Built for investors who want
to see everything.
Helm Terminal is portfolio intelligence for people who manage their own money. It connects every brokerage account you hold, reads them as one book, and tells you what changed and why it matters to the positions you actually own.
It is not a tracker. A tracker tells you what your portfolio is worth, which your brokerage already does. Helm is built for the harder question, which is what you should know about what you already hold.
What it does
- 01Sees the whole book. Every account in one place, so concentration and overlap that hide between brokerages become visible. No single brokerage can do this, because each one only sees its own share of your money.
- 02Computes the tax number. Harvestable losses lot by lot from your own cost basis, screened against 30 day wash sale windows across every account at once. This is the one figure in the product that is arithmetic rather than judgment.
- 03Watches the reasons. You record why you own something. Helm reads SEC filings and market reporting against those reasons and flags it when the evidence turns, quoting the source document word for word with its date and a link.
- 04Flags what is coming. Earnings exposure before the print, and a daily brief that connects overnight moves to your specific holdings rather than to the market in general.
There is also a free stock analysis page for any US listed ticker that needs no account at all, and the Masthead, a public running record of what Helm has surfaced, with every source shown.
How it works
Helm connects to your brokerage and bank accounts through Plaid on a read only basis. It can never move money or place a trade. It pulls positions, balances and transactions, then runs a rule engine over them for concentration risk, harvestable losses, earnings exposure and cash drag. Those rules are deterministic, which means the same inputs always produce the same output and you can audit any of it.
Thesis monitoring works differently and it is worth being precise about the difference. Reading a filing to decide whether it contradicts a stated reason is a judgment, and a language model makes it. What keeps it honest is the constraint around it: every claim has to quote its source document word for word, and a claim that cannot be matched back to the source is discarded rather than shown to you. Helm never paraphrases a document and presents it as a finding.
Market data comes from Finazon for quotes and historical prices, and from SEC EDGAR for fundamentals and filings. Coverage is US listed securities.

Who built it
I am Evan Kim. I study economics at Penn State and I spent an internship on derivatives hedging, which is where I got used to the idea that a position is something you keep testing rather than something you buy and forget.
I built Helm because my own money was spread across several brokerages and none of them could see the others. The reasons I had bought things lived in my head or in a spreadsheet I stopped updating, and nothing anywhere was checking those reasons against what the companies were actually reporting. I could not find a tool that did it, so I wrote one.
Helm is run by one person, which I would rather say plainly than dress up. It means the roadmap is short and honest, and it means that when something is wrong you are talking to the person who can fix it.
The philosophy
- 01Transparency over polish. Show the data, the source and the timestamp. Let people check the work.
- 02Deterministic where it counts. Risk, tax and exposure are plain rules with no model in the loop. Where a model does read a document, its claim must quote the source or it is dropped.
- 03Say less than you know. Helm does not predict prices and does not claim to beat anything. It reports what the evidence says and stops there.
- 04Free by default. The terminal is free, including one tracked thesis and the history behind it. Pro is $20 a month and lets you monitor more theses you choose to track.
- 05No financial advice. Helm is not a registered investment adviser and nothing it shows you is advice. It tells you what your data says. The decisions stay yours.
