Free browser AI humanizer that rewrites AI text to read naturally
Paste AI-generated text, complete the captcha, and get a reworded, more natural-sounding version back in a single step.
You can use the humanizer directly in the browser without registering, signing in, or installing anything.
The rewrite is designed to retain the original meaning and SEO terms so you do not lose search relevance.
Alongside the humanizer, the site offers paraphrasing, plagiarism checking, grammar checking, and AI detector tools.
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.
