SpicyChat AI is a free-to-start AI character-chat platform built around uncensored roleplay and user-generated characters. It is one of two major consumer brands operated by NextDay AI Incorporated, a Montreal, Canada company founded in 2023; the other is GirlfriendGPT.
The product centers on a community character library, a custom character creator, and a proprietary model marketed as SpicyXL. Memory is tiered by subscription, with free users getting smaller context windows and paid tiers unlocking larger memory (commonly up to 16K tokens), faster generation, and image features. The platform supports both safe-for-work and explicitly adult roleplay.
Despite being listed as unfunded on investor-tracking databases, SpicyChat has reached enormous consumer scale. The company reported 100 million registered users by the end of 2025, roughly 28 months after launch, and third-party analytics estimate it at around 52 million monthly site visits. It was notably included in Andreessen Horowitz's 2025 consumer AI rankings alongside mainstream products like ChatGPT and Gemini.
NextDay AI operates through multiple legal entities, including NextDay AI USA Inc and NextDay AI EU Ltd, with a primary registered address in Montreal, Quebec. The founders are not publicly disclosed, which is common for adult-AI companies.
SpicyChat remains controversial for permitting uncensored adult content and operating with limited mainstream-style moderation. However, its traffic, user count, and industry recognition make it one of the most significant independent AI companion platforms in the market.
