Substack Exporter saves Substack newsletters to your computer for offline reading and backup. What it exports

All posts of a publication, or a single post, as Markdown, HTML or EPUB
Comment threads of a post as CSV, with reply structure preserved
Notes and Reads of any user profile
Your own subscription list

About paid content: posts behind a paywall export in full only for publications your account already subscribes to. The extension uses your existing browser login and cannot bypass paywalls. Details

Works on substack.com subdomains and custom domains
Can download all images in posts, so archives stay readable fully offline. Links in the exported files point to the local copies
EPUB export packs a whole publication into one file for Kindle or Kobo
Exports run in the background and resume where they stopped after rate limits, network errors or browser restarts
Everything is processed locally in your browser. No data is sent to any server
