TikTok develops separate US app to split algorithm, user data

TikTok is developing a US-specific app that will operate on an independent algorithm and data system, according to sources familiar with the initiative.

This project, internally referred to as “M2,” is expected to be completed by September and could lead to a potential sale of TikTok’s U.S. operations.

The new app will function independently, similar to Douyin, the Chinese version of TikTok.

It will use only US user data to train its recommendation algorithms, focusing primarily on content generated within the US.

Existing content is expected to migrate to the new app, but details on the integration of global content remain unclear.

This effort follows increasing political pressure in Washington regarding data security concerns and ByteDance’s ownership of TikTok.

Discussions regarding TikTok’s future are occurring alongside broader trade negotiations between the US and China.

🧠 Food for thought

1️⃣ TikTok’s algorithm split mirrors historical platform bifurcation patterns

TikTok’s plan to create a separate U.S. app resembles ByteDance’s existing dual-app strategy with TikTok and Douyin, which operate as distinct platforms internationally and in China, respectively1.

This move continues a pattern of regional platform separation seen across the tech industry when companies face regulatory pressure, with ByteDance having already maintained separate content policies between its international and domestic Chinese apps since at least 20192.

The separation of TikTok’s recommendation algorithm, considered the company’s “crown jewel” according to multiple sources, represents a significant technical concession that ByteDance previously resisted during the first Trump administration’s divestiture push3.

This strategic shift demonstrates how ByteDance has evolved from its initial resistance to splitting its technology in 2020 to now accepting algorithm separation as necessary for continued U.S. market access.

The company’s willingness to separate its algorithm contradicts China’s 2020 export control rules specifically designed to prevent the transfer of recommendation technology, highlighting the financial importance of maintaining access to TikTok’s 170 million U.S. users4.
