Best AI Robo-Advisor Alternatives for a 401(k) Rollover in 2026

Last updated June 2026

Short answer

When you roll a 401(k) into an IRA, the real choice is how you want it managed. Hands-off robo-advisors (Betterment, Wealthfront, SoFi, Fidelity Go) open the IRA, take the transfer, and run a diversified portfolio for you, usually for a small management fee. AI assistants and self-directed setups keep you in control: Walnut is an AI investing assistant that connects the rollover IRA you open at a broker (read-only by default) and lets you ask about real holdings through Claude or ChatGPT. There is no single best one; match it to how hands-on you want to be, and weigh fees over a long horizon. Walnut is not an investment adviser.

Rolling an old 401(k) into an IRA is the easy part. The harder question is what to do with the balance once it lands, often as a lump sum of cash. You can hand it to a robo-advisor that invests and rebalances it on autopilot, you can keep it self-directed and make the calls yourself, or you can sit somewhere in between with an AI assistant that helps you understand and shape it without taking over. This guide covers six options (Betterment, Wealthfront, SoFi, Fidelity Go, Empower, and Walnut), describes each on the same fields, leads with the hands-off robos because they fit the most common rollover, and is honest about where each one, including Walnut, is the wrong fit.

The three ways to manage a rollover

Before the brand names, it helps to name the three jobs, because the whole decision turns on which one you want:

Hands-off robo-advisors (Betterment, Wealthfront, SoFi, Fidelity Go). They open the IRA, accept the rollover, and build and rebalance a diversified portfolio for you automatically, usually for a management fee. You decide your risk level; they handle the rest.
Planning and hybrid services (Empower). Tools to see your whole financial picture, plus an optional human-plus-managed service for larger balances. Useful for the planning side of a rollover.
Self-directed with AI help (Walnut). You open and fund the IRA at a broker and stay in control of the holdings, with an AI assistant grounded in your real positions to help you understand and shape the balance. Not hands-off, and not a manager.

A robo makes the calls for you. A self-directed setup keeps the calls yours. Both are reasonable; they answer different questions about how involved you want to be.

Hands-off robo-advisors: Betterment, Wealthfront, Fidelity Go, and SoFi

For the most common rollover, where you just want the balance invested and looked after, the automated robos are the natural fit. They open the IRA, take the transfer, and run a diversified ETF portfolio at your chosen risk level. The trade-offs are consistent: you do not pick the holdings, and most charge an ongoing management fee (commonly around 0.25% a year) on top of fund costs.

Betterment

One of the original automated robo-advisors. You open an IRA, answer a few goal-and-risk questions, and it builds and rebalances a diversified portfolio of low-cost ETFs for you, with automatic deposits and tax features layered on. It is built to take a rollover and run it hands-off.

Best for: A hands-off rollover where you want a diversified, automatically rebalanced portfolio without picking anything yourself.
Rollover fit: Strong (opens the IRA, takes the transfer, manages it).
The catch: It is intentionally a black box: you do not choose individual holdings, you pay a management fee (commonly around 0.25% a year) on top of fund costs, and there is little room to express your own themes or convictions.

Wealthfront

A fully automated robo-advisor in the same mold as Betterment, known for its automation and planning tools. You open an IRA, set a risk level, and it invests a rolled-over balance into a diversified ETF portfolio and keeps it rebalanced, with automated tax features on taxable accounts.

Best for: A hands-off rollover with strong automation and planning, for someone who wants the whole thing run for them.
Rollover fit: Strong (opens the IRA, takes the transfer, manages it).
The catch: Like any robo it is hands-off by design, charges a management fee (commonly around 0.25% a year) on top of fund expenses, and gives you little say over the specific positions, so it is the wrong fit if you want control.

Fidelity Go

Fidelity’s robo-advisor, run inside the same brokerage many people already roll a 401(k) into. You open a Fidelity IRA, and Fidelity Go builds and manages a diversified portfolio of Fidelity funds, with no advisory fee below a stated balance threshold and a flat structure above it.

Best for: Rolling into a major custodian you may already use and letting its robo manage the balance, often with no advisory fee at smaller sizes.
Rollover fit: Strong (rollover and robo under one familiar custodian).
The catch: It is still hands-off, the lineup is Fidelity’s own funds, and the fee structure changes once you cross the balance threshold, so check the current terms for your rollover size before relying on the no-fee tier.

SoFi

A consumer finance app that bundles an automated investing robo with banking, loans, and member perks. You can roll a 401(k) into a SoFi IRA and have its automated portfolios manage the balance, often with low or no management fee, inside an app you may already use for other money.

Best for: A hands-off rollover for someone who wants investing alongside the rest of their money in one consumer app, often at a low or no management fee.
Rollover fit: Good (IRA plus low-cost automated investing in one app).
The catch: It is built for breadth across many products rather than depth in investing, the automated portfolios are still hands-off, and it is not the place for deep single-position research or expressing your own themes.

The practical takeaway: these are the right call when you want the rollover handled and would rather not think about it. They are the wrong call if you want to choose your own positions or avoid an ongoing management layer over the decades an IRA may sit invested.

Planning and hybrid: Empower

Empower sits a little apart. Its free tracking and retirement tools are useful for seeing your whole picture before and after a rollover, and its paid advisory tier pairs human advisors with managed portfolios for people who want a higher-touch service on a larger balance.

Empower

A planning and wealth-management platform with free portfolio and retirement tracking tools, plus a paid advisory service that pairs human advisors with managed portfolios. The free tools are useful for seeing a whole financial picture before and after a rollover.

Best for: Whole-picture retirement planning, and a higher-touch managed service if you want human advisors involved in a larger rollover.
Rollover fit: Good for planning; managed tier suits larger balances.
The catch: The free side is tracking and planning, not management, and the paid advisory tier typically targets larger balances at advisory fees well above a pure robo, so it is overkill for a small, simple rollover.

This is the right call when planning across many accounts matters more than the cost of any single one, or when a larger rollover justifies human advisors. It is overkill for a small, simple rollover that a low-cost robo or a self-directed IRA would handle just as well.

Self-directed with AI help: Walnut

To be upfront, since this is our site: Walnut is the self-directed-with-AI kind, and it leads in that narrow category rather than overall. It is not a robo-advisor and it is the wrong tool if you want the balance managed for you. Walnut is an AI investing assistant you chat with on the broker you already own. After you open and fund a rollover IRA at a supported broker, Walnut connects it through SnapTrade and lets you ask about what you actually hold.

Walnut

An AI investing assistant you chat with on the broker you already own. After you open and fund a rollover IRA at a supported broker, Walnut connects it through SnapTrade (read-only by default) and lets you ask about your real holdings by talking through Claude, ChatGPT, or a built-in assistant, with web search and each position framed against the S&P 500.

Best for: A self-directed rollover where you want AI help understanding and shaping the balance yourself, rather than handing it to an automated manager.
Rollover fit: Self-directed (connects the IRA you open; you stay in control).
The catch: It is not hands-off and does not manage money for you: Walnut does not custody funds or process the rollover itself, you open and fund the IRA at a broker, it frames returns as window returns because broker feeds rarely pass cost basis, and every trade needs your approval.

The distinctive part is that the chat knows your real positions, frames each one against the S&P 500, and can turn research into a thematic basket you act on at your own broker. Walnut does not custody money and does not process the rollover itself: you open and fund the IRA, it connects read-only by default, every trade needs your approval, and because broker feeds rarely pass cost basis it frames returns as window returns rather than realized profit and loss, and says so. Walnut is not an investment adviser.

Rollover-specific factors that actually matter

Choosing a tool is only half of it. A rollover has its own decisions, and they shape which option fits:

Where to roll it. Most people move an old 401(k) into an IRA at a brokerage for more choice and often lower cost than the old plan. A direct, trustee-to-trustee transfer avoids the withholding and deadlines an indirect rollover can trigger. See the IRA versus 401(k) comparison and what a 401(k) is for the basics.
What to do with the lump sum. A rollover often arrives as cash. A robo invests it automatically; self-directed, you decide how and when, and some people stage it in rather than all at once.
Automation versus control. Automation removes effort and emotion and keeps you invested; control lets you express your own views and avoid an ongoing fee, but asks for your attention. Pick the one you will actually stick with.
Fees over a long horizon. A management fee is small in one year but compounds over the decades a rollover sits invested, on top of fund costs. Weigh it against the value of automation for you.
Account type and tax. A traditional 401(k) usually rolls to a traditional IRA; converting to a Roth is a taxable event. Confirm the rollover type and any tax implications before moving money.

Which to use for what

The fastest way to choose is to name how hands-on you want to be, then pick the option built for that. There is no overall number one; Walnut leads only in its own category (AI help for a self-directed rollover), not across the board.

You want the balance managed for you. Betterment and Wealthfront are the classic automated robos; Fidelity Go suits rolling into a custodian you already use; SoFi bundles it with the rest of your money.
You want whole-picture planning or human advisors. Empower’s free tools track everything, and its managed tier suits a larger, higher-touch rollover.
You want to stay in control with AI help. Walnut connects the IRA you open through SnapTrade and lets you research what you hold through Claude or ChatGPT, framed against the S&P 500.
You are unsure how hands-on to be. Start by tracking with Empower or asking questions in Walnut, then decide whether you want to hand the balance to a robo.

How to choose for a rollover

Once you know how hands-on you want to be, a few practical filters narrow it the rest of the way:

Hands-off or hands-on? If you want it managed, a robo (Betterment, Wealthfront, Fidelity Go, SoFi) is the fit. If you want control, a self-directed IRA with AI help like Walnut keeps the calls yours.
What does it cost over decades? Compare the ongoing management fee, not just year one. A small percentage compounds over a long-horizon retirement balance, on top of fund costs.
Where does the money live? Robos and brokers custody your funds under regulation. Walnut never custodies money and connects read-only by default through SnapTrade, with your approval for any trade.
Does it fit your existing accounts? Rolling into a custodian you already use (Fidelity, SoFi) can simplify things; a self-directed IRA at any major US broker can connect to Walnut without moving accounts.
Does it stay descriptive? A trustworthy tool explains and frames trade-offs without pretending to be your adviser. Be wary of anything promising guaranteed market-beating returns.

The bottom line

There is no single best way to manage a 401(k) rollover, because the options answer different questions. If you want the balance invested and looked after, the hands-off robos (Betterment, Wealthfront, Fidelity Go, SoFi) open the IRA, take the transfer, and run it for you, usually for a small management fee. Empower helps you plan the whole picture and offers a managed tier for larger balances. Walnut is the self-directed option with AI help: it connects the rollover IRA you open, lets you ask about real holdings through Claude or ChatGPT, frames each position against the S&P 500, and keeps every trade in your hands. Pick by how hands-on you want to be, and weigh the fees over the long horizon a rollover sits invested. Walnut is not an investment adviser.

FAQ

What is the best robo-advisor for a 401(k) rollover?

There is no single best one; it depends on how hands-off you want to be. Betterment and Wealthfront are the classic automated robos that open the IRA, take the transfer, and manage it for you. Fidelity Go is strong if you are rolling into a custodian you already use, and SoFi bundles it with the rest of your money. If you would rather stay in control, Walnut is an AI assistant for a self-directed rollover. Walnut is not an investment adviser.

Should I roll my 401(k) into a robo-advisor or do it myself?

It comes down to whether you want the balance managed for you or want to make the calls. A robo-advisor like Betterment, Wealthfront, Fidelity Go, or SoFi builds and rebalances a portfolio automatically, which suits people who want it handled. A self-directed IRA with an AI assistant like Walnut keeps you in control, with help understanding what you own. Neither is right for everyone; match it to how involved you want to be.

Is Walnut a robo-advisor?

No. A robo-advisor opens an account, takes your money, and manages a portfolio for you on autopilot. Walnut does none of that: it does not custody money or process a rollover, it connects the IRA you open at a broker (read-only by default through SnapTrade), and it helps you research and shape the balance yourself while you approve every trade. It is an AI investing assistant for a self-directed rollover, and it is not an investment adviser.

Where should I roll my 401(k)?

Most people roll an old 401(k) into an IRA at a brokerage, which usually gives more investment choices and often lower costs than leaving it in the old plan. Where exactly depends on whether you want a robo to manage it (Betterment, Wealthfront, Fidelity Go, SoFi) or a self-directed IRA you control. If you go self-directed, you can open the IRA at a major broker and connect it to Walnut for AI help. Check current rollover rules and any tax implications before you move money.

What should I do with the lump sum after a rollover?

When a 401(k) lands in an IRA it often arrives as cash, and you decide how to invest it. A robo-advisor invests the lump sum automatically into a diversified portfolio at your chosen risk level. Self-directed, you choose how and when to put it to work, and some people stage it in rather than all at once. Walnut can help you think through a self-directed balance, but it is not an investment adviser and the decision is yours.

Are robo-advisor fees worth it over a long horizon?

A robo management fee (commonly around 0.25% a year) is small in any single year but compounds over the decades a rollover may sit invested, on top of the underlying fund costs. For many people the automation, rebalancing, and discipline are worth it. If you would rather not pay an ongoing management layer and are willing to manage the balance yourself, a self-directed IRA with an AI assistant like Walnut avoids that fee, though you take on the work. Always verify current fees on each provider’s site.

Automation or control: which matters more for a rollover?

Both are valid, and the honest answer is it depends on you. Automation (a robo) removes effort and emotion: it rebalances and keeps you invested without you touching it. Control (self-directed) lets you express your own views and avoid an ongoing fee, but it asks for your attention and discipline. Walnut sits on the control side with AI help, so you stay hands-on but not alone. Pick the one you will actually stick with.

Can I keep my rollover at a broker I already use?

Often yes. Many brokers offer both a self-directed IRA and an in-house robo, so you can roll into a custodian you already trust. Fidelity Go is an example of a robo run inside a major brokerage. If you go self-directed at any major US broker, Walnut connects that IRA through SnapTrade so you can ask about the holdings through Claude or ChatGPT without moving accounts. Confirm your broker accepts the rollover type you have.

Is there a free option for managing a rollover?

Some robos waive the management fee below a balance threshold (Fidelity Go is one example) or keep it low (SoFi), though you still pay underlying fund costs. Empower’s tracking tools are free, but its managed service is not. Walnut has a free tier for connecting and asking about your holdings, since it is an assistant rather than a manager. Free tiers and thresholds change often, so check current details before relying on them.

Does Walnut process the rollover for me?

No. Walnut does not custody money or move a 401(k) into an IRA. You open and fund the rollover IRA at a supported broker yourself, and Walnut connects to it afterward (read-only by default through SnapTrade) so you can ask about the real holdings and frame each against the S&P 500. It is the intelligence layer on top of the account, not the account itself, and it is not an investment adviser.

What is the safest way to handle a 401(k) rollover?

The mechanics matter: a direct (trustee-to-trustee) rollover avoids the withholding and deadlines that can come with an indirect one, so most people move the money directly into the new IRA. After that, safety is about access and control. Robos and brokers custody your money under regulation; Walnut never custodies it and reads your holdings read-only by default, requiring your approval for any trade. Confirm the rollover process with both plan administrators and verify each provider’s security model.

Can an AI help me decide how to invest a rollover?

It can help you understand and frame the decision, but giving regulated investment advice is a line most consumer tools do not cross. Walnut helps you research, see how holdings compare to the S&P 500, and shape a self-directed balance into thematic baskets, while staying descriptive. It is informational and is not an investment adviser; the decision and any trade are yours. For a fully managed alternative, a robo-advisor makes the calls for you instead.

Walnut is informational and is not an investment adviser. App features, pricing, and availability change; verify current details on each provider's site before deciding. Nothing on this page is a recommendation to buy, sell, or hold any security or to use any particular product.
