You cannot see exactly who saved your Instagram post. Instagram does not provide the identity of users who save your posts, whether you have a personal or professional (business or creator) account. However, if you switch to a professional account, you can see how many times your post has been saved through Instagram Insights, but the specific individuals who saved it remain private.

The saved posts feature is designed to keep the privacy of users who bookmark content, so no one can tell others if they have saved their posts. If you want to gain some insight, you can ask your followers directly using Instagram Stories by posting a screenshot of your post and asking who saved it, but this relies on their honesty and willingness to respond.

In summary, while you can see the total number of saves on your posts with a professional account, knowing exactly who saved them is not possible on Instagram.
