EchoMood
Built EchoMood during Bolt’s World's Largest Hackathon—first time messing with this type of vibe code tools to ship something fast. Originally, I tried to go all-in and build a mobile-native app, but I hit a weird error that only showed up on a real phone. Spent three days poking at it, switched to another vibe code IDE, still couldn’t squash the bug.
So, I just pivoted: I turned it into a PWA and set up Stripe for payments instead.

Here’s the idea: EchoMood lets you type out how you feel, then picks a persona to reply to you in actual voice (using ElevenLabs API). Every response uses up a credit—you can buy credit bundles if you want more replies.
Honestly, the point is to get your thoughts echoed back, in the vibe you need. If you’re down and need a cheerleader, or just want some calm reassurance, EchoMood figures out your mood from your text and gets the right voice persona to reply. It’s like having your own little support squad, on demand.
What’s next? Still want to solve that native app bug and push it live for real. I'm curious to see how folks will use it in the wild. We’ll see how it goes.
