Copilot vs Cursor Tab

GitHub Copilot and Cursor Tab are both inline code completion tools that predict what you will type next. This comparison focuses specifically on their Tab completion features.

Overview

GitHub Copilot's inline completions predict the next line or block of code as you type. Suggestions appear as ghost text that you accept with Tab. It works in VS Code, JetBrains, Neovim, and Visual Studio. Cursor Tab is Cursor's inline completion feature that goes beyond traditional completions. It predicts not just new code but also edits — it can predict that you want to change existing code based on recent edits and cursor position.

Key Differences

Edit predictions: Cursor Tab's standout feature is predicting edits to existing code. If you change a variable name on one line, it predicts you want to change it on other lines too. Copilot only predicts new code insertions. Multi-line awareness: Cursor Tab predicts multi-line changes across a broader context. Copilot's multi-line completions are improving but tend to be more conservative. Speed: Both are fast, but Cursor Tab uses a custom model optimized for completion speed. Some users report Cursor feeling snappier. Context: Cursor indexes your entire codebase for completion context. Copilot uses open tabs and nearby files. Editor support: Copilot works in VS Code, JetBrains, Neovim, and Visual Studio. Cursor Tab only works in Cursor IDE. Acceptance rate: Developers report higher acceptance rates with Cursor Tab due to its edit prediction capabilities, but this is subjective and project-dependent. Combined features: Cursor Tab is part of Cursor's broader AI feature set (Composer, Chat). Copilot completions work alongside Copilot Chat and PR features.

Pricing

Copilot Individual is $10/month. Cursor Pro is $20/month (includes Tab and all other features).

Verdict

Choose Cursor Tab if you want the most advanced inline completions with edit prediction and are willing to use Cursor IDE. Choose Copilot if you want reliable completions in your preferred editor without switching IDEs.
