For novelists who plan
Ink Fortress is a writing workspace that remembers every character, location, and thread across an entire series. Plan on a visual canvas. Write in a calm editor that knows your cast. Edit in five passes. Let the workspace catch the contradictions you'd miss. Then turn your series into a branching adventure your readers play in a free Kindle-like reader.
Story Graph is free forever. No credit card. No expiry.
From plot card to chapter. One click.

You didn't sign up to be a project manager. But somewhere between the first draft and the third revision, your story turned into a logistics problem.
You're paying hundreds of dollars a month for tools that don't talk to each other, and spending half your writing time copying text between them. We're proposing something simpler.
Story Graph · The planning canvas
Most plotting tools were built for a single book. Story Graph treats series as native. Books are nodes. Plot threads cross between them. Scenes attach to characters. Reveals connect back to their clues.
One thread, three books, every connection visible — on an infinite canvas, free forever, yours to keep whether or not you upgrade.
The best writers plan backwards. Define the reveal. Place the clues. Weave the threads.
One thread, three books, every connection visible.
Every alliance, betrayal, and grudge — mapped.
He resents her. She has already forgiven him. Relationships have direction.
Relationship Graph · Character network
Plot is what your characters do. Story is what they become. The Relationship Graph maps every character against every other — alliances, rivalries, secrets, betrayals — across the entire series.
When Sarah lies to Marcus in Ch. 4, the graph remembers. When that lie surfaces in Ch. 19, you'll see it coming because you set it up here.
Plot wants, fears, wounds, and beliefs on one canvas. Build the cast. The story follows.
The Editor · Chapter-organised writing
Distraction-free Tiptap editor with proper chapter and scene organisation in the sidebar — the way Atticus or Scrivener handle structure, but inside the same canvas as your plan. Click a plot card in Story Graph; the chapter opens. Click a chapter; it sits next to its node on the graph.
Type @Sarah and the cast you've built drops in. Hover any mention — voice, traits, last appearance, all there.
The Fortress · Series memory
Locations, factions, items, organisations, lore — the Codex is one place for everything in your world. Build a place once; it appears everywhere it's mentioned, with the right details, every time.
Series-wide knowledge base. Auto-built manuscript bible. The character you named in Book 1 still has the same eye colour, the same scar, the same backstory in Book 3. The vault that was empty in chapter 4 doesn't mysteriously contain a map in chapter 19.
Continuity Hub · The catches you'd miss
Every chapter you write is checked against the Fortress in real time. The character who's allergic to peanuts in Book 1 doesn't order pad thai in Book 2. The vault that locked from the outside in chapter 4 doesn't open from the inside in chapter 19.
Series-wide contradiction detection. You see a flag the moment the inconsistency lands — not in the third revision after your beta readers find it.
Continuity flag · Ch. 19
In Ch. 4, the vault was described as locked from the outside, key held by Marcus. Here, Sarah lets herself out without explanation. Want to reconcile?
Continuity flag · Ch. 12
Eliza died 2020in her Codex profile. Here she's referenced as "still teaching last spring." Want to update one?
Adventure Builder · Your world, now playable
You spent five books building a world your readers love — or five years writing tabletop modules your players still talk about. Ink Fortress turns that material into playable solo reading: choices, consequences, clues, inventory, and scenes that read like fiction instead of dry room notes.
Take the smuggler from book two. Drop her into The Saltmarsh Crown— she chooses her allies, double-crosses the ones she likes, and carves out a kingdom you never wrote. Every reader's version is theirs alone.
Your lore is already loaded. The Adventure Builder pulls the characters, creatures, locations, and history out of your Fortress and into the adventure — nothing to retype.
Your old modules are not stranded. Import a tabletop RPG adventure from 5e, Pathfinder, VtM, Call of Cthulhu, or almost any system, and Ink Fortress turns it into a solo, GM-less reading experience.
They make world-changing choices. Face the factions you created, pick a side, win a throne or lose everything.
Your canon never moves. Readers play inside an instance of your world. Ten thousand readers can each end up on a different throne — your main series stays exactly as you wrote it.
No saga required. Skip the world-building and start a standalone adventure on a blank canvas. The world tools are there when you want them, gone when you don't.
Your canon stays safe. Your world becomes theirs to play in.
Your IP · More than books
Your world is the real asset — a novel is just one way to sell it. Build it once; cash in again and again, to the fans who already love it.
You already did the hard part — building a world people love. Sell it more than once.

Adventure Builder · No code
Start from a blank canvas, your existing series lore, or an imported RPG module. Lay scenes on a map, draw choices between them, and let the engine help translate module notes into vivid, consequence-driven solo prose. What a reader can do next depends on what they've discovered, earned, carried, lost, or chosen.
Import an existing module. Bring in a 5e dungeon, a VtM chronicle, a Pathfinder scenario, or a system-neutral PDF and let the engine convert rooms, encounters, clues, and outcomes into playable scene cards.
Make boxed text worth reading. Instead of flat module prose like “you enter the room and see two guards,” Ink Fortress uses the module's tone, threat, factions, and prior context to draft a vivid solo scene.
Carry an artifact. Your reader finds the skeleton key in room two; at the locked gate forty pages later, only key-holders get through.
Run a quest. Gather the 7 Gems of Vorlon — scatter them across the branches; the final path opens only when the set is complete.
Count what matters. 7 romance points. 3 wattle seeds. Cross a threshold, unlock a new ending. Choices add up — and pay off.
Stay in control. Imported modules land as drafts. You revise, approve, playtest, and publish only when the experience feels right.
Coming soon — the Fortress Game Engine, powered by Core6. We're building in the Core6 universal gaming system — fast d6 dice pools, one-roll combat, and heroes ready in minutes, flexible across any genre. Real RPG mechanics — character stats, skill checks, dice, and combat — drop straight into your adventure with zero code.

Voice memory · AI that sounds like you
The workspace builds a voice fingerprint from your prose — sentence length, cadence, comma habits, the words you avoid, the words you reach for. When the AI offers an alternative line or a Show-Don't-Tell pass, it writes in your voice, not a generic one.
And it never publishes anything on its own. Every suggestion sits next to your prose, awaiting your nod. Accept, refine, reject. You're still the author.
Unlimited · The publishing team
Pro gives the book an editor, public pages, and a storefront. Unlimited is what happens after the buy button exists: launch, marketing, publicity, ARC, reader operations, and audiobook production. Hire that team and you're spending thousands per release.
Your Pro editor stays with you. Unlimited adds the career team around the book, all working from one manuscript memory.
Aimee ·
The Editor
Included in Pro for capped manuscript reads; uncapped on Unlimited. Flags plot holes, character inconsistency, arc collapses, then walks developmental → structural → line → copy → proofreading in order.
Drew ·
The Launch Coach
Owns the calendar. Lines up the publisher platform, ISBN, intro, back cover, launch sequence. Tells you what each coach is doing today, what's slipping, what they need from you.
Carol ·
The Marketing Coach
Builds the marketing system around the Pro storefront. Sets up the first-chapter opt-in and follow-up sequence. Designs the ARC pipeline. Names your reader. Tells you which ad to run, where, with which image.
Chris ·
The Publicity Coach
Writes the press release. Builds the press kit. Drafts your bio, your back cover, your one-line pitch. Identifies the journalists and podcasters who cover your genre — and the angle each will care about.
Allan ·
The Audiobook Coach
Casts voices to your characters. Produces a multi-voice audiobook at Audible quality. Walks you through ACX submission, royalty share vs flat rate, exclusivity. Handles the mastering you didn't want to learn.
One brain
Career team · Shared memory
The team reads from the same manuscript memory the Writer and Story Graph already use. Chris knows what Aimee fixed. Drew knows what Carol shipped. They don't ask you to repeat yourself. No agency briefs. No re-explaining.

They are AI. That's the point.A human launch coach can't read your manuscript by 9am and answer questions about it at 2am. A human launch team can't share a single memory of your book. The reason this offer exists at all is that AI lets us do what humans never could at this price. They cite the chapter so you can check. They never publish anything on their own. You approve every decision.
For grown writers
Sex and violence is part of life. We won't judge.

Drop EPUB, MOBI, or DOCX manuscripts in — Ink Fortress extracts characters, locations, threads, and chapter structure into your fortress. Export the other way whenever you want: manuscripts, knowledge base, story graphs, character profiles — all in standard formats that open anywhere.
