SigFig vs Wealthsimple: 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.

An automated investing service that manages accounts held at your existing broker, so you do not move money.

How it works: There is no new account to open: you link an existing brokerage account at a supported custodian and SigFig manages it in place, rebalancing and running tax-efficient strategies. Below a stated balance the management is free. This structure is unusual: nearly every competitor requires custody of your assets.

In practice, SigFig’s AI automates a portfolio in accounts you already hold. It is a robo-advisor (hands-off automated investing), best suited to automation that manages your existing Schwab or Fidelity account. On connecting an account: yes, it manages accounts held at supported brokers. On execution: automated. Cost: up to 0.50%/yr, $2,000 minimum (Oct 2026).

One real limitation: Supported custodians are limited, so it only works if your account is already at one of them.

Canada's largest independent automated investing service, combining managed portfolios with commission-free self-directed trading and banking features.

How it works: A questionnaire sets a managed portfolio of low-cost ETFs, rebalanced automatically, with the management fee tiered down as balances rise. Alongside it, Wealthsimple offers self-directed trading, cash accounts and tax filing, which makes it closer to a full financial app than a pure robo-advisor.

In practice, Wealthsimple’s AI automates a diversified portfolio. It is a robo-advisor (hands-off automated investing), best suited to canadian investors wanting automation and self-directed trading in one place. On connecting an account: no (holds your money at Wealthsimple). On execution: automated, plus self-directed trading. Cost: 0.5%/yr under C$100,000, 0.4% from C$100,000 (Oct 2026).

One real limitation: It is a Canadian service, so it is not an option for US investors.

Category comes first. SigFig focuses on automation that manages your existing Schwab or Fidelity account (automates a portfolio in accounts you already hold), and Wealthsimple on canadian investors wanting automation and self-directed trading in one place (automates a diversified portfolio). On broker connection they differ too: SigFig is “Yes, it manages accounts held at supported brokers” versus Wealthsimple at “No (holds your money at Wealthsimple)”. 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. 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.

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.

• SigFig: connects specific supported accounts. SigFig connects a defined set of accounts (Yes, it manages accounts held at supported brokers), so whether it can see your holdings depends on whether your money is at one of them.
• Wealthsimple: manages a separate account it holds. Wealthsimple 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 Wealthsimple.

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 depends on which job you need done.

• Choose SigFig if you want automation that manages your existing Schwab or Fidelity account. Its AI automates a portfolio in accounts you already hold, and it costs up to 0.50%/yr, $2,000 minimum (Oct 2026). It is built for someone with an existing account at a supported broker who wants it managed without moving anything. Keep in mind: supported custodians are limited, so it only works if your account is already at one of them.
• Choose Wealthsimple if you want canadian investors wanting automation and self-directed trading in one place. Its AI automates a diversified portfolio, and it costs 0.5%/yr under C$100,000, 0.4% from C$100,000 (Oct 2026). It is built for a Canadian investor who wants one app for a managed portfolio, self-directed trades and cash. Keep in mind: it is a Canadian service, so it is not an option for US investors.
• 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 both sit in the same category, the choice comes down to the finer details above. Their basic approach is the same.

Cost is easy to misread when two tools charge in different shapes, so compare the model, not just the number. SigFig: up to 0.50%/yr, $2,000 minimum (Oct 2026). Wealthsimple: 0.5%/yr under C$100,000, 0.4% from C$100,000 (Oct 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 Plus $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 SigFig and Walnut vs Wealthsimple.
