Lecture notes to video
You have the notes. You still don't know what the lecture meant.
That gap is normal, and it isn't a sign you're bad at this. Notes are a record of what got covered. They're not an explanation. When you write "Phase 1: light-dependent reactions" in your notebook, you're recording a label. The part that would have made it make sense was something your lecturer said out loud for ninety seconds while you were writing.
Nobody wrote that part down. Not you, not the lecturer.
What this does
You upload your notes. Lecturly reads them, works out what the topics are, and builds a short video lesson for the topic you pick.
The video is narrated the whole way through, and the visuals are built to match what's being said. It's not a slideshow with a robot reading your bullet points. It's an explanation of the thing your notes are pointing at, in about four minutes.
You also get three other things off the same file, and you don't have to make a video first to use them:
- A one-page study sheet with the key terms and the mistakes people make
- A flashcard deck with progress tracking
- A practice quiz that grades you as you go
How it works
- Upload. PDF, PowerPoint, or Word. Handwritten notes need to be typed up or scanned as text first.
- Pick a topic. Most lecture notes cover four or five separate ideas. Lecturly splits them up so you can do one at a time instead of sitting through everything.
- Watch. Around four minutes. There are captions, chapter markers, and you can scrub back.
- Ask. If something in the video doesn't land, there's a chat next to it that knows where you are in the lesson. You can just ask.
What it's good at
Notes with real content in them. Full sentences, worked examples, definitions, diagrams with labels. The more there is to work with, the better the explanation.
Topics you sort of get but couldn't explain. That halfway state where you'd recognise the right answer but couldn't produce it. Hearing it explained start to finish usually fixes that faster than rereading.
Catching up fast. If you're three lectures behind, four minutes each is a realistic way back in. Rereading three weeks of notes is not.
What it isn't good at
I'd rather tell you now than have you sign up and find out.
Notes that are five words per slide. If your notes say "Krebs cycle" and nothing else, there's nothing in the file to explain. Lecturly won't invent a lecture that wasn't there. Use the textbook chapter instead, then come back.
Maths-heavy derivations. It handles formulas fine when they're explained in the source. It's weaker at long step-by-step proofs than a person at a whiteboard.
Pure memorisation. If you already understand the material and just need to drill it into your head, a video is the slow way to do that. Use the flashcards, or honestly, use Anki. Drilling is what it's built for and it's better at it than we are.
Handwritten photos. Not yet.
Why a video and not a summary
Most study tools summarise. Summarising makes text shorter, which is useful when you have too much text.
That's not the problem here. Your notes aren't too long. They're missing the explanation. Cutting them down gives you a shorter version of the same gap.
There's also a trap in summaries that's worth knowing about. Reading a clean summary feels like learning, because it reads smoothly. Smooth reading gets mistaken for understanding. You close the tab feeling ready and then find out in the exam that you weren't. Researchers call this the fluency illusion, and it's one of the most consistent findings in study research.
An explanation you have to follow is harder to fake your way through than a summary you skim.
Getting started
Three lessons free, no card. That's enough to try it on a real lecture and see whether it works for your course, which is the only test that matters.
The study sheets, flashcards and quizzes work without making a video at all, so you can also just upload your notes and go straight to those.
