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.
LLM Evaluation Platform
MCP ready*An LLM evaluation platform built around your product
Build eval sets from your real traces, score LLM outputs against your rubric, and compare every change so you catch regressions before they ship.
First evaluator free · No card · Your data stays private
Watch an eval set and evaluator get built from real traces.
You can ship LLM changes fast, but you have no repeatable way to tell if each one made the output better or worse.
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: Build the quality bar before reducing cost
Results
- 9-judge evaluator suite
- 450-item edge-case stress test
- Clinical safety maintained
- 87% cost reduction after quality was measurable
What this proves
The evaluator is not a prompt pasted into a spreadsheet. It is a calibrated quality system built before optimization decisions affect the product.

Key benefits & features
Eval Sets From Real Traces
No golden dataset required. Build the first set during calibration from your traces and expert corrections.
Score Against Your Rubric
Evaluators scored against your product standard, not a generic “looks reasonable”.
Compare Every Change
See what improved and what broke across prompts, models, retrieval, and agents.
Catch Regressions
Keep core cases and rerun them on every release so quality does not slip.

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.
