Postik
Pin notes, flags and stickers to any app, web page or chat — right on the line you choose. Scroll away and they step aside; one click brings you right back.
Nine short steps. Use the arrows, the list, or your keyboard (← →).
Sticky notes
Jot down an idea and stick it anywhere on your screen. Six classic paper colors, a handwritten feel and a red pushpin to keep it right where you want it.

📌 Pin herePin a note to the page you’re reading: it shows up only on that tab and steps aside when you switch. Flags and stickers work on web pages too — in Safari, Chrome, Arc, Edge, Brave and more.
Page flags
Clip a flag onto any line of text. When it scrolls out of sight it waits at the edge of the screen — one click and you’re back at your mark, even in another chat. Like a GPS for long chats and documents.
Put a sticker on any spot of the content. It follows that text as you scroll and quietly hides when it’s out of view. Import your own images to make them truly yours.
Pin notes and flags to a single conversation in ChatGPT, Claude and your other chat apps. They show up only in that chat, and “Go to” takes you back to it — right at your message.
Does your app do things its own way? Show Postik once where everything is. It takes a minute, and you only do it once.
Every note, flag and sticker stays glued to its spot — while you scroll, resize the window or move to another screen. And all of it stays on your computer.
Stack related notes, move them together and open them full screen.
Colors, bold, underline, fonts and sizes — with handy keyboard shortcuts.
Record a voice memo or attach a file right inside a note.
Mark spots in long notes with little colored bookmarks.
The menu lists every note by where it lives, and “Go to” takes you straight there.
Each note stays with its app, on the right monitor — even in full screen.
No account, no cloud, no tracking. Your notes never leave your computer.
A tiny native app that barely touches your memory or battery.
English, Español and 日本語 — with a handwritten look, even in Japanese.
