## What is Lecsy?

Lecsy turns any English lecture into clean, searchable notes — automatically.

Hit record at the start of class. Walk out with a full transcript, an AI summary, and a set of likely exam questions. For university students tired of retyping notes at midnight.

Free to download. Sign in and get 3 hours of Premium AI English transcription, free — no credit card. Want more cloud transcription? Lecsy Pro is optional. The Free tier stays free.

■ Made for students, not meeting rooms
• One-tap background recording — keeps running when your screen locks or you switch apps
• 3 hours of Premium AI English transcription, free — high accuracy with live captions (join the waitlist for 5 more)
• After your premium hours: unlimited offline English transcription on device (WhisperKit) — works in lecture halls with no Wi-Fi
• AI summaries: key points, section outlines, definitions
• Exam Mode: AI generates likely test questions with model answers
• Summaries in your native language — record the English lecture, read the summary in 9 languages (English, Japanese, Spanish, French, German, Portuguese, Italian, Russian, Hindi)
• Web access at lecsy.app — read, search, and copy transcripts on any laptop

■ Lecsy Pro (optional)
20 hours of premium cloud transcription per month — high-accuracy English captions. After that, transcription continues on your device (offline, unlimited).

• The Free tier remains fully usable without Pro
• Cancel anytime in your Apple ID settings

■ Privacy you can verify
Your .m4a recording file is never stored by Lecsy — it stays on your iPhone, never saved to your account or our servers. For transcription, audio is handled two ways: during Premium AI and Pro cloud transcription, audio is sent over TLS to our speech-to-text provider, transcribed, and not stored by Lecsy; otherwise transcription runs entirely on your iPhone and audio never leaves your device. Transcript text syncs to your account only when you're signed in. Using AI Summary or Exam Mode sends your transcript text (not audio) to our server and to OpenAI's API to generate results; OpenAI does not train on API content. No ads, no trackers, no IDFA. We never sell your data, and our providers do not train on it per their API terms.

■ Who Lecsy is for
• International students in English-taught classes — keep up with fast lectures, then read AI summaries in your first language
• Undergrads who can't keep up with fast-talking professors
• STEM, pre-med, pre-law, and grad students prepping for exams from recorded classes

■ Pricing
• Free to download: 3 hours of Premium AI (plus 5 more via the waitlist), then unlimited offline English transcription.
• Lecsy Pro — $9.99/month auto-renewable subscription, 7-day free trial. Optional.
• No ads. No trackers. No data sold.

■ Requirements
iOS 17.6+. On-device speech model (~75 MB) is bundled — no download. Premium AI / Pro cloud transcription and AI features require internet (audio not stored by Lecsy); otherwise English transcription works offline. Sign-in required (Apple, Google, or magic link).

### 5/5 — Amazing app

*2026-03-30*

This is so easy to use it and keep the lecture.

### 2/5 — Glitchy

*2026-03-19*

Received a phone call and declined it during a recording and lost my recording. Locked my phone and reopened the app and lost my recording. It doesn’t automatically save anything, you have to manually save it so if it glitches then you lose the recording. 

No way to take notes after the fact. Transcription isn’t the greatest especially for someone with a non-American accent. 

Super bare bones and hardly works unless you have the app open the whole time, don’t lock your phone, and don’t receive any phone calls. 

No way to contact support or report a bug/glitch, hence this review instead of emailing the dev. 

However the app is very new and has potential that’s why it gets 2 stars and not just 1. I may revisit this app later to see if it has improved.

**Developer response:** Thank you for your detailed feedback — we really appreciate it.

We’re sorry about the recording loss issue. We are currently working on improving auto-save and making recordings more stable, even during interruptions like phone calls or app backgrounding.

We’re also actively improving transcription quality and overall reliability. Since this app is still in an early stage, feedback like yours helps us a lot.

We hope you’ll give it another try in the future 🙏

## Frequently asked questions about Lecsy

Lecsy is specifically tuned for distant speakers and can boost audio by up to +21 dB before transcription, ensuring clarity even from the back of a large hall.

### 1.29 — 2026-06-27

Critical bug fix. In version 1.28, recordings could be hidden from the in-app Library in certain sign-in/session states (the data was never deleted — it remained on device). This update restores them to the Library and also exposes recordings in the Files app so users can always access their audio. No new features; please expedite as this affects users' access to their own data.
