GirlfriendGPT is an AI companion platform focused on the AI girlfriend experience, with customizable personalities, voice messages, and image generation. It is one of two major consumer brands run by NextDay AI Incorporated, a Montreal, Canada company founded in 2023; the other is SpicyChat AI.
It is important to distinguish the commercial GirlfriendGPT product from the unrelated open-source GitHub project of the same name created by developer Enias Cailliau, which is a Python template for building AI companions. The commercial platform reviewed here is the hosted NextDay AI service operated under domains including gptgirlfriend.online.
The product offers customizable companions where users control personality traits, voice, and generated imagery, and supports uncensored conversation. It uses a freemium model with subscription tiers that unlock advanced voice and image features. The company markets itself as a leading AI girlfriend app with millions of users, though independent user counts are not verifiable.
NextDay AI operates through multiple legal entities, including NextDay AI USA Inc (Delaware) and NextDay AI EU Ltd (Cyprus), with a primary registered address in Montreal, Quebec, Canada. It shares operating heritage and infrastructure with SpicyChat. The company is reported as unfunded on investor databases, and small funding figures appearing on some startup directories are unverified and likely directory artifacts rather than disclosed rounds. Individual founders are not publicly disclosed.
Like its sibling product, GirlfriendGPT is controversial for permitting uncensored adult content and operating with limited mainstream-style moderation.
