Nothing to crop or stitch
The layout is already set: author on top, text centered, images in proportion, metadata at the bottom. No aligning, no padding, no font sizes to guess.
Use case · Share images
Tweets, Xiaohongshu notes and Instagram posts, turned into share images in one click
You see something worth passing on, and a screenshot means cropping it yourself while the page's buttons and recommendation rails come along. Shunshou lays the page out as a clean card instead — author, text, images and date each in their place, with a QR code in the corner that leads back to the source. One click to render, copy and post.

Why not just screenshot
A screenshot captures the screen; a share image gives you the content
Screenshots are fast, but what you post is a piece of someone's page: the nav bar, the like button and the rail next to it are all in there, and you still have to crop. After cropping, the sizes don't match, so each platform squashes it again.
A share image re-lays out the content: who wrote it, what they said, what pictures came with it, when it was posted — at a fixed size with even margins, so what you post is a finished piece.
The three above aren't three features — they're one share-image capability reading each site's own fields. So a new site needs no waiting for support: give it a few fields and it renders.
Images completed for you
Carousel images on Xiaohongshu notes and Instagram posts are completed automatically (no opening each one) and laid out as a photo wall; tweets bring author, date, text and images.
Long text, not cut off
With pagination on, text past one card's limit is split into several images, continuation pages carrying the title and page number — a long article still goes out whole.
A way back to the source
A QR code in the corner opens the original page; it can also point at a download link for the app itself. The code is generated locally — no network, nothing uploaded.
Zero setup, no connection needed
Unlike saving to a note app, share images work as soon as you install: no account, no API, no network dependency.
Look before you keep
The image stays in the result dialog for preview; copy or download when you're happy. It never dumps files onto your disk, and never posts anything for you.
What comes out
Three platforms, three cards
All of these are real output, unedited. The same action reads each site's own fields, so the layout stays consistent while the content follows the site.
The render is the workbench
Change it in place, then save it back into the action
The dialog after rendering is the preview: open the full-size image if it's hard to read, and expand "Adjust" to change how it looks. Changes apply to this run; when you're happy, "Save to action" makes them the default.
Four themes
Paper / Ink / Brand / Plain white — from warm paper to pure white, with light and dark palettes that follow your system.
Four sizes
Tall (auto height) / 4:5 / 3:4 / 1:1 — for a timeline, a note, or a cover; the tall size fits as much of the text as it can.
Font and background
Fonts come only from what's installed on your machine (nothing is downloaded), and any CSS font-family works too. With a custom background, text and QR code are given automatic contrast.
Add, remove, reorder blocks
A card is a list of blocks, each a template that can reference any variable: drop the date, or drag the rating to the top.
Edit the text for this run
"Share full text" lets you edit this run's body in place — affecting only this run, not your config; save it back to the action once you're happy.
Watermark and signature
No text by default; fill in the watermark to sign your work. The QR code has three settings: current page / brand homepage / off.
Works with annotations
Selections and highlights can be rendered too
It doesn't have to be the whole page. See a sentence worth posting, select it — "Share quote" on the capsule renders a card of just that passage. Or mark things as you read and deal with them at the end.
Selection → quote card
Select a passage and click "Share quote": the card is that passage plus its source, which is exactly what you want for a line from an article or a book.
Web highlights
Select text and click Highlight; the mark stays on the page, surviving a reload and without changing the site's own structure.
Click it again to copy or remove it (a removal can be undone); all highlights on the page can be copied as text or saved to your notes in one go.
Have AI summarize first
The "AI summary card" action has your own model boil the passage or page down to key points, then lays it out on the same card — same design, different content.
Post it, or file it
After rendering you can carry on: copy the image into a chat, save the file, or add a "Post to X" step that opens the official share box prefilled — you always confirm before anything is published.
More than social
It isn't only for social platforms
Share images are a general capability: any page whose fields you can read can be rendered.
Whole-article tall image
"Share full text" lays the page's text and images out in reading order, splitting into several images when long instead of cutting — far cleaner than a scrolling capture, and no floating ads get caught in it.
Book, film and game cards
Douban book, movie and game pages yield 17 / 20 / 11 fields, so a book card or a film card can carry rating, cover and director — nicer than a screenshot.
GitHub repository card
Copy owner/repo, or render the repository's details as a card — handy for recommending a project in a group chat.
Bilibili video card
Video details and comments (nested replies included) can all be read; a share card works better in a group chat than a bare link.
Save as a local file
The rendered image can be saved straight to disk, with a configurable filename template such as Shunshou/{{date:YYYY-MM-DD}}/{{title}}; same-name files are numbered rather than overwritten.
Post to several platforms
X / Weibo / Bluesky / Telegram / Mastodon / Reddit — each opens its official share box prefilled, and you confirm in the editor before it goes out.
FAQ
Questions about share images
How is this different from a screenshot?
A screenshot captures the screen, including navigation, buttons and recommendation rails, and you still have to crop it. A share image keeps only the content — author, text, images, date — re-laid out as a card at a fixed size with even margins, so it doesn't get squashed again when you post it.
It's also not a bitmap of a screen: change the theme or size and it re-renders, instead of needing another screenshot.
Does it get every image from a Xiaohongshu note or an Instagram post?
Yes. Carousel images are completed automatically (no opening each one) and laid out as a photo wall; tweets bring their author, date, text and images.
Images come from what the page has already loaded, so it never bypasses a login or reaches for private content.
What about very long articles — do they get cut off?
No. With pagination turned on, text beyond one card is split into several images, with continuation pages carrying the title and page number.
With pagination off, the tall (auto-height) card already fits a very long article (on the order of 7,000 characters); only past that is it truncated with an ellipsis.
Can I use the image right away?
Yes. The finished image stays in the result dialog where one click copies it, ready to paste into a chat or a document; you can also download the file or save it locally.
Turn the QR code off if you don't want it, or point it at a download link for the app. And "copy" means copy — it won't quietly leave files on your disk.
Is there anything to configure?
No. Share images need zero configuration and depend on no account, connection or API: install and it works, with no network needed either — the QR code is generated locally and the images are the ones the page already loaded.
Can I add a watermark or my own signature?
Yes. Watermark text, background color and font are all editable; four themes (paper / ink / brand / plain white) and four sizes (tall / 4:5 / 3:4 / 1:1) can be picked per piece, and your choice can be saved back into the action as the default.
Does it cost anything? Do I need an account?
It's free, with no ads and no features locked behind payment, and there's no account to create. Config stays in your browser.
