AI governance, testing, and observability for regulated enterprises
Dozens of pre-built evaluations cover quality, safety, security, and performance, with LLM-as-a-judge scorers, session-level metrics, and support for writing your own custom tests against your own data.
Import a repository and run evaluation suites automatically on every change, benchmark each iteration, and block releases when a metric regresses beyond the threshold you define.
Trace every request through multi-step agent workflows, including tool calls and retriever steps, with token counts, latency, cost per request, alerting integrations, and subpopulation analysis.
Register each AI system with an owner, purpose, data sensitivity, and risk tier, score inherent risk across multiple dimensions, and move systems through staged approval gates before they reach production.
Humanize AI text and check how human it reads
Rewrites AI-generated drafts with natural phrasing, rhythm and flow, and lets you pick light, medium or aggressive rewriting depending on how much change you want.
Scan text before and after humanizing to see which sentences still look machine-written, with colour-coded sentence-by-sentence highlights.
Click any sentence to see alternative rewrite options and fine-tune the output until it matches your own voice.
Returns humanized text in seconds, with word limits per input ranging from 1,000 words on the free plan up to 5,000 words on paid tiers.
