Show HN: Podly – From podcast listening to podcast learning (Obsidian for audio)

I built Podly because I was listening to tons of podcasts and realizing I wasn’t retaining any of it.

Podly is a podcast companion that helps you turn passive listening into active learning. It builds you a personal memory graph from the episodes you’ve heard. You can search for ideas, trace connections across shows, and explore your podcast history like a second brain.

Think of it as Obsidian for audio - searchable, connected, and personalized.

Most of it is already built (you can see this in the demo), but I’m still refining the experience. I launched a landing page and waitlist to gauge interest and learn from early users before opening it up fully.

I’d love to hear your thoughts. Do you treat podcasts as learning tools, or just background noise? What would make something like this genuinely useful in your workflow?
