Enterprise AI and plagiarism detection for content integrity
Identifies AI-generated text across 30+ languages and leading LLMs, with reported accuracy above 99% on internal English test sets.
Searches 60 trillion websites, 16,000+ open-access journals and internal repositories to catch paraphrasing and hidden copying.
Extends detection to AI-generated video, audio and images so teams can verify content beyond text alone.
A scalable API and workflow integrations automate content analysis inside LMS platforms, publishing tools and enterprise systems.

Find and fix problems in your AI agents before users do
See every message, tool call and decision in a run, with inputs, outputs and durations, so you can pinpoint where a run broke down.
Recurring failures are grouped into issues with severity, affected users, last-seen time and a confidence score, instead of scattered alerts.
An agent investigates issues and automates follow-up across Slack, the web app and MCP, so debugging happens where your team already works.
Run scenarios against a change on a pull request and compare results with real traffic to catch regressions before merge.
