Free study tools that do the busywork for you
Flashcards, summaries and worked answers, made from the PDFs and slides you already have. The hour you were going to spend retyping your notes goes into learning them instead.
Tools
PDF to text Pull the text out of a textbook, paper or handout. Keeps page order. PowerPoint to text Every slide as plain text, including the speaker notes. PDF to flashcards Turn a chapter into a deck, then export to Anki or Quizlet. Study calculators Chemistry, physics, maths and grades — each solves for whichever value you leave blank.
Want this everywhere, not just on this page?
StudyFrame is a Chrome extension. Snip any question on any site and get the answer in place — plus summaries, flashcards and practice tests.
Free to install. 3 uses a day at no cost, more if you study on a streak.
Why these are free
They cost nothing to run. The work happens on your computer, so serving one person and serving a hundred thousand costs the same — which is nothing. The extension is the paid product, and only once you have used the free tier enough to want more of it.
