Best AI Robo-Advisor Alternatives for ESG Investing in 2026
Last updated June 2026
Short answer
If you want a portfolio that reflects your values rather than a generic auto-allocated one, the useful question is not “which robo is best” but how much each tool lets you customize what you hold. The values-flexible options give you the most control: Walnut lets you design your own thematic baskets with AI on the broker you already own, and M1 Finance lets you hand-build a custom pie. If you would rather a robo manage it, Betterment and Wealthfront offer ready-made socially responsible (SRI) portfolios, while SoFi keeps it simple with limited values control, and Magnifi helps you discover ESG funds in chat. There is no single standard for what counts as ESG, so read what is actually screened. Walnut is not an investment adviser.
A standard robo-advisor is built to take your hands off the wheel: answer a few questions, and it auto-allocates and rebalances a diversified portfolio for you. That is great for simplicity, but it is the opposite of what many values-driven investors want, which is a say in what they actually own. So if you care about ESG, socially responsible (SRI), or thematic investing and you want AI to help, the right frame is how much each option lets you shape the portfolio. This guide covers six (Walnut, M1 Finance, Betterment, Wealthfront, SoFi, and Magnifi), describes each on the same fields, orders them by how much values customization they allow, and is honest about what ESG investing actually involves, including where each option, Walnut included, is the wrong fit.
What ESG and values-based investing involves
ESG investing means weighing environmental, social, and governance factors alongside financial ones when you decide what to hold. It overlaps with socially responsible investing (SRI) and the broader idea of values-based investing, and in practice it can take a few forms:
- Tilting toward companies or funds that screen well on a theme you care about, such as clean energy, climate, or labor practices.
- Excluding sectors you object to, the classic SRI move (for example tobacco, weapons, or fossil fuels).
- Thematic building, where you assemble a portfolio around a specific value or theme rather than a broad index.
The honest trade-offs matter as much as the appeal. There is no single standard for what counts as ESG: different providers use different data, methods, and exclusions, so two funds both labeled ESG can hold very different companies. Screening choices change what you hold and can narrow or concentrate a portfolio. Actively screened or thematic funds can carry higher costs than a plain index fund, and returns can differ from the broad market in either direction over any given window. None of this is a reason to avoid values-based investing; it is a reason to read what a given portfolio actually screens for and to decide which factors matter to you.
Values-flexible options: Walnut and M1 Finance
These give you the most control over what you hold, which is exactly what a generic robo does not. Walnut lets you design thematic baskets with AI on the broker you already own, and M1 lets you hand-build a custom pie that it then rebalances toward. In both, the values screen is yours to define rather than chosen from a menu.
Walnut
An AI investing assistant you chat with on the broker you already own. It connects your existing brokerage through SnapTrade (read-only by default) and lets you talk through Claude, ChatGPT, or a built-in assistant about your real holdings, with each position framed against the S&P 500. Because you design your own thematic baskets, you can build a values or ESG tilt yourself rather than picking from a fixed menu.
- Best for: Investors who want to design a values or thematic tilt themselves and talk it through with AI on their existing broker.
- Values customization: Full (you choose every holding).
- The catch: It is not a hands-off robo and not an ESG-screening engine: you design and approve every basket and trade, it does not auto-rebalance for you, and it does not apply a formal third-party ESG score, so the values screen is yours to define.
M1 Finance
A self-directed platform built around “pies”: visual portfolios of stocks and ETFs at target weights that M1 rebalances toward as you add money. You can build a fully custom pie from individual holdings or use expert pies, which makes it straightforward to assemble a values-aligned mix yourself.
- Best for: DIY investors who want to hand-build a values-aligned portfolio of stocks and ETFs and have it auto-rebalanced.
- Values customization: High (build any pie).
- The catch: It is not advice and not AI-driven: M1 gives you the tools and the automation, but the values screening, the security selection, and the judgment are entirely on you.
To be upfront, since this is our site: Walnut leads in this narrow lane (designing a values tilt with AI on your own broker), not across the board. It is not a hands-off robo and not an ESG-screening engine; you design and approve every basket and trade, it does not auto-rebalance for you, and it applies no formal third-party ESG score. The flexibility is the point, but it means the work and the judgment are yours. See the best AI investing apps for the wider field.
Managed robos with values options: Betterment, Wealthfront, and SoFi
If you would rather not pick individual holdings, the managed robos auto-allocate and rebalance for you, and some offer a values option on top. Betterment and Wealthfront both have socially responsible choices; SoFi’s automated tier is simpler and offers less values control.
Betterment
One of the largest robo-advisors. You answer goal and risk questions and it builds and auto-rebalances a diversified ETF portfolio for you. It offers dedicated socially responsible investing (SRI) portfolio options that tilt toward funds screened on broad ESG, climate, or social-impact themes.
- Best for: Hands-off investors who want a managed, auto-rebalanced portfolio with a ready-made SRI option.
- Values customization: Moderate (SRI portfolios, menu-based).
- The catch: Customization is bounded: you pick from its SRI portfolio menu rather than choosing individual holdings, and a managed robo typically charges an annual management fee (commonly around 0.25%) on top of fund expenses.
Wealthfront
A large automated robo-advisor that builds and rebalances a diversified portfolio from your risk profile. It offers socially responsible and customizable options, letting you add or weight ESG-oriented funds and exclude some categories within an otherwise automated allocation.
- Best for: Hands-off investors who want automation plus some ability to add ESG funds or exclusions to a managed portfolio.
- Values customization: Moderate (SRI options and exclusions).
- The catch: The customization sits inside an automated framework rather than full control, and like other managed robos it generally charges an annual management fee (commonly around 0.25%) above underlying fund costs.
SoFi Invest
SoFi’s automated investing builds and rebalances a goal-based ETF portfolio for you, bundled into a broader app that also covers banking, loans, and a self-directed brokerage. The automated tier is designed to be simple and low-friction rather than deeply customizable.
- Best for: Beginners who want a simple, low-cost managed portfolio inside an all-in-one money app.
- Values customization: Low (mostly preset allocations).
- The catch: The automated portfolios offer limited values customization; if you want a real ESG tilt you generally have to assemble it yourself through SoFi’s self-directed side, which moves the work back to you.
The trade is convenience for control: you get automation and, with Betterment or Wealthfront, a ready-made SRI tilt, but you pick from a menu rather than choosing each holding, and a managed robo typically charges an annual management fee (commonly around 0.25%) on top of fund costs.

Finance-specific discovery: Magnifi
Magnifi is neither a managed robo nor a portfolio you hold inside it; it is a conversational assistant for finding securities. That makes it a useful first step for ESG investing: discover the funds, then hold them somewhere else.
Magnifi
A conversational AI investing assistant built for markets. You ask plain-English questions about funds, ETFs, and stocks, and it helps you screen and discover securities, including ESG or thematic funds, with some account-connection features for context.
- Best for: Investors who want to discover ESG and thematic funds in plain-English chat before deciding what to hold.
- Values customization: Discovery only (helps you find funds).
- The catch: It is a discovery and screening assistant, not a managed robo and not a portfolio you hold inside it, so it helps you find values-aligned funds but does not build, hold, or rebalance the portfolio for you.
Use it when your question is “which ESG or thematic funds even exist for this” rather than “build and manage my portfolio.” Once you know what you want to hold, a values-flexible tool or a managed robo actually carries it.
Which to use for what
The fastest way to choose is to name how hands-on you want to be, then pick the tool built for that. There is no overall number one; the right fit depends entirely on how much control over your values tilt you want.
- You want full control over what you hold. Walnut lets you design thematic baskets with AI on your own broker; M1 lets you hand-build a custom pie. Both put the values screen in your hands.
- You want a robo to manage it, with a ready-made values option. Betterment and Wealthfront offer socially responsible (SRI) portfolios they auto-rebalance for you.
- You want simple and low-friction over deep customization. SoFi’s automated investing suits beginners, though values control is limited.
- You want to discover ESG and thematic funds first. Magnifi helps you screen and find funds in plain-English chat before you decide where to hold them.
- You want to talk your real holdings through with AI. Walnut connects the broker you already own (read-only by default) and lets you ask about what you hold through Claude or ChatGPT, framed against the S&P 500.

How to choose a values-based investing tool
Once you know how hands-on you want to be, a few practical filters narrow it the rest of the way:
- How much control do you want? If you want to choose every holding, a values-flexible option (Walnut, M1) fits; if you want it managed, a robo with an SRI menu (Betterment, Wealthfront) does.
- What does its values option actually screen for? Because there is no single ESG standard, read what a given SRI portfolio or fund holds and excludes rather than trusting the label.
- How does it handle costs? Managed robos typically add an annual management fee (commonly around 0.25%) on top of fund expenses; building it yourself lowers that layer but adds work. Verify current fees on each site.
- How does account access work? If a tool connects to your money, prefer regulated aggregation, read-only-by-default access, and explicit approval for any trade. Walnut uses SnapTrade and approves every trade with you.
- Does it stay descriptive? A trustworthy tool explains and frames trade-offs without promising guaranteed market-beating returns. Be especially wary of that around values or thematic funds.
The bottom line
There is no single best AI robo-advisor alternative for ESG investing, because the right one depends on how much control you want over what you hold. For full control, Walnut lets you design thematic baskets with AI on the broker you already own, and M1 lets you hand-build a custom pie. For a managed portfolio with a ready-made values option, Betterment and Wealthfront offer socially responsible portfolios; SoFi keeps it simple with less values control; and Magnifi helps you discover ESG funds before you decide. Go in clear-eyed: ESG definitions vary, there is no single standard, screening choices change what you hold, and values-tilted funds can cost more. Read what is actually screened, and pick by how hands-on you want to be. Walnut is not an investment adviser.

FAQ
What is the best AI robo-advisor alternative for ESG investing?
There is no single best one; it depends on how much control you want. If you want to design a values tilt yourself and talk it through with AI on your own broker, Walnut fits. M1 Finance lets you hand-build a custom pie. Betterment and Wealthfront offer ready-made SRI portfolios if you would rather a robo manage it, and Magnifi helps you discover ESG funds in chat. Match the tool to how hands-on you want to be. Walnut is not an investment adviser.
What is ESG investing?
ESG investing means weighing environmental, social, and governance factors alongside financial ones when you decide what to hold. In practice that can look like tilting toward companies that screen well on climate or labor practices, or excluding sectors you object to. It overlaps with socially responsible investing (SRI) and values-based investing, and the exact criteria differ from one fund or person to the next.
Is there a single standard for what counts as ESG?
No. There is no universal definition or single rating that everyone agrees on. Different providers use different data, methodologies, and exclusion rules, so two funds both labeled ESG can hold very different companies. That is why it pays to read what a given SRI portfolio or fund actually screens for, rather than trusting the label, and to decide which factors matter to you.
What are the trade-offs of ESG and values-based investing?
The main ones are that definitions vary and there is no single standard, that screening choices change what you end up holding (and can concentrate or narrow a portfolio), and that values-tilted or actively screened funds can carry higher costs than a plain index fund. Performance can differ from the broad market in either direction over any given window. None of this is a reason to avoid it, just to go in clear-eyed.
Can a robo-advisor do ESG investing?
Yes, to a point. Betterment and Wealthfront both offer socially responsible portfolio options that tilt toward ESG-screened funds, and they auto-rebalance them for you. The limit is customization: you usually pick from a menu of SRI portfolios rather than choosing individual holdings, so if you want precise control over what is in and out, a build-it-yourself option fits better.
How is Walnut different from a robo-advisor for ESG?
A robo auto-allocates and rebalances a managed portfolio, with an SRI menu if it offers one. Walnut is not hands-off: it connects the broker you already own (read-only by default), lets you ask about your real holdings through Claude or ChatGPT, and lets you design your own thematic baskets, so a values tilt is something you build and approve yourself rather than pick from a list. You approve every trade. Walnut is not an investment adviser.
Is Walnut an ESG fund or a screened portfolio?
No. Walnut does not apply a formal third-party ESG score or sell a pre-screened ESG portfolio. It is an AI assistant on top of your own brokerage that helps you research and lets you design thematic baskets, so any values or ESG screen is one you define yourself. That flexibility is the point, but it means the judgment about what counts as values-aligned is yours, not a vendor rating.
Do ESG robo-advisors cost more?
Managed robos like Betterment and Wealthfront generally charge an annual management fee (commonly around 0.25%) on top of the expense ratios of the funds they hold, and SRI or ESG funds can carry somewhat higher fund costs than plain index funds. Building it yourself on a broker can lower the management layer but moves the work to you. Verify current fees on each provider’s site before deciding.
Is ESG the same as SRI or values-based investing?
They overlap heavily and the terms are often used interchangeably, but they are not identical. SRI (socially responsible investing) historically emphasized excluding objectionable sectors, ESG emphasizes scoring companies on environmental, social, and governance factors, and values-based investing is the broad umbrella for aligning a portfolio with what you care about. The practical takeaway is the same: read what is actually screened, because the labels are loose.
Can I use AI to build a values-aligned portfolio?
Yes. Tools like Magnifi help you discover ESG and thematic funds in plain-English chat, and Walnut lets you research your real holdings through Claude or ChatGPT and design thematic baskets that reflect a theme or value you choose. AI can help you screen, compare, and reason through choices, but it does not remove the need to decide which factors matter and to verify what any fund actually holds.
Are these tools investment advisers?
It varies. Betterment, Wealthfront, and SoFi operate as registered advisers for their managed portfolios. Walnut is informational and is not an investment adviser: it helps you research, frames holdings against the S&P 500, and lets you design baskets, but the decision and any trade are yours. Always check how each provider is registered and what its service actually includes before relying on it.
Which option should I choose for ESG investing?
Decide how hands-on you want to be. For a hands-off managed portfolio with a ready-made values option, Betterment or Wealthfront SRI portfolios fit. For full control over what you hold, M1 lets you build a custom pie and Walnut lets you design thematic baskets with AI on your own broker. Magnifi helps you discover funds first. SoFi suits beginners who want simplicity over deep values control.
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.
