Walnut vs Magnifi: Which Is Better in 2026?

Figures and features are point-in-time and change; treat the table as a starting map, not a live quote.

The AI that knows your portfolio. Ask anything in plain English, research any stock or fund, and get an honest second opinion, on the broker you already use. Read-only by default, you approve every trade, and it never holds your money. Walnut is not an investment adviser.

How it works: You connect the brokerage you already use through a secure, read-only link, so your login stays with your broker and Walnut sees positions rather than credentials. You then analyze and manage that portfolio by talking through Claude or ChatGPT, and you can group holdings into thematic baskets built around a thesis. When you decide to act, Walnut prepares the trades and routes them back to your own broker for you to approve.

In practice, Walnut’s AI conversational + thematic baskets + trade. It falls under chat-driven management of your own brokerage, which makes it best suited to talking to your own brokerage with ai. On connecting an account it is “Yes (your own broker)”, and on execution it is “Read + you approve”. It is priced as free tier.

One honest limitation: It sits on top of your broker rather than being a broker itself, so you connect an existing account.

A conversational AI investing assistant you can ask natural-language questions about funds and holdings, with account-connection features. Best for research and discovery in plain English.

How it works: Magnifi is built around a chat box: you ask plain-English questions like "what are low-cost clean-energy ETFs?" or "how diversified am I?" and it surfaces investments, side-by-side comparisons, and observations. You can link accounts so its answers reflect what you actually hold, and it points you toward funds and stocks to consider.

In practice, Magnifi’s AI conversational fund/stock research. It falls under ai stock research and scoring, which makes it best suited to research and discovery in plain english. On connecting an account it is “Partial”, and on execution it is “Read / discovery”. It is priced as subscription.

One honest limitation: Skews toward fund discovery rather than managing a concentrated stock portfolio.

The honest framing: Magnifi is about generating stock ideas, scores, or signals to research, while Walnut is about acting on the portfolio in your own broker and tracking it as thematic baskets. Magnifi produces research and signals you then act on somewhere else, whereas Walnut connects your real account so the AI works on your actual holdings.

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

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.

• Walnut: reads your real connected holdings. Walnut connects your real brokerage (Yes (your own broker)) and works from your actual positions, so its answers reflect what you genuinely own rather than a generic model.
• Magnifi: partial account connection. Magnifi offers some account-connection features, but it leans toward research and discovery rather than a full, continuous read of your real positions.

This is where they diverge most. One works from your real, connected account while the other does not, so if you want an assistant grounded in the exact positions you already hold, that gap is the thing to weigh first. 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.

There is no universal winner here; the right pick depends on the job you are hiring the tool for. Match the category to your intent rather than chasing a single “best.”

• Choose Walnut if you want talking to your own brokerage with ai. Its AI conversational + thematic baskets + trade, it is priced as free tier, and it fits chat-driven management of your own brokerage. It is built for hands-on investors who want an AI layer on the broker they already have, without moving their money. Keep in mind that it sits on top of your broker rather than being a broker itself, so you connect an existing account.
• Choose Magnifi if you want research and discovery in plain english. Its AI conversational fund/stock research, it is priced as subscription, and it fits ai stock research and scoring. It is built for investors who want to research and discover funds by chatting in plain English. Keep in mind that skews toward fund discovery rather than managing a concentrated stock portfolio.

Because they sit in different categories, this is not strictly either-or: some investors use one for talking to your own brokerage with ai and the other for research and discovery in plain english, and just watch for overlapping costs.

Cost is easy to misread when two tools charge in different shapes, so compare the model, not just the number. Walnut is priced as free tier, while Magnifi is priced as subscription. 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.

Pricing and tiers change often. Confirm the current numbers on each provider’s own site before you decide; the framing above is point-in-time.
