Stop guessing. Start knowing.

Every week without automated optimization is another week shipping regressions you don't catch.

What an ML engineer costs to manually review prompts 20 hrs/week
7 of 8
Prompt changes degrade performance. Without regression testing, you ship most of them.

Spectral does it continuously, autonomously, with holdout validation on every change.

Not just prompt tuning. Spectral diagnoses across 6 scales — model config, output format, agent topology, tools, context management. If the problem isn't in the prompts, we'll tell you what it actually is.

Frequently asked questions

Growth gives you continuous scanning on up to 3 workflows. Production unlocks unlimited workflows, cross-workflow intelligence (fixes from one pipeline accelerate the next), dedicated Slack support, and early adopter pricing locked in before Q3 2026. Most design partners start at Production.

You get a full report: failure clusters, root cause attribution, what's fixable via prompts vs. what's a data/infrastructure problem. No credit card. If the results show failure patterns your team didn't know about, we'll talk about the optimization loop. If they don't, you lost 5 minutes.

Growth and Production are flat-rate. No per-seat pricing, no per-trace pricing. If you need 10+ workflows, SSO, or a BAA for healthcare, contact us for Enterprise pricing.

Prompts are encrypted in transit (TLS) and at rest (AES-256). We never train on customer data or share it with third parties. Scan results are retained for 90 days, then permanently deleted. See our Privacy Policy.

Spectral tells you. Every failure cluster is tagged with a source: prompt deficiency, retrieval quality, input data, or infrastructure. If the bottleneck is your RAG pipeline, Spectral says so instead of wasting scans on prompt changes. That diagnosis alone saves weeks.

Yes. Every scan generates a shareable report URL you can send to your VP Eng, your team, or your stakeholders. Read-only, tokenized — no login required to view.
