Detailed Review
Cursor was founded by four close friends from MIT in 2022, after OpenAI released the GPT-3 API and they clearly saw the potential for AI-powered coding. They forked VS Code — a bold but smart move: inheriting the entire extension ecosystem and a familiar UI, while focusing purely on the AI layer. Anysphere — Cursor's parent company — received investment from the OpenAI Fund from the very beginning.
Cursor set a new standard for AI coding with three differentiated features: Tab completion that's smarter than Copilot because it uses a custom model trained specifically for code completion; Composer/Chat with full codebase context — the AI understands the entire project, not just the open file; and Agent mode that autonomously runs multi-step tasks, like a junior developer pair-programming with you.
Cursor Rules is a lesser-talked-about but extremely powerful feature: a .cursorrules file in the project folder contains instructions for the AI about coding conventions, architecture patterns, and business logic specific to that codebase. Every team can customize Cursor so the AI "understands" their project more deeply. This is "software documentation as AI instructions" — a trend that's changing how teams write software.
Current Developments (2025–2026)
Cursor Agent 2.0 with the ability to autonomously run tests, read errors, fix them, and iterate — without manual intervention — is under development. Background agent lets Cursor continue a task while you work on something else. Cursor generates an estimated $40,000 ARR per engineer at companies using it — the highest ROI in developer tools. A $900 million Series B values Cursor at $9.9 billion — the largest unicorn in developer tools history.
Strengths
- Tab completion predicts entire multi-line code blocks, editing simultaneously — noticeably faster than Copilot
- Composer lets you describe a feature in plain language and AI writes the code from A to Z
- Agent mode runs the terminal, reads errors, and fixes them in sequence — like a junior dev working alongside you
- Understands your entire codebase context, suggesting code that matches your project's patterns and conventions
Areas for Improvement
- Pro plan at $20/month is needed to fully use GPT-4o; the Free tier severely limits fast requests
- RAM consumption is 20–30% higher than stock VS Code — noticeable on 8GB RAM machines
- Agent occasionally modifies code outside the requested scope — always review the diff carefully before accepting
Verdict
Cursor is an excellent choice for anyone needing a powerful tool in the PC Software category. Founded in 2022 by Michael Truell (CEO), Sualeh Asif, Arvid Lunnemark, Aman Sanger — all four from MIT, this product has undergone years of development and continuous improvement. With a rating of 9.6/10, it ranks among the best in its segment. We encourage you to try the free version before deciding to upgrade.
