Sign up for Corsac — set up your eval workspace
What happens after you sign up
01
We read your submission
A person — not a queue — reads what you're building and which workflows you need evaluated. You'll hear back by email, typically within a business day.
02
Your workspace gets set up
We provision your workspace with the eval packs that match your product from the published library, plus any custom areas your submission calls for.
03
You run graded evals
Scenario-based evals graded case by case by an LLM judge against expected-behavior rubrics — with managed expert review available where human judgment is the bar.
Not ready to sign up? Try the benchmark generator anonymously, browse the eval library, or read what opinionated evals are.

Start with the Eval Library.
Skim our library of packs across support, claims, clinical, and ops. If one already fits, that is the cleanest path in.
