Mezzi vs Range: Which Is Better in 2026?

Prices checked October 2026. A price marked (Oct 2026) was read on the vendor's own pricing page; others are described without a number because we could not verify one.

Aggregates your accounts and layers AI insights with a tax-aware lens. Best for a consolidated view across holdings.

How it works: Mezzi aggregates your investment accounts into one view and layers AI insights over them with a tax-aware lens, flagging things like potential wash sales, fee drag, and unrealized-gain considerations across accounts. It is read-only: it tells you what it sees and what to consider, and you act at your broker.

In practice, Mezzi’s AI aggregates accounts + tax-aware insights. It is an AI investing app that connects the brokerage you already use, best suited to aggregated wealth tracking with AI. On connecting an account: yes. On execution: read. Cost: subscription.

One real limitation: Focused on tracking and insight; it does not build thesis-driven baskets.

A flat-fee wealth management membership aimed at high-earning professionals, with equity compensation and tax planning at the centre.

How it works: You pay a flat annual membership and get advisors plus software covering equity compensation, tax planning, retirement projections and estate coordination, with accounts aggregated for a whole picture. The design assumes a high income and complexity from RSUs or options, even without a large accumulated balance.

In practice, Range’s AI software layer over human advice. It is a robo-advisor (hands-off automated investing), best suited to high earners with equity compensation, on a flat membership. On connecting an account: aggregates accounts for the advice picture. On execution: advisor-managed where applicable. Cost: $3,950 to $12,500/yr flat membership, no AUM fee (Oct 2026).

One real limitation: Aimed at high household income, so the membership is poor value for a simpler situation.

Category comes first. Mezzi focuses on aggregated wealth tracking with AI (aggregates accounts + tax-aware insights), and Range on high earners with equity compensation, on a flat membership (software layer over human advice). On broker connection they differ too: Mezzi is “Yes” versus Range at “Aggregates accounts for the advice picture”. That shapes everything downstream: how personal the answers are, where trades settle, and how much control you keep over individual positions.

Every tool gives something up for what it does well. Below is the give-and-take on each, so you can weigh the specific strengths against the limitations that come with them, beyond the headline category.

For AI investing tools, the distinction that matters most is whether the tool works from your actual, connected positions or reasons from something else: a separate account it manages for you, or the tickers and numbers you feed it. It decides how personal the answers can be, and where your money physically lives.

• Mezzi: reads your real connected holdings. Mezzi connects your real brokerage (Yes) and works from your actual positions, so its answers reflect what you actually own.
• Range: reads your real connected holdings. Range connects your real brokerage (Aggregates accounts for the advice picture) and works from your actual positions, so its answers reflect what you actually own.

On this specific question the two land on the same side, so the deciding factors between them are elsewhere: category, cost, and who each is built for. This holdings-aware angle is the one Walnut is built around: it connects the brokerage you already use and reasons from your live positions, read-only by default, with any trades left for you to approve.

Each one wins a different job, so the answer depends on which job you need done.

• Choose Mezzi if you want aggregated wealth tracking with AI. Its AI aggregates accounts + tax-aware insights, and it costs subscription. It is built for multi-account investors who want tax-aware tracking and insights consolidated in one place. Keep in mind: focused on tracking and insight; it does not build thesis-driven baskets.
• Choose Range if you want high earners with equity compensation, on a flat membership. Its AI software layer over human advice, and it costs $3,950 to $12,500/yr flat membership, no AUM fee (Oct 2026). It is built for a high-earning professional with RSUs or options whose complexity comes from compensation more than from an accumulated portfolio. Keep in mind: aimed at high household income, so the membership is poor value for a simpler situation.
• Choose Walnut if you want a keep, trim or exit read on the stocks you already own, and placing the trades you approve. It is an AI investing app that connects the broker you already use, and it costs free; Walnut Plus $9.99/mo on the web; no fee on assets.

Because they sit in different categories, this is not strictly either-or: some investors use one for aggregated wealth tracking with AI and the other for high earners with equity compensation, on a flat membership, and watch for overlapping costs.

Cost is easy to misread when two tools charge in different shapes, so compare the model, not just the number. Mezzi: subscription. Range: $3,950 to $12,500/yr flat membership, no AUM fee (Oct 2026). A percentage-of-assets fee scales with your balance, a flat subscription does not, and a “free” tier usually earns elsewhere (on cash, order flow, or premium upgrades), so the cheapest headline is not always the cheapest outcome for your situation.

Prices checked October 2026. Pricing and tiers change, so confirm the current numbers on each provider’s own site before you decide.

Walnut is an AI investing app, and it is the pick for a keep, trim or exit read on the stocks you already own, and placing the trades you approve (free; Walnut Plus $9.99/mo on the web; no fee on assets). It connects the brokerage you already use, read-only by default, gives each holding a keep, trim or exit read against the S&P 500, flags any position above a quarter of the portfolio, and places the trades you approve. You use it through its own assistant, or inside Claude or ChatGPT. See Walnut vs Mezzi and Walnut vs Range.
