Built an AI crypto assistant that watches the market so I don’t have to doomscroll CT all day

Spent the last few months building this as a solo side project and finally shipped it, figured I'd share.

It's called JCA (Josh's Crypto Aid). You build a watchlist, it pulls live prices and news, and an AI (Claude) actually analyzes both together and gives you entry/exit zones with a reason behind it, instead of just dumping charts on you and making you figure it out. There's also a daily picks feature that scans trending coins and surfaces a few that actually stand out, with reasoning attached.

No trading execution, it doesn't touch your wallet or move money, it's purely research/decision support. Built with Next.js, Supabase, and the Claude API.

Still actively working on it, would genuinely love feedback, especially if something breaks or feels confusing. Also happy to answer questions about how any of it was built if anyone's working on something similar.
