Compare AI tools

	Cursor S	OpenRouter S	GitHub Copilot B	Gamma A
Tagline	VS Code fork that made AI coding actually work.	One API, every model. Pay-as-you-go, no subscriptions.	Microsoft/GitHub's autocomplete. Deep VS Code + JetBrains integration.	AI slide decks that don't look AI-generated.
Category	coding	dev platform	coding	productivity
Pricing	Free + $20/mo Pro + $40/mo Business	Pay per token — model-dependent	Free (limited) + $10/mo Pro + $19/mo Business	Free + $10-$20/mo
Best for	Developers. Non-developers who want to ship working code.	Developers experimenting across models. Apps that want fallback logic.	Teams with GitHub already. Devs who don't want to change IDEs.	Pitch decks, proposals, internal presentations — fast.
Strengths	Tab completion feels like mind-reading Composer for multi-file edits Runs Claude, GPT, Gemini — you pick	300+ models from one endpoint Automatic fallbacks between providers No subscription — just pay what you use	Great enterprise story Works in your existing IDE Chat + autocomplete	Strong templates Decks, docs, webpages Doesn't look generic
Weaknesses	Can feel overwhelming for non-coders Expensive at scale	Slight markup over direct API Some provider features not exposed	Less agentic than Cursor/Claude Code Model quality varies	Locked into Gamma's format Export quality varies
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 model-shopping. I use this for every prototype before committing.	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.
