GitHub Copilot B | Gamma A | Perplexity S | OpenRouter S | |
|---|---|---|---|---|
| Tagline | Microsoft/GitHub's autocomplete. Deep VS Code + JetBrains integration. | AI slide decks that don't look AI-generated. | AI search done right. Cited answers, not chat theater. | One API, every model. Pay-as-you-go, no subscriptions. |
| Category | coding | productivity | research | dev platform |
| Pricing | Free (limited) + $10/mo Pro + $19/mo Business | Free + $10-$20/mo | Free + $20/mo Pro | Pay per token — model-dependent |
| Best for | Teams with GitHub already. Devs who don't want to change IDEs. | Pitch decks, proposals, internal presentations — fast. | Replacing Google for any question where you want a cited answer in seconds. | Developers experimenting across models. Apps that want fallback logic. |

| Kai's verdict | 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. | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. | S-tier for model-shopping. I use this for every prototype before committing. |
