The cheapest AI subscription

The cheapest AI subscriptions cost less than €10 a month: Google AI Plus (€4.99), ChatGPT Go (€8.00) and Grok Plus (€9.52). The typical ~€20 plan is cheapest at Mistral (Le Chat Pro, €17.84).

Entry tiers: cheap but limited

Google AI Plus, ChatGPT Go and Grok Plus are aimed at occasional users: more than the free version, but a smaller allowance and usually without the strongest models.

The ~€20 class

Le Chat Pro (€17.84), Claude Pro (€21.42), Google AI Pro (€21.99), Microsoft 365 Premium (€22.00), Perplexity Pro (€22.00) and ChatGPT Plus (€23.00) are close together. Here, features and ecosystem matter more than price.

How to save even more

Almost every provider gives a discount on the annual plan – €46.00 a year for ChatGPT Plus, €42.80 for Claude Pro. Students get Le Chat Pro cheaper.
