The AI coding agent for building ambitious software
An agentic mode that plans changes, edits several files at once, runs tests, and iterates until the task is complete.
Background agents spin up their own environments to build, test, and demo features in parallel, then hand back results for review.
Fast inline suggestions plus codebase-wide semantic search and indexing so answers reflect your actual repository.
Switch between leading frontier models from multiple providers, or let Cursor select a model automatically for each task.
AI sidebar and browser agent for reading, writing and research
A persistent panel that reads the page you are on and answers follow-ups with GPT, Claude or Gemini without copying content into another tab.
Summarise long articles, PDFs and YouTube videos, extract key points, and ask detailed questions about the source material.
Translate webpages, PDFs and images, compare bilingual output side by side, and have content read aloud for review on the move.
Delegate multi-step tasks across real websites — price comparison, form filling, research and inbox triage — using your existing logged-in sessions.

SpecialistOpenAI's flagship multimodal assistant powered by GPT-6 and GPT-5.6 for reasoning, coding, and deep research.

SpecialistAnthropic's frontier AI workspace powered by Claude 5.5 for agentic coding, analysis, and nuanced writing.
Provides powerful parallel AI coding agents via a desktop command center, but is less integrated into a traditional editor.
#3
SpecialistEnables instant cloud-based full-stack app building from natural language, but is less suited for local offline repositories.

Free / Open-sourceOffers unmatched extension support and official Copilot integration, but lacks Cursor's out-of-the-box deep codebase indexing and agentic editing.

Features advanced multi-file planning and codebase reading, but lacks Cursor's smooth chat-to-edit inline workflows.

Offers a very similar browser sidebar experience with multiple AI models, but features slightly different pricing and workspace tools.
Focuses on spec-driven engineering and structured agent planning, but offers less fluid ad-hoc inline code generation than Cursor.
SpecialistOperates as a fully autonomous software engineer for complex tasks, but lacks the snappy interactive inline editing of Cursor.

Free / Open-sourceThe coding agent that learns your coding taste
Provides robust browser-based summarization and prompt assistance, but lacks some of Sider's deeply integrated multi-model chat UI features.
Delivers a polished AI-native IDE experience with multi-file generation, but has a smaller ecosystem than Cursor.
