Best AI Investing Apps for ETF Investors (2026), Compared

Federico Kunze Küllmer is the founder of Moneda, one of the tools compared here.

Short answer: If you mostly buy ETFs, pick an app whose AI can explain what a fund holds, show you where each number came from, and let you invest in the same place. Moneda AI suits that if you want sourced research and a portfolio you can stress-test. Composer suits people who want to automate rules. Robinhood Gold and Public suit people who already use those brokers. Seeking Alpha and Fiscal.ai are research tools, not places to trade.

• Best overall for ETF investors: Moneda (Standard free, Premium from €9.99/month). Shows the source behind each figure, gives a bull and bear case, and lets you invest in the same app.
• Best for automated, rule-based strategies: Composer (Starter $0, Advanced $10/month)
• Best for turning an idea into a custom index: Public (price not published) Best low-cost add-on for Robinhood users: Robinhood Gold with Cortex ($5/month)
• Best for ratings and community analysis: Seeking Alpha Premium (price not published)
• Best for plugging financial data into Claude or ChatGPT: Fiscal.ai (price not published, 7-day free trial)

An ETF (exchange-traded fund) is a basket of stocks, bonds or commodities that trades on an exchange like a single share. ETFs are popular because one purchase spreads your money across many holdings. The catch is that two funds with similar names can hold very different things and charge very different fees. AI tools can help you read past the label. They differ a lot in how much they show their working.

We compared six apps using each vendor's own website, read on 23 October 2026. We did not open accounts or test them hands-on. Where a vendor's page did not state something, we say so.

What to look for

Here is what matters most if your portfolio is mainly funds.

• Fund-level detail. Can the AI tell you what an ETF actually holds, how concentrated it is and what it costs? A tool built only around single stocks will struggle here.
• Sources you can check. An AI answer is only as useful as your ability to verify it. Look for apps that link each figure back to a filing or a data feed.
• Both sides. Good research gives you the case for and against. Be wary of anything that only cheers.
• Portfolio testing. ETF investors care about how the whole mix behaves. Stress tests against past crashes and benchmark comparisons help more than a single fund score.
• Where you trade. Research in one app and trading in another means copying tickers around. That is fine for some people. Others want one place.
• Control. You should approve every trade. No app should place orders you did not confirm.
• Clear pricing. Several vendors in this list do not publish prices on their main pages. That makes comparing harder, so check before you commit.

The apps

Moneda

What it is. Moneda is an investing app for mobile and web, built in Berlin. Moneda AI, the agent inside it, runs on Numa 1, Moneda's financial AI engine.

What the AI does. The agent researches stocks, ETFs, crypto and a few commodities held through ETFs (gold, silver, oil). It works figures out from company filings and live market data, and shows the source behind each one. It gives you the bull case and the bear case. For companies it scores the 7 Powers, a framework for judging a moat (a lasting edge that keeps competitors out), and checks quality of earnings, meaning whether reported profit is backed by real cash. The Moneda Ratio is a descriptive 1 to 7 scorecard. A stock screener lets you filter by the numbers you care about, and each day the agent sends a briefing on your portfolio and the market.

For ETF investors, the portfolio side is the useful part. Describe an idea in plain words and the agent finds matching investments. Give it a goal and it builds an illustrative portfolio, tracks it and tells you when something changes. You can stress-test that portfolio against 2008, 2020 and 2022, and benchmark it against gold, an index or any fund.

You can invest in the same app: fractional US-listed shares and ETFs, plus crypto. You approve every trade with your passkey (face or fingerprint). The agent never tells you to buy or sell. Moneda MCP connects Claude and ChatGPT to your account with permissions you set, so you choose what each agent can see and do. Payments are still approved in the app. Premium and Ultra add a REST API and a CLI.

In Moneda's own tests in October 2026, the agent scored 97.9% on groundedness, 92% on claim verifiability and 95.6% on FLARE-CFA. On the public set of the Vals AI Finance Agent Benchmark v2 it scored 80%, run and graded by Moneda. Vals AI's top published score is 65.4%, but that is on its private set, a different set of questions.

Data covered. Company filings, such as the 10-K (the annual report US companies file with the SEC), and live market data across stocks, ETFs and crypto.

Price. Standard is free. Premium starts at €9.99/month. Ultra starts at €19.99/month, with more AI usage and 1, 5 or 10 commission-free trades a month depending on the tier.

Best for. ETF investors who want to research and invest in one app, including gold, silver and oil through ETFs, researched before you buy, with your approval on every trade.

One honest limitation. You can only buy US-listed shares and ETFs, so no European-listed ETFs.

Composer

What it is. Composer is an automated investing platform. You build strategies in a no-code editor, backtest them and let them run. Composer Securities LLC is the broker-dealer.

What the AI does. "Trade with AI" helps you find and evaluate strategy ideas. Higher plans get more weekly AI usage.

Data covered. Not documented on the pricing page. The page does not mention ETFs.

Price. Starter is $0/month. Advanced is $10/month. Pro is $32/month billed yearly ($384/year). Business pricing needs a call.

Best for. People who think in rules, such as "rebalance between these funds when X happens", and want those rules run for them.

One honest limitation. The pricing page says little about how the AI works or which assets it covers, so you will need to dig further before relying on it for ETFs.

Public

What it is. Public is a brokerage app. Its site lists ETFs as an asset class, described as baskets of assets.

What the AI does. Alpha is described as "an experimental AI research tool". Generated Assets lets you turn an idea into an index with AI, backtest it against the S&P 500 and invest in a few taps.

Data covered. Not documented for Alpha. The ETF references on the page are about Public's ETF trading, not about what Alpha covers.

Price. Price not published on the pages we read.

Best for. Investors who like the idea of building their own theme basket instead of buying an off-the-shelf ETF.

One honest limitation. Public itself says Alpha may give inaccurate responses and is not investment research, so you have to check its answers yourself.

Robinhood Gold (Cortex)

What it is. Gold is Robinhood's paid membership. Cortex is its AI feature.

What the AI does. Robinhood describes Cortex as investing intelligence that turns market data into insights. The page does not list specific features.

Data covered. Not documented on the Gold page. ETFs are not mentioned.

Price. $5/month, billed to your brokerage account every 30 days. The first 30 days are free.

Best for. People already investing with Robinhood who want AI insights for a small monthly fee.

One honest limitation. The public page gives very little detail on what Cortex does, so it is hard to judge for fund research before you sign up.

Seeking Alpha Premium

What it is. A research subscription with quant ratings, factor grades and articles from third-party authors.

What the AI does. Ask Seeking Alpha is described as an AI research assistant for going deeper on ideas. The page also lists AI-powered reports.

Data covered. The page says every stock is graded against its sector and updated daily. ETF coverage is not documented on that page.

Price. Price not published on the page we read.

Best for. Investors who want ratings and a wide range of written opinions in one place.

One honest limitation. It is research only. You cannot invest through it, and the authors are third parties who, as Seeking Alpha notes, may not be licensed.

Fiscal.ai

What it is. A financial data company offering a research terminal, an MCP connector and a data feed API.

What the AI does. The MCP product connects Fiscal.ai's financial data into your AI tools. The terminal is its research platform.

Data covered. Not documented on the pricing page.

Price. Price not published. The Terminal and MCP plans include a 7-day free trial.

Best for. People who already research in Claude or ChatGPT and want cleaner financial data inside them.

One honest limitation. There is no trading, and you have to sign up to see what you will pay.

How to choose

Start with where you want to trade. If you already have a broker you like, a research tool such as Seeking Alpha or Fiscal.ai may be enough. If you want research and trading together, compare Moneda, Composer, Public and Robinhood Gold.

Then ask how you invest. Rule followers will lean towards Composer. People who want to understand a fund and test a whole portfolio against past crashes will lean towards Moneda. Theme builders may like Public's Generated Assets.

Last, check what you can verify. ETF names can mislead. An app that shows its sources saves you from trusting a summary you cannot check.

FAQ

What is an AI investing app?

An app that uses AI to research investments, answer questions in plain language or help build a portfolio. Some also let you trade. None of the apps here should place a trade without your approval.

Can AI pick ETFs for me?

Some apps suggest ideas or build illustrative portfolios. Moneda AI, for example, finds ideas from a plain-language description but never tells you to buy or sell. The decision stays with you.

Do these apps cover European-listed ETFs?

It varies, and most vendor pages we read did not say. Moneda covers US-listed shares and ETFs only.

How do I know an AI answer is accurate?

Check the source. Look for apps that link figures to filings or data feeds, and compare against the fund's own factsheet. Terms like P/E (price divided by earnings per share) or free cash flow (cash left after running and investing in the business) should match the published numbers.

Are these apps free?

Some have free tiers: Moneda Standard and Composer Starter cost nothing. Robinhood Gold is $5/month. Several others do not publish prices on their main pages.

What is a DCF and do I need one for ETFs?

A DCF (discounted cash flow) estimates what a company is worth today from the cash it should make in future. It is a single-company tool. For ETFs, holdings, costs and how the fund behaved in past downturns usually matter more.
