Show HN: Spot Canvas – AI-Powered trading charts for learning and automating TA
spotcanvas.comHi HN,
About a year ago I started tinkering with drawing candlestick charts on an HTML canvas. What began as a small experiment turned into a full-blown crypto charting library.
At some point I asked myself: could this actually become a competitor to TradingView? That felt overwhelming, since TradingView has an enormous feature set. Still, I kept building — partly because I enjoy side projects more than watching TV
By the summer, I had a working SaaS version. But it felt like it was missing something that would make it truly stand out. Then I realized: the chart itself should be AI-powered.
Unlike tools where you screenshot a chart and feed it into ChatGPT (there are some like this), I already had my own charting library, so I could integrate AI deeply into the workflow. Over the past two months, I built an assistant I call Spotlight AI. It can:
- Analyze the chart and explain what’s happening - Spot patterns and highlight indicators - Respond to commands like “switch to ETH/USDT 1h” or “draw a trendline” - Help you navigate and learn TA concepts in real time (live prices on the chart)
I’d love feedback — both on the idea of AI-assisted charting, and on the product itself. (You’ll need to sign up to try Spotlight AI).
