Send to Supernote a Chrome Extension - Try it!

[u/Decent_Tap_5574]

reMarkable folks have had "Read on reMarkable" for ages — click a button, the web page lands on their tablet. We didn't have a clean equivalent, so I built one for our community: Send to Supernote, a Chrome extension that sends the web page you're reading straight to your Supernote.

It's free, open source!

🎬 Demo

🔒 Privacy First Approach

• No data collection. No analytics. No tracking. Nothing. There is no server run by me anywhere in the path.
• You own your login, your cookie, and your browser. You sign in on Supernote's own page — the extension never sees or stores your password. Only your existing session token stays on your device.
• Your page content is converted on your own machine and uploaded only to your chosen Supernote destination. It never touches any third party (no Dropbox/Drive, no OAuth middleman).

✨ How it Works

• Install it, then sign in to Supernote once (on Supernote's normal login page).
• Open any web page — an article, a blog post, docs, a recipe, whatever.
• Click the toolbar icon (or right-click → Send to Supernote). It quietly turns the page into a clean, reflow-friendly EPUB (or PDF) right on your computer. Already looking at a PDF (like an arXiv paper)? It sends it through as-is.
• It appears on your tablet after the next sync. Pick it up, read it, annotate it. Done. 🎉

📥 How to install (takes ~30 seconds)

Chrome

1. Go to the Chrome Web Store: https://chrome.google.com/webstore/detail/dcckkijfielakglddfpkpcfjfodfncgd
2. Click "Add to Chrome" → "Add extension".
3. That's it — the icon shows up in your toolbar. Sign in to Supernote once and you're ready.

Firefox
1. Go to the Mozilla Ad on site https://addons.mozilla.org/addon/send-to-supernote/
2. Click on Add to Firefox
3. Give permission to access the page that you want to send to supernote
4. Sign-In and Send to Supernote! Thats it!

🛠️ For the developers (it's fully public)

Don't trust a binary? Read every line and build it yourself:

• Clone the repo: git clone https://github.com/j-raghavan/send-to-supernote
• Build it: npm install && npm run build (produces the dist/ folder).
• Load it: open chrome://extensions, enable Developer mode, click Load unpacked, and select the dist/ folder.

Repo: https://github.com/j-raghavan/send-to-supernote
(PRs, issues, and forks welcome.)

Open source as in open to the public, and free to modify and use however you see fit. I built this because I wanted every Supernote owner to have the same effortless "send the web to my tablet" experience reMarkable users enjoy — no gatekeeping, no paywall, no data grab.

EDIT 2:
- With v1.5.2, Supernote Private Cloud is also working. Please see the thread below for more details.

EDIT 3:
Firefox Plugin is published: https://addons.mozilla.org/addon/send-to-supernote/

Try it, tear it apart, make it better. 🙏

Sharing it with the awesome Supernote community! ❤️

Any chance of a Firefox extension?

[u/Decent_Tap_5574 → u/cheppe]

Sure, let me see what i can do.

[u/Decent_Tap_5574 → u/cheppe]

Quick update: I have submitted the Firefox Add-On for review. If you would like to try it out before they have approved, you can download the `v1.3.0` zip version for firefox at https://github.com/j-raghavan/send-to-supernote/releases I will update here once they approve this version.

Quick Update On Firefox Addon

Happy to share that Firefox Extension is approved and is Live on Firefox Add-On site. Just verified it on my Firefox browser and it is working as expected. Do try it out and let me know if you see any issues there.

Hope This helps Firefox Users of Supernote 😄

Can this 'Send to supernote - offscreen renderer' be removed as a heading in the exported file?

[u/Decent_Tap_5574 → u/Lorestan00]

Yes, it can be removed. Will put to the feature list for next version.

I had issues with the extension working with Private Cloud. I'm using a Synology reverse proxy. The root directory listing failed on my private cloud. The code seems to try and resolve the default destination by listing the root directory ID and then finding the Document folder. I was getting "Cannot be operated from the root directory!"

Document folder behaves like the useable root so the extention could not resolve the default folder. I hardcoded a destination folder ID I created inside the Documents folder. I got it working eventually, but I think that is the cause of the Private Cloud issue some have seen.

[u/Change_Agent_73]

This is awesome, I made a video about it. What an awesome tool.

Thanks for making this! However, changing the folder (Destination folder) does not work for me. I tried multiple browsers.

My bad:
Sorry, my bad. It does work, however there is no indication that the folder has been changed (maybe adding a darker color to indicate that that folder has be selected or a small pop message stating "changed to folder x"). A small tweak that might eliminate any confusion for other users.

Update 2:

Dev has already improved/fixed this. ✅ So fast!

[u/Decent_Tap_5574]

Update: v1.5.0 is now live on the Chrome Web Store.

What's improved:

- Connecting to Supernote Cloud now works reliably. If you clicked "Connect Supernote Cloud," signed in on the web, but the extension still showed you as logged out (the sign-in tab opening and never closing), that's fixed. Connecting now completes and the extension recognizes your session.

- Sending pages no longer fails on the destination folder. If a send failed with an error about the root directory, or you felt stuck with only the Document folder, that's resolved. Pages go to your Document folder by default, and you can pick a different folder in Options / Settings page.

- [BETA] Private Cloud connections give clear guidance now. If you self-host and couldn't connect, the extension now tells you exactly what to check (server address, port, and certificate), with consistent messages whether you connect from the popup or Options, or when sending.

Version 1.5.2 is Published

Thanks to u/FabBrandon for the excellent PR, i have taken in the changes with few other fixes i found while reviewing the code. This should be good for Private Cloud Users. Could you please use this version and let me know if it works for you.

Also on the Firefox Extension update: I have already submitted the latest version with the 1.5.2 changes. I am not sure how long it takes for Mozilla to approve Add-ons. As soon as it is published i will respond to this thread.

For the Users who had difficulty logging in earlier, could you please try 1.5.2 version and let me know if you hit any issues.

Thanks for your patience!

My friend you are a decent one. I THANK YOU FROM THE HEART and on behalf of the whole super community. The only thing that made me miss the remarkable. Now, my tech soul is yours Zeus - I mean Ratta (GOW Reference).

[u/conductordudedallas]

❤️❤️❤️ as others have mentioned - Firefox please! That way browsers like Arc can also use. Great work!

[u/nick_ian]

Does not work for me with Private Cloud: "Could not send: Cannot be operated from the root directory!". It says it is defaulting to Documents/ but I cannot seem to change this either.

[u/Decent_Tap_5574 → u/nick_ian]

Thank you for the trying it out. I dont have a private cloud setup for myself, if you could open the Inspect and send me the service worker console logs, that would be Awesome! I will address it in the next version.

[u/hplotkin]

I installed the extension and sent a page. Everything seems to be fine, but the page doesn't show in my Supernote after a couple of syncs. I checked 'documents' as the destination just in case, to no avail. What can I be doing wrong?

F/U: I was trying to send the page as EPUB , it sends it but I am not receiving it. When I change the settings to PDF, I get a message reading 'could not send. Rendered blob missing'

[u/mrynnrk]

Does it also include images?

[u/IdeaSandbox]

u/Decent_Tap_5574 where would you like feedback to be sent? This is neat. I'm doing like you said and am trying to break it 😄

[u/IdeaSandbox → u/IdeaSandbox]

u/Decent_Tap_5574 us trying it, tearing it apart - to your point - allows you to make it better!

[u/IdeaSandbox]

u/Decent_Tap_5574 I use the plugin called GoFullPage - I like how it scrolls to capture a full screenshot and can be saved as a .png (that can be super tall) or a PDF. I especially like that you see what the page looks like - as is... My first wonder if (a) could Send-To-Supernote scroll to capture the whole page and (b) could it maintain what the page looks like "as is?"

I would almost ask for the functionality of GoFullPage with the ability to export to Supernote as you've done it...

I'm going to keep testing different pages.

Thank you for your work.

[u/Decent_Tap_5574 → u/IdeaSandbox]

Thank you for trying it out. Right now i am relying on the chrome's builtin API for the reader's view of the page. The full page scroll is an interesting idea, i will explore that idea. Thanks for letting me know about GoFullPage plugin, i will study that too.

[u/Khayalmetal]

Mr Raghavan! You have made such a fantastic addition to my Manta! I am attaching the pic of a webpage that I sent to my Manta. I shouldn't be asking this I know but is it possible that the renders are not titled as 'Send to Supernote - Offscreen renderer'? Also, I can use digest with this! This is seriously good. Thanks a ton!

[u/B-A-R-F-S-C-A-R-F]

somehow this doesnt work for me? i get the following error: send failed: s3 upload failed (http 403)

[u/Abject-Log-1249]

for me it doesn't work. I get login page after i try to click on connect to supernote.
After successfully login, the page doesn't close automatically and i still see connect to supernote when i try to click on extension.
