I've noticed that quite a few people are asking for AI-powered tools for trading, especially free solutions. Here's what I use or have tested.

First, TradingView remains a must-have. It's not 100% AI, but smart indicators and Pine Script scripts really allow you to automate your strategies. The cool thing is that you can backtest before risking real money. The free version already offers a lot, and the pro version is for those who want more advanced tools.

Next, there's TrendSpider, which works differently. The AI automatically detects price patterns, trend lines, Fibonacci levels... It's fully automated technical analysis, with alerts when a signal appears. Basic free version, but if you want to truly harness AI power, you'll need to upgrade to paid.

For those interested in on-chain data and market psychology, Tuner AI is pretty good. The AI analyzes data and suggests entry points based on what it detects. Free initially, with a premium version if you want more.

Now, for automated trading, two names keep coming up: CryptoHopper and 3Commas. Both use artificial intelligence to optimize strategies. CryptoHopper supports several major exchanges, with a free plan but limited features. 3Commas is similar, offering DCA and Grid Trading with risk management via AI. Also limited in the free version.

The real question is: what exactly are you looking for? Pure automation, assisted technical analysis, or just signals to help you decide? Because free AI trading tools do exist, but each tool has its specialty.
