Hi hunters! 👋 I’ve always loved Substack, but I found myself getting frustrated whenever I wanted to find an old post from a writer I’ve followed for years. Substack’s default archive can be a bit of a maze once a publication gets large enough. I built Substack Archive Explorer to turn that 'maze' into a library. My goal was to make it effortless to search, filter, and surface the 'evergreen' content that often gets buried under the newest posts. I’d love to hear what features you think are missing, I'm planning to keep refining this based on how you all use it!
