eToro Tori vs Acubic: Native AI or Third-Party?

eToro users searching for AI tools to improve how they manage their portfolio will encounter two very different things: Tori, the AI assistant eToro has built directly into its platform, and Acubic, a third-party portfolio builder that connects to eToro through an approved API connection. Both are described using the word AI. Neither does the same job.

The question of which one to use depends on what you are actually trying to do. If you want to understand what has already happened to your portfolio, Tori is built for that. If you want to build a risk-defined portfolio from a published quantitative method and keep it rebalanced over time, Acubic is built for that. They address different moments in the same investor journey, and the choice between them is not necessarily a choice at all.

What is eToro Tori?

Tori is eToro's AI-powered assistant, built into the eToro platform and available to account holders. It is a conversational tool: it responds to questions about markets and your holdings, explains what has happened to a position or a portfolio, and surfaces relevant information while you navigate the app.

Because Tori is native to eToro, it has direct access to your live positions, your portfolio history, and eToro's own market data. You can ask it why a particular asset moved, how a holding is affecting your overall exposure, or what a market event means for your portfolio, and it answers in context without you leaving the platform.

eToro describes Tori as an AI assistant for investors. The scope of the tool is explanatory: it tells you what your portfolio has done and helps you understand the context around it. It does not build a target allocation, apply a risk model, calculate drift from a constructed benchmark, or propose the specific trades that would bring a portfolio back to a quantitatively-derived target. That is not a limitation specific to Tori; it is simply a different product category. Tori is an assistant. Acubic is an optimiser.

What is Acubic?

Acubic is a third-party portfolio builder. It connects to your eToro account through an OAuth connection, constructs a portfolio using a quantitative method that is published and readable on the Acubic methodology page, and then monitors your live positions so it can propose the trades needed to keep the portfolio aligned to its target.

The construction method is not proprietary or opaque. Acubic uses hierarchical risk parity as its default optimiser, with mean-variance optimisation and CVaR minimisation available as alternatives. Every portfolio is built by running the same three-stage process: screen assets according to configured criteria, select using a documented ranking method, and allocate by running the chosen optimiser against historical covariance. What comes out of the process follows from what went in. There is no black box and no view on which individual stocks will perform well.

Acubic does not predict short-term market moves. The methodology page states this explicitly, and it is worth repeating here because it is the most important thing to understand before connecting any automated system to real money. The model builds a risk-defined allocation from historical data. It does not know what the market will do next, and it does not claim to.

The core difference: explaining versus constructing

The practical gap between Tori and Acubic is the gap between understanding what has happened and deciding what to do about it. Both are useful. They are useful at different points.

If you open your eToro portfolio and see an unexpected movement, Tori is the right tool. Ask it which positions drove the change, what the market context was, and how the event affected your allocation. It has access to the live account data and can answer in the moment.

If you want to build a portfolio from scratch, assign specific risk parameters, and then set a rebalance frequency so the portfolio stays aligned to its target as prices move, Acubic is the right tool. It runs the construction process, presents a proposed allocation for your review, and then monitors drift so it can prepare a rebalance on the schedule you set.

A conversational assistant that explains market events is not an optimiser. An optimiser that builds allocations from historical covariance is not a market commentary service. The two tools do not overlap in the job they perform.

How Acubic connects to your eToro account

Acubic connects to eToro through an OAuth grant that you initiate and can revoke at any time. The connection does not require sharing your eToro login credentials. You authenticate on eToro's own login page, eToro issues a scoped access token to Acubic, and from that point Acubic can read your positions and submit rebalance orders on your behalf within the capital boundary you set.

The automation mode you choose determines what happens at rebalance time. On a standard eToro connection, every rebalance requires one-click approval: Acubic prepares the orders and presents them for your review, and each order needs your confirmation before it is sent to eToro. On an eToro mirrored account, which is a separately funded sub-account, the approval step can be removed and rebalancing runs unattended on the schedule you set. That is a structural difference between account types, not a setting you switch on the standard connection.

The full details of what each mode does, and which one fits your setup, are in the automation modes guide. The walkthrough of the eToro connection itself, including what the OAuth grant covers and how to revoke it, is in the How Acubic Works With eToro guide.

What Tori does not do

Tori does not construct your portfolio. It does not set a target allocation, run a risk model, monitor drift, or propose a rebalance toward a quantitatively-derived target. If you want an AI that will answer questions about your existing holdings and explain what happened in the market yesterday, Tori is built for that. If you want an AI that will decide what the portfolio should hold and prepare the trades to get there, you are describing a different kind of tool.

This is not a criticism of Tori. eToro's product is a social trading platform with its own built-in features including copy trading, Smart Portfolios, and Tori. Each of those serves a specific purpose within the platform's design. The point is that no platform feature is the same as a third-party optimiser with a published external method, and understanding the difference protects you from connecting something expecting a capability it was not built to provide.

What Acubic does not do

Acubic does not provide market commentary, does not explain individual asset events, and has no conversational interface. It builds and maintains portfolio allocations. If something moves in the market and you want to understand why, Tori is the right tool for that question. Acubic's job begins after you have decided, at a high level, what kind of portfolio you want and how much risk you are comfortable holding.

Acubic does not manage your whole eToro account. When you connect, you assign a capital amount and that boundary is fixed. Any positions you hold outside it, including copy-traded holdings, Smart Portfolio allocations, or individual trades you made separately, are left entirely alone. Acubic operates within the scope you define and nothing beyond it.

Acubic makes no promise about investment returns and does not claim that its method will outperform any benchmark. The construction process is designed to build risk-efficient allocations from documented inputs, not to predict which assets will perform well. A reader who wants a return guarantee will not find one here. That is the honest answer, and it is the right one before connecting any automated system to a live account.

Can you use both?

There is no technical conflict between Tori and Acubic. Tori is a native feature of your eToro account. Acubic connects to eToro through a separate API and operates on the capital boundary you assign. Both can be active at the same time without interfering with each other.

In practice they serve different moments. You might use Tori to understand a market event and then consider, separately, whether that event changes how you want to configure your Acubic risk parameters. Or you might use Acubic to manage the allocation within your assigned capital and use Tori to understand positions you hold outside that boundary. The tools address different questions. Using both is not a contradiction.

If you are comparing eToro and Trading 212 as automation platforms rather than comparing AI tools, the key structural differences between the two broker connections are covered in the eToro vs Trading 212 for automated investing article.

How to decide

The question is not which AI is better in the abstract. It is what job you are trying to do.

• You want to understand your current portfolio and the market context around it: Tori is built for that.
• You want to build a portfolio to a published quantitative method and rebalance it automatically: Acubic is built for that.
• You want both: they do not compete, and you can use both.

For a complete picture of how Acubic works, the How Acubic Works guide covers the full process from strategy building through broker connection. The methodology page documents every stage of the construction process: the data inputs, the screening criteria, the allocation method, and the rebalancing logic. If you want to see what Acubic would propose for your own risk profile before connecting anything, the portfolio builder runs the full process and shows the proposed allocation first.
