About this extension
KindleFlow turns readable web articles into Kindle-friendly EPUB files. The browser extension is the
recommended way to save paid Substack posts because it works from the page you can already read in
your browser.
Open a readable article, click the KindleFlow extension, and send the current page to your configured
KindleFlow server. KindleFlow imports the rendered article, generates an EPUB, and can automatically
send it to your Kindle email address when your KindleFlow profile is configured for auto-send.
The extension does not read, store, or transmit Substack cookies.
