Questions, answered
Simple by design.
The downloader works with public Substack article pages and respects the access set by each writer.
Can I download paid Substack posts?+
Stackflyer only downloads the content that is already publicly visible. For a paid post, that normally means the free preview—not subscriber-only text.
Does it work with custom Substack domains?+
Yes. Paste the full post URL, including custom-domain links that contain /p/. Stackflyer verifies that the page is powered by Substack before processing it.
What is included in the download?+
The article title, subtitle, byline, source link, and cleaned post body are included. Images and useful links are preserved when they are publicly available.
Do you store the article?+
No. The post is fetched and converted for your request. The downloader response is not cached, and you do not need an account.
