Prepello

Your AI doesn't know your course. One click fixes that.

Prepello turns your live Canvas course into a clean folder you own and your AI understands. Drag it into Claude or ChatGPT and ask anything: the answers come back grounded in your course, in its own words.

Free. No account, no email. Your course content never leaves your computer.

"Why does the normal distribution matter?"

Any AI, on its own

It's one of the most important concepts in statistics: many natural phenomena follow it, and it underpins hypothesis testing and confidence intervals. Understanding it will help you in science, business and beyond.

The same AI, with your course

In your course, three reasons: it's a listed learning outcome for 2101ABC; the Week 6 exam brief says Section B draws mostly on Weeks 4 and 5, which centre on it; and 3302XYZ's outline names it as assumed knowledge for next trimester. Worth getting solid this week.

The course is invented. The difference is the point.

Inside the Smart zip
  • README.md ← the only file written for you
  • AGENTS.md instructions your AI reads
  • manifest.json the map it follows
  • 2101ABC/
    • 2101ABC__W05__lecture-slides.pdf
    • 2101ABC__W05__reading-guide.md
    • 2101ABC__W05__tutorial-worksheet.pdf
  • 3302XYZ/
    • 3302XYZ__W05__lecture-notes.md
    • 3302XYZ__W05__case-study.pdf

Drag the whole folder in. The README is the only file written for you.

It knows what is due
  • 2101ABC Case report brief due Fri, Week 6
  • 2101ABC Mid-trimester exam, Section B Week 6
  • 3302XYZ Online quiz 2 due Mon, Week 7

Assignment briefs and due dates ride every export, straight from your course site.

Your degree, one zip
2101ABC 12 weeks · 84 files
3302XYZ 12 weeks · 61 files
1105DEF 12 weeks · 47 files
2207GHI 12 weeks · 73 files

One week, a whole term, or every course you have scanned. Your AI sees across all of it at once.

  • Knows what is due. Assignment briefs and due dates ride every export, so "what should I start this weekend?" gets a straight answer.
  • Sees your degree whole. One week, a whole term, or every course you have scanned, in one zip.
  • Zero setup. The folder carries its own instructions and map, so your AI knows how to use it. Drag, drop, ask.

How it works

  1. Add Prepello to your browser

    One install from the Chrome store. Nothing to sign up for, nothing to set up.

  2. Scan your course

    Open Prepello while you are logged into Canvas. It builds a week-by-week map of your course and pulls the pages and files into your browser's own storage. Rerun it whenever a new week lands.

  3. Click Export week

    One zip lands in your Downloads: a folder per course, this week's material inside. Drag the whole thing into your AI and ask it anything.

Two ways to take it

Pick at the moment you download. Smart is the default.

Smart download · the default

For your AI

One folder per course, with a plain README and a set of instructions written for the AI sitting at the top. You do not need to open any of it. Unzip it, drag the whole folder into Claude or ChatGPT, and ask your first question.

Plain files

For you

Ordinary folders, one per week. Original filenames, files untouched, the same bytes Canvas would have handed you. For keeping, printing, or reading the normal way.

Either format goes as wide as you want: one week, a whole term, a whole course, or your entire degree in one zip.

It tells you what it could not reach.

Some things in Canvas are locked, restricted, or live inside a tool Prepello cannot read. When that happens your export says so, by name, in a list. Nothing is invented and nothing goes quietly missing.

If you cannot trust the data, none of the rest matters.

What it never does

  • Never writes to Canvas. Read-only. It never posts, submits, or changes anything on your course site.
  • Never asks for an account. No sign-up, no password, no email address.
  • Never uploads your course content. The scan and the export both run in your browser, on your own computer. There is no server holding your files, so there is nothing to pool, leak, or train on.
  • Never costs anything. No ads, no trial, nothing to buy.
  • Built for prep, not answers. It puts your own course material in your hands before class. It does not write anything, answer anything, or touch what you hand in.
  • Sends numbers, never content. Anonymous usage counts, so we can see which parts get used. Never your course content, and one switch in Settings turns it off. The privacy policy lists exactly what is sent.
Coming soon

It gets better from here.

AI keeps getting better at explaining, quizzing and drilling you on anything. Prepello's job is handing it your course, so every upgrade to the tools is an upgrade to this. And the exporter is just the start:

  • Straight into your tools. One click that hands your course to Claude, ChatGPT or NotebookLM directly. No zip, no unzipping, no dragging: your export, already open in the tool you use.
  • More campuses. Prepello reads Canvas at one university today. Next come more universities and more platforms, until any course can be handed back to its student.

Who made this

Prepello was built by a university student who wanted this and could not find it. Every version gets used on a real course, in a real week, before anyone else sees it.

If a scan misses something or anything breaks, hello@prepello.app reaches a person.

Questions, answered plainly

Is this allowed?

Prepello is read-only on Canvas and on your lecture recordings: it never posts, submits or changes anything. It reads the same pages, files and transcripts you can already see, on your own logged-in session, and keeps them on your own computer for your own study.

Does it work at my university?

Today it reads Learning@Griffith (Canvas), plus the Echo360 lecture service your courses link to. More campuses are next. The extension can only ever see the sites named in its permissions, and nothing else you browse.

Which AI can I use it with?

Anything that accepts files: Claude, ChatGPT, NotebookLM, or whatever arrives next. The Smart download carries its own instructions, so there is nothing to configure.

Is it really free?

Yes. No ads, no trial, no account, nothing to buy.

What does it miss?

Anything Canvas locks or hides: restricted files, some external tools. When something cannot be reached, the export names it in a list rather than leaving a quiet hole.
