What is Danelfin?

Assigns each stock an AI Score estimating its probability of beating the market over the coming months. Best for research-driven stock pickers who want a quantitative signal.

How it works: Danelfin's models crunch thousands of fundamental, technical, and sentiment features per stock every day and distill them into a single AI Score from 1 to 10, meant to reflect the probability of beating the market over the next few months. You browse the scores, filter for high-rated names, and then buy them in whatever broker you already use.

In practice, Danelfin’s AI scores stocks (AI Score 1-10). It is an AI stock research and scoring tool, best suited to quantitative stock signals. On connecting an account: no (research only; you buy at your own broker). On execution: none. Cost: subscription.

One real limitation: It scores stocks; it does not hold your money, manage a portfolio, or read the account you already have.

What is Marcus Invest?

Goldman Sachs' former automated investing service, closed in 2024 when its accounts moved to Betterment.

How it works: Marcus Invest used a questionnaire to set a risk level and invested in model ETF portfolios built by Goldman Sachs. Goldman Sachs closed it in 2024 and transferred the accounts to Betterment, so anyone who held one now has a Betterment account under Betterment's own pricing.

In practice, Marcus Invest’s AI discontinued in 2024. It is a robo-advisor (hands-off automated investing), best suited to former Marcus Invest clients checking where their account went. On connecting an account: no (holds your money at Marcus). On execution: not offered. Cost: discontinued; accounts moved to Betterment (2024).

One real limitation: Marcus Invest is closed: Goldman Sachs moved its accounts to Betterment in 2024, so the comparison that matters now is Betterment itself.

Danelfin vs Marcus Invest: how they actually differ

Category comes first. Danelfin focuses on quantitative stock signals (scores stocks (AI Score 1-10)), and Marcus Invest on former Marcus Invest clients checking where their account went (discontinued in 2024). On broker connection they differ too: Danelfin is “No (research only; you buy at your own broker)” versus Marcus Invest at “No (holds your money at Marcus)”. That shapes everything downstream: how personal the answers are, where trades settle, and how much control you keep over individual positions.

Danelfin vs Marcus Invest: strengths and trade-offs

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.

Danelfin

Where it is strong

  • A single, transparent AI Score with a published, backtested track record
  • Scores ETFs as well as individual stocks
  • Breaks down the low- and high-scoring drivers behind each rating

What to watch out for

  • It is a signal service, not a portfolio manager: it will not hold, rebalance, or trade for you
  • Scores are probabilistic and can be wrong on any given name

Marcus Invest

Where it is strong

  • Accounts moved to Betterment and were not closed out, so former clients did not have to sell

What to watch out for

  • The service no longer exists, so any review describing current Marcus Invest pricing or features is out of date
  • Former clients are now on Betterment's terms, not Marcus's

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.

  • Danelfin: does not see your holdings. Danelfin 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.
  • Marcus Invest: manages a separate account it holds. Marcus Invest 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 Marcus Invest.

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.

Danelfin vs Marcus Invest: which should you choose?

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

  • Choose Danelfin if you want quantitative stock signals. Its AI scores stocks (AI Score 1-10), and it costs subscription. It is built for research-driven stock pickers who want a quantitative second opinion before they buy. Keep in mind: it scores stocks; it does not hold your money, manage a portfolio, or read the account you already have.
  • Choose Marcus Invest if you want former Marcus Invest clients checking where their account went. Its AI discontinued in 2024, and it costs discontinued; accounts moved to Betterment (2024). It is built for nobody opening a new account, since the service is closed; former clients should compare Betterment, where their account now sits. Keep in mind: marcus Invest is closed: Goldman Sachs moved its accounts to Betterment in 2024, so the comparison that matters now is Betterment itself.
  • 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 quantitative stock signals and the other for former Marcus Invest clients checking where their account went, and watch for overlapping costs.

Danelfin vs Marcus Invest: pricing and cost model

Cost is easy to misread when two tools charge in different shapes, so compare the model, not just the number. Danelfin: subscription. Marcus Invest: discontinued; accounts moved to Betterment (2024). 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.
