TikTok is to take on social media rival, Instagram, by launching a photo-sharing app, El.kz cites BBC.
The company said it was working on a "dedicated space" for images and text.
Some users have received notifications saying their photo posts will be shared to a new "TikTok Notes" app unless they opt out.
It is the latest example of social media firms imitating each others' products - including Instagram launching Reels, a TikTok-like video tool, in 2020.
“The copycat phenomenon runs rampant across social media platforms", Mike Proulx, a research director at analysis firm Forrester, told the BBC.
When done well copycat features "pay off", he added, giving the example of when Instagram copied Snapchat with its "Stories" feature.
However, he pointed out a similar move by Twitter ended in failure, so there was no guarantee of success.
Instagram's focus on making Reels more central to app has previously frustrated some users.
Kim Kardashian and Kylie Jenner were among those who shared a petition calling out changes to the platform that seemed to promote Reels over other features of the app in 2022.
Instagram U-turned on the changes after the backlash.
