E*Trade Core Portfolios 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.

E*Trade's automated investing service, offering managed ETF portfolios alongside its self-directed brokerage, now under Morgan Stanley.

How it works: A questionnaire sets a risk level and E*Trade invests in a diversified ETF portfolio with automatic rebalancing, including socially responsible and smart-beta variants. It sits alongside E*Trade's self-directed brokerage, so a managed portfolio and an account you trade yourself live under one login.

In practice, E*Trade Core Portfolios’s AI automates a diversified etf portfolio. It falls under hands-off automated investing (robo-advisors), which makes it best suited to e*trade customers wanting a managed portfolio alongside self-directed trading. On connecting an account it is “No (holds your money at E*Trade)”, and on execution it is “Automated”. It is priced as percentage of assets (verify current).

One honest limitation: A conventional service whose main advantage is sitting next to an E*Trade brokerage 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 core difference is category. E*Trade Core Portfolios focuses on e*trade customers wanting a managed portfolio alongside self-directed trading (automates a diversified etf portfolio), and Magnifi on research and discovery in plain english (conversational fund/stock research). On broker connection they differ too: E*Trade Core Portfolios is “No (holds your money at E*Trade)” versus Magnifi at “Partial”. That shapes everything downstream: how personal the answers are, where trades settle, and how much control you keep over individual positions.

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.

• E*Trade Core Portfolios: manages a separate account it holds. E*Trade Core Portfolios 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 E*Trade Core Portfolios.
• 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 E*Trade Core Portfolios if you want e*trade customers wanting a managed portfolio alongside self-directed trading. Its AI automates a diversified etf portfolio, it is priced as percentage of assets (verify current), and it fits hands-off automated investing (robo-advisors). It is built for an existing E*Trade customer who wants part of the money handled automatically and part self-directed. Keep in mind that a conventional service whose main advantage is sitting next to an e*trade brokerage 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 e*trade customers wanting a managed portfolio alongside self-directed trading 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. E*Trade Core Portfolios is priced as percentage of assets (verify current), 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.

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 E*Trade Core Portfolios and Walnut vs Magnifi. Walnut is not an investment adviser.
