Mezzi Review: Tooliverse Consensus
Based on 265 verified reviews across 4 platforms,
combined with Tooliverse's expert analysis
Mezzi functions as an X-ray machine for self-directed investors, revealing hidden concentrations and tax inefficiencies across multiple brokerages and account types. The institutional-grade analysis and proactive tax-loss harvesting deliver insights previously available only through expensive percentage-based advisors, at a flat annual fee that makes economic sense for portfolios above $250,000. Cost basis accuracy issues can undermine tax recommendations, and insights plateau after initial setup, but ongoing monitoring catches opportunities that individual brokerage dashboards structurally cannot see.
Bottom line: A top-tier portfolio analysis platform that reveals what you actually own across all accounts and finds tax savings traditional advisors would charge thousands for, though cost basis quirks require verification before acting on tax suggestions.

Mezzi Features 2026
Exposure X-Ray
Institutional-grade portfolio analysis that reveals every underlying stock holding across all your accounts—401(k)s, IRAs, taxable brokerages. See hidden concentrations like owning Apple through six different ETFs or having 21% of your wealth in a single stock without knowing. Updates automatically as markets move and funds rebalance.
Tax Optimization
Daily monitoring for tax-loss harvesting opportunities, asset location optimization, and capital gains timing. Alerts you when positions cross short-term to long-term thresholds and identifies misplaced assets (like bonds in Roth IRAs that should be in taxable accounts). Catches tax savings before market recovery closes the window.
Cross-Account Overlap Detection
Identifies when different funds hold the same stocks—like VOO and VTI sharing 500 stocks, or QQQ's holdings already being in VOO. Reveals that your 'different' funds actually hold the same 80 stocks, turning intended diversification into hidden concentration.
Multi-Account Aggregation
Connects all investment accounts in one view—401(k)s, 403(b)s, 457 plans, traditional and Roth IRAs, taxable brokerages, HSAs, 529s, and trusts. Provides unified portfolio analysis that individual brokerages cannot offer since they only see their own slice of your wealth.

More from the Community
"The advanced features like X-rays to find hidden holdings and expense ratio comparisons have been helping me gain more understanding of my portfolio."

Mezzi Pricing 2026
View SourceCore at $25 monthly billed annually is the entry point most self-directed investors need: full Exposure X-Ray analysis, tax optimization alerts, and unlimited AI chat for you and a family member. Plus at $42 monthly adds the deep-thinking AI models and unlimited custom alerts that matter most for complex scenarios like concentrated stock positions or multi-account tax planning. White Glove at $125 monthly makes sense primarily for couples managing household wealth who value hands-on setup and ongoing concierge support over DIY configuration.
Mezzi In-Depth Review 2026
The SEC-registered investment advisor connects every account type—401(k)s, IRAs, taxable brokerages, HSAs, trusts—and runs institutional-grade analysis on your complete financial picture. It works across all major brokerages via read-only connections through Plaid and similar aggregators, meaning it can see your data but can't move money or execute trades. The pricing starts at $299 annually, a flat fee that sidesteps the percentage-of-assets model that makes traditional advisors prohibitively expensive once your portfolio crosses six figures.
What It's Like Day-to-Day
The Exposure X-Ray feature is where the platform earns its keep. Connect your accounts once, and it breaks down every stock holding across every fund in every account, updated daily as markets move and funds rebalance. You discover that your "diversified" portfolio has 12.3% in Apple, 9.7% in Microsoft, and 21% in mega-cap tech overall—concentrations that would horrify a fiduciary advisor but that your individual brokerages literally cannot see because they only know about their slice of your wealth.

Mezzi: Frequently Asked Questions (FAQs)
How is Exposure X-Ray different from my brokerage's portfolio view?
Your brokerage shows only what you hold with them. Exposure X-Ray shows what you own across all accounts. For example, Fidelity shows 'You own VOO, diversified,' but you also own VTI at Vanguard and QQQ at Schwab, creating heavy concentration in mega-cap tech. Fidelity can't see your other accounts—Exposure X-Ray can.
Does Exposure X-Ray work with 401(k)s and IRAs?
Yes. Mezzi connects any account type: traditional and Roth IRAs, 401(k), 403(b), 457 plans, taxable brokerages, HSAs, 529s, and trusts. Exposure X-Ray analyzes all types together.
Will Exposure X-Ray show if I own the same stocks in different funds?
Yes, that's exactly what it's built for. If you own VOO, VGT, and QQQ, Exposure X-Ray shows Apple in all 3 (7.1%, 18.4%, 11.2% of each), Microsoft in all 3 (6.9%, 16.7%, 9.8%), and your total Apple exposure (e.g., 12.3% of your portfolio). Every stock, every fund, every account.
How often does Exposure X-Ray update?
Mezzi provides real-time prices with daily portfolio updates. It updates as you trade, funds rebalance, and markets move—always current.
