	GitHub Copilot B	Cursor S	Claude Agent SDK S	Raycast AI S
Tagline	Microsoft/GitHub's autocomplete. Deep VS Code + JetBrains integration.	VS Code fork that made AI coding actually work.	Anthropic's SDK for building your own agents on Claude.	Mac launcher + AI. Command-bar genius.
Category	coding	coding	agents	productivity
Pricing	Free (limited) + $10/mo Pro + $19/mo Business	Free + $20/mo Pro + $40/mo Business	API usage + SDK is free	Free (app) + $10/mo AI
Best for	Teams with GitHub already. Devs who don't want to change IDEs.	Developers. Non-developers who want to ship working code.	Developers building custom agents for their own company/product.	Power users on Mac who type a lot.
Strengths	Great enterprise story Works in your existing IDE Chat + autocomplete	Tab completion feels like mind-reading Composer for multi-file edits Runs Claude, GPT, Gemini — you pick	Production-grade agent primitives Built on Claude (best reasoning) Full control — build exactly what you need	Invoke AI from anywhere on Mac with a hotkey Choose your model (Claude, GPT, etc.) AI Commands for repeatable workflows
Weaknesses	Less agentic than Cursor/Claude Code Model quality varies	Can feel overwhelming for non-coders Expensive at scale	Developer-only You build the UI	Mac-only Monthly AI sub on top of free app
Kai's verdict	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	S-tier for coding. If you write code of any kind, this pays back the $20 in a day.	S-tier for builders. The right primitives. What Kai is built on under the hood.	S-tier if you're on Mac. The fastest way to get AI answers without context-switching.
