Free AI Stock Screener: The 7 Best Tools in 2026 (No Credit Card)

For this guide, "free" means three things: (1) no credit card to start, (2) no automatic conversion to paid after a trial, and (3) genuine AI features — not just a rule-based filter labeled "AI" for marketing.

That second point eliminates most of the screeners you will see in a Google search. Tools like Trade Ideas, Tickeron, and TrendSpider all advertise free trials, but every one of them requires a card and converts after 7–14 days.

The 7 platforms below all pass the test. We have used each one in production and ranked them by what they are actually best at.

1. Quanta AI (Starter, free forever) — The only screener on this list that ranks results by an AI-generated probability score from a verified-track-record signal engine. Free tier includes 5 AI copilot chats/day, 3 Time Machine pattern analyses/day, the full screener (ranked by Quasar signal strength), and the live public proof fund. Best for traders who want actual AI signals on a free plan. [Sign up free →](/signup)

2. Finviz (Free) — Industry-standard rule-based screener with 70+ filters. No AI signals, but the filter depth is unmatched. Best for fundamental screening and the visual market heatmap.

3. TradingView (Free) — Best free charting on the internet, decent screener, social feed of trade ideas. AI features are limited to the indicator marketplace. Best for charting first, screening second.

4. Yahoo Finance Screener (Free) — Solid coverage of US stocks with basic fundamental and technical filters. No AI. Best for quick fundamental scans without signing up.

5. Stock Rover (Free Tier) — Strong fundamental screener with research reports. Free tier has 250-screen limit. No real AI. Best for long-term value investors.

6. Simply Wall St (Free) — Visual "snowflake" analysis of each stock across 5 factors. Limited screening but visually unique. Best for at-a-glance fundamental health.

7. ChatGPT (Free) — Not a screener in the traditional sense, but the free tier can analyze any stock you ask about (with a knowledge cutoff caveat). Best for educational queries; not for live signal generation.

The honest ranking: if you want a free AI-powered screener — meaning the AI actually ranks the output — [Quanta AI](/signup) is currently the only option that delivers. The rest are excellent free tools, but the "AI" in their marketing is mostly marketing.

Genuine AI ranking. A real AI screener should rank its output by a model-generated probability or signal score, not just "stocks where RSI > 70." Most free screeners are still rule-based filters.

A real free tier (not a trial). If you have to enter a credit card, it is not free. Period.

Verified performance. If a screener claims its AI works, it should show you a public track record. If there is no /performance or /track-record page, assume the signals are marketing.

Coverage breadth. The best screeners cover 3,000+ U.S. equities, not just the S&P 500. Crypto coverage is a plus.

Speed and freshness. Free does not have to mean slow or stale. Quanta AI's screener updates in real time on the free tier. Finviz Free has a 15-minute delay.

Use one as your primary, one as a cross-check. No single screener is perfect. We pair Quanta AI's signal-ranked screener with Finviz's fundamental filters and find ~80% of our trade ideas from the overlap.

Save your favorite screens. Most tools let you save filter combinations. Build 3–5 templates: "AI signal + above 200-day SMA," "AI signal + earnings in next 30 days," "AI signal + volume spike."

Verify the signal source. Before acting on any AI-screened idea, check the platform's track record. Quanta AI exposes the [pattern matches](/performance) that generated each signal — you can see exactly why the AI is bullish or bearish.

Combine with a paper account. Run any free screener's picks through paper trading for 30 days before committing real capital. The free tier is more than enough for this.

Free AI stock screeners that actually use AI are still rare in 2026. Most "free" trials hide behind a credit-card wall, and most truly-free screeners are rule-based filters with AI in the marketing.

If you want a genuinely free AI-powered screener with verified signals, a public track record, and no credit card requirement, [start with Quanta AI](/signup). If you want raw filter depth without signals, add Finviz on top. Together they replace the entire "AI screener" category for free.

The Pro plan ($79/mo) unlocks unlimited signals and the full crypto suite when you are ready, but the free tier is enough to start trading immediately.
