Engain is the AI-powered Reddit marketing software: it finds the threads where buyers decide, places comments that read like people, and upvotes them to the top, where 90% of demand and every LLM citation lives. This book gives that machine its brand: Celestial Orange on real design tokens, Inter at documented scales, and a cluster mark drawn like replies branching from a thread. All 38 pages.
What Engain is, the mission in six words, four values and a voice built to survive comment sections.
Three nodes joined like replies branching from a thread: construction, clear space, sizes, colors and misuse.
Inter at the system's real scales, Display 2xl down to Text 2xs, four weights each, with the shipped spec pages embedded.
Not moods, tokens: the Celestial Orange ramp, the neutral scale, three semantic ramps, every value contrast-rated in the shipped spec.
The product's three-step story as a brand asset: find the thread, say it like a human, rise and own.
The evidence engine: Reddit dominates AI citations, zero-click is real, distribution beats domain.
The site, the entry points, why it wins, and the back cover.
The live landing running the system. Scroll it inside the frame.
The evidence engine in production: AI search, Reddit demographics and the zero-click reality, each on-brand down to the last data point.
Real tokens, a documented type system, a mark that draws the product, and an evidence engine arguing the thesis. Five brand books in, this is what the factory does.
