Cursor develops 'Sand', a general AI agent to take on Anthropic's Claude Cowork

Transparency notice: the original article from The Information on this topic is largely blocked behind a paywall. The downloaded content only includes the headline, the site navigation and an unrelated context line ("Before Apple Lawsuit, a Growing Unease at iPhone Maker Over OpenAI"), without the actual body of the story. For this reason, the analysis that follows is not based on that text, but on publicly documented information corroborated by several independent outlets (including summaries from The Information itself, PYMNTS, TweakTown and others) that covered the same scoop.

According to those sources, Cursor —the startup behind the popular AI-assisted code editor— is said to be internally developing a general-purpose agent. Unlike its earlier products, focused on programming, this agent would be intended for non-technical users: it would act as a personal assistant capable of answering emails and messages, organizing spreadsheets and carrying out everyday administrative tasks, that is, general office work and not just engineering tasks.

The project's exact timeline and its commercial launch plans are not confirmed by the company, and the available sources do not detail these aspects with certainty. Any specific timeframe for the start of development, internal deployment or market release should be considered preliminary and unverified.

The move is understood as a direct response to Claude Cowork, Anthropic's agent that brings the agentic capabilities of Claude Code (its tool for programmers) to general office work, without the need for a terminal. Cowork allows skills, connectors and subagents to be combined so that Claude acts as a specialist for a specific role, team or company, executing complex multi-step tasks autonomously while the user is in a meeting, on their phone or offline. Anthropic recently expanded its availability to mobile and web, following a more limited beta phase. According to the coverage, software development would represent a minority share of Cowork sessions, while business operations and content creation —expense reconciliation, contract review, client presentations— would account for a substantial portion of usage, although no exact verifiable figures are provided. The tool can only read and write in folders explicitly connected by the user, respects network access settings and requires approval for sensitive actions such as deleting files.

Taken together, the episode illustrates how competition among AI agents, which began in the field of coding (Cursor, Claude Code, GitHub Copilot and the like), is now shifting to office work as a whole, with Anthropic and potentially OpenAI as direct rivals to Cursor in that new arena. The specific details of timelines, code names and product scope should be treated as preliminary information subject to change, given that they come from reports not yet officially confirmed by the companies involved.
