What to Look For

A promotional avatar tool has to sell one idea quickly, then let you swap the offer without booking another shoot.

• A presenter built from one photo so campaign faces stay consistent.
• Script or uploaded audio with lip sync that lands on the offer line.
• Voice cloning or a broad voice library for brand tone.
• 170+ languages when the same promo ships to more than one market.
• Vertical, square, and widescreen export up to 4K.
• A paid path that is cheap enough to test a new hook this week.
