What All Knowledge does

All Knowledge (全知识), also branded as All History (全历史), is a Chinese digital humanities platform operated by Beijing Perfect Knowledge Technology Co., Ltd. that uses AI-powered knowledge-graph technology to visualize and connect historical data across time, space, and relationships. The platform maps more than 5,000 years of Chinese and world history across 30+ countries and civilizations through interactive timelines, spatial-temporal maps, relationship graphs, and an "AB Path" tool that discovers connection pathways between any two historical entities. Supplementary content includes curated articles, a digital library of ancient Chinese texts (全古籍), genealogy exploration (族谱), and expert-authored historical essays. Distribution is primarily self-serve, via the allhistory.com web platform and native iOS/Android apps, with marketing concentrated on Chinese social platforms (WeChat, Douyin, Bilibili, Kuaishou, Weibo) using QR-code-based app downloads.

The business model is freemium-and-advertising hybrid: the web platform and core features are free, monetization comes from in-app advertising and optional premium subscriptions unlocking advanced AI tools and exclusive content. The primary customer segments are individual history enthusiasts and general consumers in China and the Chinese-speaking diaspora, supplemented by students, educators, and content creators/researchers using the platform as a reference tool. No enterprise pricing tiers or B2B contracts are disclosed; there are no named customer logos or institutional accounts. The horizontally-segmented persona-based approach is reflected in the addressable use cases: timeline exploration, relationship discovery, ancient-text reading, genealogy tracing, and content research.

In Q1 2026, All Knowledge was acquired by iHuman Inc. (NASDAQ: IH) — a publicly listed Chinese interactive education company — alongside Perfect Lingo, for combined upfront payments of RMB 94 million. The acquisition positions All Knowledge as a wholly-owned subsidiary within iHuman's AI-driven product expansion, which is intended to counter demographic headwinds in iHuman's core newborn-population segments by broadening content surface area into AI-powered historical and cultural education. iHuman subsequently appointed new Co-CEO and Chief Strategy Officer leadership to drive cross-sell into its 23.62 million MAU base.

Scale indicators3 records

Recent moves4 records

Expansion highlights4 records

Broad incumbents

• MasterClass: Premium creator-led educational content platform with history/sociology instructors. Comparable premium subscription business model and educational content delivery, though delivery is expert video rather than AI-graph-driven exploration.
• Zhihu (知乎): Major Chinese Q&A and knowledge-sharing platform with significant history/culture verticals. Broader scope than All Knowledge but comparable Chinese-language knowledge-discovery audience and content monetization through subscriptions and advertising.
• Khan Academy: Free global educational platform with structured history curriculum and interactive learning tools. Comparable in free/educational positioning and interactive multimedia learning delivery, though scope is K-12 across all subjects rather than history-specialized.

Others

• Wikipedia: Global multilingual knowledge base covering history extensively. Not a commercial peer, but a direct conceptual reference for All Knowledge's structured-encyclopedia approach; All Knowledge differentiates via AI relationship mapping and visual timelines rather than text articles.
• Bilibili (哔哩哔哩): Major Chinese video platform hosting thousands of dedicated history content creators. Competes for the same Chinese youth history-enthusiast audience via video-first delivery and commands vastly larger distribution.

Direct peers

• Baidu Baike (百度百科): Baidu's Chinese-language encyclopedia platform serving hundreds of millions of users with structured knowledge entries. Closest Chinese-market comparison to All Knowledge's structured knowledge repository, though it lacks AI relationship-graph and timeline-driven discovery features.
• Curiosity Stream: Subscription streaming service focused on factual/history/science documentaries. Comparable in freemium subscription model, history-focused content library, and discovery-driven user experience, though delivery is video-first rather than interactive multimedia.
• History Hit: Subscription-based dedicated history content platform offering documentaries, podcasts, and expert-led articles for history enthusiasts. Comparable in audience (history enthusiasts), business model (freemium + subscription), and content focus (curated history media).
