Cursor S | Claude Code S | Ollama S | Grammarly A | |
|---|---|---|---|---|
| Tagline | VS Code fork that made AI coding actually work. | Anthropic's CLI agent. Opus-powered, operates on your repo directly. | Run LLMs locally. One-line install, GUI optional. | Grammar check + tone + AI drafting, everywhere you type. |
| Category | coding | coding | dev platform | writing |
| Pricing | Free + $20/mo Pro + $40/mo Business | Part of Claude Pro/Max/Team plans | Free + open source | Free + $12-$15/mo Premium + team plans |
| Best for | Developers. Non-developers who want to ship working code. | Developers who want an agent, not autocomplete. Large refactors, tests, docs. | Devs wanting offline/local LLMs for privacy or experimentation. | Non-native English writers, business email, anyone who types a lot. |

| Kai's verdict | S-tier for coding. If you write code of any kind, this pays back the $20 in a day. | S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement. | S-tier for local inference. If you care about privacy or want to tinker, install this today. | A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone. |
