Instagram has launched a new video editing tool called Reels that copies some of TikTok's best-known features.
It is currently being tested in Brazil and it is unknown whether it will be launched in other countries.
With Reel, users can record 15-second videos and then adjust their speed, set them to music, or use audio from other videos.
These videos can be shared onto users' stories, via DMs, or posted into a new 'Top reels' section of the Instagram Explore tab.
Facebook has previously tried to copy TikTok's success but found it difficult to build a user base from scratch.
TikTok has seen huge growth but it is currently facing trouble from regulators, including a US national security review.
