Walnut vs Farther: 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.

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, read-only by default, so your login stays with your broker and your money never moves. Walnut gives each holding a keep, trim or exit read from its one-year price return against the S&P 500, its momentum and its size, and flags any position above a quarter of the portfolio. You ask follow-up questions in Walnut's own assistant, or inside Claude or ChatGPT through its connector, which only reads. You can turn a thesis into a basket with target weights, and when you decide to act Walnut drafts the trades and places the ones you approve at Public plus eight other brokers including E*Trade, tastytrade and Webull.

In practice, Walnut’s AI reads your real holdings, rates each one against the S&P 500, builds baskets and drafts trades. It is an AI investing app that connects the brokerage you already use, best suited to a keep, trim or exit read on the stocks you already own, and placing the trades you approve. On connecting an account: yes (the brokerage you already use, read-only by default). On execution: places the trades you approve at Public and eight other brokers. Cost: free; Walnut Plus $9.99/mo on the web; no fee on assets.

One real limitation: It has no cost basis or tax lots, so it reports one-year price returns and cannot show profit and loss, and it is read-only at Schwab, Fidelity and Vanguard.

A technology-forward wealth management firm pairing human fiduciary advisors with a modern client platform.

How it works: Farther is a registered investment adviser whose pitch is that traditional firms run on poor software. You get a human fiduciary advisor for planning and portfolio management, delivered through a platform designed for the client, covering planning, tax awareness and account aggregation.

In practice, Farther’s AI technology layer supporting human advisors. It is a robo-advisor (hands-off automated investing), best suited to a human advisor with better software than most firms have. On connecting an account: no (advisor-managed accounts). On execution: advisor-managed. Cost: negotiable % of assets, capped at 2.0%/yr (Oct 2026).

One real limitation: It is still a percentage-of-assets relationship, so the technology does not change the fee arithmetic at larger balances.

In short, Farther is about fully automated, hands-off investing where the platform builds and manages a diversified portfolio for you, while Walnut is about keeping your own brokerage, getting a keep, trim or exit read on each holding, and placing only the trades you approve. Farther holds your money and invests it for you, whereas Walnut sits on top of the broker you already use and leaves you in control.

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.

• Walnut: reads your real connected holdings. Walnut connects your real brokerage (Yes (the brokerage you already use, read-only by default)) and works from your actual positions, so its answers reflect what you actually own.
• Farther: manages a separate account it holds. Farther does not read the brokerage you already use. It opens and holds a new account, then invests the money you move into it, so its view is limited to what sits inside Farther.

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.

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

• Choose Walnut if you want a keep, trim or exit read on the stocks you already own, and placing the trades you approve. Its AI reads your real holdings, rates each one against the S&P 500, builds baskets and drafts trades, and it costs free; Walnut Plus $9.99/mo on the web; no fee on assets. It is built for investors who already own stocks at a broker and want an AI investing app to tell them which to keep, trim or exit, without moving their money. Keep in mind: it has no cost basis or tax lots, so it reports one-year price returns and cannot show profit and loss, and it is read-only at Schwab, Fidelity and Vanguard.
• Choose Farther if you want a human advisor with better software than most firms have. Its AI technology layer supporting human advisors, and it costs negotiable % of assets, capped at 2.0%/yr (Oct 2026). It is built for someone who wants a real human advisor and is frustrated by how the established firms actually operate day to day. Keep in mind: it is still a percentage-of-assets relationship, so the technology does not change the fee arithmetic at larger balances.

Because they sit in different categories, this is not strictly either-or: some investors use one for a keep, trim or exit read on the stocks you already own, and placing the trades you approve and the other for a human advisor with better software than most firms have, 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. Walnut: free; Walnut Plus $9.99/mo on the web; no fee on assets. Farther: negotiable % of assets, capped at 2.0%/yr (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.
