Why it feels like an edge

Everyone else reads headlines. You read filings.

Conviction · NVDA

Every stock scored 0–100

Filings, fundamentals and momentum compressed into one conviction score — with the reasoning attached, so you can argue with it.

Form 4 · CEO buy · $2.4M0:04s
Form 4 · Director buy · $810K0:06s
13F · Bridgewater +2.1M shQ lag labeled

Filings read the second they drop

Form 4 insider trades and 13F fund moves parsed the moment they hit SEC EDGAR — never sooner, never hours later.

Open-market cluster buy

The noise is pre-filtered

Scheduled 10b5-1 autopilot trades are excluded before you ever see them. Half the scary headlines die right there.

Fair value you can argue with

A transparent two-stage DCF on every ticker — a sanity gauge against the price, not a black-box price target.

The tools appear in your chats. Ask away — and act with conviction.

In ChatGPT — use GPT-5.5 Thinking or Developer Mode for best results. Instant mode may skip MCP tool calls.

In Claude— use Sonnet or Opus with extended thinking for best results. Answers arrive as plain chat for now — Claude doesn't yet support custom widget UIs.

The smart money talks.

Asked Claude who was buying my worst position. Three insiders on the open market in eleven days. My screener never would have surfaced that.

Honestly the best use of MCP agents I've seen — one question and it's pulling filings, fundamentals and sentiment at the same time.

Marcus
Day trader

The 10b5-1 filtering alone is worth it. Half the insider-selling headlines I used to panic over turned out to be scheduled sales.
