Best Free AI Portfolio Analyzers in 2026
Last updated October 2026
Short answer
The best free AI portfolio analyzer is Walnut, an AI investing app that connects the brokerage you already own read-only and gives each holding a keep, trim or exit read against the S&P 500 at no cost. Empower is best for a free allocation-and-fee checkup across linked accounts, and PortfolioPilot for a free risk-scored assessment. Portfolio Visualizer adds free backtesting depth, SigFig free tracking with an analysis digest, and ChatGPT free reasoning over whatever you paste in or, in the US, link through Finances. Walnut is not an investment adviser.
Walnut is the AI portfolio analyzer that reads the holdings in your existing brokerage account and answers questions about them in plain English, without taking custody of your money. The free tier covers connecting a broker and tracking your holdings, which is the part most free portfolio analysis solutions charge for or cap.
Free portfolio analysis splits into two questions: what does the free layer actually include, and what is the business model behind it. Both matter, because the second predicts how the product will treat you. This guide ranks six genuinely useful free options with Walnut first, states plainly what each free tier covers and what pitch follows, and names the limit of each one, Walnut included.
The free analyzers, in depth
Walnut
An AI investing app that analyzes the brokerage you already own for free. Connect read-only and it gives each holding a keep, trim or exit read from its one-year return against the S&P 500, momentum and position size, flags anything above a quarter of the portfolio, and answers plain-English questions about concentration and what changed this month. Ask in its own assistant, or inside Claude and ChatGPT through its connector.
- What is free: Connecting a broker, the per-holding reads and the assistant (up to a per-session allowance) are free; Walnut Unlimited is $9.99 a month on the web.
- The catch: Broker feeds rarely pass cost basis, so returns are one-year price returns rather than realized profit and loss, and it does not look inside ETFs.
Empower
The best-known free dashboard: link accounts and the Investment Checkup analyzes allocation against target, flags fee drag, and tracks net worth over time.
- What is free: The full dashboard and checkup are free.
- The catch: The analytics stay at the allocation level, and the business model is an upsell to paid human advisory, so expect outreach.
PortfolioPilot
An AI assessment across linked accounts: risk score, diversification read, and fee findings, with directive depth behind the paid tier.
- What is free: A meaningful free assessment with a risk score.
- The catch: The ongoing, deeper recommendations sit behind the subscription; free is closer to a strong snapshot.
Portfolio Visualizer
Free quant tooling: backtest an allocation you enter, run factor regressions, and check correlations, at a depth consumer apps do not match.
- What is free: Core backtesting and analysis are free.
- The catch: Manual entry, no account connection, and an interface that assumes quant comfort. Deeper features are paid.
SigFig
A free portfolio tracker that links accounts and reports allocation, fees, and performance in a clean weekly digest.
- What is free: Tracking and the analysis digest are free.
- The catch: It is a tracker with analysis rather than an AI analyst: findings are canned, and the upsell is managed investing.
ChatGPT
The general free option: paste your positions in, or in the US link accounts through its Finances feature, and ask for analysis. The reasoning is real; outside the US the data layer is the weakness.
- What is free: Free tier covers the conversation.
- The catch: Outside the US, or without linking accounts through Finances, everything depends on what you paste. Even linked, it reads rather than acts (no trades, no target weights), and stale or wrong numbers can arrive with confidence.

A free stack that covers the whole job
Because each free tier covers a different slice, the strongest free setup is a small stack rather than one tool:
- Monitoring: Empower or SigFig watching allocation and fees in the background.
- Understanding: Walnut connected to the same brokerage for on-demand questions about concentration, overlap, and what dragged the month; see how to analyze your portfolio with AI.
- A periodic second opinion: PortfolioPilot's free assessment quarterly.
- Hypotheticals: Portfolio Visualizer when you want to backtest a change before making it.
All four connect read-only or take manual input, so the stack costs nothing and moves no money. The paid field, when a free finding needs depth, is ranked in the best AI portfolio analyzers roundup.
The bottom line
Free covers more of portfolio analysis than most people expect: Walnut for a per-holding read of your real account, Empower for the standing checkup, PortfolioPilot for the risk-scored snapshot, Portfolio Visualizer for the quant depth. Know the business model behind each free tier, connect read-only always, and pay only when a specific unresolved question justifies it.

FAQ
What is the best free AI portfolio analyzer?
Walnut is the best free AI portfolio analyzer for the brokerage you already own: it connects read-only and gives each holding a keep, trim or exit read against the S&P 500, free. Best for a free allocation-and-fee checkup: Empower. Best for a free risk score: PortfolioPilot. Best for free backtesting: Portfolio Visualizer. Best for a free tracking digest: SigFig. Best for reasoning over positions you paste in: ChatGPT. Walnut is not an investment adviser.
Is there a completely free way to analyze my portfolio with AI?
Yes, several genuinely free paths: Empower's checkup, Walnut's free tier for connected chat analysis, PortfolioPilot's free assessment, and Portfolio Visualizer's core tools. 'Free' has different business models behind it: advisory upsells (Empower, SigFig), paid depth tiers (PortfolioPilot, Portfolio Visualizer), and free product layers (Walnut). None of that makes the free layer less useful; it tells you what pitch to expect later.
What does a free portfolio analysis actually include?
Typically: allocation by asset class and sector, fee drag, a diversification or risk read, and basic performance. What free tiers usually withhold: ongoing monitoring, directive recommendations, tax-aware findings, and depth per holding. The free layers here are honest versions of the real product; be more careful with tools whose free analysis is mainly a lead form for advisory sales.
How good is Walnut's free tier for portfolio analysis?
The free tier covers the core loop: connect a brokerage read-only, get a keep, trim or exit read on each holding against the S&P 500, and ask the assistant about your actual holdings in plain English: concentration, per-position returns, what changed and why. The assistant is free up to a per-session allowance; Walnut Unlimited removes that limit for $9.99 a month on the web. It works in Walnut's own assistant or inside Claude and ChatGPT.
Can I just use ChatGPT for free portfolio analysis?
You can, by pasting positions in or, in the US, by linking accounts through ChatGPT Finances, which reads holdings but cannot trade. For one-off reasoning it is genuinely useful. The costs of the paste route are practical: no live data, no memory of your account, numbers that can be stale or wrong, and re-pasting every time something changes. The free fix for exactly those gaps is a connected analyzer: Walnut's free tier grounds the same conversational analysis in your real account so nothing needs pasting.
Are free portfolio analyzers safe to connect to my brokerage?
The reputable ones connect through regulated aggregators, so your broker login stays with your broker and access is read-only. That applies to Empower, SigFig, PortfolioPilot, and Walnut (read-only by default). The checks that matter: can the tool move money (it should not), what data does it store, and how does it make money. A free tool with no visible business model deserves more scrutiny, not less.
When is a paid portfolio analyzer worth it?
When a free finding needs ongoing depth: continuous monitoring with alerts, tax-aware suggestions across accounts, factor-level analysis, or accurate multi-currency total returns. Those are the genuine paid tiers of PortfolioPilot, Mezzi, Portfolio Visualizer, and Sharesight. If your free analyzer keeps surfacing the same unresolved question, that question is usually the thing worth paying to answer.
What is the difference between a free tracker and a free analyzer?
A tracker (SigFig, most broker apps) records balances and returns. An analyzer explains: why the portfolio behaves as it does, where the risk concentrates, what is dragging performance. Empower and PortfolioPilot analyze at the allocation level; Walnut analyzes conversationally at whatever level you ask about. If you already know what your portfolio holds and want to know what it means, you want the analyzer side.
