Inkling: Send/receive anything between your Supernote and other devices — with or without LocalSend
Inkling is an open-source Supernote plugin that lets you insert text, images, links, PDFs, clipboard content, and more into your Supernote from a PC or any other device. It is able to run completely offline as it communicates only through your local network. This project has no commercial plans.
It integrates with LocalSend, a free, open-source cross-platform file sharing app, but offers more than just that.
Beyond LocalSend, Inkling also supports:
- Lasso Send: Select text, images, screenshots, or links on your Supernote and send them to other devices via LocalSend
- Doc-Screenshots-to-Note: Very useful for Long Screenshot or multiple screenshots.
- Layer Management: Supports using the pen as a temporary lasso to select elements without switching tools. Adjust layer order for the current layer or lasso-selected elements.
What you can receive via LocalSend:
- Doc Links: Inserted as tappable links
- Images: Including doc screenshots
- Text: With paragraph mode (preserves line breaks) and no-space mode (strips whitespace, useful for CJK text)
- Clipboard: Basically what you've been selecting: writing, painting and textbox, it's 2026 and there's still no official clipboard on any e-ink device.
About LocalSend: LocalSend is a free, open-source app for securely sharing files between nearby devices without needing the internet. It's available on Windows, macOS, Linux, Android, and iOS.
I've been developing this for a while since it's been incredibly useful for my own workflow, but I wasn't planning to share it until it was more polished. Now I realize it's ready enough for a public release — and I'd love to invite developers to collaborate.
One area where I'd especially appreciate help: image display filter algorithms. Dithering is the current go-to, but it doesn't always look great on e-ink. If you have ideas for better pre-rendering or quantization approaches, I'm all ears.
Future plans:
- Local re-typesetting engine for epub, mobi, azw3, md, txt, and pdf with better e-ink rendering quality on Supernote.
- Integration with CherryStudio / RikkaHub / ChatWise / SillyTavern directly on your Supernote.
I've tested this for a while but couldn't iron out every bug — if you'd like to contribute, PRs are very welcome! :D → Repo: Inkling
