You already know the questions.

Should I trim this winner or collar it? What is this print actually pricing? Where does this cash go? Erina answers the questions you're already asking — using your real positions, and showing every step of the reasoning.

01

Nothing to set up

Four sample books ship with the product. Every workspace is populated the second you land — no CSV, no broker link, no empty state.

02

Nothing hidden

Every recommendation carries the prose behind it — what moved, what re-rated, what the trade-off is. If you disagree with the reasoning, you can see exactly where.

03

Nothing runs itself

Erina isn't connected to a broker and can't execute. Every workflow ends in options you choose between. The order is always yours to place.

Six workspaces

One workspace per decision — not a dashboard of charts.

Every workspace opens on live numbers from your book, then hands you a workflow that reasons through the specific decision in front of you. The numbers below are from the sample portfolio you'll land on.

Anatomy of a recommendation

Every answer has the same four parts.

This is a real output from the Book & Protect workspace, running on the sample book. Position, reasoning, options, your call — in that order, every time.

workflows / book-protect · balanced growth Sample book

Should I book, protect, or add?

Positions up 20% or more. Erina explains the reasoning behind each option.

5 winners found.
Your position META 60 sh @ $400.00 now $578.40 +$10,704 (+44.6%)
The reasoning, always shown
Erina's read

META is your biggest winner — up 44.6% and now the second-largest position in this book. The run is being carried by ad-price growth and Reels monetization, both structural rather than one-quarter tailwinds. That said, at $578 the stock has re-rated to ~26× forward earnings, its widest multiple in three years, and the position is now ~2.8× your average non-mega-cap allocation.

The question isn't whether the story is intact — it is — but whether the position size still reflects your original conviction. If you'd started fresh today, would you buy 60 shares at $578? Most books say no.

You pick — nothing auto-executes
Options
Trim 25% (sell 15 shares)

Books gains, keeps 45 shares of exposure, and re-anchors position size closer to your average.

Realized +$2,676 45 sh left
Costless collar (60d)

Sell a Sep $620 call, buy a Sep $540 put. Downside defined, no shares sold, position keeps compounding.

Floor $540 Cap $620 Cost ~$0
Hold — thesis intact

Revenue and margin rate-of-change still improving. Cutting on multiple alone leaves money on the table.

No P&L impact Revisit at earnings
Position

Your actual size, cost basis and mark — pulled from the book, not a generic example.

Erina's read

What drove the move, whether the multiple re-rated, and how the position now sits against the rest of your book.

Options

Two or three concrete structures with realized P&L, floor, cap and cost attached — including holding.

Your call

Choosing one saves it as a tracked recommendation. Erina never places the order.

From signup to first answer

Judge the reasoning before you hand over your book.

Most finance tools make you do the data entry first and find out whether they're any good afterwards. Erina inverts that. You get a fully populated book on arrival, and four of them to switch between — so you can stress-test the reasoning on a portfolio that isn't yours.

  • Sign up with email or Google. No card. A 30-day trial with the full Solo feature set starts immediately.
  • Land on a live sample book. $524k across ten-plus positions, with winners, laggards and cash already in place.
  • Run any workspace. Book & Protect, Earnings Prep, Deploy Cash — all six work on the sample from minute one.
  • Add your own when convinced. Screenshot your broker app and drop the image in — Vision reads it. Importing never spends credits during the trial.

Balanced Growth Default

A $524k core book — mega-cap tech, a few laggards, $25k in cash waiting.

Income Overlay

Built for premium selling: covered-call candidates and CSP targets throughout.

Concentrated Winners

A handful of positions that ran hard. Concentration and trim decisions everywhere.

Options-Heavy Hedged

Spreads, collars and long puts layered on stock — the Greeks actually matter here.

Your own book

Screenshot your broker. That's the import.

The step that kills most portfolio tools is data entry. Erina's fastest path needs nothing but your phone: screenshot your holdings, drop the image in, and Claude Vision reads the tickers, share counts and cost basis straight off it.

Screenshot Fastest

Screenshot your broker app and drop it in.

Claude Vision reads the tickers, share counts and cost basis straight off the image. Works with a screenshot from any broker's mobile or web app — nothing to export, no file format to get right, no API to connect. Max 4MB.

Paste

Copy the rows out of your broker and paste.

Select your positions table, paste the text, and Erina parses it into rows. Useful when you're already on a desktop and copying is quicker than screenshotting.

CSV

Upload the export your broker already gives you.

The standard positions export from any broker. Best when you want exact cost basis and lot detail carried across without review.

By hand

Add rows manually.

For a handful of positions, or to add a name to a book you've already imported. Also how you log a trade after the fact.

Importing is free. Screenshot and paste imports are the only two things in the product exempt from the credit gate during your trial — deliberately, so credits go to analysis rather than data entry.

Why not just ask a chatbot

A general chatbot doesn't know what you own.

You can ask any model whether META looks expensive. What it can't tell you is whether your META position is now 2.8× your average allocation, or that you're carrying $4.6k of harvestable losses two rows down.

Common questions

The things people ask first.

What do I get on the free trial, and do I need a card?

No card. Every new account starts on a 30-day trial with the Solo surfaces unlocked — all six workspaces, portfolio import, watchlists and Ask Erina. Importing your book is free during the trial, and the deterministic readouts on your own positions (value, concentration, winners past 20%, harvestable losses, the earnings queue) cost nothing to run. The AI credits that power the LLM workflows come with a paid plan — until you activate one, you explore those workflows on the sample books. When the trial ends the account falls back to Free rather than locking you out, and your data stays put.

Do I have to enter my portfolio before I can see anything?

No. Four sample books ship with the product — Balanced Growth, Income Overlay, Concentrated Winners, and Options-Heavy Hedged — and you can switch between them from the header. Every workspace is fully populated the second you land, so you can judge the reasoning before you trust it with your own positions.

Does Erina place trades?

No. Erina is not connected to a broker and cannot execute anything. Every workflow ends in options you choose between, 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 plan includes a monthly pool. Erina chat answers, generated research, and workflow runs draw from it, and each run shows what it will cost before you press it. Ticker lookups, charts, cached research, and the deterministic detectors on your dashboard spend nothing at all.
