Compare AI tools

	GitHub Copilot B	Grammarly A	Stripe Link A	Cursor S
Tagline	Microsoft/GitHub's autocomplete. Deep VS Code + JetBrains integration.	Grammar check + tone + AI drafting, everywhere you type.	A digital wallet that lets AI agents spend on your behalf — without ever seeing your actual card number.	VS Code fork that made AI coding actually work.
Category	Coding	Writing	Agents	Coding
Pricing	Free (limited) + $10/mo Pro + $19/mo Business	Free + $12-$15/mo Premium + team plans	Free for consumers; standard Stripe per-transaction fees for merchants	Free + $20/mo Pro + $40/mo Business
Best for	Teams with GitHub already. Devs who don't want to change IDEs.	Non-native English writers, business email, anyone who types a lot.	Anyone running autonomous AI agents (shopping bots, booking assistants, personal AI) who wants delegated payment capability without handing over raw card data.	Developers. Non-developers who want to ship working code.
Strengths	Great enterprise story Works in your existing IDE Chat + autocomplete	Works in every browser/app Now has generative AI (GrammarlyGO) Tone detection + suggestions	First mainstream wallet with a built-in agent authorization layer — AI agents get one-time-use cards, not your real credentials OAuth-based approval flow means you review every agent spend request before payment credentials are shared 250M+ existing Link users means instant network coverage at hundreds of thousands of Stripe-powered merchants Developer-friendly: agent builders can use Link's wallet infra instead of rolling their own payment rails Subscription tracking, auto payment-method updates, and 90-day purchase protection bundled in	Tab completion feels like mind-reading Composer for multi-file edits Runs Claude, GPT, Gemini — you pick
Weaknesses	Less agentic than Cursor/Claude Code Model quality varies	Can feel naggy Premium features gate basics Privacy concerns (reads your writing)	Stablecoin, agentic token, and BNPL agent-payment support is still 'coming soon' — traditional cards only at launch Per-transaction approval flow can be tedious for high-frequency agent tasks until spending-limit presets ship Merchant adoption for agent checkout paths is still early; real-world agentic commerce coverage is thin	Can feel overwhelming for non-coders Expensive at scale
Kai's verdict	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.	Stripe Link is the most credible first move toward a real agentic payment layer — the one-time-use card model is genuinely clever, and the existing merchant network gives it a head start no startup wallet can match. But the 'approve every transaction' UX will get old fast, and the hard part (autonomous spending with guardrails) is still on the roadmap. (Verdict pending Phi's full review.)	S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
