Search Substack with a writer's eye.
Find the posts, publications, and people shaping a topic—then turn the useful ones into a focused research list.
Public Substack results, organized for editorial research
Explore
Start with a topic, name, or phrase
Search posts for evidence and angles, publications for competitors, or writers for possible collaborators.
Filters that matter
Narrow posts by date and language, then sort the page by recency or engagement.
A built-in research desk
Save useful sources on this device and export a clean brief or CSV when you are ready.
A better research loop
Go from curiosity to a useful source list.
The point is not to collect more tabs. It is to see who has covered the topic, what angles repeat, and where your own contribution can be sharper.
Map the field
Search posts for the conversation, publications for competitors, and writers for possible collaborators.
Separate signal
Use date, language, and engagement data to narrow the page without losing the original relevance order.
Carry it forward
Bookmark the strongest sources and export them into the workflow where your draft actually happens.
Useful context, without copying the library.
Every result links back to its original Substack page. Stackflyer does not republish articles, bypass access, or store your research list on a server.
Start a searchWhat does Stackflyer search?+
It searches publicly available Substack posts, writer profiles, and publications. Private drafts, subscriber email addresses, and paywalled article text are not included.
Is this the same as Google search?+
No. Results come from Substack’s public search data and stay focused on the Substack ecosystem. Stackflyer then adds editorial filters, sorting, and a saveable research list.
Why can result counts change?+
Substack search is live. New posts appear, older items change, and relevance ranking can move between searches. The count shown is for the current page, not a promise of the total index size.
Where are saved results stored?+
Your research list is stored only in this browser’s local storage. It is not attached to an account and can disappear if you clear browser data.
Does Stackflyer bypass paid access?+
No. A result can point to a paid post, but Stackflyer only shows public metadata and sends you to the original page. It does not retrieve subscriber-only content.
