Product Requirement
A full from-0-to-1 product thinking case: reviewing my project through user needs, scenarios, pain points, solution, metrics and roadmap — proving not just "I built it", but "I know why and for whom".
One-liner: an immersive memory-assist tool for readers of a 2,000+ chapter xianxia novel — when they "forgot what happened earlier", use it to instantly recall characters, plot, world-building.
Form: 5-page offline frontend app, zero framework, zero dependency, runs from a single folder.
Value prop: not replacing reading, but lowering the "memory cost" of long serialized fiction.
The Binge-reader · XiaoBei
Slow updates, long gaps — forgets everything when returning. Needs "one-tap recall" of the last arc.
The Fragmented Reader · ACha
Reads in fragments (commute, bedtime), confuses relationships. Needs "who is this" quick lookup.
The Deep Reader · AJiu
Wants to look up sects, techniques, geography. Needs a structured, searchable info base.
Scenario 1 · Binge gap
Pain: after months away, main plot / side characters / foreshadowing all blur. Need: quickly regain the story thread.
Scenario 2 · Character confusion
Pain: hundreds of characters, complex relationships. Need: searchable, filterable character database.
Scenario 3 · Heavy world-building
Pain: realms, sects, geography, techniques form a huge system. Need: structured display + three-world map.
Scenario 4 · Immersion
Pain: pure text feels dry. Need: themed BGM and visual atmosphere.
Characters · "Life Cards"
Search, filter, keyboard nav, immersive scroll modal — solves "character confusion".
Plot · "Immortal Path"
Realm-orbit timeline + key events — solves "binge gap".
World-building · "Ascension Steps"
Realm ladder, law cards — solves "heavy system".
Map · Three Worlds
World switch, region hover — geography visualization.
Immersion
App-shell + iframe architecture for seamless BGM — solves "immersion".
North Star
Recall success rate
Can a reader find what they're looking for on the first try (search hit × task completion).
Activation
Usage & retention
Weekly active, session length, character-page usage, map/timeline reach.
Experience
Immersion & stability
Seamless BGM rate, offline reliability, load time.
Growth
Content-driven
Character cards & map as shareable assets → natural virality.
This review demonstrates: I can take an idea from user needs and decompose it into product solution, metrics and roadmap — the core way a product manager works.
