Anthropic's frontier AI workspace powered by Claude 5.5 for agentic coding, analysis, and nuanced writing.
Combines frontier Claude Opus 5.5 and high-speed Sonnet 5.5 with configurable extended thinking, up to 1M-token context windows, and 128K-token outputs.
Pro, Max, and Team Premium plans bundle Claude Code for autonomous command-line software engineering, test execution, and repository-wide refactoring.
Renders live interactive web apps, visualizations, spreadsheets, and formatted PowerPoint decks in a dedicated workspace panel alongside the chat.
Grounds conversations in shared project knowledge bases and connects directly to local filesystems, GitHub, Slack, and internal databases via MCP.

Check in seconds whether a passage was written by a human or an AI
The detector returns an assessment of how much of a submitted passage reads as AI-generated, based on a model trained on a very large mixed corpus of human and machine text.
Runs complete in seconds so you can screen drafts, student essays or client copy during your normal editing pass.
Each submission handles roughly 2,000 characters at once, enough for an abstract, an email, a product description or an article excerpt.
The detector is built for anyone who needs a quick authenticity read rather than a forensic report, with no complex setup or account requirements.
