Features

What you get is a reviewable valuation discipline

Not "stocks that will go up," but an institutional-grade, source-bound, auditable valuation process—and a content asset you own.

Two output tiers, used as needed

Snapshot Card (Free)

Understand in 30 seconds whether a stock is cheap or expensive right now: valuation state, action label, Required Return, probability-weighted IRR, Return Spread, dynamic entry range (Forward P/E), and a one-line conclusion — all on a single page. Free.

Institutional Locked Card (Subscription)

A complete audit trail, like an investment committee: source ledger, key-debate table, sensitivity variables, scenario engine, terminal-multiple anchoring, DCF/FCF cross-validation, Locked Card draft, and Decision Journal. Sources are traceable, assumptions are locked, and the output is refreshable and reviewable — item by item — and saved as a Locked Card you own. Unlocked with a subscription.

Three operating modes covering your full workflow

New Valuation

Run a complete formal valuation on a new stock, establishing the Locked Card (v1) and Decision Journal.

Data Refresh

With an existing card, recompute the current conclusion against new price and fundamentals — without changing long-term assumptions.

Revision

When evidence shows that long-term assumptions have changed, the engine alerts you and enters revision in one click, generating a new card version (v2/v3…).

Second Core · The Asset You Own

The Locked Card: turning a single valuation into an investment you can hold

The engine gives you "one correct judgment"; the Locked Card gives you "long-term discipline and a reviewable asset." A valuation is a single moment; an investment is an entire journey — and it is the latter that truly determines your return.

Lock assumptions, prevent drift

Freeze your Required Return, terminal assumptions, and Kill conditions. When prices swing, let your calm self hold your anxious self in check.

Review to improve

A built-in Decision Journal records your thesis, data, and timing. Review honestly afterward to distinguish luck from skill.

Low-effort maintenance

New data only needs a "refresh," leaving long-term assumptions untouched; revise only when evidence truly changes — with a full, auditable trail throughout.

It is your asset

Stored in your own account / GitHub, building year over year into a research-card library that is yours — the platform cannot take it.

Why You Need a Locked Card →

The institutional-grade discipline behind it all

Source-bound and auditable

Every key figure is bound to its source, definition, and timestamp; vague "public data" is not accepted.

Anti-hallucination

No fabricated prices, EPS, news, consensus, or terminal multiples; if a figure cannot be found, it is flagged "missing" and confidence is lowered.

Formal vs Provisional

Only complete, gate-passing data qualifies as Formal; otherwise it is clearly labeled Provisional, never dressed up.

Interchangeable models

The architecture supports five major model providers, with stronger models available on paid tiers to ensure faithful rule execution.
