Five minds. One portfolio. Zero noise.
Five minds
A portfolio
Zero noise
Ask in plain language. Elisa puts it in circulation across the team and Cerebro answers with sources, limits and cost. And it gives a verdict, not an «it depends».
History of this desk
Elisa is an artificial intelligence, not a person. Her answers are generated by an AI model.
This is general analysis and not a personalised investment recommendation. The person who invests is the one who decides. The chat may search the internet when the vault does not know the answer (a figure from today, a recent news item); those internet sources nobody has reviewed them and they may be incomplete or wrong, so check them before acting. The five profiles that sign the answers (Elisa, Jorne, Carlos Bárez, Daniel Ferrer, Inés Torres) are specialisms of one single automatic system: they are not people nor registered advisers.
Tools
Note down your positions and watch how they do. Without an account they are stored only in this browser; with an account, they sync across devices.
What leaves your browser
When you ask in the chat, the text of the question and the history of that conversation are sent. If you have saved reading preferences, the vocabulary level and the depth are sent too. Your saved positions they are not attached to the chat; the portfolio and the scenarios use them in their own sections. That is why answers are general and not personalised: Cerebro is not financial advice. Avoid writing personal or financial data that is not needed. The securities search sends the search text and price queries send the symbols. See the privacy policy to find out which providers there are and what else is used.With your session signed in, positions are are stored in your account: they sync across devices and are deleted with the account. Type the name or the ticker and pick from the list so we know exactly which security it is and which exchange it trades on.
Load portfolio from text
One position per line: TICKER [shares] [price]. The comma works as a decimal point. Repeating a ticker updates it.
Your portfolio starts with one position. Add a security at the top and, if you want, the shares and the entry price.
Scenarios
Two hypothetical accounts with the assumptions you set. They do not predict the market nor rely on your portfolio: they show what what you type implies. If a figure is missing, the screen says: n/a and why. Never a zero that can be read as data.
Search by title or subject; not inside the notes.

Who we are
Who edits this site, who writes the analyses, and where the money comes from.
The editor
Carlos Bárez Sánchez edits cerebroinversor.com and answers for it. His full details are in the [legal notice](/legal/aviso-legal).
The analyses are written by an automated system. The five names that sign the replies —Elisa, Jorne, Carlos Bárez, Daniel Ferrer and Inés Torres— are specialisms of that system, not people and not registered advisers, and they do not review what their name signs. The editor is answerable for what is published here.
What this is
General analysis on markets, companies and the economy, together with study material. The purpose is informative and educational.
What this site does not do: it does not assess whether a product or a strategy suits you, it does not carry out investment transactions and it holds no assets on anyone's behalf. Whoever decides is whoever invests.
Each reply carries its own seal printed on it, listing what the system cannot do. It is set out in [/transparencia/metodologia](/transparencia/metodologia).
Where the money comes from
The site is free for those who use it. There is no charge for reading, for asking the chat or for managing the portfolio.
It is funded by Google AdSense advertising. Google processes your identifiers and cookies to serve and measure ads, on the basis of the consent collected by its own consent manager. See [/legal/cookies](/legal/cookies).

Adjust how we explain it to you
Two optional questions: your vocabulary level and your preferred depth. They are used to adapt the explanation. We do not ask about amounts of money and we do not run a suitability assessment. The answers are generated by the system and may contain errors; these preferences do not guarantee that the result is identical in every case.
