Blog to Newsletter
— Blog to Newsletter generates Substack-ready newsletter HTML from the Datasette backup of simonwillison.net, pulling entries, links, quotations, notes, guide chapters, and beats from a 1 to 60 day window. Users can skip content from prior newsletters (using the Substack RSS feed or pasted RSS XML), limit posts to content before a cutoff comment, reorder entries with drag-and-drop or arrow keys, and add a sponsor message with monthly preview links.
