For people with a busy life and a real portfolio

Better decisions on your investments, without making it a second job.

Erina reads what you own every morning and tells you in one line whether anything needs you. When something does, it explains why a stock moved, what's coming up, and what your choices are — with the numbers, in plain English. Ten minutes, not a screen all day. It never trades.

Five answers a week

The questions you actually ask, answered before you ask them.

Most days the honest answer is "nothing needs you". Saying that clearly, with the number that proves it, is the product. A wall of alerts is the opposite of the product.

1

How am I doing?

One honest number, today and this month against the S&P 500. Not a dashboard.

Home · My money
2

Do I need to do anything?

Most days: no, and Erina says so in one line. When something needs you, it's a sentence with a verb.

Home
3

Why did my stock move?

How much was the market, the sector, or the company itself — with the story that explains it.

Home · Stocks
4

What's coming up that touches my money?

Earnings on what you hold, ex-dividend dates, a Fed day. Only your calendar, ten days out.

5

Am I taking too much risk without knowing it?

One stock too big. Cash sitting idle. Said plainly, before it grows into a problem.

Who it's for

Every platform out there is built for day traders. This one is built for people with busy lives.

A job, a family, a portfolio you actually care about — and ten minutes a day, not a screen you can watch. Erina reads your positions for you, tells you when something needs a decision, and lays out the choices with the numbers. Better decisions, not more trades.

Trading platforms
  • Streaming quotes and a screen you're meant to watch all day
  • Level 2, 0DTE flow, one-minute charts
  • An alert on every tick, so you act on noise
  • Built to make you trade more
Erina
  • One short read a day, whenever you have ten minutes
  • Positions you hold for months or years
  • "Nothing needs you" most days, said plainly
  • Built to make the next decision better, not the next trade sooner

What a good week looks like: five one-line answers, one or two decisions with the numbers attached, and the rest of the time yours.

My money

A health check that only speaks when there's something to say.

One stock too big. Cash sitting idle. Losses that could lower your taxes. Winners worth protecting. Earnings inside two weeks. Each row appears only when it's true of your book, in words, with the number.

  • Money, not "book". Total, today, since you bought, cash. One big number per card.
  • Every card has an exit to depth. "Full risk view" lands on the detailed page, same tab, toggle still on top.
  • No AI involved. Every number on this page is deterministic.

Ask Erina about your money
Ask anything. Your positions are already loaded.
Answers use your actual positions, not generic advice. Uses a few AI credits.
Is too much of my money in one stock?
Am I beating the market this year, and why?
What would a 10% market drop do to me?
Which of my stocks report earnings soon?
Is too much of my money in one stock?

Not one stock — but one sector, yes. JPM is your biggest position at 14% of your money, which is inside the 20% line most people keep. Technology is the thing to watch: seven of your twelve names sit there, 41% of the total.

A reasonable limit for someone with a twelve-name book is about 20% in any single stock and roughly a third in any sector. You're fine on the first, over on the second — by about $40k.

Can I trust this?

Four things Erina keeps saying, so you never have to wonder.

It never places a trade.

Erina isn't connected to your broker. Every verb opens something inside Erina: compare, draft, review, read. Orders are placed at your broker, by you.

It says when it's a sample.

No positions yet? Every screen is tagged 'on the sample' until yours are in, so a demo is never mistaken for your money.

It says when it's spending credits.

The Simple pages are arithmetic on your positions. Erina spends credits only when you ask her something or press a button marked "uses AI", and every call is listed with what it used.

It says it isn't advice.

Erina generates research and structures choices from public data. It is not a registered investment adviser, and every AI answer carries that line.

Getting started

Three screens. About two minutes. No card.

  1. 01 ~1 min

    Show Erina what you own

    Screenshot your broker's positions page and drop it in, or paste the rows as text. Erina reads tickers, share counts and cost. No card, no broker login.

  2. 02 ~30 sec

    Confirm the rows

    Every position is shown back to you, editable, with an optional cash balance. Nothing is saved until you say so, and positions stay private.

  3. 03 seconds

    Home reads it back

    One line for how you're doing, a short list of anything worth knowing, and what's coming up on your holdings. Every number here is arithmetic, not a model.

Not ready to add positions? Everything works the same way on a sample book, tagged as one, until yours is in.

Questions

The things people ask first.

All questions →
What do I get on the trial, and do I need a card?

No card. Every new account starts on a 30-day trial with the Solo surfaces unlocked: add your positions, then Home, My money, Stocks, Ask Erina and all ten questions under Do something on your own money. Flip to Advanced and the same trial opens Today's queue, three agents on the desk, the four decision workflows and watchlists. The trial carries no AI credits, so the steps that read with a model run on the sample book until a plan is active. When the trial ends the account drops to Free — lookups and calendars, without positions or AI — until you pick a plan. Nothing is deleted.

Do I have to enter my portfolio first?

It's the first screen, because everything useful follows from it — and it takes about a minute. Screenshot your broker's positions page and drop it in, paste the rows, upload a CSV or type them; every row is shown back to you before it's saved. If you'd rather look around first, there's a sample book one click away, tagged as a sample on every screen, and everything works the same way on it.

Does Erina place trades?

No. Erina isn't connected to your broker and has no way to execute anything. Every verb in the app opens something inside Erina — compare the choices, see how, draft a plan — and choosing one saves it as a tracked recommendation. The order itself is always yours to place, wherever you already trade.

What are AI credits?

Each paid plan includes a monthly pool. Credits are drawn by what the model actually reads and writes on each run, so there's no flat price per question — a short question costs less than a long workflow — and every call is listed with what it used on the AI activity page. Asking Erina a question, the AI steps inside Do something and the four workflows, and the handful of agents that read with a model draw from it. The Simple pages — Home, My money, Stocks — spend nothing: every number there is deterministic. Neither do imports, ticker lookups, charts, calendars or Today's queue.

Start your trial

Show Erina what you own. She'll tell you what needs a decision.

About a minute, no card, no broker login. A first read in seconds, a plain-English answer every morning after that.
