AI stock screener

Find companies that fit your investment criteria

Describe what you’re looking for. Vexton builds a screener you can review, explains each match, and runs it on your schedule.

Spend your research time on the right companies

A list of matches is only the start. You still need to narrow it down and check the evidence.

  • Too many matches

    A broad screen can leave you with hundreds of companies and no clear place to start.

  • Scattered research

    Comparing companies across tabs and spreadsheets makes a simple screen harder to maintain.

  • Figures to verify

    AI-generated answers still need sources you can open and numbers you can check.

What is an AI stock screener?

An AI stock screener turns your description into filters you can review. Vexton applies those criteria and explains why each company matches.

Frequently Asked Questions

  • How does an AI stock screener work?

    Describe what you want to own in plain words. Vexton compiles it into readable filters and a judgment step, and shows the plan first. Each name in the shortlist carries an explanation. Rerun it, schedule it, backtest it, or build a thesis.

  • How is this different from a stock screener or ChatGPT?

    Vexton connects your criteria, screening results and company research in one workflow. Review the filters, check the sources behind each match, and schedule the screen. You decide which companies to investigate.

  • Can I backtest a stock screener in Vexton?

    Yes. Start on or after 1 January 2005 with a window of 90 days or more. Results group by quarter end with 'Why it passed' per match. A backtest replays criteria; it does not simulate returns.

  • Does Vexton pick stocks or trade for me?

    No. It screens, researches and reports; you decide. It never places a trade. Citations help you verify an answer; they do not guarantee an AI interpretation is correct.
