Grammarly is Superhuman, Cursor 2.0 & more (October 30, 2025)

Good morning,

From new AI legislation to major product overhauls, today’s stories show how fast the ecosystem is evolving. Cursor debuts its agentic Composer model, Extropic claims a sustainable chip breakthrough, and Grammarly rebrands as Superhuman to challenge the next era of writing tools. The AI landscape is rewriting itself in real time.

Let's dig in👇

💰 Money Moves

💰 Overhaul follows bipartisan GUARD Act to block minors from AI companions

A new bipartisan bill would penalize companies that let minors access AI companion tools without safeguards. Lawmakers argue the fines, up to $100,000, are necessary to push accountability for mental health and privacy concerns. If passed, it could mark the first major U.S. law directly regulating emotionally interactive AI systems.

📰 Cursor 2.0 introduces Composer, Cursor’s new agentic model

Cursor has launched its Composer model, an agentic system built for rapid, collaborative coding. The release promises up to 3x faster iteration speed by linking model reasoning to user codebases in real time. It signals the next evolution of AI coding platforms toward multi-agent orchestration rather than simple autocomplete.

⚙️ Extropic claims AI energy breakthrough with thermodynamic chip

Extropic unveiled a new chip architecture that mimics thermodynamic processes to drastically reduce AI energy consumption. The company says its prototype operates at near-zero cooling costs while maintaining top-tier inference speeds. If validated, it could redefine data center efficiency and reshape the economics of large-scale AI training.

🚀 New Launches

💡 Agent HQ is GitHub’s new mission control for AI agents

GitHub has introduced Agent HQ, a dashboard for managing multi-agent AI systems. It enables developers to assign roles, monitor collaboration, and integrate external APIs into coordinated workflows. With the rise of composable agentic systems, GitHub aims to become the “mission control” center for enterprise AI development.

✍️ Grammarly rebrands to Superhuman with AI writing assistant

Grammarly has rebranded to Superhuman, unveiling a faster, context-aware AI assistant for writing and communication. The redesign integrates predictive tone adjustment and task-based drafting across email, chat, and documents. The move positions Superhuman as a direct rival to Notion AI and Microsoft Copilot in everyday productivity workflows.

📢 Pomelli is Google Labs’ new experiment for on-brand AI content

Google Labs has unveiled Pomelli, an internal AI experiment for automating brand-consistent creative content. The tool helps marketing teams produce assets that adhere to visual identity guidelines and voice tone. If it scales, Pomelli could redefine how agencies standardize creativity across massive digital campaigns.
