Unspoken gratitude, suddenly resurfacing memories.

Open the stationery and freely write what you want to tell your departed pet.

"Rainbow Post" is an app that allows you to receive replies and illustrations created by a generative AI, starting with the letter you send.

■ Please Read First

All replies in this app are fictional creations by the generative AI. They are not the words of your actual pet. They do not represent your pet's wishes or current state. Please use this app with this understanding.

■ How to Use

1. Write your pet's name and what kind of pet they were.

2. Write what you want to tell them on the stationery.

3. Select one photo (required).

4. Seal and send.

5. Receive a reply and illustration instantly.

From then on, a new letter will arrive daily at a set time. You can write replies to received letters, and your sent replies will remain on the same screen. Received replies can be reread within the app even after canceling your plan.

■ Illustrations Created from Photos

Using the expressions and colors in the photos as clues, the app generates illustrations that resemble layers of watercolor and colored pencils. These illustrations are also created by the AI ​​and are not the original photos.

■ Regarding the Use of the AI

• The reply text and illustrations are created by the AI ​​based on the input content and photos.

• These are not actual words spoken by the pet, nor do they represent its intentions or state.

• The photos and letter content you provide will only be used to create the reply and for quality improvement and safety checks.

• This app is not intended for medical practice, diagnosis, or treatment, and is not a substitute for professional assistance. If your distress persists, please contact a professional support service.

■ Free Features

- You can send your first letter and read the first few lines of the reply.

- Illustrations are displayed with a thin overlay (images are not blurred).
