Your Bible Got Bigger Than the Book.
Three continents, nine factions, a magic system with actual rules, and somewhere in there is also a novel. Ishvana is the writing studio that treats that as the normal state of things. Your lore, your entities, your manuscript, in one desktop app on your own machine.
Five Tabs, One Book, No Continuity
A Google Doc for the manuscript. A Notion database for the lore. A separate wiki for the magic system. Pinterest for references. A calendar app for the timeline. Grammarly for the prose. None of them talk to each other, and your Duke dies in chapter three of book one and shows up alive in chapter eight of book five.
- Scattered State
- Your lore lives in one tool. Your prose lives in another. Manually copying entity details between apps is slow and error-prone, and nothing checks consistency for you.
- No Entity Awareness
- Generic writing tools don't know that "Aldric" and "Alric" are the same character. They can't color-code a location when you mention it. They can't warn you when a fact contradicts what you wrote in book two.
- No Consistency Net
- The longer the project gets, the harder it is to keep the world straight in your head. Flat files don't catch the Duke's birth year drifting by forty years between book one and book four. Lorekeeper does.
- The Subscription Tax
- Five tools means five subscriptions. By year two you're paying $500+ a year for a writing stack that still requires you to do the copy-pasting between apps yourself.
Every Worldbuilding Tool You Actually Need
Most writing apps bolt a notes sidebar onto a word processor and call it worldbuilding. Ishvana starts from the opposite side. The studio is built around your lore first, and the editor plugs into it.
Twelve entry types with fields tuned for each one. Every detail structured, every entity linked to every other.
Legendry Database
Twelve entry types: characters, locations, factions, items, events, concepts, species, languages, religions, legends, articles, and custom. Each type has its own fields, because a magic system doesn't have the same shape as a character.
Relationship Graph
Eighteen relationship types, bidirectional, visualized with a force-directed graph. Click any node and traverse the connections. Useful when you've forgotten which faction the Duke's bastard half-sister belongs to.
Interactive Maps
Pins, polygons, polylines, typography labels, scale calibration. Every mark on the map links back to the Legendry entry behind it.
Character Knowledge
Track what each character knows at each point in the story. The matrix view catches a character referencing something they shouldn't know yet, before a reader writes in about it.
Timeline Studio
Custom fantasy calendars with your world's months, seasons, and eras, because 365-day Earth years don't fit every setting. Swimlane views per character, automatic date extraction from prose.
Language Studio
A full conlang workbench. Phoneme inventories, phonotactics, lexicon, grammar rules. Generate words from your phonology, tune them by hand, and keep the ones that sound like the language you're actually building.
The Manuscript Is the Center of the App
The Editor is where your prose and your world meet. Characters, locations, and
factions get highlighted inline as you write. Type @ to pull any
entity from your Legendry into the prose without breaking flow.
- Entity Recognition
- Every character, place, and faction from your Legendry is color-coded inline as you write. Hover for a summary, click to open the entry.
- Slash Commands
- Type
/for quick actions. Headings, callouts, dividers, entity mentions, character sheets. The command palette lives inside the writing flow itself, so you're not breaking out of the prose to click into a side panel every time you want to restructure a paragraph. - Seven-Level Outline
- Series → Book → Part → Act → Chapter → Scene → Beat. The structure a long-form project actually needs once a flat list of files and folders stops being enough.
- Focus & Typewriter Mode
- Strip the UI down to just the prose. Typewriter mode keeps the active line at the center of the screen so your eyes stop chasing the cursor.
TipTap v3 with 27 fiction-focused extensions. Entity recognition, slash commands, bubble menu, real-time word count.
The World Stays Straight Across Half a Million Words
Forty chapters in, the King has had four names. That's the specific failure mode long worldbuilding projects get into, and it's the one Lorekeeper was built to catch. It reads your Legendry and your manuscript and tells you where both versions live, so you can pick one and move on.
Lorekeeper
Consistency checking on every save. Anomaly detection catches continuity errors and slow lore drift across a novel-length project, with severity ratings and cited source passages so every flag is actionable.
Character Knowledge
Track what each character knows at each point in the story. The matrix view catches a character referencing something they shouldn't know yet, before a reader writes in about it.
ProseGuard
Your style rules, applied the same way every time. Scope them per project, per document, per scene, or per character. If a villain speaks in fragments, the villain speaks in fragments.
World Knowledge
Real-world fact-checking against the axioms of your world. If your setting has no copper, it flags the copper kettle before a reader writes to you about it.
Use What You Need. Ignore the Rest.
Ishvana is a studio. The difference from a workflow app is that every module stands on its own. If you just want the editor with entity highlights, that works fine. If you want to go deep on a conlang, the full Language Studio is already there waiting. If you never touch the Mechanics engine, it stays quiet and out of the way.
One purchase buys the whole studio, though, which means you can grow into the tools at your own pace. Your first novel might only need the editor and Legendry. Your epic series down the line will use every feature. Same app, same license, same price.
Questions Fantasy Authors Ask
Can I import my existing worldbuilding from Notion, World Anvil, or Campfire?
Markdown and DOCX import covers most cases. Worldbuilding data from other tools typically exports as structured text that Ishvana can ingest into the Legendry database. For specific tool exports, check the docs or contact support.
I write sci-fi, not fantasy. Is this for me?
Yes. The Legendry is genre-agnostic. Characters, locations, factions, and magic systems map just as well to crews, planets, corporations, and FTL technologies. The twelve entry types are about structure, so the themes you're writing don't matter.
Do I have to use every feature?
No. Ishvana is modular. Use the editor and skip the Mechanics engine. Use Legendry and skip the conlang workbench. The features you don't use don't clutter your workflow.
Do I have to configure a model to use Ishvana?
No. Ishvana is a complete writing studio without touching any of the agent-driven features. Editor, Legendry, Plot, Timeline, Mechanics, Language, Maps, ProseGuard, Lorekeeper, and the publishing pipeline all work on their own. You bring your own API keys only if you want to use Hawken, Chat, or Councils. No keys, no problem.
What happens to my data?
Your data lives on your machine. SQLite database, .docx files on disk, standard exports. No cloud sync, no telemetry, no training on your words. Ishvana runs as a desktop application — there's no server behind it to ship your data anywhere.
What platforms does it run on?
Windows 10 and Windows 11, 64-bit. Ishvana is Windows-only.
