Lists of 30 App

AI co-writer and creator platform for structured 30-item lists, with a 400+ catalog and community submissions.

ReactSupabaseViteClaude API

A creator community platform built on the idea that everyone has 30 things to say about everything. Browse 400+ published lists, write your own with an AI co-writer trained on the Clemens Wan voice, and submit to the community.

What It Is

Lists of 30 is built around a simple constraint: every topic deserves exactly 30 things said about it. Not 10 tips. Not an infinite scroll. Thirty considered, escalating items, from the obvious to the philosophical.

The app is simultaneously a showcase of Clemens Wan’s 400+ published lists, a tool for anyone to write their own, and a community layer where users submit, suggest topics, and get AI-assisted support from a co-writer trained on the Clemens Wan voice.
