What Cursor Does
Cursor is what happens when a team of MIT graduates — Michael Truell, Sualeh Asif, Arvid Lunnemark, and Aman Sanger, who incubated the project through OpenAI's accelerator program — decides that AI should not be bolted onto an editor as an afterthought. It should be the editor. Built by Anysphere as a fork of Visual Studio Code, Cursor preserves the familiarity that millions of developers have with VS Code while fundamentally rethinking how AI participates in the act of writing software. The result is an IDE that does not just suggest the next line of code. It understands your entire codebase, reasons across multiple files, and can execute complex refactoring tasks that would take a human developer hours to complete manually.
Migration and Composer
The migration story is one of Cursor's strongest selling points. Because it is a VS Code fork, every extension, keybinding, theme, and workspace setting transfers over without friction. Developers report completing the switch in under ten minutes. This is not a tool that asks you to abandon your muscle memory. It is one that builds on top of it. For teams already invested in the VS Code ecosystem, the switching cost is effectively zero — which is exactly why adoption has been so rapid across the industry.
The standout feature is Composer — Cursor's multi-file AI editing engine. Unlike traditional inline completions that operate on a single file, Composer reasons about relationships between files. Ask it to add authentication to your application, and it will modify your routes, create middleware, update your database schema, and adjust your frontend components in a single operation. The diff-based workflow gives you full control: every change is presented as a reviewable diff that you can accept, reject, or modify before it touches your codebase. This prompt-review-commit rhythm feels natural and is what separates Cursor from simpler autocomplete tools.
Tab Completion and Background Agents
Tab completion in Cursor deserves special mention. The proprietary model powering it achieves significantly higher acceptance rates than competing solutions. The cursor-jump feature — which predicts where you will edit next and positions your cursor there — is uncanny in its accuracy. After using Cursor's tab completions for a week, many developers report that going back to standard GitHub Copilot completions feels noticeably slower. The predictions are contextually aware, drawing on your entire project rather than just the current file.
Background agents represent Cursor's most forward-looking feature. You can launch AI coding tasks that run autonomously while you continue working on other files — essentially having a junior developer working in parallel on delegated tasks. Combined with BugBot for automated bug detection and the ability to spawn specialized subagents for testing, documentation, or refactoring, Cursor is pushing toward a future where the developer's role shifts from writing every line to reviewing and directing AI-generated work.
Inline Editing and Pricing
The inline editing workflow via Cmd+K is where most developers spend their time. Highlight a block of code, describe what you want changed, and Cursor shows you the diff. Converting callback patterns to async/await, adding error handling, extracting functions, translating between frameworks — these are all single-prompt operations. For frontend development with React, CSS, and modern JavaScript frameworks, the experience is exceptional. Backend development with languages like Java and Spring Boot is competent but not as polished, where specialized IDEs like IntelliJ still hold an edge in deep ecosystem understanding.
Pricing has been a point of contention. In mid-2025, Cursor shifted from a fixed 500 fast responses per month to a usage-based credit system at the same twenty-dollar price point. This effectively reduced the number of requests for heavy users, and some were caught off guard by overage charges. The CEO issued a public apology, but the episode highlighted a tension that many AI tool companies face: balancing sustainable economics with developer expectations of predictable pricing. The current lineup is Hobby (free) with limited usage, Pro at twenty dollars per month, Pro+ at sixty for developers who lean heavily on Agent mode, Ultra at two hundred for power users who live inside the editor, and Teams at forty dollars per user per month with admin controls.
Interface and Privacy Considerations
The interface can feel cluttered. AI icons, chat panes, diff views, and agent status indicators compete for screen real estate. Developers who value a minimal, zen-like coding environment may find the visual noise distracting. The sheer number of AI features available at any moment can be overwhelming for newcomers, even though the underlying VS Code foundation remains familiar. This is a power tool, and like all power tools, it rewards those who invest time in learning its capabilities rather than expecting instant mastery.
Privacy-conscious developers should note that Cursor requires an internet connection for all AI features. Composer, tab completions, and chat all use cloud-based models. You can edit code offline as you would in standard VS Code, but the AI assistance disappears entirely. There is a privacy mode that prevents your code from being stored on Cursor's servers, but the code still leaves your machine for inference. For teams with strict data residency requirements, this is a meaningful consideration.
Cursor iOS as a Mobile Agent Control Surface
Cursor for iOS adds a phone-native control surface to the same agent workflow described above. Cursor’s official launch page positions the iOS app around building from anywhere: starting cloud agents, remotely controlling agents running on a computer, reviewing artifacts, and moving work forward when an agent needs attention. Fresh launch discussion from Cursor’s official X thread highlights Live Activities and push notifications for agent status, plus the ability to inspect demos, logs, and diffs from the phone. The right buyer interpretation is mobile supervision for asynchronous coding agents, not a full mobile IDE for writing large patches on a small screen.
The PR-review and merge angle is useful but should stay bounded. For small diffs, generated demos, documentation changes, and low-risk agent tasks, reviewing from the phone can shorten the feedback loop between an agent finishing and a human approving the next step. For security-sensitive changes, migrations, infrastructure edits, or large refactors, Cursor iOS should be treated as a triage and monitoring layer rather than the final review surface. Availability and pricing also need attention: the App Store lookup confirms the official Cursor iOS app under Anysphere, while the launch page says the public beta is on paid plans and early X discussion surfaced regional App Store availability complaints. Teams should verify country availability, plan access, and device-management rules before making phone-based agent approval part of their default workflow.
The Bottom Line
Cursor is not a replacement for developer expertise — it is a multiplier of it. The AI occasionally rewrites perfectly fine code because it thinks it knows better, and in multi-stack projects it can mix up frameworks if your prompts are not specific enough. You still need to review every change and maintain architectural discipline. But for developers who are willing to work with the tool rather than expecting it to work for them, Cursor delivers a genuine productivity boost. Fast prototyping, cross-file refactoring, automated commit messages, and intelligent code exploration are all meaningfully better than what existed before. Cursor reports adoption across more than half of the Fortune 500, and a multi-billion-dollar valuation that surpassed twenty-nine billion in late 2025 suggests this is not a tool that will disappear. For better or worse, Cursor represents the future of how software gets written.
