How to Highlight Effectively for Study
Highlighting is the most popular study technique and one of the weakest on its own. These pages show how to make it earn its place: select less, mean something by each colour, and use the marks afterwards.
The research on highlighting has been consistent for fifty years: marking text while you read does little for memory, and marking too much can hurt. But the same research shows the conditions under which highlighting helps, and they are learnable in an afternoon. This section is built on that evidence and cites it.

Does highlighting help you learn? is the honest summary of the findings. The colour code system gives you three colours with fixed meanings that work on paper, in PDFs and on the web. Turning highlights into notes is the method that makes the marks pay off, and highlighting for teachers turns all of it into classroom activities that need no student accounts.
Teachers and librarians were the original tool's largest audience. These pages are written with them in mind as much as students, and every technique works with the free tools on this site or with a pen.
The pages are short on purpose and each ends with common questions and a sources list. If you read only one, read the review of the evidence; if you do only one thing differently afterwards, read a section to the end before you mark anything in it. That habit alone fixes most highlighting.
A practical order for a new term: read the evidence page first so you know why the rules exist, set up the three colours before your first reading, and try the notes method on one chapter before deciding whether it suits you. Teachers can run the classroom activities in a single lesson with printed text and pens, then repeat them on screen with the bookmarklet once students have the habit. Nothing on these pages asks for a sign up, a download or a subscription, and nothing you highlight with our tools is ever sent to us.
Two newer pages apply the same skills to a current problem. Close reading for AI writing patterns shows what to mark when prose feels smooth but empty, and says plainly what the marks cannot prove. Authorship review with highlights gives teachers and students a fair, process-first way to talk about who wrote a piece of work.
Which page for which situation. If you have a chapter to learn by next week, read the four-pass method from highlights to spaced self-testing and follow its worked example. If your pages come back solid yellow, the rule on how much to highlight in the colour code guide is the fix, and it is a single number. If you teach, the one-line rule activity takes one lesson and needs nothing but printed text. If you are reviewing a piece of writing and want to be fair to its author, the authorship review page comes before anything else, because it sets the order: process first, style last. The section leaves out two things by design: memorisation tricks that have no research behind them, and any advice that depends on a particular app.
The study skills here also produce evidence. Highlights and notes made while reading show what a student read, which sources they used and what they took from each one, which is the subject of the record lane, where reading notes become evidence. Nothing there asks you to study differently; it asks you to keep what you already make, with a date and a source attached. Two of its pages continue this section directly. Drafting an annotated bibliography entry from the marks you already made turns reading notes into a graded document, and the workflow for verifying a source with a log and a link per claim is the research-skills counterpart to the note-making method.
How this connects to the record section: study highlights are also evidence of authorship, because they show what you read before you wrote. A reading log kept as evidence of reading is the simplest version of that record, and the authorship evidence a student can show when asked to prove they did not use AI explains how highlights, notes and drafts answer that question calmly, without relying on a detector.
Tools for marking and sharing
Both are free and store nothing: the highlight link generator and the bookmarklet.
