What you can create

Diary text

Centered on your own mood and daily highlights: you write the feelings and moments; the system helps shape them into savable diary text.

Poem

An AI-generated poem matched to the day’s mood and diary tone — another way to keep the memory.

Narration voice

Four default voices spanning Chinese and English, so diary or poetry can be read aloud for listening and video.

Hero image

Use an AI-generated mood visual, or upload your own daily photo as the image for diary and short video.

Music

AI-generated matching music that follows the day’s emotion and pacing.

Personal video diary

Combines text, poem, narration, visuals, and music into a personal video diary — keep it private, or post to social accounts you authorize.
