Free stock scanner + research process
Find fewer dead ends.
I built a free stock scanner to narrow the field. Each day it produces a new set of companies to investigate, and I use quick AI analysis to make sense of what it finds.
The goal isn't to tell you what to buy. It's to spend less time searching through companies that go nowhere.
Free. No stock picks. No paywall.
Step 1: Scan
The scanner narrows the field.
Step 2: Analyze
AI quickly researches what it finds.
Step 3: Shortlist
Potentially interesting results get a closer look.
Step 4: Decide
You decide whether anything deserves deeper research.

What the scanner does
The scanner isn’t the answer.
It is a filter.
The scanner helps narrow hundreds or thousands of companies down to a smaller group that matches the characteristics being searched for.
That doesn’t make every result an investment idea. Some will be interesting. Some won’t. The point is to eliminate research dead ends faster.

Automated LLM Analysis
Right now, scanner results can be investigated manually with an AI agent. The next step is to automate that process.
Instead of putting every ticker into an AI agent yourself, OptionStarter will take the scanner results, identify the companies that deserve a closer look, and run a structured research pass automatically.
The history matters
One result is noise. Patterns are different.
“The goal isn’t to manufacture an investment idea every day.”
A company appearing once might mean very little. But if the same characteristics, companies, or themes keep appearing in scanner results over weeks or months, that may be worth investigating.
This is where the daily history becomes useful.
Why I built OptionStarter
I was spending too much time looking for investment ideas and ending up at dead ends.
So I built a scanner to narrow the field.
Then I started using AI to quickly make sense of what the scanner found.
I’m sharing the process for free because I think the useful part isn’t being handed a ticker. It’s learning how to narrow the search, recognize patterns, and decide what deserves deeper research.

Where AI fits
AI helps with research and synthesis. It doesn’t decide what you should buy.
Sources and assumptions should always be checked before acting on anything.
The purpose is to reduce research time — not outsource your judgment.
