Business-specific, not generic
Scored against your product's standard, your domain rules, and your workflow — so you can trust a pass, not take a generic “looks reasonable” on faith.
Evaluation Builder
Turn expert judgment into a reusable evaluator
Argmin AI captures expert corrections on selected cases and turns their judgment into a calibrated evaluator your team can run on every AI change.
First evaluator free · No card · Your data stays private
Make expert review reusable instead of repeating it every release.
Your expert re-reviews the same kinds of outputs every release, and their judgment lives in their head, not in a test.
Why generic judges fail
Generic LLM judges pass the wrong things
A generic judge can tell you an answer sounds reasonable.
It cannot know your task, policies, edge cases, or expert standard until it is calibrated.

Where trust comes from
A judge grounded in your business and your experts
Built on your experts' vision
Your experts' corrections become the rubric and the labels — it reuses their judgment, it doesn't replace them — so the judge scores the way your team would.
No golden dataset upfront
It cold-starts the judge and a calibrated test set from your traces, plus synthetic and adversarial cases.
Explained, not a black box
Criterion-level scores with a reason for every pass or fail, so you see what broke and why.
A release gate that lasts
Versioned rubric and history; rerun it on every prompt, model, RAG, or agent change.
Outcome
What you get
Evaluator · calibrated
An evaluation system, calibrated
Rubrics, edge cases, and judges tuned to your domain and aligned with your experts. Ready to run on every model, prompt, or agent change so you see what improved and what broke.
Dataset · aligned
A calibrated test set
A lightweight, labeled set built during calibration. You confirm, override, or drop the labels, so it reflects your team's judgment, not the model's. Enough to start testing the AI agent you are building.
Process
How it works
A calibration flow for teams that do not have a clean golden dataset yet.
InputsBring task, docs, traces, and hypotheses
Start with the AI task, domain docs, selected traces, and a few hypotheses about what good looks like. No golden dataset is required upfront.
CasesArgmin AI picks cases and analyzes evaluator mistakes
The platform finds normal, edge, and high-risk examples and surfaces where the evaluator disagrees with experts, so review time is spent on cases that actually move agreement.
ReviewExperts review, confirm or correct calls
Experts review and correct evaluator calls Argmin AI drafts first, never from a blank page.
CalibrateCorrections improve the evaluator and become the eval set
Every correction sharpens the evaluator and updates the calibrated eval set, quality rubric, score anchors, and calibration history.
RunTest every AI change
Use the evaluator on prompt edits, model switches, RAG updates, routing changes, and agent releases.

Internal Case Study: Mental Health Conversational AI
Main challenge: Preserve sensitive quality dimensions while making changes
Results
- Experts reviewed evaluator behavior
- Rubrics captured sensitive quality dimensions
- Edge cases stress-tested the evaluator
- Corrections became reusable calibration history
The expert position
Domain experts should set the bar, not manually re-score every candidate release. Calibration makes their corrections reusable.

Expert review reused
Watch expert review become an evaluator
See how expert corrections become reusable evaluator behavior, not one-off review notes.
Key benefits & features
Expert-Calibrated
Experts confirm or correct evaluator calls on selected cases, so the evaluator learns the team's standard.
Rubric With Anchors
Judgment becomes a quality rubric with score anchors and examples, not a vague prompt.
Correction History
Every correction is retained, versioned, and available for future calibration rounds.
Reusable Review
The same expert signal runs against future AI changes without asking experts to repeat the same work.

FAQ
No. Existing labels help, but they are not a precondition. Argmin AI starts from your task, domain docs, selected traces, and expert corrections during calibration.
Usually selected traces, representative outputs, product constraints, and domain docs. You decide what is shared. We can work under NDA and with tighter infrastructure constraints when needed.
No. Synthetic cases can expand coverage, but the calibration anchor should come from your real traces and your experts' corrections.
No. The evaluator drafts calls first, Argmin AI picks the cases that matter, and experts confirm or correct. Labeling becomes review, not a blank-page grind.
A calibrated eval set, quality rubric, runnable evaluator, core regression cases, and calibration history your team can reuse across AI changes.
Yes. The evaluator creates the quality bar first. After that, Argmin AI can optimize prompts, models, routing, retrieval, and agent architecture without flying blind.
