About cutGPT

A product of ZStack Capital LLC

Last updated: August 23, 2026

cutGPT is an ad-supported AI assistant for iPhone and the web. We built it so people can use strong language models without first buying a monthly subscription. Advertising helps pay for inference. When those ads create value, eligible accounts can receive a discretionary share of the ad-funded pool — the “cut.” That share is a promotional program, not wages and not a guaranteed payout. The rules live in our Platform Terms.

Who operates the product

cutGPT is a brand of ZStack Capital LLC, a Delaware limited liability company. We run the iOS app, this website (cutgpt.app), authentication, and the related tools catalog. Support and privacy requests go to [email protected]. More detail is on our contact page.

What cutGPT is for

Everyday writing, studying, career drafts, and follow-up questions — the same jobs people take to a general chatbot, with an honest funding model instead of a paywall. Free browser tools under /tools/ cover writing, citations, career documents, and similar local or AI-assisted tasks. Sign in with Apple or Google; the same account works on iOS and the web.

What we are not

cutGPT is not a medical, legal, or financial adviser, and model output can be wrong. We are not the 2023 “CutGPT” fine-tuning product from One AI; that is a different company and a different product. We do not pay people to tap ads, and interacting with ads does not increase anyone’s share.
