'AI-powered' robo-advisors: what the AI actually does, and what you pay for it
Robo-advisors were automating portfolios long before chatbots. Now many add 'AI' to the pitch. We sorted what is rules-based automation, what is generative AI, and what the fees look like on the firms' own pages.
Ask a robo-advisor what its AI does and you will often get a vague answer. A September 3, 2026 guide by Radlof, built on the firms' own fee pages and regulatory filings, puts it plainly: at the big US services, the 'AI' is mostly rules-based software, and generative AI shows up at the edges. That distinction matters because it tells you who decides what you own.
Three different things sold as 'AI'
- Classic robo-advisor. You answer a questionnaire; software buys a model portfolio, rebalances and harvests tax losses. The firm's investment team designs the models. Examples: Betterment, Wealthfront, Schwab Intelligent Portfolios, Vanguard Digital Advisor.
- Human-run portfolio with AI summaries. Radlof cites Robinhood Strategies' advisory brochure: the portfolio team makes investment decisions, and generative AI 'Digests' summarize news and data about your holdings. Robinhood says it does not use AI to make investment decisions, and does not review every Digest before it goes out.
- Prompt-built portfolios. You type a theme; AI agents screen stocks and weight them into an index you can invest in. Radlof cites Public's Generated Assets as the example, and notes Public says the output is not a recommendation and suitability is your responsibility.
Only the third puts AI anywhere near stock selection, and in that case you are the one approving the basket.
What the fees look like (read October 14, 2026)
| Service | Advisory fee | Minimum or condition |
|---|---|---|
| Betterment | $5 a month, or 0.25% a year | 0.25% applies with $200+ monthly deposits or $24,000+ balance |
| Wealthfront | 0.25% a year | Per its pricing page |
| Schwab Intelligent Portfolios | No advisory fee | $5,000 minimum; part of the portfolio held in cash at Schwab Bank |
| Fidelity Go (as listed by Schwab) | None under $25,000; 0.35% above | Comparison table on Schwab's page |
Sources: Betterment pricing, Wealthfront pricing, Schwab Intelligent Portfolios. Radlof's table adds Robinhood Strategies at 0.25% a year, with Gold members paying it only on the first $100,000 per account; we did not open Robinhood's page for that figure Context: n: not applicable, list price · guide dated Sep 3, 2026 · Radlof, citing Robinhood · margin: not applicable.
Two cost notes. 'No advisory fee' is not free: Schwab's own page says investors pay ETF operating expenses and that a portion of each portfolio sits in an FDIC-insured deposit at Charles Schwab Bank, and Radlof cites Schwab's fact sheet saying affiliates earn money from those ETFs and that cash. And Betterment's flat $5 is a bigger share of a small account: on $10,000 it is $60 a year, or 0.6%, versus $25 at 0.25%, as Radlof works out Context: n: not applicable, arithmetic on list prices · Sep 3, 2026 · Radlof · margin: not applicable.
Where generative AI actually helps
The generative layer is mostly explanation: why your portfolio moved, which holdings drove it, what a concentration means. Investors are already using chatbots for this on their own. Betterment's advisor unit surveyed 1,001 US investors who work with a financial advisor; 75% said they used AI at least occasionally for financial questions Context: n=1,001 US investors who work with an advisor · published Sep 10, 2026, fieldwork dates not disclosed · Betterment Advisor Solutions survey · margin: not disclosed.
The red flag regulators already punished
On March 18, 2024 the SEC settled charges against two advisers for 'AI washing'. Delphia claimed it used AI and machine learning on client data to predict winning companies; the SEC found it did not have those capabilities. Global Predictions called itself the 'first regulated AI financial advisor' and advertised 'expert AI-driven forecasts.' The firms paid $225,000 and $175,000 in civil penalties, without admitting or denying the findings.
The practical lesson: an AI claim in an adviser's marketing is a statement you can check. Form ADV Part 2, the plain-language brochure every registered adviser files, says how the firm is paid and, increasingly, where it uses AI.
Questions to ask before you fund one
- Who decides what I own? The firm's model, a human team, or me approving an AI-built basket?
- What is the all-in cost? Advisory fee plus fund expenses plus any required cash allocation.
- Is tax-loss harvesting worth it for me? Both Betterment and Wealthfront pitch it as paying for the fee, based on their own calculations; it does nothing inside an IRA or 401(k).
- What does the AI summary get wrong? If the firm does not review every AI-written note, treat it as a draft.
What it shows / What it doesn't
It shows
- That at the large US robo-advisors, investment decisions come from rules-based models or human teams, with generative AI used mainly for explanations.
- Advisory fees as published on Betterment, Wealthfront and Schwab pages on October 14, 2026.
- That regulators have already penalized advisers for overstating their AI.
It doesn't show
- Performance. We compare what the AI does and what it costs, not returns, which depend on the portfolio mix and the period.
- Total cost for any specific account, which includes fund expenses and cash allocations not shown in the fee table.
- Robinhood Strategies' fee from Robinhood's own page; that figure comes from the Radlof guide.
- How accurate any firm's AI-written summaries are. We found no published test.
Why it matters
If you want the AI to do the homework, a robo-advisor already automates the boring, valuable parts: rebalancing and staying invested. Paying extra for 'AI' only makes sense if you can say what it decides, and the choice of service, and of risk level, remains yours.
