Synaptive
Map the books, films & podcasts that shaped your thinking
What it does
Synaptive lets you build visual knowledge graphs from the content you consume. Add books, movies, podcasts, articles — search real APIs or add manually.

Share your graph publicly and discover how others connected the same content differently.

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
