AI Stock Screener Comparison 2026
7 Tools Tested Side-by-Side
I paid for and tested all 7 AI stock screeners on this page — including Trade Ideas Holly AI ($99-228/mo), TrendSpider, Danelfin, and four others. What follows is the real pricing, G2/Capterra ratings, and specific limitations I ran into personally. The filter widget below narrows the list by your actual budget and feature requirements.

Author note: my primary screener setup is TrendSpider ($79/mo Plus) alongside Finviz Elite. I tested Trade Ideas for three months — Holly AI's morning watchlists added little value for my swing-trading style, though I understand why intraday momentum traders like it. Danelfin's explainable AI score is, in my view, the most honest product design in this category.

TL;DR — Key Takeaways
- 1.Trade Ideas Holly AI is the most seriously designed AI signal engine for intraday momentum traders, but delivers little value for swing traders or fundamental investors — and it is not cheap ($99-228/mo).
- 2.TrendSpider ($39/mo) wins for automated technical analysis. Finviz Elite ($24.96/mo annual) wins for the widest fundamental-plus-technical filter set.
- 3.Danelfin ($29/mo) is the only tool among the 7 that seriously attempts AI explainability, and its free tier covers 900+ US stocks.
- 4.Tickeron's confidence percentages ("78% chance of going up") read convincingly but real-world win-rate data from retail users hovers close to random — do not be persuaded by the numbers.
- 5.None of these 7 tools natively include genuine unusual options flow data — this remains a notable gap across the entire category in 2026.

Expand: honest downsides for each tool (hands-on)+
Trade Ideas (Holly AI)
Premium at $228/mo is expensive for a retail trader. Holly AI's morning picks are US-equities-only and skew toward intraday/momentum — if you swing-trade small-caps over days or weeks, the signal degrades fast. The backtesting engine (Brokerage+ OddsMaker) requires a learning curve most users skip. No crypto, no options flow data.
TrendSpider
The automated trendline engine sometimes draws lines that experienced chartists would reject — it favors mechanical regularity over contextual support/resistance. No fundamental data at the $39 tier; stocks-only at lower tiers (crypto costs extra). 7-day trial is short for a tool this complex.
Finviz Elite
No AI whatsoever despite the 2026 landscape. Backtesting is completely absent — if you want to test a screen historically you need to export and build the test yourself. Free tier's 15-minute delay makes real-time screening impractical. Options data exists only as a premium add-on ($9.99/mo extra).
Scanz
No backtesting, no historical scan replay. At $149/mo Pro it is expensive for what amounts to a real-time level-2 scanner without any AI-generated signals. Mainly built for day traders who scalp momentum; swing traders and fundamental investors will find almost nothing useful. No international stocks.
Stock Rover
Data is delayed (EOD) even on paid tiers — if real-time matters, look elsewhere. No options data, no AI signals, no backtesting engine. The 450-metric depth is genuinely powerful for fundamental investors but overwhelming for beginners. International coverage exists but lags US by 1-2 days on corporate actions.
Tickeron
The confidence percentages ("78% chance of going up") read convincingly but the underlying pattern recognition has a mediocre real-world accuracy track record — multiple retail reviewers report sub-55% win rates when followed mechanically. AI Robots are paper-trading examples, not live-executed strategies. G2 reviews flag frequent UI sluggishness.
Danelfin
European company, headquartered in Barcelona — US coverage is comprehensive but non-US coverage is patchy. No real-time data, no scanner alerts, no backtesting. The AI score is daily-updated and not suitable for intraday decisions. Free tier covers roughly 900 stocks — the full 6,500+ requires paid. G2 reviews are sparse (only 15), which limits the rating's reliability.
How I Tested
From the second half of 2025 through June 2026 I used these 7 tools as a paying customer (or through full-length 7-day/30-day trials). The methodology was:
- ·Ran the same screen conditions (RSI <35 + volume 2× average + market cap $500M-$5B) on every tool and compared result sets and execution speed.
- ·Tracked Trade Ideas Holly AI morning watchlist signals for 12 weeks, recording actual next-day (T+1) and T+5 returns for each signal.
- ·Measured real-time scanner alert latency (from trigger to notification receipt) manually with a stopwatch across each platform.
- ·Submitted 2 real support tickets to each vendor and logged first-response time and answer quality.
- ·G2/Capterra scores and Tickeron/Danelfin AI accuracy data are public data as of 2026-06-01 — they drift over time, so verify yourself.

Which One to Pick — 2-Minute Decision Tree
Intraday momentum trader who wants an AI pre-market watch list →
Trade Ideas (Holly AI). Start at $99/mo Standard; the AI feature gap vs Premium is smaller than the price gap suggests.
Chart-heavy technical trader who wants automated pattern detection →
TrendSpider ($39/mo). Automated trendlines + multi-timeframe sync + strategy backtesting is its differentiated advantage.
Fundamental-plus-technical screener, no need for AI signals →
Finviz Elite ($24.96/mo). 65+ filter conditions is the widest at this price point, with usable real-time scan.
Swing trader who wants an explainable AI conviction score →
Danelfin ($29/mo). AI score 0-10 with a factor breakdown panel — currently the most transparent AI stock scoring design available.
Serious fundamental analyst who needs 450+ custom metrics →
Stock Rover ($27.99/mo). Deepest data set, but zero real-time data — do not use it where live prices matter.

Frequently Asked Questions
Does Trade Ideas Holly AI actually work?+
Holly AI is one of the more seriously designed AI signal engines in the retail space. It runs millions of simulated overnight trading scenarios, ranks setups by probability of profit, and delivers a ranked watch list before the open each day. Trade Ideas' own backtests show certain strategies outperforming the market over 2019-2024, but "backtests well" does not reliably translate to "performs live." Real-world user results vary considerably — a G2 score of 4.2/5 means a meaningful share of users are not satisfied. The core limitation: Holly's signals skew hard toward US intraday / momentum trades; for swing traders and fundamental investors there is almost nothing actionable. At $99-228/mo it is not cheap, and you should honestly assess whether your trading style fits the signal type before subscribing.
TrendSpider vs Finviz Elite — which is better?+
It depends on your primary workflow. TrendSpider ($39-129/mo) wins on automated technical analysis — automated trendlines, multi-timeframe sync, strategy backtesting. If your work is chart-heavy, TrendSpider saves real manual drawing time. Finviz Elite ($24.96/mo annual) wins on the widest fundamental-plus-technical filter set (65+ conditions) with real-time scan. If your workflow is "filter down to a short list first, then chart them manually," Finviz is the more efficient first pass. Neither has AI-generated stock picks. Many traders use both together ($65/mo combined), which is a reasonable choice if charting and fundamental filtering are both core to your process.
Are there any free AI stock screeners worth using?+
Among these 7 tools, Danelfin's free tier is the highest-quality option — it provides genuinely AI-driven scores (0-10) for roughly 900 US stocks, with an explainability panel showing which sub-factors drive the score, which is unusually transparent for a free product. Finviz free has broad coverage but no AI — only rule-based filters. Tickeron's free AI signals are extremely limited and are essentially a demo. If your budget is genuinely zero, Danelfin free plus manual chart verification is the most practical combination. Note that Danelfin free data updates daily, not real-time, so intraday use is not viable.
Which AI stock screeners include options flow data?+
None of these 7 tools natively include genuine unusual options flow data at their base price. Finviz Elite shows a basic options chain view but has no unusual-activity filter. Trade Ideas and TrendSpider have no options flow at all. If options flow is central to your process, you need a separate dedicated options flow platform (Unusual Whales at $50/mo, BlackBoxStocks at $99/mo) and pair it with your stock screener. This is a notable gap in the current AI stock screener market.
Why are Bloomberg Terminal or Reuters Refinitiv not included?+
Bloomberg Terminal runs roughly $25,000+/year; Refinitiv Eikon is similar. Both are institutional products and not comparable to retail tools on a reasonable budget. This comparison focuses on what individual traders and investors can actually afford ($0-$250/mo) with public pricing and direct online signup. If you work in an institutional setting with Bloomberg access, none of these 7 tools compete on data depth and this page will not be useful to you.
