Compare AI tools

	Cursor S	Perplexity S	Claude Code S	Cline A
Tagline	VS Code fork that made AI coding actually work.	AI search done right. Cited answers, not chat theater.	Anthropic's CLI agent. Opus-powered, operates on your repo directly.	Open-source VS Code agent. Reads + writes + runs.
Category	coding	research	coding	coding
Pricing	Free + $20/mo Pro + $40/mo Business	Free + $20/mo Pro	Part of Claude Pro/Max/Team plans	Free (open source) + your API costs
Best for	Developers. Non-developers who want to ship working code.	Replacing Google for any question where you want a cited answer in seconds.	Developers who want an agent, not autocomplete. Large refactors, tests, docs.	VS Code users who want agentic coding without changing IDEs.
Strengths	Tab completion feels like mind-reading Composer for multi-file edits Runs Claude, GPT, Gemini — you pick	Sources every claim Fast, current answers Pro Search runs multi-step research Spaces for persistent context	Runs locally, edits your actual files Strong on large codebases with 1M context Great at multi-step tasks	Free extension for VS Code Plan + Act modes Model-agnostic (Claude, GPT, local) Sees terminal output and iterates
Weaknesses	Can feel overwhelming for non-coders Expensive at scale	Not a general chatbot Answers can be shallow on complex topics	Terminal-based — learning curve Can't be used without Claude subscription	Can burn tokens fast if not watched Less polished than Cursor
Kai's verdict	S-tier for coding. If you write code of any kind, this pays back the $20 in a day.	S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.	S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.	A-tier. Best free agentic option in VS Code. Use with Claude for best results.
