Just Smarter Eval

Benchmark, govern, and ship LLMs — on EU infrastructure.

Product datasheet
v2026-04-24

The evaluation and governance layer for regulated AI teams. Compare 37+ frontier LLMs on your own data, produce compliance-grade audit trails, and run the entire workflow inside the EU. Purpose-built for AI platform leads, governance teams, and CISOs who can't deploy LLMs on vibes.

What it does

Benchmark

Upload a dataset. Fan out across every model in the Brain Orchestra catalog (30+ today, growing as BO adds them). Get a scorecard — latency, token count, credits, quality — sortable by any column. Export to PDF / CSV / JSON.

Judge

LLM-as-judge scoring with configurable rubric. Claude Opus is the default judge; swap for domain-specific grounding. Per-row quality score per model.

Govern

Every eval run produces an admissible audit artifact: dataset hash, model versions, hosting tier, per-row I/O, timestamps, EU-region attestation. Covers AI Act Art. 15 accuracy-logging requirements.

Ship

Save suites. Detect prompt regressions before deploy. Compare model upgrades objectively. Wire into CI/CD via REST API. Prompt changes caught in dev, not by customers.

Why enterprises pick Just Smarter Eval over US-hosted alternatives

EU-native by design — Xalerate AB, Sweden. No US parent, no CLOUD Act reach. EU Strict tier keeps data with EU-owned vendors only.
Multi-model bake-off as the primary workflow, not a buried playground feature. Competitors treat it as a side panel.
Council / Superpower synthesis — novel ground-truth primitive using ensemble + web-grounded fact-check. No competitor offers this.
Compliance artifacts per eval run — AI Act Art. 15, GDPR Art. 28 DPA, SCCs, sub-processor transparency. See justsmarter.ai/trust.
UI-first — non-engineer AI platform leads can run evals themselves. No Python, no API-only workflow.

Try it now: The runner is live at justsmarter.ai/eval — paste prompts, pick models, run. Or book a 30-minute demo — you leave with a sample eval report on your own data and a clear pilot proposal. Email support@justsmarter.ai.
