A princess of Mars

ON THE ARIZONA HILLS

I am a very old man; how old I do not know. Possibly I am a hundred, possibly more; but I cannot tell because I have never aged as other men, nor do I remember any childhood. So far as I can recollect I have always been a man, a man of about thirty.

And because of this conviction I have determined to write down the story of the interesting periods of my life and of my death. I cannot explain the phenomena; I can only set down here in the words of an ordinary soldier.

I spent nearly a year prospecting in company with another Confederate officer, Captain of Richmond.

The problem

Search engines are hostile to readers.

Complex series make you ask tiny memory questions: who is this person, what faction is that, why does this place matter? The open web answers with full-series spoilers. StoryCodex narrows the answer to what your current chapter permits.

Long breaks

Return after a month and review arc summaries, recent events, and the active cast before you continue.

Huge casts

Recall aliases, roles, alliances, and appearances for characters who vanished hundreds of chapters ago.

Lore overload

Keep places, factions, items, concepts, magic terms, and mysteries organized inside the book itself.

Private reading

Your library, reading progress, summaries, and Codex entries are designed around local-first storage and processing.

How it works

A Codex that grows only as far as you have read.

The source backs the public promise: StoryCodex builds chapter summaries, character dossiers, world entities, relationship edges, and timeline events as incremental grounded passes.

1

Bring in a book

Import files or add a web novel. StoryCodex keeps each universe tied to its own Codex key, including linked volumes.

2

Analyze the chapter

The app grounds summaries, entity mentions, world terms, relationships, and timeline events against the text you actually reached.

3

Update the Codex

Profiles, aliases, world entries, graph edges, and chapter recaps grow incrementally instead of dumping a full-series wiki on you.

4

Recall without spoilers

When a name returns 700 chapters later, you get the context that is safe for your current reading progress.

Screenshots

Real app surfaces, framed for the web page.

Current captures show the library, reader, Codex, and Story Map as they appear in the app, with the same device framing used throughout the blog.

Capabilities

Built for people reading worlds, not just pages.

The product is strongest when books are long, names are dense, and lore matters. These are the pieces worth showing off on the homepage.

Characters

Builds spoiler-safe profiles, aliases, appearance counts, current status, and relationship notes as chapters are processed.

World Index

Tracks places, factions, items, concepts, mysteries, and magic systems so dense worlds stay searchable.

Timeline

Stores grounded chapter events and arc summaries, making it easier to return after weeks away from a series.

Relationship Graph

Turns character, faction, and location links into a visual map you can inspect instead of digging through notes.

Neural TTS

Supports local narration engines like Piper, Kokoro, and Supertonic with reader controls always close by.

Private AI

Runs companion analysis through local-first model backends such as GGUF and LiteRT, with optional cloud keys under user control.

Who it is for

Fantasy, web novels, progression fiction, and any series that makes memory expensive.

If a book has families, guilds, ranks, regions, artifacts, or recurring mysteries, StoryCodex gives you a private reference layer that evolves with the story.
