Once you add a caption to a photo or a video, it is indexed by the Photos app, and you can search for the keywords later. While the Photos app has an automatic search engine for photos, it’s not very specific or reliable. Using captions, you can take control of the photos you know you might like to search through later.

The Photos app automatically groups the same captions, so you can use this feature as a makeshift tagging system. You can give the same one-word caption to multiple photos to quickly find them together.

Open the “Photos” app on your iPhone or iPad and navigate to the photo that you want to add a caption. Next, swipe up on the photo to expose additional options.

This will show you photo information including where the image was taken. Right below the photo, tap the empty text area labeled “Add a Caption.”

Here, type out your caption. Tap the “Done” button found in the top-right corner.

You can repeat the process for all the photos and videos that you want to add a caption to. You can also come back here at any time to edit the caption.

The Photos app will now start indexing the caption. To find a photo or video based on a caption, go to the “Search tab” and then tap the “Search” bar at the top and type in a word or a phrase from one of your captions.

Now scroll all of the way to the bottom of the page. You’ll find a “Captions” section here. Choose a caption to see the photos related to it.

If you have multiple photos or videos will the same caption, you’ll see a photo count on the right edge. Tap the caption to see all photos and/or videos.

When you’re sharing a photo or video using AirDrop or iCloud, the Photos app automatically shares the caption as well. You can disable this from the share sheet. Tap the “Share” button to get to the share sheet.

Select the “Options” button from the top.

Here, tap the toggle next to the “Captions” option to disable sharing photos with captions.
