Kemono & Pawchive Download Button

A userscript for Kemono, Coomer and Pawchive: download posts, files and whole creators in one click, read posts in a cleaner interface, and translate titles, text, comments and even the text inside images.

Install

Install / update the userscript

The link is permanent: your userscript manager checks it for updates on its own. What changed in each version is in CHANGELOG.md.

Manager	Status
Tampermonkey	Reference host
Violentmonkey	Supported
AdGuard (desktop and Android)	Supported. It has no userscript menu, so open settings with the Downloader Settings and UI Settings buttons in the site's header or sidebar

Greasemonkey 4 is not supported: it only offers the GM.* API.

Supported sites

Service	Domains
Kemono	kemono.su, kemono.cr and their subdomains
Coomer	coomer.su, coomer.party and their subdomains
Pawchive	pawchive.pw, pawchive.st and their subdomains

Features

Downloading

• Post buttons: the whole post as a ZIP, images only, attachments only, links copied in aria2/IDM format, links saved as a text file, or shared.
• Streaming ZIPs built with fflate, so large archives do not freeze the page. Compression level is configurable; the archive can include metadata.json, the post text, tags, comments and an HTML index.
• Pick files before downloading, and skip extensions you never want.
• Bulk downloads from a creator's page: tick posts (or Ctrl+click and Shift+click cards) and get one archive or one per post. The author manager downloads every post a creator has.
• Reliable fetching: configurable retries, cancel any task, automatic fallback to the file host, and an IndexedDB cache of files and post metadata.
• File name templates with {author_name}, {post_date}, {post_title}, {post_id}, {user_id}, {service}, {file_index}, {global_file_index}, {file_name}, {original_file_name}, {file_ext}.

Reading

• Image gallery with thumbnails and a lightbox (zoom, pan, swipe, download the original, search with Google Lens).
• Video player built on Plyr, replacing the site's own player.
• Link buttons for Mega, Gofile and other hosts, with passwords recognised even when glued to the link.
• Comments as a list, a grid of equal cards or a carousel; author replies threaded under the comment they answer; long comments expand in place.
• Empty sections hidden, viewed posts marked, adjustable card grid, and an optional built-in ad blocker.

Translation

• Text: the post title, its content and every comment get their own translate button. Google and Yandex work without a key; OpenAI-compatible APIs (OpenAI, Gemini, OpenRouter, local servers), native Gemini and DeepL need one.
• Text inside images through Google Lens, rendered in place the way Chrome's Lens overlay does it: manga mode, two ways of erasing the original, line spacing, re-wrapping, and answers remembered across reloads. No key needed.

Development

Requires Node.js 22 or newer.

git clone https://github.com/bropines/kemono-download-button.git
cd kemono-download-button
npm ci
npm run typecheck
npm run build

npm run build bundles src/ with Vite and writes the single file kemono-download-button.user.js, with the metadata header taken from src/index.ts.

src/
  api/          site REST clients (Kemono/Coomer, Pawchive)
  config/       constants, selectors, icons, default settings
  features/     reading UI: gallery, video, comments, translation buttons, ad blocker
  services/     downloads, ZIP, cache, queue, translators, Lens image translation

Releasing

Every push to main reaches users through the auto-update link, so the committed script must always be a build of the committed sources. CI checks that, and that the versions agree.

1. Bump the patch version in package.json and the @version line in src/index.ts.
2. Note user-facing changes in CHANGELOG.md under ## [Unreleased].
3. npm run build and commit the rebuilt kemono-download-button.user.js together with the sources.
4. Push to main. For a GitHub Release, rename [Unreleased] to the version and date, commit, then push a tag: git tag v0.8.50 && git push origin v0.8.50. The release notes are that section of CHANGELOG.md, and the release fails if it is missing.
