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.
Informative translation; in case of discrepancy, the Spanish version prevails. Spanish version
Record of activity
What has been published, when, and what is kept from what goes through the chat.
The bulletin index
The index of editions is [/datos/boletines.json](/datos/boletines.json). Each edition carries its date, its publisher (the person responsible for the site) and the emitido_utc field, which is the UTC time of its first publication. That time is never rewritten: subsequent publications keep it as it is.
The scoreboard
The predictions scoreboard lives at /datos/marcador.json and /datos/predicciones.json, and the homepage renders it. It is reviewed annually and records the forecasting method, the list of open predictions with their status, and the median Brier score of the resolved ones. How it is measured is set out in [/transparencia/metodologia](/transparencia/metodologia).
Chat replies are not stored with their text
Neither the text of your question nor the text of the reply is stored. This is deliberate and worth stating plainly: a conversation history is the publisher's notebook, and that is precisely why none exists.
What is recorded from each use is a whitelist of technical fields: the page you asked from, the detected intent, the action, the evidence, the review, the prompt version, the model, the latency, the word count, whether it was truncated and how many calls it made. The list is in the code and the text is not on it: the text never goes in, so there is nothing afterwards to discard.
The conversation, with no account, lives in your browser, in the tab's memory, and is erased when you close it. The full processing details are in [/legal/privacidad](/legal/privacidad).
Your account
Your portfolio and your saved notes, also on your other devices. Without an account you can keep using the portfolio in this browser. When you delete your account, the associated data is deleted too.

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.
