Best AI Portfolio Trackers in 2026

The fastest way to pick the right tool is to know which of three jobs you actually want. They get conflated constantly, and the wrong category answers the wrong question.

• A tracker aggregates the accounts you already have and monitors them over time: balances, allocation, performance against a benchmark, dividends, and fees. It answers “where do I stand and what changed?” Kubera, Empower, Sharesight, Snowball Analytics, and Delta are trackers first.
• An analyzer goes deeper on a snapshot: concentration, fund overlap, a risk score, and a benchmark-relative critique of what you hold. It answers “is this mix any good?” PortfolioPilot and Mezzi blend tracking with analysis.
• A manager (a robo-advisor like Betterment or Wealthfront) holds your money and invests it for you. It answers “run this for me,” which is not tracking at all; it replaces the portfolio rather than watching it.

Most modern tools straddle the line. Walnut tracks your connected broker, analyzes each holding against the S&P 500, and can place a trade you approve, so it spans the first two jobs without becoming a manager. The list below leads with the trackers and notes where each one reaches into analysis.

The most common mistake is reaching for a tool that does a related but different job. Two whole categories get miscategorized as “portfolio trackers” and are not:

• Robo-advisors (Betterment, Wealthfront) build and manage a diversified portfolio for you and hold your money. They replace your portfolio rather than monitoring the one you already own. If your goal is to track what you currently hold at your own broker, handing your money to a managed account does not answer the question.
• Stock-pickers and scorers (Danelfin, Kavout) 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 tracking of how your whole portfolio is moving. They do not aggregate your accounts or follow your net worth over time.

A true portfolio tracker starts from your real, connected accounts and follows the whole picture as it changes. That is the set below.

When a tool says it “tracks your portfolio,” these are the specific jobs worth doing. A good tracker covers most of them; a thin one only touches one or two.

• Account aggregation. Pulling every account into one view, so tracking runs across your whole net worth rather than one brokerage in isolation. Empower and Kubera lead here; Kubera reaches alternatives like crypto and real estate, and Delta spans crypto exchanges.
• Balances and allocation over time. Following total value, cash, and the mix across stocks, funds, sectors, and asset classes, and charting how it moves week to week.
• Performance versus a benchmark. Comparing your portfolio, or each holding, against the S&P 500, so you can tell real outperformance from a rising market. Sharesight reports true total return; Walnut tracks each holding against the S&P 500. Without cost basis (many broker feeds do not pass it) this is usually framed as a window return, not realized profit and loss.
• Dividends and income. Tracking dividends received, yield on cost, and forecast income. Snowball Analytics is built around this; Sharesight reports it precisely.
• Fees and tax drift. Surfacing expense ratios eating into returns, and tax inefficiencies like avoidable short-term gains or wash-sale risk. Empower has a fee analyzer; Mezzi leads on tax-aware insights.

Under the hood, most trackers run the same pipeline; the differences are in breadth, accuracy, and what sits on top. Knowing the mechanism makes it obvious why some tools are always current and others go stale.

• 1. Connection. You link your accounts once, usually through a regulated aggregator like a regulated aggregator, so your login stays at your broker and the tracker gets read-only access. Kubera, Empower, Mezzi, and Walnut work this way. Tools like Sharesight, Snowball Analytics, and Delta may sync from some brokers and rely on manual or file-based entry for the rest.
• 2. Aggregation and normalization. The tracker pulls positions, cash, and transactions from every linked account and maps them to a common set of securities, so a share of the same fund held in two accounts rolls up into one line.
• 3. Valuation and performance math. Live or delayed prices value each holding, then the tool computes return. Where cost basis is available it can report true total return (time-weighted or money-weighted); where a broker feed does not pass cost basis, it falls back to a window return (how a holding moved over a chosen period). This is why Sharesight can produce audited-grade numbers while chat-first tools often frame results as window returns.
• 4. Benchmarking and enrichment. The normalized holdings are compared against an index like the S&P 500, and enriched with dividends, sector and geography breakdowns, fees, and (in the AI tools) a natural-language layer that lets you ask what changed.
• 5. Ongoing refresh. A connected tracker re-syncs on a schedule, so the picture stays current without you re-keying anything. A manual tracker is only as fresh as your last update.

The AI part is mostly in step four: turning the aggregated, benchmarked picture into plain-language answers. Walnut is the AI investing assistant that talks to the broker you already have and places the trades you approve, so the same connection that powers tracking can also act, with your sign-off, at your own broker.

• Whether it connects your real accounts read-only, or makes you re-key holdings by hand. Live connection is the difference between an always-current tracker and a stale spreadsheet.
• Breadth of what it can track: stocks only, or stocks plus crypto, real estate, and private assets. Kubera and Delta reach furthest; Sharesight and Snowball focus on securities.
• How performance is computed: ask whether numbers are time-weighted, money-weighted, or a simple window return, and whether cost basis is included. Sharesight is precise here; chat tools without cost basis use window returns.
• Benchmark comparison, not just a balance. A tracker that shows you versus the S&P 500 tells you far more than one that only shows a rising line.
• Whether tracking comes with insight, like a risk read (PortfolioPilot) or a tax-aware lens (Mezzi), or whether it stops at balances.
• Cost model: a free tier, a flat subscription, or a percentage of assets. A percentage-of-assets fee is a managed-advisory model, not a tracker, and is usually the wrong one for monitoring.
• How it handles your data and credentials. The safer tools never store your broker login and default to read-only access through a secure aggregator.

Each tool below is described on the same six fields, so you can scan across them: what it is, what the AI or automation does, whether it connects your accounts, the pricing model, who it suits, and one honest limitation.

There is no overall number one, because the right tracker depends on what you are trying to watch. Below the field is ranked inside each use-case, with the stronger fit first. Walnut leads only in its own category (chat-driven tracking of your own broker), not across the board.

We limited the field to tools that actually track a portfolio you already hold, which is why robo-advisors and stock-scorers are not on the list. Within that set we weighed five things specific to tracking:

• Connection model: whether it reads your live accounts or relies on manual entry, and whether the link is read-only by default.
• Breadth: how many account and asset types it tracks, from a single brokerage up to crypto, real estate, and private holdings.
• How performance is measured, and whether the tool is honest about the limits (for example, window returns when cost basis is unavailable) and benchmarks against an index.
• Depth of insight on top of tracking: whether it stops at balances or adds dividends, fees, a tax lens, or a risk read.
• Honesty of the marketing: we marked down anything implying guaranteed market-beating returns, because no tracker can promise that.

We did not crown a single overall winner. The best tracker depends on what you want monitored and how broad your wealth is. Figures and features change; treat the specifics here as a starting point and verify on each provider's site.

The quickest way to narrow it down is to match the tracker to what you want to watch.

• Your wealth spans crypto, real estate, and private assets. Kubera aggregates alternatives alongside brokerage accounts into one net-worth tracker; Delta is a lighter mobile option for stocks plus crypto.
• You want a free net-worth and allocation tracker. Empower's free dashboard aggregates accounts and tracks allocation and fees; Delta's free tier covers stocks and crypto on mobile.
• You want accurate total-return and dividend numbers. Sharesight reports true total return with benchmarking and tax reports; Snowball Analytics leans into dividend income tracking and forecasts.
• You want tracking with a tax-aware or second-opinion layer. Mezzi tracks aggregated accounts with a tax lens; PortfolioPilot tracks linked accounts and adds a risk-scored critique.
• You want to track your real broker by chatting with an AI. Walnut connects your account and lets you monitor it through Claude or ChatGPT, with each holding tracked against the S&P 500 and any trade you approve.

To be upfront, since this is our site: Walnut is a portfolio tracker of the chat-driven kind, and it leads in that category rather than overall. It connects your existing brokerage and lets you monitor what you hold by talking through Claude, ChatGPT, or a built-in assistant. It analyzes drift, concentration, and drawdown on your real holdings, and its dashboard tracks each holding's return against the S&P 500 and classifies it as outperforming, in line, or lagging, alongside momentum reads, and you can group holdings into thematic portfolios to track over time. Because broker feeds rarely pass cost basis, Walnut tracks results as a window return rather than realized profit and loss, and says so. It is read-only by default, every trade needs your approval, and you keep the broker you already use. Walnut is not an investment adviser.

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

• You want to track crypto, real estate, and private assets in one net-worth view. Kubera is built for that breadth; Walnut focuses on your connected brokerage.
• You want audited-grade total-return and tax reporting. Sharesight is purpose-built for accurate performance, dividends, and tax reports; Walnut tracks returns against the S&P 500 but is not a tax-reporting tool.
• You are a dividend-income investor who wants forecast income. Snowball Analytics centers on dividend tracking and forecasting; Walnut does not specialize in income.
• You want deep tax-lot and tax-loss tracking across many accounts. Mezzi is built around that tax-aware, multi-account lens; Walnut's focus is conversational tracking and thematic portfolios.
• 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.
• You want managed money rather than tracking. If you would rather hand your portfolio to be run for you, a robo-advisor is the right category, not a tracker.

From a connected account you can dig into a specific stock, an ETF you hold, or a theme you want exposure to. Once you can see what you hold, the natural next steps are to critique it and act on it.

A common thing tracking surfaces is over-exposure, so it is worth learning how to check portfolio concentration.
