All-in-one AI assistant across web, browser, desktop and mobile
Chat with a rotating roster of leading LLMs from OpenAI, Anthropic, Google and others, switching models per task without separate subscriptions.
Works on Chrome and Edge to summarize pages and YouTube videos, explain or translate selected text, and assist with writing directly inside any web page.
Rewrite, humanize or generate text, get full-page bilingual translation, and chat with or translate PDF documents.
Create images, convert image-to-image, animate stills, remove backgrounds or watermarks, and generate logos and avatars.
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.
