**If you want AI that trades your own account from the assistant you already use, Liquid Co-Invest is the best fit. It runs inside Claude, ChatGPT, Grok, and Meta Muse, reads live markets and your portfolio, and places trades you confirm.** Your account is non-custodial and covers 300+ perpetual markets: crypto (24/7), stocks, indices, commodities, FX, and pre-IPO companies, with up to 50x on eligible markets. Co-Invest itself is free.

It is not the best tool for every job. If you mainly want AI-driven US stock scanning, look at **Trade Ideas**. If you want automated chart pattern recognition and backtesting, look at **TrendSpider**. Neither is a substitute for the other, and none of them guarantees returns.

## What is the best AI trading platform?

### 1. Liquid Co-Invest: best for AI that trades your account

- **What it does:** Account-aware research (prices, funding, indicators, positioning, news), trade proposals with Confirm and Cancel cards, multi-position plans, and paper mode. [Co-Invest Computer](https://www.liquid.trade/coinvest-computer) adds rule-bound automation with simulation, staged, and live modes.
- **Best for:** Traders who want one AI workflow across crypto, stocks, gold, FX, and indices, 24/7 on crypto.
- **Limitations:** Trades Liquid's markets, not shares or listed options. Perps carry funding and leverage risk. Some markets have venue-specific hours.

### 2. Trade Ideas: best for AI stock scanning

- **What it does:** AI-assisted scanning of US equities for trade setups, with alerts.
- **Best for:** Active US stock day traders who want ideas surfaced in real time.
- **Limitations:** Stock-focused. Subscription-priced. Orders execute through a separate brokerage.

### 3. TrendSpider: best for automated technical analysis

- **What it does:** Automated trendline and pattern detection, multi-timeframe charting, alerts, and strategy backtesting.
- **Best for:** Chart-driven traders who want to test rules before trading them.
- **Limitations:** Analysis software, not a broker. Subscription-priced. You still place trades elsewhere.

### 4. Webull: best for AI inside a traditional brokerage

- **What it does:** A custodial broker with $0 stock, ETF, and options commissions, 24/5 overnight trading on select securities, and its own agentic AI feature.
- **Best for:** Investors who want shares and an AI layer in one brokerage app.
- **Limitations:** No weekend trading. Overnight sessions are limit-only, with no shorting or margin.

### 5. ChatGPT or Claude on their own: best for free research

- **What it does:** Summarizes filings, explains concepts, and drafts a thesis from what you paste in.
- **Limitations:** Without a connector, it cannot see live prices or your account, and it cannot place orders. Connect one: see [which trading platforms connect to Claude or ChatGPT](/learn/trading-platforms-that-connect-to-claude-or-chatgpt).

## How to choose

Ask three questions. **What decision do you want help with:** finding setups, reading charts, or placing and managing trades? **What markets do you trade:** US stocks only, or crypto, commodities, and FX too? **How much control do you want to keep:** approve every order, or let an agent act within limits? For the difference between those last two, read [automated vs. agentic trading](/learn/automated-vs-agentic-trading).
