How It Works

From a PDF on your phone to a habit you keep.

One upload turns into every study tool BILKEYS has. Here's exactly what happens between dropping in a book and reviewing it a month later.

Step 1
Upload a book
Step 2
We find the chapters
Step 3
Pick a lab
Step 4
Study until it sticks

The four steps

Step 1
Upload once

Drop in a PDF. BILKEYS finds the chapters automatically, so there's nothing to organize by hand.

Step 2
Choose a lab per chapter

Each chapter can become flashcards, a Chapter Brief, Scenario Lab problems, or Diagram Lab illustrations, or all of them.

Step 3
Review until it sticks

Daily review, timed games, streaks and XP keep what you learned from fading a week later.
