Can AI Be Your Wealth Manager?

When someone says they have a wealth manager they usually mean one relationship covering investments, tax coordination, retirement planning, estate work, and somebody to call. Priced together, delivered together, and charged as a single percentage of what you own. That bundling is why the question is hard: the parts have very different answers.

Unbundle it and the decision gets much easier, because you can buy the parts you need from whoever does them best. Some are now effectively free. Some cost a fraction of what the bundle does. A couple are still worth paying a person properly for, and paying once rather than every year.

The six jobs below are our grouping, not an industry standard, and the middle column is our read of where the software genuinely is in 2026 rather than where it is marketed to be.

Two of these decide the question, because they are about who is accountable to you rather than about what the software can compute.

• SEC, Staff Bulletin: Standards of Conduct for Broker-Dealers and Investment Advisers, Care Obligations. Read it. Sets out the care obligations that apply to broker-dealers under Regulation Best Interest and to investment advisers under the fiduciary standard of the Investment Advisers Act of 1940. Both are drawn from fiduciary principles that include acting in the retail investor's best interest and not placing the firm's interests ahead of the investor's.
• CFP Board, Code of Ethics and Standards of Conduct. Read it. The standards a CERTIFIED FINANCIAL PLANNER professional agrees to, including a duty to act as a fiduciary when providing financial advice to a client.
• Investor.gov (SEC Office of Investor Education and Advocacy), Robo-Adviser. Read it. Defines a robo-adviser as an automated digital investment advisory program that collects your goals, horizon, income, assets and risk tolerance through an online questionnaire, then creates and manages a portfolio for you, often at lower cost than a traditional advisory programme.

The practical upshot is that the difference between a wealth manager and a tool is not mainly capability, it is duty. A registered adviser owes you a legal standard of care and can be held to it. An informational tool, including Walnut, owes you accuracy and honesty and is not a fiduciary. That distinction is worth more than any feature comparison when the decision is large.

Rough shapes rather than a price list, because specific numbers change and every provider should be verified directly. The shapes are what matter for the decision.

• Traditional wealth management: commonly around 1% of assets a year, sometimes lower at larger balances. On a long horizon this is the largest number on the page, and it buys the whole bundle including the two jobs software cannot do.
• Fee-only or hourly planner: a flat annual or per-project fee. Often the best value for a one-time question, because you are buying the judgment without renting it forever.
• Robo-advisor: commonly around 0.25% a year plus fund expenses. Covers allocation and rebalancing, and in taxable accounts the mechanical tax work.
• AI assistant on your own account: often free, covers the knowing-what-you-own job, and manages nothing.

The comparison people get wrong is paying an ongoing percentage to answer a one-time question. If what you actually need is a Roth conversion decision or a plan for a windfall, a flat-fee engagement usually costs a fraction of a year of the alternative, and you can repeat it when something changes.

The gap between roughly 1% and roughly 0.25% reads as three quarters of a percent, which sounds trivial. The reason it is not is that a percentage fee is charged on the entire balance every year, including everything the balance has grown into, so it scales with exactly the thing you are trying to accumulate.

Here is the arithmetic, stated as arithmetic and not as a prediction. Take a balance that compounds at some rate before fees. A 1% annual fee does not cost you 1% of the final number; it removes 1% of every year's balance, and the money removed early would itself have compounded for the remaining decades. Over a thirty year horizon, the difference between paying 1% and paying 0.25% is commonly in the region of a fifth of the final balance, depending entirely on the growth rate you assume. That is not a claim about returns, which nobody can promise. It is a claim about how a proportional fee interacts with compounding, which is fixed.

Two honest counterweights, because the arithmetic on its own is misleading. First, the comparison is only fair if you would actually do the job yourself, and a large share of people who intend to rebalance do not. Second, the fee buys the two things on this page software cannot do, so comparing 1% against 0.25% compares a bundle against a component. The fair comparison is 1% against 0.25% plus whatever you would separately pay for planning and coaching, and for a lot of people that gap is much smaller than it first looks.

If you do decide you want a person, these five separate the ones worth paying from the ones who are selling you a portfolio you could have bought yourself. Ask them in writing.

• Are you a fiduciary at all times, and will you say so in writing? The qualifier matters. Some people are held to a fiduciary standard for part of what they do and a lower standard for the rest, which is exactly the situation where you want it on paper.
• How are you paid, and by whom? A percentage of assets, a flat fee, commission on products, or some combination. The question behind it is what happens to your adviser's income if you pay off your mortgage or buy an annuity instead of investing.
• What is actually included? Get the six jobs named specifically. Plenty of relationships priced as wealth management are allocation and rebalancing with an annual review, which is a robo-advisor with a phone number.
• Who else is in the room? Coordination is a genuine part of the value, so ask whether they work with your accountant and an estate attorney or hand you a referral and step back.
• What happens in a 30% drawdown? The answer you want describes a process and a conversation, not a prediction about markets. This is the coaching job, and it is the one you are least able to evaluate afterwards, so evaluate it up front.

Traditional wealth management often sets a minimum balance, and the reason is arithmetic rather than snobbery: a percentage fee on a small account does not fund a human relationship. That is a real barrier and it is the clearest thing software has changed. Robo-advisors commonly accept small balances and an assistant reading an account you already have typically has no minimum at all.

The trap at the small end is fee shape. A percentage fee stays proportional as your balance falls. A flat monthly subscription does not: the same charge is a rounding error on a large account and a serious drag on a small one, and several consumer products priced that way are aimed squarely at small balances. Convert any flat fee into a percentage of your actual balance before comparing it to anything.

• Write down the actual question. Not “should I get a wealth manager” but the specific thing you want resolved. Most people find it is one or two items from the six above.
• Answer the free ones first. Knowing what you own and whether you are concentrated costs nothing now, and it often changes the rest of the conversation.
• Buy judgment for the hard ones, once. A fee-only planner for the specific decision, rather than an ongoing percentage.
• Be honest about the coaching job. If you know you would sell in a crash, that is worth paying for and no tool solves it. If you would hold, you are paying for discipline you already have.

Related reading: AI financial advisor versus a human financial advisor goes deeper on the comparison, and what an AI managed portfolio actually is covers the delegated-authority option.

Walnut covers the first job on the list and none of the others. It connects the brokerage account you already have, read-only by default, and answers questions about what is actually in it: concentration, overlap, how a position has done against a benchmark. That is the knowing-what-you-own job, which is the one people most often pay a percentage of assets for and the one software does best.

It does not manage money. It does not model retirement income, withdrawals or Social Security. It does no estate planning. It does not make strategic tax calls. And it is not a fiduciary or a registered investment adviser, so nobody at Walnut is legally accountable for your outcome. If your question is one of the other five, this is the wrong tool and a fee-only planner is a better use of your money.
