Record
Start before class and lock your phone. Penlit transcribes as it goes. You can also add photos of the board, slides, audio files or pasted text.
For students, on iPhone
Every lecture, highlighted.
Record your class. Penlit writes clear notes, flashcards and a quiz — and marks the moments your professor says will be on the exam.

How it works
From the lecture hall to a page you can study.
Read your notes
A summary, key terms and the exam signals, each linked to the exact passage of the transcript.
Remember it
Flashcards come back just before you forget them, and quizzes explain every answer.
What makes Penlit different
It hears what counts.
Professors say it out loud: “this will be on the exam”, “expect a question on this”. Penlit picks up these moments and puts them at the top of your notes, with the professor’s own words.
“Rent control is my favourite question, so expect it.”
Exam signal · quoted from the transcript, part 2- Each signal links to the passage where it was said
- Signals become cards and quiz questions first
- Nothing is invented: no quote without a source

FAQ
Questions
Am I allowed to record my class?
Ask your professor first and follow your school’s rules. Penlit asks you to confirm it before the first recording in each subject and can prepare the email for you. Your own voice or audio you have the right to use needs no permission.
Does it keep recording when my phone is locked?
Yes. Start recording, then lock your phone. A phone call pauses the recording and you can resume it.
How accurate are the notes?
They are written by AI from the recording, so they can contain mistakes. Every exam signal and every answer links to the passage it comes from, so you can check it in a tap.
Is there an Android or web version?
Not yet. Penlit is available for iPhone.
