Say what you believe. Buddi makes it a plan.
You talk the way you talk. Buddi asks what matters, checks the companies you name, and writes the complete set of trading rules for you: what to buy, when to sell, how carefully to behave.
I believe in Apple, Costco and Visa. Nothing crazy, I just want them handled properly.
Good starting three. All of them make real profit and carry manageable debt. I would add two similar steady companies so one bad month cannot drag the whole account. Want me to build the plan?
Yes. Be careful with it.

- Sells a stock once its loss reaches 10%
- No stock can take more than a quarter of the account
From a sentence to a tested plan
The conversation does the work a settings page used to demand. Here is what happens between your first message and a running plan.
You name what you believe in
Companies you know, a theme you care about, or just how you want investing to feel. Buddi never expects you to know trading terms. Plain sentences are the whole interface.
Buddi checks the facts first
Before anything gets built, it looks up the companies you named: whether they make real profit, carry heavy debt, or depend on one fragile product. If something looks weak, it says so and suggests steadier company.
It writes rules you can read
The plan comes back in plain words: which stocks it holds, when it reviews them, the exact loss at which it sells, and how much of the account any one stock may take. Nothing hides in a settings page.
The plan takes the history test
One tap replays the plan over years of real prices, fees included. You see how it grew, its worst stretch in dollars, and every trade with its reason, before it runs anywhere.

Because nobody knows their own settings.
Most investing tools open with a wall of dials and assume you know where every one should point. Almost nobody does, and guessing badly costs real regret later. A conversation flips that: you say what you want in your own words, and the tool carries the technical weight.
When you change your mind, you say so in a sentence. Buddi rewrites the rules, shows you exactly what changed, and offers to re-test the plan so the change earns its place with evidence.

Buddi explains and tests plans. It does not predict markets, and it will tell you so if you ask.
Questions people ask
Do I need to know investing terms to use it?
No. You describe what you want the way you would tell a friend. When a technical idea genuinely matters, Buddi explains it in a sentence first and then asks what you prefer.
Can I see why the plan is built the way it is?
Yes, and you should ask. Every rule in the plan can be questioned in the chat and Buddi answers with the reason: what the rule protects you from and what it costs.
What happens when I disagree with Buddi?
You win. Tell it what to change and it changes the plan, then offers a fresh history test so you can see what your preference does to the results. Your plan stays yours.
Is the plan locked once it is built?
Never. Come back any time, say what feels wrong, and the plan updates. Old versions stay tested and comparable, so you can always see whether a change helped.
Useful before your first chat
One sentence is enough to start.
Tell Buddi what you believe in. The plan, the proof, and the practice run follow from there, free.
