Sci-Fi Story Prompt Generator
Advanced narrative engine for writers and GMs. Features 250+ unique elements, sub-genre filtering, PRNG seeding for shareable prompts, and specific slot locking mechanics.
About
This tool addresses the phenomenon known as "Writer's Block" by introducing controlled stochasticity into the creative process. Unlike simple random word pickers, this generator utilizes a structured narrative syntax (Protagonist + Setting + Conflict + Tech + Twist) to ensure grammatical and thematic coherence.
The engine uses a Linear Congruential Generator (LCG) algorithm to permit "Seeded" generation. This means a specific combination of variables can be reproduced exactly by sharing a seed ID, allowing collaborative writers or Role-Playing Game (RPG) groups to synchronize on a specific prompt without manual transmission.
We employ a strict "No-Repeat" buffer logic to prevent sequential duplicates, ensuring distinct variety in every iteration. The database covers sub-genres ranging from Cyberpunk and Space Opera to Cosmic Horror.
Formulas
The deterministic pseudo-random number generation relies on the standard Linear Congruential Generator recurrence relation:
Where:
X = The sequence of pseudo-random values.
m = The modulus (232).
a = The multiplier (1664525).
c = The increment (1013904223).
