3. Personalized Suggestions

It will serve you two purposes: your user will be happy by sharing their content, and you will get free brand recognition.

5. Download/Delete Videos

If the user made a GIF or a face swap video and changed his/her mind later, then your app should deliver them an option to delete that GIF or video. The same goes with the download feature. This feature will access the storage of the user’s device, and the user has to allow the app for the same. There are various times when users don’t like their edited click or the filters or the apparel color and want to delete it. The highest numbers of the shared contents include the downloaded, edited clicks.

6. Advanced Search Functionality

Your face-changing app should have a search button that will allow the users to browse through their favorite filters and creators. Apart from that, your app should have an advanced search option that will allow users to search for popular clips, filters, etc. This feature should allow users to filter their search results based on parameters such as language, popularity, creator, most used, etc.

7. Upload

Uploading is the essential part of any face portrait ai app, as after spending your time on the app while browsing, searching for the correct filter and editing your click, you will ultimately upload it.

This feature will help your app add the other features or filters unavailable in your app’s library.

These are used for high-fidelity raw image synthesis, enhancing image compression, and augmenting data.
