Built to bring
everyone home.

01Principles
Four promises in every brief.
Not a slogan on a wall. Each one changes what you actually see when you open a plan.

Why this call
- 01
Wind slab on NE aspects is the main hazard; your route stays on SW rock.
Bridger-Teton bulletin - 02
Convection likely after 13:00. Two of five models bring it earlier.
HRRR · ECMWF - 03
Rock reported dry above the Lower Saddle three days ago.
4 trip reports
02Release review
Nothing ships without a rope check.
Every model, prompt or data change that touches a brief passes the same five gates. Any council member can stop a release.

Scenario suite

Briefs that said “not sure”
Saying “not sure” is a feature. When the data is thin, Diorite lowers its confidence instead of guessing.

04Safety council
People who've done the carry-outs.
An independent council of guides, forecasters, rescuers and scientists. Paid for their time, never in equity, and free to block any release.

I joined because I was tired of apps that make every day look like a summit day. My job here is simple: say no until the answer is honest.

The Diorite Charter
Whatever the model, the release or the business plan, Diorite will never:
- I.
Call a route "safe".
Mountains are never safe, only more or less risky. Diorite talks in hazard, exposure and margin.
- II.
Hide uncertainty.
When data is thin or stale, the brief says so in plain words and lowers its confidence.
- III.
Push you to push on.
No timers to beat, no streaks, no leaderboards. Turning around is always a valid outcome.
- IV.
Replace real expertise.
It is not a guide, an avalanche course or a forecast center, and it links back to them.
- V.
Sell where you go.
Your location and trip plans are never sold, and never used to train AI models.
