Frequently asked questions
What is the best AI pet generator in 2026?
It depends on what you want. For a Codex desktop companion, you need a generator that outputs an animated spritesheet plus pet.json — PetGen is purpose-built for this. For a one-off portrait or avatar, general AI tools work, but they will not produce an installable, animated desktop pet.
Can any AI image generator make a Codex pet?
Not directly. Codex expects a specific spritesheet grid plus pet.json metadata. Generic generators produce a single picture, not a packed animation sheet in the right format. You either need a Codex-aware generator or you must manually slice and assemble frames.
What should I look for in an AI pet generator?
Check four things: whether it outputs an installable spritesheet + pet.json, how many animation states it creates, whether it removes the photo background for you, and the price. Free generators that handle the full pipeline save you the most time.
