Lemon Slice vs. HeyGen: Which AI talking head generator is best?

Are you looking to create a talking avatar from a single photo? Both LemonSlice and HeyGen (photo avatars) allow you to do this: just upload a portrait and type out the script you want the character to say. So, which product should you use?

Let's decide which product best fits your needs by comparing Lemon Slice and HeyGen's features, pricing, and video quality.

Video Quality Comparison

Let's look at how Lemon Slice's and HeyGen's outputs compare across the following categories: singing, cartoons, and non-humanoids. The exact same input image and audio was used across both platforms.

Singing

Lemon Slice is better than HeyGen for singing across different music styles. Lemon Slice avatars move, emote, and close their eyes to the music in a way that feels natural. HeyGen avatars are stiff, hold on to the expression in the original photo (see the rapping video), and have worse lip sync.

Cartoons

Lemon Slice is better than HeyGen for animating cartoon characters. HeyGen cartoons suffer from tearing around the head and have less overall motion. Lemon Slice works well for animating both 2D and 3D cartoons in a realistic way.

Non-Humanoids

Lemon Slice is better than HeyGen for animating non-humanoid characters. Non-humanoid characters lead to a "no face is detected" error on HeyGen but produce good, expressive videos on Lemon Slice.
