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. https://trypodly.com https://trypodly.com 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?
