Tips
Works best with articles, blog posts, documentation, and wiki pages
Images are resized to 1200×1600 max and converted to grayscale for e-ink
Use "Combine all" to merge multiple URLs into a single EPUB with chapters
Paste raw text or markdown for offline content — no URL needed
The SUMI Post (newspaper builder) is better for RSS feeds and daily news
Privacy note: URLs are fetched through public CORS proxies
(allorigins.win / corsproxy.io / codetabs.com) because browsers block direct
cross-origin requests. The proxy sees the URL and the page response. Don't
clip URLs that contain private session tokens or authenticated content.
