the recording into a second app. The steps are in how to transcribe a voice memo.

How we picked

Each app was judged on what a student needs from one lecture, and then from a whole term.

• It records a full lecture in the room, from a phone on the desk, without stopping at a short limit.
• It keeps recording with the screen locked, so the battery lasts and nothing gets tapped by accident.
• The notes are ready to revise from: a summary or bullet points on top of the transcript.
• It handles the lecture's language, including courses taught in one language with technical terms in another.
• It works across a term, with folders, search and a way to ask questions across many lectures.
• The yearly price for one student, taken from each company's own pricing page on 23 September 2026.

Bottom line

For recording lectures on iPhone and getting notes you can revise from, Noter AI covers the whole job: up to three hours per recording with the phone locked, notes in the format you pick, 60+ languages, and a term's worth of lectures you can search and question. At $69.99 a year it costs about $5.83 a month, with a free plan to try the app and a free trial on every subscription. Test it on one real lecture from your normal seat.
