Built from what you upload

Nothing here is generic.

Every guide, explanation, and quiz question is pulled from the material you actually gave it, not a general knowledge dump.

Grounded in your material

Drop in a PDF, a slide deck, or pasted notes. Guides and quizzes are built strictly from that content, if it's not in your material, it's not in the answer.

Guides that make you work

Every topic gets a concept, a worked example, and a challenge problem with the answer hidden until you're ready to check yourself.

An agent that finds the gaps

After a quiz, the agent scores every topic, picks the weakest one on its own, and keeps quizzing you on it, with more questions while there's more ground to cover, fewer as you close in.

The loop

From upload to mastered, in order.

This is the actual sequence, not a marketing metaphor: each step feeds the next one.

01

Upload your material

PDF, PPTX, images, or pasted text, indexed into a workspace for that subject.

02

Get a study guide, or take a quiz

Read a grounded guide with gated challenge questions, or jump straight into a multiple-choice quiz.

03

The agent scores every topic

Each quiz attempt updates a mastery score per topic, recent performance counts more than an old mistake.

04

It picks your next focus, you don't have to

The weakest topic gets targeted automatically, with a round sized to how much ground is actually left to cover.

Good questions

A few things you might be wondering.

Can it work with my actual course material?
Yes. Upload a syllabus, slides, PDFs, or paste notes directly. Guides, explanations, and quiz questions are built strictly from what you give it, not general knowledge about the subject.
Will it just give me answers?
No. Every topic includes a challenge problem first, with the worked answer hidden behind a "Reveal Answer" button, so you attempt it before checking yourself.
What file types are supported?
PDF, PPTX, JPG, and PNG uploads, plus pasted text. Slide images are analyzed for diagrams and code, not just their text.
Can I use it on my phone?
Yes. It runs in the browser, so it works on any device with no install.

Stop cramming. Start understanding.
