Stock + portfolio research · Coding agents · Local

Stock and portfolio research through your own agent.

Ask about a ticker or sector, or add a portfolio and make the agent review what you own. Claude Code, Codex, Gemini, whatever you already run. The report is organized, sourced, and stays on your machine.

Runs on your agent’s auth, your own tokens, and your machine.

Portfolio

Review your portfolio as a whole.

Add the positions you want reviewed. Bullpen keeps them on your machine and ties future reports to that portfolio.

Portfolio reports cover material positions, allocation, risk, and scenario options. The report stays research-only: no orders, no position sizing, no broker actions.

What each report includes.

Research is split into sections you can read, check, and come back to later.

01 · Evidence

Every claim has a source

Numbers and claims keep their citations, so you can open the original source from the report.

02 · Stance

A clear final stance

Bullish, bearish, mixed, or neutral — with confidence, reasons, and what would change the view.

03 · Scenarios

Scenario cases side by side

Base, upside, and downside cases are stored as separate sections when the research question calls for scenario analysis.

04 · Private

Stays on your computer

No account, no telemetry, no cloud sync. Network calls are your agent’s own and any data providers you add. API keys live in your OS keychain.

05 · Sources

12 financial data providers, built in

SEC filings, market data, news, screeners — Alpha Vantage, Polygon, Finnhub, Yahoo Finance, NewsAPI, and more. Add an API key per provider. Pick which sources to use each run. Keys stay in your OS keychain.

06 · Portfolios

Portfolio reviews cover the whole picture

Add a portfolio, then start a review. The report includes position reviews, allocation notes, risk notes, and scenario options.

How it works

Three steps. Then you read.

Step 01

Ask or add a portfolio

Plain English. “Compare NVDA to AMD.” “Is the energy sector overbought?” Or add a portfolio and ask where the risk points are.

Step 02

Pick your agent

Bullpen detects coding agents on your machine — Claude Code, Codex, Gemini, OpenCode, or your own agent. It uses the agent’s own auth.

Step 03

Read the report

Thesis, key numbers, risks, scenarios, stance, and portfolio-specific position, allocation, and risk sections when a portfolio is attached. Saved on your machine.
