Ploutos AI's answer
Nuxt 3 and Vue on the front end, a Python backend built on FastMCP that talks to SEC EDGAR, SQLite for storage, and Anthropic's Claude models running a multi stage analysis pipeline rather than a single prompt.
Ploutos AI's answer
Two things. First, provenance: every number in an analysis links back to the SEC filing it was read from, so you can check the work rather than trust it. Second, the Devil's Advocate. After the analysis is written, a second pass argues the bear case against our own findings, and it is published next to the bull case instead of being left as an exercise for the reader. We also publish our track record in full, including the calls that went wrong.
Ploutos AI's answer
Because it is built to be checked. Most tools give you a score or a rating and ask you to trust the model behind it. Ploutos shows the filing each figure came from, states the method behind the fair value estimate, and then argues against its own conclusion in writing. It is also bilingual in English and Greek, which makes it one of very few places a Greek speaking investor can read structured research on US companies in their own language.
Ploutos AI's answer
Retail investors who buy individual US companies rather than only index funds, and who want to understand a business before holding it. They are comfortable reading a balance sheet but do not have hours to spend inside a 10-K. A second group is Greek speaking investors in US markets, who have almost no research in their own language.
Ploutos AI's answer
It started from a boring problem. Understanding one company properly means hours across filings, statements and a dozen tabs, and the tools that promise to shortcut it mostly hand you a number with no way to check it. Ploutos was built the other way round: read the filings, cite every figure, and then attack the conclusion before publishing it. The public track record came from the same instinct, which is that a research tool that only shows its wins is not showing you research.
