The reader that never loses the plot.

NovelForge reads your books so it can help you read them: a character codex, a relationship graph, and search across every downloaded chapter — all on your phone, none of it spoiling you.

Relationship graph · live
Your reading position Ch. 140

This is the app's actual behavior. The graph is built only from chapters you've read — drag forward and watch characters appear the moment you'd meet them. Hover a character to trace their bonds.

Chapter I · the premise

Built for how you actually read.

Most reading apps assume you read in ten-minute commutes. This one assumes you're eleven hundred chapters into something, you have four more books in rotation, and you just hit a name you haven't seen since last March. Other apps leave you to scroll back. NovelForge answers: who they are, when you met them, and every scene they've been in — without revealing a single chapter you haven't reached.

That's the idea across the whole app. Offline by default, because you read on flights. Eleven themes, because your eyes change as the day goes on. Stats that stay on your phone, so you can think "huh, I read more than I thought" without a dashboard somewhere thinking it too.

The whole thing is free. The source is open. Whatever's on your phone stays there.

Chapter II · the codex

"Wait — who is this again?" Solved.

The feature no other reader has, built for the question every long-series reader asks.

Character codex

Every character, indexed on your phone.

NovelForge scans your downloaded chapters — on-device, no cloud — and finds every recurring character, place, and faction. Each entry shows when they first appeared, how often they turn up, a presence sparkline across the whole book, and every mention with a snippet. Tap a mention and the reader opens at that exact paragraph.

The spoiler guard is structural, not a checkbox: entries and mentions are cut off at your current chapter, so a character you haven't met doesn't exist yet, and one you have can't leak future scenes.

  • Characters, places, and factions — detected automatically
  • First appearance, mention timeline, your highlights about them
  • Spoiler-safe by construction, toggleable when you want to peek
Relationship graph

Who appears with whom — drawn, not listed.

The graph you tried up top is the real feature: characters sized by how often they appear, connected when they share chapters, laid out so factions cluster and loners drift to the edges. Tap two characters and get every chapter they share; tap a chapter and you're reading the scene.

Because it's built only from chapters behind your bookmark, the graph grows as you read. Finishing an arc literally redraws the map.

  • Force-drawn map of your story so far
  • Tap any two characters for their shared scenes
  • Pinch to zoom; updates as your position moves

Chapter III · search & recall

Your library, greppable.

Full-text search

"Where did I read that?" takes two seconds.

Every downloaded chapter is indexed on-device. Type a name, a phrase, half a memory — results come back grouped by book, with the match bolded in context. Tap one and the reader opens scrolled to that paragraph, not just that chapter.

Inside a chapter, a find bar does the same at close range: every occurrence marked, next and previous, works in both scroll and paged mode.

  • Search across every downloaded chapter, instantly
  • Jump straight to the matching paragraph
  • In-chapter find with match highlighting
Margins

Highlights, bookmarks, and a way back to them.

Long-press a paragraph to bookmark it with a note. Select text to highlight in six colors. Everything is searchable, everything exports as JSON, and the codex cross-references your highlights — open a character and see every line you've ever marked about them.

Reading history keeps the trail: every session, every book, so "the thing I was reading two Tuesdays ago" is an actual query the app can answer.

  • Six highlight colors, notes on bookmarks
  • Highlights and notes export for safekeeping
  • Session-level reading history

The Long Quiet · 1/20 · ~3 min
Chapter 1

The town held its breath when the river started to freeze that year. By December the surface was thick enough to walk on, and the children dared each other to cross the bend by the old mill where the ice was thinnest.

Marin watched them from the window of the bookshop, her tea going cold in her hands. She had not yet decided whether to tell anyone what she had found in the back room three days earlier — the box of letters, the inscriptions in a hand she almost recognized.

Outside, a boy slipped and fell laughing onto the ice. His friends pulled him up. The river held. The bookshop bell did not ring all afternoon.

Chapter V · the audio

Text-to-speech that sounds good.

The audio

Three engines, one pronunciation dictionary.

Your device's system TTS out of the box, plus Piper and Kokoro neural voices you download in-app when you want better. Speed, pitch, volume, sentence gaps, paragraph gaps — separately adjustable, with a sleep timer for reading yourself out.

The pronunciation dictionary fixes the words your engine keeps mangling — character names, place names, invented terms — and can silence the ones you'd rather it skipped entirely, like the stray asterisks and scene-break marks that come out as "asterisk". Save it as JSON, load it on another device. And when a book deserves a run or a commute, generate a proper M4B audiobook with chapter markers.

  • System TTS plus Piper and Kokoro neural voices
  • M4B audiobook export with chapter markers
  • Sleep timer; audio focus respects calls and other media
Chapter VI · the numbers

Your reading, kept honest.

The stats

Words, streaks, records — counted on your phone.

Words, chapters, time, streaks. A 12-week heatmap. Personal records for longest session and best day, week-over-week deltas so you can see whether you're trending up or just remembering selectively. A home-screen widget puts the book you're on one tap away.

All of it is computed locally. There is no analytics service watching what you read — there's nowhere for one to live. Share a weekly summary card if you want; that's your call, made per-card.

  • Daily, weekly, and all-time stats with records
  • 12-week heatmap, streaks, shareable summary cards
  • Continue-reading home-screen widget
Chapter VII · everything else inside

The rest of the shelf.

Library

EPUB, text, or Markdown in. EPUB out.

Import any .epub, .txt, or .md — cover, chapters, and metadata extracted automatically, with chapter breaks detected from headings, chapter lines, or scene breaks. Export any book back to a clean EPUB for archiving or another reader. Your files never stop being yours.

Reading modes

Scroll, page, or drift.

Infinite scroll for binge nights, paged mode with slide, fade, or curl transitions when you want to slow down, and a teleprompter auto-scroll from 20 to 200 px/s for hands-free reading.

Tap zones

Taps where your thumb is.

Four tap-zone layouts: classic sides, forward-anywhere for one-handed reading, an L-shaped layout, or off entirely for swipe-and-volume-key purists. Same zones in both reading modes.

Hardware

Volume-key page turns.

Volume up scrolls up, down scrolls down — off by default. Audio focus is handled properly, so calls and podcasts behave normally when you're not in the reader.

Collections

A library that stays sorted.

Categories you define, an updates feed for ongoing books, grid or list views, and a home screen that knows what you were reading and how far you got — down to the paragraph.

Portability

Backup & restore, one file.

Everything — library, history, bookmarks, highlights, codex, settings — exports as a single ZIP, automatically on a schedule if you like. New phone, one import, done.

No catch

Free, and it stays that way.

Appendix · honest answers

The honest FAQ.

Is it really free?
Yes. Free to download from GitHub Releases — no subscription, no ads, no in-app purchases. And since the source is right there, you can see exactly what it does.
What is the character codex?
The app scans your downloaded chapters on-device and builds an index of recurring characters, places, and factions — when they first appeared, how often, and every mention with a snippet. It only shows entries up to your current reading position, so it can't spoil you. Tap any mention and the reader opens at that paragraph.
Does the character analysis use the cloud?
No. The codex, the relationship graph, and full-text search all run entirely on your phone. It's fast heuristics and a local index, not an API call. There is no NovelForge server for your reading to reach.
What books can I read in it?
Anything you have as an EPUB, plus plain text and Markdown files — import one and the cover, chapters, and metadata are extracted automatically. You can also add web sources to read from, the same pages your browser would load. NovelForge doesn't host, store, or distribute any content itself, and anything in your library exports back out as a clean EPUB.
Will there ever be an iOS version?
Not planned. An iOS version would mean a separate codebase and a different distribution path, and the focus is on making the Android app as good as it can be.
Can I support the project?
Bug reports, feature suggestions, and code contributions on GitHub are the most useful thing. After that, telling other readers it exists. There's no donation page on principle — if you're feeling generous, support an author whose work you've enjoyed.
Where is my data stored?
Locally, in the app's private storage. Reading history, bookmarks, highlights, codex, settings — all of it. Settings has a one-tap backup that exports everything as a single ZIP; importing it on a new device restores it all.
