Write what's on your mind — something you feel, notice, or just did. It becomes a star. Astruno finds people across the world experiencing the same thing. Their stars drift toward yours, forming constellations of shared experience. Discover thoughts on a 3D globe by location or a living sky by meaning. Tap any star to read what someone across the world is going through. Pseudonymous. Text-first. Discovery by resonance, not virality. No clout, no noise. Just "who else right now?"

Hey Product Hunt! Solo indie dev here — built Astruno from scratch.
It started with a question I couldn't shake: "Who else, right now?" Not just feelings — I'd be doing something mundane like eating cereal at 1am and wonder if someone on the other side of the world was doing the exact same thing.
So I built it. You write what's on your mind — something you feel, notice, or just did — and it becomes a star. AI finds people across the world experiencing the same thing, and their stars drift toward yours, forming constellations.
There are two ways to explore. A 3D globe shows you where thoughts come from geographically. A living sky clusters them by meaning — so two people describing the same feeling in completely different words still end up next to each other.
It's pseudonymous and text-first. Pick a nickname, write in 250 characters or less. There are replies, DMs, and a feed if you want them — but the heart of it is spatial discovery. You find people through resonance, not through who has the most followers.
I'd love for you to try it. Post a thought, then look at the sky — someone out there is probably going through the same thing.

Quick update since launch —
The sky view now groups thoughts by meaning. So when you zoom out, you see constellations form around shared themes — not because I labeled them, but because similar thoughts naturally drifted together. Two people writing about missing someone in completely different ways end up as neighboring stars.
The globe has shooting stars when you zoom out. Zoom in and you see individual thoughts pinned to real locations. There's something unexpectedly moving about seeing a dot light up in a city you've never been to and reading a thought you've had word for word.
One thing I didn't expect: people don't just post deep feelings. Someone posted "eating ramen alone at my desk" and three other people across different time zones had posted almost the same thing within the hour. That's the part I love — it's not just the heavy stuff. It's the mundane moments too.
If you've tried it, I'd genuinely love to hear what your experience was like. And if you haven't — post one thought. Just one. See what comes back.
Same impact, no jargon. The "how" matters less than the "what it feels like."
