AI Note Taking App for International Students
Stop struggling with fast-paced English lectures. Record, transcribe, and review at your own pace. Built specifically for ESL and international students.
Can't keep up with your professor's fast English? Understand every lecture.
If you sit in class thinking "I can't follow my professor's fast English", you are not behind — the lecture is just moving faster than anyone can process a second language in real time. Lecsy is the app to understand English lectures for international students: it lets you keep up in the moment and catch up afterward, so a single hard word never costs you the rest of the class.
Keep up in real time
Live captions show every word on screen as your professor speaks. When you miss a phrase by ear, you read it — so you can follow the lecture instead of freezing on the word you didn't catch.
Catch up at your pace
After class, the full transcript is yours. Re-read the fast parts as slowly as you need, look up academic terms, and finally understand the sections that flew by during the lecture.
Understand in your language
Lecsy summarizes the English lecture into your native language and highlights the key points, so you grasp what the class was actually about — not just the words, but the meaning.
Then there's Exam Mode: turn any recorded lecture into study questions so you can check whether you truly understood it before the test. Free to start — 3 hours of Premium AI (high-accuracy English, live captions), then unlimited on-device English transcription, no internet needed. Not sure you're allowed to record?

Why International Students Struggle With English Lectures
The listening speed gap is real. Native English speakers process speech at 150-200 words per minute. For ESL students, processing speed is slower, especially when dealing with academic vocabulary and complex concepts. Fast-speaking professors become overwhelming.
Accents and slang add complexity. Different professors have different accents — British, Australian, regional American. Add academic jargon and casual expressions, and understanding becomes even harder.
Taking notes while listening is double the challenge. You're trying to understand English AND write notes at the same time. This cognitive load means you miss important information. Many international students report understanding only 50-70% of lecture content.
"I struggled with understanding fast professors." This is a common experience. In a 300-person lecture hall, asking professors to slow down isn't always possible. You need a solution that works for you.
"As a Japanese student studying in the US, I used to miss half of what my professor said in History 101. Even when I understood the words, I couldn't process the concepts fast enough. Lecsy changed everything — now I can focus on understanding during class and review the full transcript later at my own pace."
— International student, UC Berkeley
How AI Note Taking Transforms the Lecture Experience
Record Everything, Review at Your Pace
Instead of trying to catch every word during class, you can relax and focus on understanding concepts. Record the entire lecture, then review the transcript later when you have time to:
- Read at your own comfortable speed
- Look up unfamiliar words and phrases
- Reread difficult sections multiple times
- Take notes from the transcript, not during the lecture
Audio + Text = Better Understanding
Lecsy gives you both the audio recording and the text transcript. This combination is powerful for language learning:
- Read the transcript while listening to improve pronunciation recognition
- See how words are spelled while hearing them spoken
- Understand context better by reading and listening simultaneously
- Build vocabulary by seeing academic terms in context
AI Summary Helps Extract Key Points
Lecsy's free AI-powered summaries extract main concepts, key points, and important details — in your native language. This helps you focus on what matters most, especially when dealing with long, complex lectures in a second language.
Why Lecsy Is the Best Choice for International Students
Falls Back Offline = No SIM Card Issues
Many international students use local SIM cards or limited data plans. After your free 3 hours of Premium AI, Lecsy keeps transcribing English on-device — no internet needed. Recording is always offline. At no cost.
Privacy: Lecsy Never Stores Your Audio
Your .m4a recording file never leaves your iPhone. During the 3-hour Premium AI intro, the live audio stream goes to our speech-to-text engine for English transcription and is never stored by Lecsy. After that, transcription is fully on-device (English). We do not retain or train AI models on your data.
Simple UI, No Language Barrier
Lecsy's interface is clean and intuitive. No complex settings or confusing options. Just record, transcribe, and review — simple enough for anyone, regardless of English proficiency.

Lecsy starts with 3 hours of Premium AI (high-accuracy English, live captions), then continues for free with on-device English transcription. AI summaries in your native language and Exam Mode are included — at no cost. Pro is an optional upgrade ($9.99/mo, 7-day free trial) for more Premium AI cloud transcription. Otter charges $16.99/mo and Notta $13.99/mo.

FAQs
Does it understand accented English?
Yes! Lecsy's AI transcription handles British, Australian, Indian, and non-native English speakers well. During the 3-hour Premium AI intro, our cloud speech-to-text engine delivers high accuracy, even for non-native speakers. After those hours, the on-device tiny.en model is a bit less robust but still good for clear everyday English.
Can I review lectures in my native language?
Yes — Lecsy transcribes the English lecture, then generates the AI summary in your native language (Japanese, Spanish, French, German, Portuguese, Italian, Russian, Hindi, and more) on any plan. So you hear and read the lecture in English, but understand the key points in the language you read fastest.
Is it free for students?
Yes — Lecsy is free to start. Every new user gets 3 hours of Premium AI English transcription (high accuracy, live captions) — sign in with Apple or Google, no credit card. After those 3 hours, Lecsy continues with on-device English transcription, native-language summaries, and Exam Mode, at no cost. Pro is an optional upgrade ($9.99/mo with a 7-day free trial) for more Premium AI cloud transcription. Otter charges $16.99/mo and Notta $13.99/mo for unlimited.
How is this different from Otter.ai?
Lecsy is built specifically for students, and it's free. You get 3 hours of Premium AI English (high accuracy, live captions); after that, on-device English transcription keeps going — your iPhone handles it offline — plus native-language AI summaries and Exam Mode, all free. Otter charges $16.99/mo. Lecsy never stores audio on its servers — the .m4a file stays on your iPhone, and the live stream is never stored by Lecsy.
What if I don't understand some words in the transcript?
That's exactly why Lecsy is helpful! You can read the transcript at your own pace, look up unfamiliar words, and review difficult sections multiple times. This is much easier than trying to catch everything during a fast-paced live lecture.
Will it help if my professor talks too fast?
Yes — that's the core problem Lecsy solves. When you can't keep up with fast English in the moment, Lecsy captures every word as live captions while you listen, then keeps the full transcript so you can slow down and read at your own pace afterward. You focus on understanding the concepts during class, and catch up on the exact wording later — no more missing half the lecture because the professor moved on.
Can I read the summary in my language?
Yes. Lecsy transcribes the English lecture, then generates the AI summary in your native language — Japanese, Spanish, French, German, Portuguese, Italian, Russian, Hindi, and more — on any plan. You follow the lecture in English, but understand the key points fastest in the language you read best.
Is it legal for international students to record lectures?
In most cases yes, especially for personal study, but the rules depend on your school's policy and your state's recording-consent laws. We wrote a full guide covering when a professor's permission is needed and how to stay on the right side of the rules — read How to Record Lectures Legally at /how-to-record-lectures-legally.
Do I need internet?
No — recording is always offline, and after your free 3 hours of Premium AI, Lecsy keeps transcribing English on-device with no internet needed. Live captions and Premium AI cloud transcription do use a connection while they run, but you can record and get an offline English transcript even on a plane or with a limited data plan.
