Use case
Convert a Substack post to Markdown
Turn a Substack newsletter into clean Markdown for your notes or for summarising with an AI assistant.
Substack posts convert cleanly. The platform serves its articles as plain server-rendered HTML with a simple structure, so extraction is close to lossless — footnotes, block quotes and section breaks all survive.
The exception, as everywhere, is subscriber-only content. If a post is gated, the fetch returns the preview and the subscribe prompt.
Usually works
Public Substack posts convert reliably. Subscriber-only posts return a paywall message.
Step by step
- Copy the post URL from the newsletter or your browser.
- Paste it into the converter and press Convert.
- Copy the Markdown, or download it as .md to keep in your notes.
Worth knowing
- Long-form newsletters are a good fit for AI summarising — convert, paste, and ask for the argument in five bullets.
- Substack's comment section is not part of the article and is not included.
- Footnotes are preserved as Markdown links back to their definitions.
Questions
- Does it include the subscribe box and footer?
- No. Calls to subscribe, share buttons and the archive footer are treated as page furniture and removed.
- What about posts on a custom domain?
- They convert identically — a Substack on its own domain is still Substack underneath.
