Your AI builds the model. You own the odds.
extic turns filings into a probabilistic valuation of every company you own or watch: what's priced in, what could happen, and what would change your mind.
Runs in the Claude or ChatGPT plan you already have. Exploring needs no sign-up.
The price needs the guided AI build-out and retained pricing power.
From a 10-Q to the odds behind your position, in one conversation.
Ask Claude or ChatGPT to value a company. It pulls the 10-Q, the call and whatever else it needs, and builds a workbook in which every number points back to where it came from.

A tested engine values every combination of the stories you set odds on. You get a distribution, not one answer.
Point at what you disagree with, see what the price assumes, and write down what would change your mind. After earnings, one conversation brings it up to date.

Disagree with a number? Point at it and say so.
Click a number, a story or a paragraph on a workbook or an industry, and speak or type. Your AI knows exactly what you pointed at. Tell it to address your annotations, and it changes the workbook, or tells you why not, and replies with what changed.

For investors who do the work themselves.
Twelve holdings. One weekend after earnings. No analyst.
Every company you own gets a model that stays current, with odds instead of one number and a record of why you bought it.
Investor planYou build models all day. Your own portfolio gets a spreadsheet from 2019.
A desk-grade model of every holding, with its cost of capital, business lines and claims, that exports to Excel with every cell a formula.
Three partners. One view of the AI build-out.
Set the odds on a shared story once, and every holding it touches moves with them. Roles, and a written rule on who at extic can see your work.
A valuation you can question, because it's yours.
Someone else's fair value can't be questioned, and a spreadsheet gets rebuilt only when there's time. extic's valuations are sourced to filings, tested, and kept current.
Every story has a probability you set.
The page shows what each outcome does to the value, and which stories barely matter.
The return the price implies over your horizon.
Bought at 214.13, NVIDIA's median future returns 12.6% a year over 5 years, just under its 12.7% cost of capital.
A tested engine does the arithmetic, not the AI.
Every input cites its filing. Any scenario exports to an Excel workbook whose formulas reproduce the value.
One conversation brings a workbook up to date.
History shows what changed, when, and why, in your own words.
"If the build-out falls short" moves all your chips together.
Industries link one factor across workbooks, at one set of odds.
| Median | boom | guided | short | bust | price |
|---|---|---|---|---|---|
| NVIDIA | 332 | 232 | 140 | 73 | 214 |
| Broadcom | 573 | 388 | 216 | 131 | 329 |
| AMD | 349 | 274 | 200 | 127 | 529 |
