About This Tool

SynClub is an AI social product launched by Baidu through its Japanese subsidiary HiClub, primarily targeting the Japanese market. Its core selling point is over 1,000 Japanese anime-style voices covering students, childhood friends, mature women, idols, and more. AI responses use a three-layer structure: construct an event scene, generate a text response, then 'perform' it through voice — the Japanese version achieves exceptionally high naturalness. Features include voice calls, highly customizable characters (personality/appearance/tone/worldview), AI image generation, and AI comic creation. A 'Secret Settings' feature allows users to assign hidden background information that influences character behavior without being explicitly stated. The app reached the TOP 10 of Japan's AI app revenue rankings in the first half of 2025, with over 500,000 cumulative downloads.

Background

SynClub was developed by Baidu's Japanese subsidiary HiClub (formerly Baidu Japan K.K.), launching in 2023. Positioned as an AI social platform targeting the Japanese market, it follows a 'casual social, virtual town' approach. Baidu gained deep understanding of young Japanese users through Gravity, an anonymous social product with over 1 million downloads.

Technology

Features a three-layer response generation architecture: scene construction → text generation → voice performance. Supports automatic multi-language detection. Integrates AI image generation, AI comics (using Claude models), and AI video generation. Built-in NSFW keyword detection and suicide prevention mechanisms.

Market

Strong performance in the Japanese market, entering the TOP 10 of Japan's AI app revenue rankings in H1 2025. Japan's national broadcaster NHK featured its suicide prevention system in an 8-minute segment. A character creation contest received over 100,000 submissions. Main competitors include Character.AI, LoveDovey, and others.
