Mocha Casa turns a familiar pet into a small Windows desktop companion. We wanted the feeling of having your dog or cat nearby while you work: a stretch, a slow walk, a little response when you give them attention.

The free Windows client and Mocha sample are available now. Choose the calmer Companion mode or a livelier Active mode, adjust size and position, hide and restore the pet, and add optional water, movement or custom reminders. Reminder details are kept locally.

Personalized pets are made to order from dog or cat photos, using AI-assisted animation and team review. This is not an instant photo generator inside the app. Import the finished .mochapet file into the client to use your own companion.

Building it taught us that believable companionship depends on more than animation: footsteps must match window movement, brightness needs to stay consistent between actions, and settings should not hide the pet. We would love feedback on the balance between quiet presence and playful interaction.

The demonstration uses edited, normal-speed Windows client footage. This is a desktop companion, not a chatbot.
