Better grades, or we pay for your next semester.
Sylly is the most advanced AI-powered study tool ever built for university students. Instead of paying for 8 different apps, everything you need to ace your semester lives in one place.: All your courses are organized. Every due date and grade is tracked. Every lecture is recorded & transcribed. Notes, flashcards, and practice tests are generated from your specific course material. Access to a 24/7 advanced tutor that actually knows your courses. We're so sure Sylly will improve your grades, we put money on it:
If your grades don't go up, you get a full refund and next semester free. If they do, you win your money back in credit. Either way, we pay.
See the magic for yourself, the full interactive demo is free:
No card to start. 7 days to change your mind. A semester to change your grades.
This is the actual Sylly app. Try it here for free!
Below is a live demo with a sample student's semester already loaded, and every feature you just read about (due dates, notes, flashcards, the AI tutor) is in there. Click around, drag things in, and watch it build a whole semester. No account, no download, nothing to install:
Let's set up your semester.
First, the basics. This takes 10 seconds.
You don't have a studying problem.You have a chaos problem.
University gives you the classes, deadlines, lectures, readings, assignments and exams. It never gives you a system for keeping up with all of it.
So you build one yourself.
A syllabus in one tab. Deadlines in another. Lecture slides buried in the course portal. Notes somewhere else. Three reminders on your phone. An assignment you swear wasn't due until Friday.
Then suddenly it's 11:14 PM and you're searching through five PDFs just to figure out what's actually on tomorrow's quiz.
You sit down to study
and spend the first hour deciding what to study.
You rewrite notes you'll never open again. Reread the same chapter and still can't recall it. Make flashcards when you should already be reviewing them.
And little by little, everything gets pushed back.
Studying happens the night before.
The assignment gets finished the hour before.
One lecture you meant to review becomes four.
Not because you stopped caring.
Because no one ever taught you how to run a semester.
And eventually, something gets missed.
You can work harder. Buy another planner. Download another study app. Make another schedule. But none of those solve the real problem:
Your semester is fragmented across a dozen places, and you're the one holding it all together.
That's why studying feels harder than it should.
You don't need another place to put your notes. You need something that knows your courses. Knows what's due. Knows what you've covered. Knows what's coming next. And turns all of it into one system that runs with you:
That's Sylly.
No card to start. 7 days to change your mind. A semester to change your grades.
How Sylly runs your semester
The whole system, in the order it happens.
Day one
Give Sylly your syllabus and your timetable
What you do
Upload the syllabus for each class, plus a screenshot of your timetable.
What Sylly does
Builds your classes, with their days, times and rooms. Reads every syllabus and lists every quiz, test, assignment and exam, with its due date and how much of your grade it's worth. You check the list and fix anything it missed.
Every week
Sylly plans your studying for you
What you do
Press one button.
What Sylly does
Puts study sessions in your week for everything that's coming up, only in the hours you're free: never during a class, never past 9 PM, at most four in a day. Bigger tests get more sessions and start earlier. Drag a session to move it, add your own, and re-plan whenever you like.
Every lecture
Sylly takes the notes
What you do
Press record when class starts. Ask the tutor anything you didn't understand.
What Sylly does
Records the whole lecture and turns it into a transcript. Writes your notes from it, and points out anything the professor said will be on the exam. Makes flashcards from your notes and slides. The tutor has read your syllabus and your lectures, so its answers match your class.
Before every exam
Practice first, then know where you stand
What you do
Pick the lectures, notes and materials you want to be tested on. When your real marks come back, enter them.
What Sylly does
Writes a practice test from exactly those materials, grades it, and explains every answer. Shows your grade so far in every class, and what you need on the final. Tracks your Lock-In Challenge progress for you: weeks studied, exams prepared for, your streak.
Do that all semester, and we'll back it with our own money.
THE SYLLY FALL SEMESTER LOCK-IN CHALLENGE:
Finish the semester. Get rewarded.
Use Sylly all semester, and we pay you back either way — as credit if your grades go up, in full if they don't. First 500 students only.
Why we'd do that: Sylly works, but only if you keep using it past week three. Nothing makes someone stick with a tool like having money on it. So we're paying for your accountability, because we want as many students as possible to find out what a semester feels like from the other side — better grades, fewer hours studying, actual sleep.
What a founding seat gets you
- Your price never goes up — what you join at is yours for as long as you stay
- The three grade guarantees below. They come with the seat, not the product
- A live tracker in the app, so you always know if you're on pace
- A founding number, 1 to 500 — how we know who was here first
What “do the work” means
Use Sylly about three times a week, in most weeks — not every week — touching at least three of its five tools those weeks (lecture recording, flashcards, practice tests, notes, AI tutor), and study with it before your big exams. Sylly counts all of it for you: nothing to log, nothing to prove in December, and you can see where you stand any day. Miss a few weeks entirely and you're still fine. Full rules.
Only 500 founding seats available
Doors close when seat 500 fills, or October 31 at 11:59 PM ET — whichever comes first. The challenge is measured in weeks, so joining in November leaves too little semester to finish one. After that you can still get Sylly and the 7-Day Promise, just not the founding seat or the grade guarantees.
We bet on your grades.
One bet, two outcomes. We pay on both.
The 7-Day Promise
Change your mind in the first week. Everything back, no questions, no forms.
The Better-Grades Promise
If your grades don't go up: do the work and you get a full refund, you keep everything you made, and your next semester is free.
The Pass-Every-Class Promise
First year? You have no last semester to beat, so this is your version of the bet: do the work and pass every class you run through Sylly, or your money back.
Win Your Money Back
If your grades do go up: do the work and you get your money back as credit toward next semester. This and the Better-Grades Promise are one bet pointed two ways.
FROM THE FOUNDER
I built Sylly because my own semesters were chaos. Five classes, five syllabi, deadlines buried in PDFs I never opened twice. I wasn't failing because I was lazy, I was drowning because nothing lived in one place.
So I built the system I needed: drop in the syllabi, get a plan, follow it. It's the tool I use myself, and I'm betting the company on it working for you. That's also why there's a bar to clear at all — I'm not going to promise results to someone who never opened the app. But do the work, and if Sylly doesn't move your grades, I'd rather give the money back than keep it.
