SideNotes - Quick notes on screen edge

SideNotes is a quick-access notes app that lives on the side of your screen. Always available, even in full screen. Format text with Markdown (markup stays hidden), make task lists, customize with themes and lots of settings, sync via iCloud.

Hello 👋 I’m Marcin, the maker of SideNotes. A few days ago I've launched the biggest update since version 1.0. 🎉 Version 1.5 introduces a completely new text editor that hides Markdown syntax from view. Your notes now look clean and readable, while still being Markdown under the hood. You can still type using Markdown, of course — or use the Aa menu. SideNotes is designed for taking quick notes without losing your workflow. The app lives on the side of your screen (you can choose which side). You can open it by clicking the Open Bar (a small button), using a keyboard shortcut, or simply by moving your mouse to the screen edge. It’s always available — even in full-screen apps. So whenever a thought, task, or idea pops into your mind, you can quickly jot it down, then hide the app and continue working. Or leave it open — it’s entirely up to you. The app is highly customizable. It comes with variety of settings. You can even choose a theme or create your own one. It includes automatic backups and optional iCloud sync, so your notes are accessible on iPhone or iPad via SideNotes Mobile (sold separately). I sell the app as a one-time payment, with upgrades for major versions — just like in the good old days. No subscriptions. Once you buy it, it’s yours. There is also a 40% discount on the app until August 1 as a part of 14 Years of Apptorium sale. — Marcin

@m_krzywonos Love the minimal vibe. I’m curious—does it support markdown and quick formatting, or is it plain text-first?

Marcin Krzywonos

@aqsay_sajjad Markdown! And with the latest update, the markup stays hidden (you can show it in Settings though)

This looks super sleek — love how SideNotes stays tucked to the side without getting in the way.

That said, I’m really hoping for a Windows edition someday! I usually use Sticky Notes, but they often get buried behind full-screen apps — which is frustrating during coding or design work.

Sometimes even side note apps can interrupt full-screen usage a bit. A small, always-on overlay button (like the left arrow in ASUS AI Suite) would be amazing — just something minimal on the edge of the screen to summon notes without leaving full screen.

That would seriously make it a game-changer for devs like me.

Congrats on the launch — it already feels like a super thoughtful tool! 🙌

Have been using SideNotes for over 3 years now. The most convenient note taking app for Mac.

Looks awesome! Really appreciate the markdown support!
Marcin Krzywonos

@dmitrymomot Now, you need to try themes. It will look even better :)

Hey Marcin, does it work as a stand alone app or is there a possibility to import notes from native Mac app?

Marcin Krzywonos

@busmark_w_nika It's a stand alone app. You can try to import notes using Apple Shortcuts or Apple Script. However, I'm not sure if the whole Notes contents will be correctly imported. There are some limititations on the side of the Notes app.

Upvoted! This is fabulous. Starting today, I’ve cleared all the papers from my desk. You’ve made my work so much easier!

Marcin Krzywonos

@milad_ebrahimpour That's the idea of this app! :)

Vlad Bahara

Cool idea with sleek design, love it!!

I have been feeling the need of something like this since a few months now.

@apoorv9496 I hope you enjoy the app

Congrats on the launch! Side panel notes are exactly what my messy desktop needed. Quick capture without breaking flow is a win.

Alexander Bobko

Upvoted! Do you guys have or plan to add iPhone app?

Marcin Krzywonos

@alexander_bobko1 There is an iPhone app

Any plans for a Windows version?

Tried this out and it’s actually really handy. I like how it just stays on the side without getting in the way, even in full screen. The hidden Markdown is a nice touch too — keeps things clean. Plus, the iCloud sync is super useful for switching between devices. Definitely a solid option for quick notes or to-dos.

Marcin Krzywonos

@jlopesyui Thanks and welcome aboard!

This feels like the kind of app that slips into your workflow without interrupting it. How come the EULA is not copiable though? I wanted to generate a FairPact report for it.

Yuriy

Any integration, yes, with AI? To decide what to do the first thing next morning for example?

Rena

Congrats on the big update, Marcin! Hiding Markdown syntax while keeping it editable is such a smart move — makes note-taking cleaner without sacrificing flexibility. Love the always-accessible design too. One-time pricing + iCloud sync? Big win. 👏👏

This is what I want. Thank you.
