I have compiled a list of free AI trading tools that are really worth it if you're just starting out or looking to optimize your strategies without spending a fortune.

First, TradingView is essential. It’s not 100% AI, but the smart indicators and the ability to create custom scripts in Pine Script to automate your strategies are powerful. You can backtest your strategies before launching them. The free version already offers a lot, and if you want more advanced tools, there is the pro version.

If you're looking for more automated technical analysis, TrendSpider does the job. AI automatically identifies price patterns, trend lines, Fibonacci levels... Signal alerts notify you when something interesting happens. The limited free version is enough to get started.

For those who really want free AI trading with an on-chain approach, Tuner AI offers blockchain data analysis and market psychology insights. You receive entry points based on AI data. Free access to the base, with a premium option if you want more.

Now, if full automation interests you, CryptoHopper is a bot that uses AI to optimize your strategies. It connects to most major exchanges. A free plan is available but with limits on the number of transactions.

And there’s 3Commas, another AI bot for DCA and Grid Trading. The AI manages risks and aims to optimize your profits. Free version available as well, but the number of bots is limited.

The real question is: what exactly are you looking for? Pure automated trading, better technical analysis, or just signals to help you decide? Each tool serves a different need, so it really depends on your approach.
