Feature · Invisible Notes
Notes on your screen.
Invisible to everyone else.
Sticky notes that float above every app, stay with you across desktops, and never show up on screen sharing. Write on them, style them, move them, hide them with one key. Nobody on your call will ever know they exist.
Small notes, a lot of control
Put them exactly where you want
Drop a note anywhere on screen, drag it around, and resize it from any corner. They stay on top of every app and follow you across Spaces and full-screen workspaces.
Format the text freely
Bold, italic, underline, and text size from tiny to large. A small toolbar appears right on the note, so a formula or a key phrase can stand out at a glance.
Duplicate in a click
Made a note with the layout you like? Duplicate it and just swap the content. Building a set of notes for a topic takes seconds, not minutes.
Colors that help you read
Pick a color per note. Group topics by color, or just choose whatever reads best against your wallpaper. Small thing, big difference when you glance over mid-task.
One shortcut to show or hide
A single hotkey toggles every note at once. Need a clear screen for a moment? Hide them. Need your notes back? Same key, and they return exactly where they were.
Invisible on screen sharing
Notes share the same invisibility layer as the rest of Hidini. Zoom, Meet, Teams, Discord, OBS: none of them can capture the notes, no matter how many you have open.
Learn with your notes in view
The fastest way to remember something is to keep bumping into it. Pin the formula you keep forgetting, the definition you mix up, the vocabulary you are drilling this week. Your notes sit at the edge of your screen while you work, and every glance is one more repetition.
In the video above, that is exactly what is happening: JavaScript closures on one note, call stack order on another. Studying for an exam or picking up a new stack works the same way. Write a note per concept, color them by topic, and hide them all with one key when you want to test yourself.
Keep your footing in interviews
Interviews have a way of emptying your head the moment the call starts. Notes give you a quiet safety net. Your STAR stories, the numbers from your last project, the questions you want to ask at the end. All of it stays in front of you, and none of it appears on the shared screen.
They also work as a way to keep yourself grounded. A note that just says "slow down" or "breathe, then answer" sounds silly until the pressure spikes and it is the one thing on screen that keeps you steady. Nobody sees it but you, which is rather the point.
Common questions
Can other people see my notes when I share my screen?
No. Notes sit on Hidini's invisibility layer, which operates below the screen capture level on macOS. Screen sharing and recording tools like Zoom, Google Meet, Microsoft Teams, Discord, and OBS cannot capture them.
How many notes can I create?
As many as you need. Each one can be moved, resized, colored, and formatted on its own, and all of them toggle together with one shortcut.
Can I format the text inside a note?
Yes. Each note has its own formatting toolbar with bold, italic, underline, and text size. You can also duplicate a note to reuse its layout and change the note color for better readability.
Do notes survive a restart?
They do. Notes come back exactly where you left them, with their content, size, color, and formatting intact.
Do the notes follow me across desktops and full-screen apps?
Yes. Notes stay with you across Spaces and full-screen workspaces, so they are always in view when you need them.
