The AI tool allows the user to create personalized audio messages from a Christmas elf. Users can enter a message (max 120 words), along with the recipient's name and email address. The tool assigns a specific elf to record the message, which is then delivered to the recipient's inbox. The tool also offers a 25% discount for early Christmas orders. Pricing information ranges from £2.97 to £5.99, with a small record fee to cover wages for the assigned elf.
