tradingviewai.dev — AI Pine Script generator: time-saver or shortcut trap?

Stumbled on https://tradingviewai.dev/?wlj — it turns plain-language trading ideas directly into ready-to-paste Pine Script for TradingView. Say "buy on 50/200 SMA cross" and you get complete code with explanations, no coding background needed.

I've been using it to rough out new indicators faster than typing from scratch — but I'm watching where it cuts corners. The generated code looks clean for simple setups, but I haven't pushed it past basic strategies yet. Debugging or adding custom logic still needs human oversight.

Who's put this through real backtesting? What's the limit — does it fall apart on multi-timeframe logic or more complex systems? And has anyone compared it to TradingView's own AI Copilot or other generators?
