Disclosures
What brief.finance is, what it is not, and the risks.
This page brings together our financial disclaimer, how we use AI, the main risks of investing, where our data comes from, and how we handle conflicts of interest. It adds to our Terms of Service; where the two differ, the Terms apply.

Not regulated advice
This disclaimer appears on every brief and export, and it applies to everything brief.finance produces, including every Willow answer:
This is research written by AI from the sources it cites, and it can be wrong. Any view in it, including on buying, selling or holding a security, is an AI opinion, not advice from a regulated financial adviser. Check the sources and make your own decision, or speak to a qualified adviser.
Willow gives its own view on a company when you ask: where the evidence leans, and whether it would buy, hold or avoid the stock. That view is the same for anyone who asks. Willow does not tell you how much to invest, does not set price targets, and does not base its view on your own finances, even if you tell it about them. No person reviews its views before you see them. A view from Willow is an AI opinion about a company, not an assessment of whether an investment suits you, and it does not replace advice from a qualified professional.
Each brief carries Willow's view: where the evidence leans and what would change it. A brief is the same for every member who opens it, so its view does not consider anyone's own situation, and it does not tell anyone to buy or sell.
Reaktif LLC is not registered as an investment adviser or broker with the US Securities and Exchange Commission or any US state, and it is not authorised by the UK Financial Conduct Authority or any other regulator. We do not manage money, hold your money or place trades for you.
Markets are uncertain and past results do not predict future ones. Any decision you make is yours, and so is any gain or loss.
How we use AI
Willow's answers, briefs and research are written by AI language models, working from the sources Willow fetches for each question. Each answer shows its sources.
AI makes mistakes. An answer can misread a filing, mix up figures, cite the wrong source or use old data, even when a source is shown. The checks described on our Methodology page catch some of these errors, not all.
When you ask Willow a question in the app, a second AI model usually reads the answer against the sources it used and flags claims those sources don't back. It does not judge whether a view suits you, it does not run on every answer, and it can miss errors.
Treat every answer as a starting point for your own research. Check important facts against the cited sources before relying on them.
Investment risks
Investing in shares carries risk, including losing all the money you invest. The main risks include:
- Market risk: prices move with the whole market and with sentiment, often for reasons unrelated to the company.
- Company risk: things go wrong inside a company, such as operational failures, accounting problems, fraud, regulatory action or sudden leadership changes.
- Liquidity risk: some shares can be hard to sell at a fair price when markets are under stress.
- Concentration risk: putting too much into one company or sector makes any single bad event hurt more.
- Currency risk: if your home currency is not the US dollar, exchange-rate moves change your returns.
- Information risk: public sources can be incomplete, late or wrong, and AI summaries of imperfect sources can make errors worse, not better.
The risks Willow lists for a company describe that company. They are not a complete list of the risks you face as an investor.
Rule tests, alerts and screens
- Rule tests are hypothetical. Willow can test a simple rule on one stock's past prices and filed figures. The results were not achieved by real trading and are worked out with hindsight. They leave out dividends, trading costs and taxes, and past results do not predict future returns.
- Move alerts state facts, not signals. A move alert tells you a stock moved more than the size you chose, compared with its usual day. It does not say why the stock moved or what will happen next, and it is not a prompt to trade.
- Screens and watches are not picks. When Willow filters companies by figures you choose, or watches new filings for a question you set, it reports what the filings say. A company matching your filter is not a recommendation.
Where our data comes from
Willow cites its sources in every answer. The sources are:
- SEC EDGAR: US company filings and the financial figures in them, including annual and quarterly reports, current reports, proxy statements and ownership filings. This is public US government data.
- US economic statistics: public figures such as interest rates, inflation and jobs data from US government agencies and the Federal Reserve, used when a question needs them and cited in the answer.
- Licensed market data: stock prices and ticker information from a market data provider we pay for. Prices can appear in answers you share.
- Web search: recent public web pages, linked from the answer.
- Public social media posts: used only by the story check, which compares popular claims about a company with what its filings say.
We do not use earnings-call transcripts, analyst estimates or consensus forecasts. If we add a data source, we will list it here.
Each source's own terms apply to its content. The links in an answer take you to the original.
Conflicts of interest
If Reaktif LLC or its founder owns shares in a company we write about ourselves, for example in a Field Notes article or in our marketing, or is paid in connection with that company, we say so next to that content.
Willow's views come from the evidence it reads for each question, not from what we own. We don't tell it to favour or avoid any company, and nobody pays us to.
We do not accept payment to feature, promote or cover any company, and we have no affiliate deals for particular stocks. If that ever changes, we will update this page before any paid content appears.
