You've got lecture slides for organic chemistry. Highlights for important reactions, notes for the lecturer's tangents, freehand circles for things you want to come back to. A good annotation workflow turns a 60-page slide deck into a study tool.
Flint gives you the tools.
Highlights for key concepts
Open annotate PDF, drop the slide deck. Use highlights for definitions, equations, key results. Yellow for general importance, red for 'will be on the exam' (your instinct), green for 'I get this'. Develop your own code and apply it consistently across your courses.
Notes for context
Sticky notes capture what the lecturer said that isn't on the slide. 'Be careful with the sign convention here' or 'this is wrong on slide 14, check the textbook'. Notes are private to your copy — paste them on top of your slides for future review.
Freehand for diagrams
Reaction mechanisms, molecular structures, anything you'd sketch in a paper notebook — sketch it on the PDF with the ink tool. Especially good on iPad with Apple Pencil. The marks stay with the slide so you have the lecture text plus your sketches in one file.
Organising by lecture
Split the full course PDF into per-lecture files for cleaner annotation. Each lecture becomes its own annotated study guide. Or merge related lectures by topic if your course covers a theme over several sessions. Pick a structure that matches how you study.
FAQ
Does it work on a school-issued Chromebook?
Yes — Flint is browser-based, no install. Works on Chromebook, Mac, Windows, iPad.
Are annotations searchable?
Text annotations and sticky notes are searchable. Highlights make the highlighted text findable. Freehand ink is not searchable.
Can I share my annotated copy?
Yes. Save and send. Annotations travel with the file.
What if I lose my Internet connection mid-annotation?
Flint runs in your browser after initial load. Work continues offline. Save before closing the tab.
