Substack Exporter
Back up entire Substack publications as Markdown, HTML or EPUB — including the paid posts you subscribe to. Bundle images for fully offline reading, and export comment threads, Notes, and your subscription list.
Everything Worth Keeping, Kept
Back up the newsletters you read — and paid for — in formats built to last
Full Archive Backup
Walk the entire archive of any publication and save every post — one Markdown file per post with frontmatter, plus a metadata index.
Your Paid Content Included
Posts behind the paywall export in full for publications you subscribe to, using your own browser login. Back up what you paid for.
Markdown, HTML & EPUB
Choose clean Markdown for your notes app, self-contained HTML for browsing, or EPUB for reading whole publications on your e-reader.
Fully Offline Media
Optionally download every image in every post. Links are rewritten to local files so archives stay readable even if Substack goes away.
Comments, Notes & Reads
Export full comment trees with reply structure, any user’s public Notes, their Reads list, and your own subscriptions as CSV.
Reliable Task Engine
Exports run in the background with automatic resume after rate limits, network errors, or browser restarts. Progress is never lost.
Perfect For
Whether you read on an e-reader, archive for the long term, or study the conversation
Offline Reading
Turn a whole publication into a single EPUB and read years of writing on your Kindle or Kobo, no internet required.
Permanent Backup
Writers delete posts, publications move, subscriptions lapse. Keep a local Markdown archive of the content you paid for.
Research
Export comment threads with full reply structure, Notes activity, and Reads lists as CSV for content analysis.
