You always know what a run costs.

Every plan includes a monthly credit pool. The expensive work — Erina chat answers, generated research, workflow runs — draws from it, and each run shows what it will spend before you press it. There is no metered surprise at the end of the month.

  • Free of credits: ticker lookups, charts, fundamentals, cached research, and every deterministic detector on your dashboard.
  • Spends credits: generated research reports, Ask Erina answers, and the LLM workflow runs inside each workspace.
  • Exempt during trial: portfolio imports, so getting your book in never costs you analysis.

Which one

Pick by what you're trying to do.

Free

You want to look things up and read research. You're not ready to put a portfolio in.

Solo

You have a book and want the six workspaces reasoning over it. This is the plan the trial gives you.

Pro

You trade options and want flow anomalies, strike selection and multi-leg construction alongside the workspaces.

Power

You model before you trade. Backtesting rules per ticker and scanning the market for the setups they define.

Research & watchlist is free forever. Solo and above unlock all six workspaces on your own positions — and the 30-day trial gives you Solo without a card.

Billing questions

Before you pick.

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.

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.

Is this investment advice?

No. Erina generates research and structures trades from public data. Nothing on the platform is personalized investment advice, and we are not a registered investment adviser. Every AI output carries that disclaimer inline — the risk disclosures cover the detail.

Does importing my portfolio cost credits?

No. Screenshot and paste imports are explicitly exempt from the credit gate while you're on the trial — they're the only two things in the product that are. Getting your book in is deliberately free, so credits you later buy go to analysis rather than data entry.

Can I switch or cancel plans?

Yes, both from the Account page via the Stripe customer portal. Upgrades apply immediately with proration; downgrades take effect at the end of the cycle you already paid for. Cancelling drops you to Free at period end and keeps your data.

The trial answers the question pricing can't.

Thirty days of the full Solo feature set, on a book that's already loaded. Decide after you've read the reasoning, not before.
