What is Kavout?
AI Kai Score ratings and quant signals with an institutional lean. Best for data-oriented investors.
How it works: Kavout applies machine learning across fundamentals, technicals, and alternative data to generate the Kai Score, a numerical equity rating, alongside other quant factor signals.

What is Merrill Guided Investing?
Merrill's automated investing service, built on Bank of America research, with an optional tier that adds an advisor.
How it works: A questionnaire sets a goal and risk level, and Merrill invests in model portfolios built by its investment office, rebalancing automatically.

Kavout vs Merrill Guided Investing: how they actually differ
The core difference is category. Kavout focuses on data-oriented quant signals (ai kai score ratings), and Merrill Guided Investing on bank of america customers who want managed portfolios in the same app (automates a research-driven model portfolio). On broker connection they differ too: Kavout is “No” versus Merrill Guided Investing at “No (holds your money at Merrill)”. That shapes everything downstream: how personal the answers are, where trades settle, and how much control you keep over individual positions.
Kavout vs Merrill Guided Investing: strengths and trade-offs
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.
Kavout
Where it is strong
- 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)
What to watch out for
- 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
Merrill Guided Investing
Where it is strong
- Integrated with Bank of America, including reward tiers that cut the fee
- Portfolios come from a large in-house research operation rather than a pure algorithm
- An advisor tier is available without moving firms
What to watch out for
- More expensive than the cheapest automated services unless rewards tiers apply
- Portfolios lean on Merrill's own funds and research, which is a narrower opinion than an open comparison
The key divider: does it read your real holdings?
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.
- Kavout: does not see your holdings. Kavout works from market data and the tickers you research, not your live positions. You read its output, then act in whichever broker you keep your money at.
- Merrill Guided Investing: manages a separate account it holds. Merrill Guided Investing 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 Merrill Guided Investing.
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.
Kavout vs Merrill Guided Investing: which should you choose?
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 Kavout if you want data-oriented quant signals. Its AI ai kai score ratings, it is priced as subscription, and it fits ai stock research and scoring. It is built for data-oriented investors who are comfortable interpreting quant signals themselves. Keep in mind that steeper learning curve, less beginner-friendly.
- Choose Merrill Guided Investing if you want bank of america customers who want managed portfolios in the same app. Its AI automates a research-driven model portfolio, it is priced as percentage of assets, higher with an advisor (verify current), and it fits hands-off automated investing (robo-advisors). It is built for an existing Bank of America customer whose rewards tier makes the pricing competitive and who values everything in one app. Keep in mind that priced above the cheapest automated services, and the portfolios lean on merrill's own research and funds.
Because they sit in different categories, this is not strictly either-or: some investors use one for data-oriented quant signals and the other for bank of america customers who want managed portfolios in the same app, and just watch for overlapping costs.
Kavout vs Merrill Guided Investing: pricing and cost model
Cost is easy to misread when two tools charge in different shapes, so compare the model, not just the number. Kavout is priced as subscription, while Merrill Guided Investing is priced as percentage of assets, higher with an advisor (verify current). 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.
Where Walnut fits
If neither quite fits, Walnut sits in a third category: chat-driven management of your own brokerage. It connects the brokerage you already use through SnapTrade, lets you analyze and manage it by talking through Claude or ChatGPT, build thematic portfolios around a thesis, and place trades you approve. Read-only by default. See Walnut vs Kavout and Walnut vs Merrill Guided Investing. Walnut is not an investment adviser.
