ChatGPT vs Claude vs Gemini — Which AI Subscription Is Worth It?

Updated April 2026. Compare pricing, features, and overlap across the top AI assistants.

Do you subscribe to more than one?

ChatGPT, Claude, and Gemini overlap 95% in features. Most users only need one. SubDiet detects these overlaps and shows how much you can save.

Platform	Free Tier	Paid Plan	Best For
ChatGPT	GPT-4o mini, 10 msg/5hr	$20/mo Plus	All-rounder, plugins, DALL-E
Google Gemini	Gemini 2.5 Flash, unlimited	$19.99/mo Advanced	Google ecosystem, 2M context
Claude	Sonnet, 5-10 chats/day	$20/mo Pro	Coding, long documents, natural writing
Perplexity	Basic search	$20/mo Pro	Research with sources
Microsoft Copilot	Basic GPT-4	$20/mo Pro	Office 365 integration

Are You Paying for the Same Thing Twice?

If you subscribe to both ChatGPT Plus and Claude Pro, you're paying $40/month for tools that overlap 95%. That's $480/year you could save by picking one. The same applies to many other combinations — GitHub Copilot and Cursor share 85% of features, and ChatGPT Plus already includes DALL-E, making a separate Midjourney subscription partially redundant.

SubDiet automatically detects these overlaps and calculates your potential savings — no signup, no bank connection, free forever.

How We Compare AI Subscriptions

Every data point on SubDiet is sourced directly from each platform's official pricing page. We track pricing changes across 60+ AI tools and update our database regularly. Our comparison methodology considers:

Subscription pricing — Monthly, annual, and free tier details for every plan.
Feature overlap — Which tools do the same things? Our overlap detection engine analyzes shared capabilities across categories.
Value per dollar — What do you actually get for your $20/month? Message limits, model access, storage, and bundled features all factor in.
Category fit — The best tool depends on your use case. A developer needs different capabilities than a content creator or researcher.
