Magnifi vs SoFi: 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.

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 is an AI stock research and scoring tool, best suited to research and discovery in plain English. On connecting an account: partial. On execution: read / discovery. Cost: free plan; Premium is a paid subscription (as of October 2026).

One honest limitation: Skews toward fund discovery rather than managing a concentrated stock portfolio.

Automated investing plus an AI financial coach inside an all-in-one money app. Best for beginners already in the SoFi ecosystem.

How it works: Inside the SoFi app you can opt into automated investing, where SoFi allocates a diversified ETF portfolio matched to your risk level and rebalances it, or you can self-direct trades in stocks and ETFs. All of it sits next to SoFi's banking, loans, and credit products, with AI-driven help answering money questions.

In practice, SoFi’s AI automated investing + AI coach. It is a robo-advisor (hands-off automated investing), best suited to beginners in one money app. On connecting an account: no (holds your money). On execution: automated. Cost: 0.25% of account value a year (as of October 2026).

One honest limitation: Lighter on deep research and customization.

The core difference is category. Magnifi focuses on research and discovery in plain English (conversational fund/stock research), and SoFi on beginners in one money app (automated investing + AI coach). On broker connection they differ too: Magnifi is “Partial” versus SoFi at “No (holds your money)”. 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.

• 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.
• SoFi: manages a separate account it holds. SoFi 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 SoFi.

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 is committed per job rather than overall.

• Choose Magnifi if you want research and discovery in plain English. Its AI conversational fund/stock research, and it costs free plan; Premium is a paid subscription (as of October 2026). It is built for investors who want to research and discover funds by chatting in plain English. Keep in mind: skews toward fund discovery rather than managing a concentrated stock portfolio.
• Choose SoFi if you want beginners in one money app. Its AI automated investing + AI coach, and it costs 0.25% of account value a year (as of October 2026). It is built for beginners who want investing bundled with banking in a single, simple app. Keep in mind: lighter on deep research and customization.
• 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 Unlimited $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 research and discovery in plain English and the other for beginners in one money app, 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. Magnifi: free plan; Premium is a paid subscription (as of October 2026). SoFi: 0.25% of account value a year (as of October 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.

Prices checked October 2026. Pricing and tiers change, so confirm the current numbers on each provider’s own site before you decide.

Walnut is an AI investing app, and it is the pick for a keep, trim or exit read on the stocks you already own, and placing the trades you approve (free; Walnut Unlimited $9.99/mo on the web; no fee on assets). It connects the brokerage you already use, read-only by default, gives each holding a keep, trim or exit read against the S&P 500, flags any position above a quarter of the portfolio, and places the trades you approve. You use it through its own assistant, or inside Claude or ChatGPT. See Walnut vs Magnifi and Walnut vs SoFi.
