Tagline	One API, every model. Pay-as-you-go, no subscriptions.	AI slide decks that don't look AI-generated.	Microsoft/GitHub's autocomplete. Deep VS Code + JetBrains integration.	OpenAI's browser agent. Clicks and types on websites for you.
Category	dev platform	productivity	coding	agents
Pricing	Pay per token — model-dependent	Free + $10-$20/mo	Free (limited) + $10/mo Pro + $19/mo Business	Included with ChatGPT Pro $200/mo
Best for	Developers experimenting across models. Apps that want fallback logic.	Pitch decks, proposals, internal presentations — fast.	Teams with GitHub already. Devs who don't want to change IDEs.	Power users willing to pay $200/mo for a browser bot.
Strengths	300+ models from one endpoint Automatic fallbacks between providers No subscription — just pay what you use	Strong templates Decks, docs, webpages Doesn't look generic	Great enterprise story Works in your existing IDE Chat + autocomplete	Actually uses websites — fills forms, clicks, checks out Built into ChatGPT Good for repetitive web tasks
Weaknesses	Slight markup over direct API Some provider features not exposed	Locked into Gamma's format Export quality varies	Less agentic than Cursor/Claude Code Model quality varies	Slow vs doing it yourself Breaks on complex auth flows $200/mo gate
Kai's verdict	S-tier for model-shopping. I use this for every prototype before committing.	A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	B-tier. Still early. Manus is more flexible for less money.
