Looking for a clear product category name

Hi all.
My product doesn't seem to have a defined category in the market so I am trying to find something that will be clear for most English-speaking users.

What the product does (function) — it helps to collect video clips from people and then stitches them together to create a collaborative video. It all works on Facebook Messenger, so it's a chatbot.

What need it serves — it's a great way to make a birthday/wedding/anniversary/retirement/graduation video. A video that brings smiles and tears of joy.

There is some competition in this field and looks like "group video" is the most commonly used term. What comes to your mind when you hear it? Any ideas on how you would call such product category yourself?

Other options I see are "video gift", "surprise video", "birthday video". But everything seems to be unclear to me.

Oh, the link for the product: https://clipsus.app
