A typical study session

Most students figure it out inside one lecture. Here is what that looks like.

Hotkey during lecture

Ctrl + Shift + P brings up the toolbar over Zoom, Teams, or whatever the prof is sharing. Annotate without leaving the call.

Highlight the formula she just wrote

Highlighter or pen, your color. Then screenshot the marked-up slide straight into your notes folder for review later.

Whiteboard for working out a problem

Press W (or click Whiteboard in the toolbar). Clean canvas to derive a formula or sketch a diagram. One press to dismiss back to the slide.

Mark up your PDF reading

Open the PDF in your usual reader, hit the hotkey, circle the key argument, screenshot. Build a study deck of marked-up screenshots.

What this is, and what your notes app should still do

HoverScribble does not replace OneNote, Notion, or Obsidian. It is a markup overlay. Use it together with whatever you already use for primary notes.

Use HoverScribble for

Live annotation on the professor's shared slide
Marking up PDFs without permanent edits
Working out math problems on a quick whiteboard
Highlighting key terms in a YouTube tutorial
Capturing annotated screenshots for study decks

Keep using your notes app for

Spaced repetition flashcards (Anki)

Where it pays off most

The subjects and study modes where HoverScribble gets used the most.

Math & physics

Derive on a whiteboard, mid-lecture

Whiteboard mode for working out a derivation while the prof's slide is still visible behind it. Save the working as a screenshot for your problem set.

Biology & medicine

Mark up anatomy and diagrams

Annotate cell diagrams, anatomical figures, or histology slides during lectures. Color-coded pens for systems, layers, or pathways.

Languages & humanities

Annotate readings without ruining the PDF

Highlight passages, scribble translations, mark up rhetorical structure. Screenshot when done. Original PDF stays clean.

CS & engineering

Trace through code on screen

Draw arrows through pointer chains, highlight variables across a function, sketch state diagrams over the diagram in the slide.

Self-study

Mark up Khan Academy / YouTube tutorials

Pause the video, hit the hotkey, circle the part you don't get. Screenshot it for the question you'll ask the TA tomorrow.

Group study

Explain a problem on a screen-share

Discord or Zoom screen share with friends, hotkey, draw the explanation. Same workflow as your professor uses to teach you.

Works with everything you already study with

HoverScribble draws on top, so any of these apps just see the annotation on the screen. No plugin, no setup.

Student questions

Is HoverScribble useful for students without a tablet or stylus?

Yes. HoverScribble works fine with just a mouse or trackpad. Pressure sensitivity is a bonus if you have a Surface, Wacom, XP-Pen, or Huion device, but it is not required. Plenty of students use it on regular laptops to highlight text, circle key terms, and work out problems on a whiteboard.

Can I save my annotated lecture slides?

Yes. Use the screenshot tool to capture your annotated screen as a PNG. For multi-page captures of long lecture decks, use Story Mode. Save the images to your notes folder, OneNote, Notion, or anywhere else.

Does HoverScribble work over Zoom and Microsoft Teams lectures?

Yes. HoverScribble draws a transparent overlay on top of any application, including Zoom, Microsoft Teams, Google Meet, and Webex. Annotate the professor's shared slide right on your screen as the lecture happens.

Is there a student discount?

HoverScribble is already a one-time $18 payment with lifetime updates and a 7-day free trial with every feature unlocked. There is no separate student tier, but $18 once is intentionally below most student software budgets and there is no recurring charge.

Should I use HoverScribble or OneNote / Notion for note-taking?

Use both. OneNote and Notion are your primary notebook. HoverScribble is a screen-overlay markup tool: best for live annotation on top of slides and PDFs, working out math problems on a quick whiteboard, and capturing screenshots of marked-up content. Save those screenshots into OneNote or Notion.
