Plans and AI credits
Choose the plan that fits your document workflow
Every plan uses Aistotel's high-quality document intelligence. Subscriptions give you the best value, larger limits, export access and deeper review tools.
Start free with 100 AI credits. The first 500 words of each document are always free. Larger documents use credits based on word count. You can edit and preview for free, but export requires paid credits or an active subscription.
