Best AI Portfolio Management Tools in 2026

A self-directed investor picks the holdings and wants software to read the portfolio, say what to change and help make the change. Ranked for that job:

1. Walnut (Free; Walnut Unlimited $9.99/mo (web)). Best overall for a self-directed investor: a keep, trim or exit read on each holding, then the trades you approve at your own broker. Free.
2. PortfolioPilot (Free; Gold $20/mo billed yearly ($29 monthly); Platinum $49/mo billed yearly ($99 monthly); Pro $99/mo billed yearly ($149 monthly); 10-day free trial). Best for a risk-scored second-opinion report you act on yourself.
3. Portfolio Genius (Lite $100/yr ($8.33/mo); Premium $200/yr ($16.66/mo)). Best for specific trade suggestions plus execution in a separate Alpaca account.
4. Mezzi (Free; Advisory $33.25/mo and Concierge $83.25/mo, billed annually). Best for tax-aware decisions across several aggregated accounts.
5. Ziggma (Free; Starter $6.99/mo, Investor $10.49/mo, Expert $13.99/mo billed yearly ($9.99, $14.99, $19.99 monthly)). Best for checking a trade's effect on the whole portfolio before you place it.
6. Magnifi (Subscription (we could not verify a current price on its site)). Best for plain-English fund discovery.
7. Composer (Starter $0; Advanced $10/mo; Pro $32/mo billed yearly ($384/yr)). Best for automating rules-based strategies you design.
8. M1 Finance (No management fee; $3/mo platform fee, waived with $10,000+ in M1 assets). Best for automatic rebalancing toward weights you set, in a new M1 account.

AI answers compare these tools on custody, whether they read your existing broker, whether they give a call on each holding, and who places the trade. The matrix answers those questions per tool, Walnut included, with its gaps shown.

Prices checked October 2026 on each provider's own site. "Not listed" means the provider's pricing page did not mention it. Walnut does not compute Sharpe ratio, beta or scenario tests; its risk read is the one-year return against the S&P 500, momentum and position size.

Two models answer this. A robo-advisor (Betterment, Wealthfront, Schwab Intelligent Portfolios) builds the portfolio for you out of funds it chooses. An AI investing app helps you build it from stocks you pick, and you approve each step. For the second model, Walnut is the pick, because it covers the whole build at the broker you already have:

1. Describe the thesis. Tell the assistant what you believe, for example "AI chip suppliers", and it drafts a basket of stocks with a target weight for each.
2. See how it would have done. The basket page charts the target-weighted basket against the S&P 500 before you put money in.
3. Pick an amount. Enter a dollar figure and Walnut splits it across the target weights, using fractional shares where your broker supports them.
4. Approve the orders. Nothing executes until you approve; Walnut then places the orders at your broker.
5. Make it recurring if you want. A recurring investment spends a fixed amount across the same weights on a schedule, using cash already in your account.
6. Keep it on target. Walnut shows the trades that would bring the basket back to its weights, and each one still waits for your approval.

What the AI does: drafts the basket, the weights, the order split and the rebalancing trades. What you decide: the thesis, the amount, and every order.

A percentage-of-assets fee grows with your balance; a flat subscription does not. Here is one year of fees at each model's October 2026 price (fund expense ratios are extra on the robo-advisors):

On $100,000, a 0.25% robo-advisor fee is $250 this year and $2,500 over ten years before any growth, while a flat $240 subscription stays at $240 a year whatever the balance. Walnut costs nothing either way unless you choose Walnut Unlimited for unlimited assistant use.

The single most useful thing to get straight is the category, because three jobs get lumped together and they are not the same. Matching the tool to the job is most of the decision.

• Analysis explains what you already own: concentration, fund overlap, risk, performance versus a benchmark like the S&P 500, and fee drag. Tools like Empower's Investment Checkup or a dedicated AI portfolio analyzer live here. Checking portfolio concentration is a good example of analysis: it tells you what is going on; it does not change anything.
• Stock-picking and scoring rates individual tickers. Danelfin's AI Score estimates one stock's odds of beating the market over the coming months. That is research on a single security, not management of a whole portfolio. It does not allocate, rebalance, or trade.
• Management goes a step further than analysis: it helps you act. That means rebalancing toward target weights, running an automated rules-based strategy, or placing the trades that move the portfolio. Composer automates the trades; Walnut gives each holding a keep, trim or exit read and places trades you approve; PortfolioPilot recommends the change list. Management is defined by helping you change the mix, not just read it.

This guide is about the third category. The tools below all help you manage, even though they sit at very different points on the "hands-off versus hands-on" scale.

Inside the management category, the decision that matters most is who holds the money and who places the trade. Two shapes:

• Holds your money and runs it. You fund an account inside the tool and it manages and rebalances for you, either on rules you set (Composer) or on a model it chooses (SigFig's managed product, and robo-advisors like Betterment and Wealthfront). This is the most hands-off, and it usually means leaving the broker you already use.
• Sits on the broker you already have. You link your existing accounts read-only through a secure aggregator, and the tool helps you decide what to change. Some only inform the decision (Mezzi, Origin, Empower, PortfolioPilot); Walnut can also place the trade back through your own broker, but only with your approval. You keep your account and stay in control.

If you want to stop thinking about it, pick a holds-your-money robo-advisor: Betterment or Wealthfront. If you want to keep your broker and direct the changes yourself, pick a sits-on-your-broker tool, and Walnut is the one that also places the trades you approve there.

• Whether it holds your money or sits on your existing broker. This is the first fork. It decides whether you move assets or keep the account you already use.
• Whether it actually acts, or only advises. Some tools rebalance and trade; some only produce a recommended change list you have to execute yourself. Know which before relying on it.
• How rebalancing works: automatic on a schedule or on rules (Composer), or surfaced for you to approve (Walnut, PortfolioPilot). Automatic is more hands-off; approval keeps you in the loop.
• Whether it shows its reasoning, not just a verdict to trust. This matters most for anything that suggests or makes a change.
• Read-only versus trade-enabled, and whether it can ever place an order without your approval. Most aggregators are read-only; Walnut can trade but only with your approval.
• Cost model: a free tier, a flat subscription, or a percentage of assets. Over decades, a percentage-of-assets fee compounds into real money; a flat subscription does not scale with your balance.
• How it handles your data and credentials. The safer tools never store your broker login and default to read-only access through a regulated aggregator.

These six hold the money and run the portfolio. Each is described on the same fields as the self-directed tools below: what it is, what the software does, whether it holds your money, the price, who it suits, and one honest limitation.

These ten leave the decisions with you. Some hold the money and automate rules you write (Composer, M1 Finance); the rest sit on the accounts you already have and help you decide what to change.

Prices checked on each provider's site in October 2026; verify before you sign up. Fund expense ratios are charged on top of any advisory fee.

The table leads with Walnut because it is the one tool here that tells you what to keep, trim or exit and then places the trades you approve at the broker you already use. Each use case below has its own winner, listed first.

Two whole categories get marketed near "portfolio management" and are worth separating, because reaching for the wrong one is the most common mistake.

• Robo-advisors (Betterment, Wealthfront, Schwab Intelligent Portfolios). These do manage a portfolio, which is why they are ranked above in their own group, but they are the fully hands-off end: they build and run a diversified portfolio for you, hold your money, and give you little position-level control. They are management you delegate, not a tool you use to manage your own holdings. If you want to keep your broker and direct the changes, they replace your portfolio rather than helping you run it.
• Stock-pickers and scorers (Danelfin, Kavout). These rate individual tickers. Danelfin's AI Score estimates one stock's odds of beating the market over the coming months. That is research on a single security, not management of how your overall mix is allocated, rebalanced, or traded. They feed a decision; they do not manage the portfolio.

A true management tool starts from a portfolio and helps you act on the whole of it: allocate, rebalance, or trade. That is the set above.

Some of these tools can, and they are the ones that hold your money. Per their own sites in October 2026, Betterment and Wealthfront harvest losses automatically in taxable accounts, Wealthfront adds direct indexing above $100,000, and Schwab Intelligent Portfolios harvests on taxable accounts of $50,000 or more once you opt in. M1 Finance's pricing page does not list it. The self-directed tools mostly flag opportunities rather than trade them: Mezzi surfaces wash-sale risk, and PortfolioPilot's paid plans list tax-saving opportunities. Walnut does not harvest tax losses; what it adds is a keep, trim or exit read on each holding, so you can see which positions lag the S&P 500 before you decide what to sell.

With an IRA, mostly yes. Betterment (traditional, Roth and SEP IRAs, plus 401(k) rollovers), Wealthfront (traditional, Roth and SEP IRAs), Schwab Intelligent Portfolios (traditional, Roth, rollover, inherited, SEP and SIMPLE IRAs) and M1 Finance (traditional, Roth and SEP IRAs, plus rollovers) all manage them. A workplace 401(k) is different: it sits with your employer's plan provider, so a robo can only manage it after you roll it over. Walnut reads IRAs held at a connected brokerage and splits holdings by account; for a 401(k) at a plan administrator you can record the balance yourself, which counts toward totals only.

A handful of well-known tools get searched right alongside portfolio management but really track or analyze rather than rebalance or trade. They inform management decisions without acting on them, so it is worth naming them for what they actually are. For the tracking side specifically, see the dedicated best AI portfolio trackers roundup.

• Kubera. A net-worth tracker that aggregates brokerage, bank, crypto, and real-estate or other assets into a single view. Best for: seeing total net worth, including assets outside the market, in one place. It tracks the whole picture rather than rebalancing any part of it.
• Monarch Money. A budgeting and net-worth app that aggregates your financial accounts, so investments sit next to spending and goals. Best for: keeping an eye on investments inside a household budgeting picture. Its investment view is tracking and allocation, not active rebalancing.
• Morningstar Investor. Morningstar's subscription platform with an X-ray view of allocation, holding overlap, and style, alongside its research and star ratings. Best for: research-grade analysis of a portfolio you hold elsewhere. It analyzes and rates; it does not place trades.
• Sharesight. A performance and dividend tracker with strong tax reporting that measures returns including dividends across accounts. Best for: performance and dividend tracking with tax reporting. It reports on the portfolio rather than managing it.

We limited the field to tools that actually help you manage a portfolio, which is why pure analyzers and stock-scorers sit in their own sections. Within that set we weighed six things specific to management:

• What it actually does: whether it rebalances, automates, places trades, or only recommends changes you execute yourself.
• Control model: whether it holds your money and runs it, or sits on the broker you already have and keeps you in control.
• Rebalancing mechanics, and whether changes are automatic, rules-based, or approved by you.
• Transparency: whether the management logic shows its reasoning or hands you a verdict to trust blindly.
• Honesty of the marketing: we marked down anything implying guaranteed market-beating returns, because no management tool can promise that.
• Cost: the price on the provider's own pricing page, turned into dollars on three balances.

What we checked, in October 2026: each provider's own pricing or product page (PortfolioPilot, Portfolio Genius, Ziggma, Fidelity Go, Vanguard Digital Advisor, Wealthfront and the rest), plus Walnut's own feature set. Where a provider's site did not show a current price, we describe the pricing model without a number. Walnut ranks first for the self-directed job; each use-case ranking stands on its own. Figures and features change, so verify on each provider's site before you sign up.

• Barebone AI, Tengu, AInvest and dub. AI answers name them, but we could not confirm current pricing and features on their own sites in October 2026, so we left them out rather than guess.
• getquin. A Europe-focused portfolio tracker (Free; Premium €89.99/yr; Wealth €149.99/yr). It tracks rather than manages.
• Portfolio Visualizer. Backtesting and allocation analysis; it does not connect to your broker to manage or trade.
• Danelfin and Kavout. Stock scorers that rate single tickers, covered in the section on stock-scorers.
• Kubera, Monarch Money, Morningstar Investor and Sharesight. Trackers and research platforms, covered in the adjacent-tools section.

This guide covers software for individual investors. Two other categories share the name. Institutional investment platforms such as BlackRock's Aladdin and Addepar are sold to asset managers and wealth firms. Project portfolio management software such as Planisware and ServiceNow SPM manages a company's projects, not investments. Advisors and firms can start with software for wealth managers. Walnut here means the AI investing app at walnutinvest.com, not the Walnut product-demo platform, Walnut Algorithms, or any budgeting or FP&A software.

The quickest way to narrow it down is to match the tool to how you want to manage.

• You want to define a strategy and let it run. Composer builds, backtests, and automatically rebalances rules-based strategies; SigFig's managed product runs a diversified portfolio for you.
• You want a critique with concrete changes to make yourself. PortfolioPilot connects your accounts and recommends a change list with a risk score; Empower's free Investment Checkup is a lighter alternative.
• You hold several accounts and care about taxes. Mezzi aggregates everything and layers tax-aware insights; Origin adds full planning around it.
• You want to explore and ask questions in plain English. Magnifi is conversational and strong for fund discovery to inform your allocation.
• You want to know what to keep, trim or exit, and act at your own broker. Walnut gives each holding a keep, trim or exit read against the S&P 500, builds baskets toward target weights, and places the trades you approve, through its own app or by asking Claude or ChatGPT.

To be upfront, since this is our site: Walnut is a free AI investing app, and an AI portfolio management tool for self-directed investors, that reads the broker you already have and places the trades you approve. Its dashboard measures each holding's one-year return against the S&P 500, classifies it as outperforming, in line or lagging, and gives a keep, trim or exit read that also weighs momentum and position size. You can turn a thesis into a basket with target weights, see the trades that would bring it back to those weights, set up recurring buys that spend cash already in your account, and approve each trade. Trades go through at Public, E*Trade, tastytrade, Webull, moomoo, Questrade, Wealthsimple, Trading 212 and Stake; at Robinhood, Schwab, Fidelity and Vanguard it is read-only. It has its own AI assistant, and a connector lets Claude and ChatGPT read the same portfolio. Because broker feeds do not pass cost basis, Walnut uses one-year price returns rather than realized profit and loss, and says so. It is free to use (Walnut Unlimited, $9.99 a month on the web, removes the assistant's per-session limit), charges no fee on assets, and never moves money into or out of your account.

Just as importantly, here is when another tool fits the management job better:

• You want fully automated, rules-based management. Composer builds, backtests, and runs strategies on autopilot; Walnut keeps you in the loop with approval on every trade.
• You want someone to run the money for you. SigFig's managed account or a robo-advisor like Betterment or Wealthfront holds and manages assets on your behalf; Walnut leaves you in control of your own broker.
• You want deep tax-lot and tax-loss management across many accounts. Mezzi is built around that tax-aware, multi-account lens; Walnut does not see cost basis and does not harvest losses.
• You want management bundled with full financial planning. Origin spans budgeting, planning, and investing; Walnut stays focused on the portfolio.
• You want a one-shot risk score and recommendation report. PortfolioPilot delivers that structured change list directly; Walnut is more interactive.
• You do not want to connect a brokerage at all. Walnut sits on top of your real account, so it needs one. A tool that takes manual holdings entry would suit better.

From a connected account you can dig into a specific stock, an ETF you hold, or a theme you want exposure to. For the wider field, see the best AI investing apps roundup, the best AI portfolio analyzers, a walkthrough of how to analyze your portfolio with AI, or how to connect your brokerage to an AI assistant.

The category splits on two questions: how hands-off you want to be, and whether you want to keep your own broker. If you want to keep it and stay in charge, Walnut, a free AI investing app, tells you what to keep, trim or exit and places the trades you approve there. For fully automated, rules-based management, Composer leads; for a managed account, Betterment or Wealthfront (0.25%), or Fidelity Go at $0 under $25,000. For a critique with concrete changes to make yourself, PortfolioPilot is strong; for tax-aware decisions across accounts, Mezzi; for management inside a plan, Origin; for a pre-trade check, Ziggma; for plain-English research, Magnifi; for a free allocation dashboard, Empower. Verify pricing and features on each provider's site before you sign up.
