AI-Powered Simplification
Turn Any Textbook or Lecture Into Notes You'll Actually Study From
Retardify is an academic note generator that reads your PDFs, textbooks, and lecture files, then rewrites the dense parts into plain-language notes organized the way your brain actually retains information.

Features
Everything you need
Handles Real Course Materials
Upload scanned textbook chapters, lecture slide decks, or recorded lecture transcripts directly—no reformatting or retyping needed before it can process your files.
Keeps Definitions and Terminology Intact
Simplifies explanations without swapping out the exact terms your professor uses on exams, so your notes still match what's tested.
Your Files Stay Yours
Uploaded documents are processed to generate your notes and aren't used to train models or shared, so course readings and unpublished lecture recordings stay private.
How It Works
From input to plain English
Upload the source
Drop in a textbook PDF, scanned chapter, slide deck, or lecture audio/transcript file in the formats you already have on hand.
Choose your note style
Pick a format—outline, summary, or Q&A flashcard-style—based on whether you're skimming, reviewing, or cramming before a test.
Get structured notes back
Retardify returns simplified notes with headers, key terms bolded, and a plain-language explanation under each concept, ready to study from immediately.
Why Retardify
Built for clarity
Less time decoding, more time learning
Dense academic phrasing gets rewritten in plain language, so you spend study time understanding concepts instead of re-reading the same paragraph.
Consistent structure across every subject
Whether it's a biology textbook or a history lecture, notes come out in the same organized format, so review habits carry across all your classes.
Overview
An academic note generator like Retardify exists for one specific problem: course material is often written or recorded in a way that's technically accurate but hard to study from. Textbook chapters bury key definitions in long paragraphs, and lecture recordings mix important points with tangents and filler. Retardify takes those raw sources and restructures them into notes organized around what you're actually expected to know.
This is built for students who are short on time between classes, working through dense reading assignments, or trying to catch up after missing a lecture. It works whether your source is a PDF textbook chapter, a scanned reading, a slide deck, or a lecture transcript—the output format stays consistent so you're not relearning how to study every time you switch subjects.
What sets an academic note generator apart from generic AI summarizers is the focus on retaining exam-relevant terminology while simplifying the explanation around it. A general summary tool might shorten text and accidentally cut definitions you need; Retardify is designed to keep those intact while making the surrounding explanation easier to follow.
Used well, it's not a replacement for reading or attending lecture—it's a way to convert material you've already been assigned into a format you'll return to when it's time to actually review and retain it.
