How it works

From idea to a world in three doors.

PocketPlot Universe is the only writing platform that builds the story with you — branching choices, original art, and an engine you can shape yourself. Here's the full tour.

01

Imagine a world.

Open /worlds/new and pick a title, a genre (fantasy, sci-fi, noir, romance, adventure, horror), a tone (hopeful, grim, romantic, mysterious, comedic, epic), and a setting. The world is yours from line one.

Free and Pro tiers use the deterministic procedural engine — same seed produces the same story. Creator tier can route through your own LLM for richer output.

  • Free: 3 short stories / day, max 300 words each
  • Pro: unlimited stories, max 3000 words
  • Creator: unlimited stories, max 5000 words + BYOB LLM
02

Pick an engine.

Two engines, same interface. The default procedural engine draws from in-house word pools — original prose, no LLM, no chance of reproducing copyrighted material. The optional BYOB engine plugs your own OpenAI-compatible endpoint (OpenAI, OpenRouter, LiteLLM, Together, Mistral, Groq, or any local model with an shim) into the prose pipeline.

Both engines pass through the same content filter. Both produce original output. Both are yours to export.

Privacy & encryption: API keys are stored encrypted at rest with PBKDF2 + HMAC. We never log the plaintext. You can delete them anytime.

03

Read, choose, branch.

Each episode opens with a 400-word beat. At the end of the beat, three doors appear — each one a different continuation. You pick one; the world's state updates; the next episode generates from there.

Up to ten episodes per world. After ten, the world concludes — you can start a new one, export the whole story as markdown, or just walk away.

Along the way, the engine tracks your Word Vault (every unique Word of the Day you've met), your streak (consecutive days of engagement), and eight badges (first story, first game, streak keeper, week-1 wonder, 10/25/50 words, fortnight streak).

Side-by-side

How the engines compare.

Default · all tiers

Procedural engine

Original prose from curated word pools. Deterministic: same seed produces the same story.

Strengths: zero external cost, zero hallucination, instant, fully private.
Limits: slightly stiffer prose; less variation across genres.

Optional · Creator tier

BYOB LLM engine

Routes to your OpenAI-compatible endpoint. You bring the API key and model; we route the request and apply the content filter.

Strengths: richer prose, your favorite model, configurable.
Limits: 100 external-API calls / day, costs on your provider.

Frequently asked

Top questions, fast answers.

How long does it take to start?

About 90 seconds. Email, display name, age (18+), check the boxes, hit Begin. Your first story arrives in your inbox (or the outbox folder) immediately.

Will my stories train any model?

No. Your stories are yours. We don't train anything on them, we don't sell them, and we don't share them.

What happens to my worlds if I cancel?

They stay in your account as read-only archives. Re-subscribe anytime and they're still there.

Can I bring my own LLM and image API?

Yes — that's the Creator tier's whole point. Both go through the same content filter as the procedural engine. Paying for Creator doesn't unlock content that violates platform policy.

What content is allowed?

Light violence, light romance, mature themes, strong language in moderation. Not allowed: NSFW, graphic gore, anything depicting minors in sexual contexts, hate speech. Full Content Policy →
