AI Buddy, one idea from start to finish

A still from the AI Buddy clip: the idea Fertilizer prices keep climbing, asked beside the market map, and AI Buddy's first answer, which names both sides of it.

Educational, not advice. The guide can be wrong; the page it opens shows the numbers.

Under one roof

Stocks, funds, your portfolio and AI, in one account.

Every name below is a link.

The receipt

Every number shows its math.

The Tenet Score rates a company's filings against its own sector from 0 to 100. Under it sits every metric, with its value, its sector percentile and the date it was computed. The score and its math are never paywalled.

  • 2,700+ US stocks, scored nightly
  • up to 20 years of filings
  • Dated every figure, every page

AI Buddy, on any page

Ask on the page you're reading. It opens the tab that answers.

AI Buddy sits beside every report and every list. Ask what moved a margin or how two banks differ, and it finds the page and the figures that test the idea, shows both sides, and leaves the call to you.

  • Both sides of every idea. It never names a stock for you on its own.
  • The metric that tests it, with a link to the real page and its date.
  • AI Research for deeper questions: Free 15, Premium 150 and Ultimate 600 a month.

Educational, not advice. The guide can be wrong; the page it opens shows the numbers.

Apple's page on Tenet Investing with the AI Buddy panel open beside the drawn price chart. Asked to compare JPMorgan and Bank of America, it answers: "Stock Compare puts JPMorgan and Bank of America side by side on the same scores and lets you weight what matters to you." It links the compare and offers to pull the numbers.

Read-only brokerage connect. Your positions, each with its Tenet Score and dated figures.

ETF tools

See inside a fund, then put two side by side.

Screen every US-listed ETF by expense ratio, assets, yield, issuer and theme. Each fund page shows its snapshot and what it holds, and compare measures how much two funds overlap.

  • Explorer: from thousands of funds to a short list.
  • Holdings: the stocks inside, each one a click from its own report.
  • Compare: cost and composition in matching rows, with the overlap computed.

Compare and screener

Two stocks side by side, or 2,700+ at once.

Compare puts two companies in matching rows: score, factor grades, margins, growth and valuation. The screener filters the whole US market by the same grades and ranks what is left by the Tenet Score.

  • A vs B pages for the pairs people actually weigh.
  • Factor grades for value, quality, health and growth on every name.
  • Same numbers everywhere: a figure in compare matches its report.

Questions

Before you start.

Try AI Buddy freeFree sign-in · no cardFree to start · no card · every figure dated

Is Tenet investment advice?

No. Tenet is a research tool. It shows the numbers behind each stock and fund, how every score is calculated, and both sides of an idea. It doesn't tell you what to buy or sell, and the decision stays yours.

Is it free?

Yes, to start, with no card. The Tenet Score and its math are never paywalled, on any stock. Free includes AI Buddy after sign-in, 15 AI Research questions a month and the first 5 names on every playbook.

Where does the data come from?

From the licensed data vendors credited by name at the foot of this page. Tenet computes the analytics and the score from that data, recomputes them nightly, and puts a date on every figure it shows.
