“The ability to customize width would make it 5 stars!”
“So easy and convenient. Don't know how I lived without it.”
“Good job on the v1.1.0 Update! As a full-time dark mode superuser this update addresses my only 'concern' with the app — the toolbar was very hard to read. But not any more!!! I have been using this app for months and find it to be the best in breed!!”
“아주 만족합니다.”
“A MAJOR game changer for my school work and general note taking!! When I'm revising or need to jot down a quick idea I don't have to swap to another tab/document because I can just open this extension! I AM IN LOVE!!!!”
“Simple but with so much more functionality than other notes apps I've tried! I love that I don't have to pull up another tab or window to access my notes, and I love the simplicity of the file system. Well done, thank you!!”
“This is smooth! but i hope there're updates about more themes besides black (or any black themes) because it's too dark and i literally cant see the markup icons xD”
“nvm found it! thank you smoothapp! could we possibly have a left handed button? since im left handed and all :p kthx”
“Is there any way to move this to the left?”
“I have installed literally DOZENS of note-taking extensions, and I have different ones for different purposes. This one is hands down the BEST one I have come across. It does everything that I want it to do.”
“I use this in my day-to-day life to manage tasks and quickly save meeting notes. It's an excellent product.”
“Happy to see you've added a Hide/Show Shortcut toggle for the floating purple button, since it would have been a dealbreaker for me. Having this extension pinned to the extension bar means I can pull info up in one click, right from the browser window I'm already in.”
“great！”
“BOA”
“You've done a very nice job. It's great to not have to switch out of my browser to take notes, and copying/downloading them is convenient. I also appreciate that you don't force users to create an account or to store their notes in the cloud.”
“Side Panel Notepad is a lifesaver! Writing notes while browsing is seamless, and the auto-save feature is a game-changer. Simple, secure, and free—highly recommended!”
“This is a very nice and useful idea !”
よくある質問と回答。
What happens to my notes if I cancel Pro?+
Nothing. Your local IndexedDB copy stays intact — only cloud sync pauses. Re-subscribe and everything resumes where it left off.
Do I have to sign in to use the extension?+
No. The free extension has zero network calls. Sign-in only matters if you want cloud sync, which is a Pro feature.
How is my data protected?+
Per-user Postgres rows with Row-Level Security. Auth via Supabase (Google sign-in). We store email, note content and subscription state — nothing else.
What about conflicts if I edit on two devices?+
Last-write-wins with a non-dismissing toast when another device saves while you are typing. No silent clobbering.
Can I get a copy of my notes?+
Email sunilkm2610@gmail.com from your account address and we'll send you an export of the notes we hold for you. You can also delete your account and all data in one click.
Is there a note size limit?+
Individual notes are capped at 500KB for sync reliability. You can still store larger notes locally.
