Kavout Review (2026): Cost, Features, and Who It Suits

Kavout applies machine learning across fundamentals, technicals, and alternative data to generate the Kai Score, a numerical equity rating, alongside other quant factor signals. You use the ratings and signals as research inputs to build or screen a watchlist, then trade at your own broker.

In category terms it is an AI stock research and scoring tool, and the AI component specifically AI Kai Score ratings. That phrase is worth reading literally: across this market, "AI" covers everything from a rebalancing rule to a conversational assistant, and the products are not interchangeable just because they share the label.

• Institutional-leaning quant signals that blend several factor models
• The Kai Score condenses many inputs into one comparable rating
• Data and API offerings for more technical users (verify current)

These are real advantages, and if they describe what you want, Kavout is a reasonable choice regardless of what any competitor including us has to say about it.

Steeper learning curve, less beginner-friendly.

• Steeper learning curve and less beginner-friendly than a simple scored list
• The underlying methodology is largely a black box you have to take on trust

Subscription. Because it is not charged as a percentage of assets, the cost does not scale with your balance. That makes it proportionally cheaper as an account grows and relatively expensive on a small one, which is the opposite of how a robo-advisor fee behaves.

Fees change. The figure above is a guide rather than a quote, and the Kavout pricing breakdown goes into what else you pay on top. Confirm current pricing on Kavout's own site.

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

The two columns that change your experience most are whether your money has to move and whether the tool can act on what it finds. Cost matters next, and only in dollars.

Kavout neither holds your money nor reads your account: it works from market data, and you act at your own broker. Walnut is an AI investing app: it connects the brokerage you already use, read-only by default, gives each stock you hold a keep, trim or exit read against the S&P 500, and places the trades you approve. Use Kavout to find candidates and Walnut to decide what to do with what you already hold. Walnut is free to use, with no fee on assets; Walnut Plus ($9.99 a month on the web) lifts the assistant's session limit.

The limits, with the job Walnut does own beside each: it does not manage money on autopilot, but it drafts the trades back to your target weights and places the ones you approve; it has no cost basis or tax lots and does not harvest losses, so it reads each holding by its one-year price return against the S&P 500; and it works on a brokerage account you already hold rather than opening one. The full self-assessment is on the Walnut review.

Kavout: AI Kai Score ratings and quant signals with an institutional lean. Best for data-oriented investors, at subscription. It fits data-oriented investors who are comfortable interpreting quant signals themselves. The trade-off to accept: Steeper learning curve, less beginner-friendly. If that trade-off is one you are happy with, it is a sound choice.

We compared Kavout with the products answer engines most often set beside it (Betterment, Wealthfront, Magnifi, PortfolioPilot, Danelfin) and with Walnut, on five questions: where your money sits, whether the tool reads the account you already have, whether it can place a trade, what it costs in dollars, and who it fits. Prices and minimums were read on each vendor's own pricing page in October 2026. Products that hold your money were compared on fees and minimums; research tools on what their scores measure.

Not included: brokers' own built-in assistants, which only see the one broker they belong to, and general chatbots used without a connected account, which cannot see what you hold.
