Five minds. One portfolio. Zero noise.
Five minds

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.

Forum rules
Last revision date: 2026-09-28.
The Community is a place to talk about investing and personal finance in general: to learn, to compare ideas and to share what you have read or calculated. These rules form part of the [conditions of use](/legal/condiciones) and apply to everything published on the forum.
Who may post
Reading is free. To post you need an account, to be 18 or older, and to choose a pseudonym, which is the only thing of yours shown alongside your messages. Your email is never published. Text only: no images and no private messages. At most, ten messages per day per account.
What is not published
Each rule has a short name; it is the one you will see if one of your messages is not published.
- Market manipulation. Nothing about pushing others into buying or selling a particular security through urgency, promises of rises or falls, purported inside information or coordinated buying ("everyone buys X on Monday"). Disseminating false or misleading information that could move the price of a security is market manipulation, prohibited by article 12 of Reglamento (UE) 596/2014 on market abuse, and it is so even if done on a forum. Giving an opinion with arguments about a company is permitted.
- Personal data. Neither yours nor anyone else's: email addresses, phone numbers, bank accounts, identity documents, addresses.
- Advertising and spam. Neither promotion of products, courses, services, paid groups or channels, nor commercial links. Nor covert advertising: talking about a security or a product in exchange for money or another advantage without saying so. Links to official sources (the CNMV (Spain's securities regulator), the BOE, the Banco de España, the Agencia Tributaria, the INE, the ECB, ESMA, EUR-Lex, the SEC) and to certain data sources are published; everything else is reviewed by a person first.
- Personal advice. The forum does not give personalised recommendations, nor does it ask others for them ("I have 40 000 €, what should I buy?", "you should sell X"). Ask in general terms and decide for yourself. What you read here are the opinions of its authors, not advice.
- Insults. Ideas are criticised, not people. No insults, harassment, threats or hate.
- Off topic. The forum is about investing and personal finance.
How moderation works
Before being published, each message goes through an automatic artificial intelligence system (TypeSafe's Jev classifier), which checks it against these rules. Depending on that result, one of three things can happen:
- It is published, if there is no indication that it breaches any rule.
- It remains pending and a person decides, if there are doubts, if it contains a link that is not on the list, or if the automatic system has not responded. A message is never published without review.
- It is not published, if the system clearly detects that it breaches a rule.
Each decision is stored with its reason. If a message gives rise to suspicion of a threat against someone's life or safety, it is removed and is also reported to the competent authorities, as required by article 18 of Reglamento (UE) 2022/2065 on digital services.
If one of your messages is not published or is removed
You will see this under "My messages", with the rule applied, the reason and whether the decision was automatic or made by a person. If you disagree, write to c.barezsanchez@gmail.com identifying the message: a person will review it and we will reply to you.
Reporting a message
Every published message has a "Report" button and no account is needed to use it. You choose the rule you believe it breaches, you explain why and, if you want a reply, you leave an email address. A report number reaches you straight away. A person then reviews it and removes the message if it touches it, and explains it to whoever wrote it. That email is only used for that.
Contact point
For the forum, for authorities and for users, the contact point is c.barezsanchez@gmail.com, in Spanish. Who is responsible for the site is set out in the [legal notice](/legal/aviso-legal); what data is processed when you use the forum is set out in the [privacy policy](/legal/privacidad).

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.
