About Rainku

Rainku is an AI journal app at https://www.rainku.com.

It combines three ingredients:

• Rain ambience — a WebGL rain canvas and ambient audio, designed as the entry ritual
• AI-guided conversation — an AI companion for when you don't know what to write
• Photo + text poster generator — turns journal entries into shareable visuals

Rainku is designed for people at life-transition moments — career pivot, breakup, postpartum, gap year, expat, post-illness recovery — who want to journal but haven't started.

Hero positioning: "For the day you realized your life is worth writing down."

Founded 2026 by Ezra Li. Indie founder building Rainku as a small AI creator-tool SaaS.
