How to Post Someone Else's TikTok on Your Account

You’ve found an amazing TikTok video - a perfectly timed joke, an incredible tutorial, or a hot take that you completely agree with - and you know your audience would love it. The next logical step is to share it, but how do you post someone else's video on your own TikTok account without stepping on toes or breaking the rules? This guide covers the right ways to share content, focusing on TikTok’s built-in tools that make it easy to give credit where it's due and add your own unique perspective.

Why (and When) You Should Share Someone Else's TikTok

Reposting or curating content can be a powerful part of a social media strategy. It’s not about taking a shortcut or being lazy, when done thoughtfully, it adds value to your profile and fosters a sense of community. Here are a few great reasons to incorporate other creators' videos into your content calendar:

• User-Generated Content (UGC): If you’re a brand, sharing videos from customers who love your product is one of the most effective forms of marketing. It’s authentic social proof that builds trust with your audience.
• Content Curation: Sharing relevant videos from other creators in your niche positions you as a trusted source for high-quality information or entertainment. You become a hub for the best content on a specific topic.
• Joining Trends and Conversations: TikTok runs on trends. Using tools like Stitch and Duet allows you to participate in trending conversations, challenges, and memes, keeping your content relevant and increasing its potential for visibility.
• Building Relationships: Highlighting another creator's work is a great way to show appreciation and start building relationships with others in your space. Creators appreciate the exposure, and it can open doors for future collaborations.

The Most Important Rule: Credit and Permission

Before we get into the "how," we have to talk about the most important part: ethics and attribution. The internet is full of "content curators" who are simply content thieves - downloading and re-uploading other people's work without permission or credit. This isn't just bad etiquette, it’s a violation of copyright and TikTok's Community Guidelines that can get your content removed or your account penalized.

The golden rule is simple: always give clear, unmissable credit to the original creator.

The best and safest way to do this is by using TikTok's built-in features, which are specifically designed for collaboration and sharing. These tools automatically link back to the original video, ensuring the creator gets the credit they deserve.

How to Repost Using TikTok’s Built-In Features (The Right Way)

Instead of manually downloading and re-uploading a video (which we don't recommend), use the tools TikTok provides. Stitch and Duet are designed for this exact purpose, making reposting a collaborative act rather than a simple copy.

Method 1: Stitching a Video

A Stitch allows you to clip and integrate a moment from another user’s video into your own. It works perfectly for adding commentary, continuing a story, asking a question about the video, or sharing your reaction to a specific scene. The original video is automatically credited in your new video’s caption.

Step-by-Step Guide to Stitching:

1. Find the video you want to Stitch. Scroll through your For You page or search for a specific video you have in mind.
2. Tap the "Share" button. This is the arrow icon on the right side of the screen.
3. Select "Stitch" from the options. A menu will pop up at the bottom. The Stitch icon looks like two linked rectangles. Note: If you don't see the Stitch option, it means the original creator has disabled this feature for their video. Respect their choice and find another video.
4. Trim the original clip. You can select up to five seconds from the original video. Drag the trim bars on the timeline to pick the exact moment you want to feature. This is the "setup" for your video.
5. Record your addition. After selecting your clip, you’ll be taken to the recording screen. The trimmed clip will play, and then the camera will activate for you to film your response, your commentary, or whatever you want to add. You can record one or more clips until you’re happy with your addition.
6. Edit and post. Once your recording is complete, you can add text, stickers, effects, and a voiceover just like any other TikTok. When you get to the posting screen, you’ll notice that TikTok has already added credit to the original creator in your caption (e.g., "#stitch with @username"). Don't remove this credit! Write your caption, add relevant hashtags, and post.

When to use Stitch: Use Stitch when a short clip from someone else's video provides the perfect context or jumping-off point for your own content. It’s great for creating response videos, fact-checking, or sharing a hilarious reaction.

Method 2: Dueting a Video

A Duet places your video side-by-side with another user's video, both playing at the same time. This format is hugely popular for reaction videos, dance challenges, and lip-syncing battles. Like Stitch, Duet automatically credits the original creator.

Step-by-Step Guide to Dueting:

1. Find the video you want to Duet.
2. Tap the "Share" icon. Just like with Stitch, find the arrow on the right side.
3. Select "Duet" from the pop-up menu. The Duet icon looks like two circles overlapping. Again, if the option is missing, the creator has disabled it.
4. Choose your layout. You'll be taken to the recording screen where the original video plays on one side. You have several layout options available on the right-hand panel, including the classic side-by-side, a green screen background of the video, or a top-and-bottom format.
5. Record your video. Hit the record button and film your video alongside the original. You can react, sing along, follow a tutorial, or add your part to a trend. The original video’s audio will typically play while you record, but you can choose to use your mic’s audio instead if you want to provide commentary.
6. Edit and post. Add any desired effects or text. On the final page, write your caption. The original creator credit will be automatically included in the caption. Post it for the world to see!

When to use Duet: Duet is ideal for direct, real-time reactions and collaborative videos. It’s the standard for dance challenges, the "sing with me" musical trend, and side-by-side comparison or reaction content.

Best Practices for Ethical and Effective Reposting

Using Stitch and Duet is the technical "how," but a great content curation strategy requires a bit more thought. Follow these best practices to make a positive impact and grow your account responsibly.

1. Always Look for Permission First (If Downloading)

If for some reason you feel you must download a video (for example, a customer sent you their UGC via email), you need explicit written permission from the creator to re-upload it. A simple DM to a creator saying, "I love this video you made about our product! Would you mind if we shared it on our page? We'll give you full credit in the caption," is often all it takes.

2. Never Remove Watermarks

Manually reuploading a video often strips out the TikTok watermark that credits the original creator. Do not use shady third-party tools to remove watermarks. A video without a watermark implies you created it, which is deceptive and unethical.

3. Give Credit Prominently

Even if you have permission and are re-uploading, proper credit is non-negotiable. TikTok’s built-in features handle this perfectly. If you are ever posting manually, the credit should be the very first thing in your caption. For example: "Amazing insight from @username!". Don't hide the tag in a sea of hashtags at the end.

4. Add Your Own Value

The best reposts are transformative, not just copies. Stitch and Duet have this principle baked right into their design. You aren't just taking something, you're adding to it. Your commentary, reaction, or perspective is what makes the new video interesting and valuable to your audience. Ask yourself: "What am I adding to this conversation?"

5. Curate Content That Fits Your Brand

Don't just repost any viral video. The content you share should align with your niche, core message, and brand identity. If you're a finance expert, sharing user-generated videos of people crushing their debt using your tips is on-brand. Sharing a random dance trend might not be. A consistent curation strategy shows your audience that you understand them and what they find valuable.

Final Thoughts

Knowing how to post someone else's TikTok on your account is a valuable skill for building a vibrant, community-focused presence. By prioritizing ethical practices and using the platform’s native tools like Stitch and Duet, you can share incredible content, join trending conversations, and highlight creators while giving them the full credit they deserve.
