Cursor is an AI-native code editor built as a fork of VS Code, designed from the ground up for AI-assisted development. It features intelligent code completion, multi-file editing, codebase-aware chat, and an agent mode that can autonomously plan and execute coding tasks. Cursor uses a combination of its own models and frontier LLMs (Claude, GPT-4) to provide the most context-aware coding assistance available. It has become the editor of choice for many AI-first developers.
Tabnine is an AI code assistant focused on privacy and enterprise compliance. It offers code completions, chat, and code generation while keeping code private—models can run entirely on-premises or in a private cloud. Tabnine supports all major IDEs and programming languages, and differentiates with its zero data retention policy and SOC 2 Type II compliance, making it the go-to choice for regulated industries.
