Inside a Plotiar book
Everything your book needs, layered around the page.
Plotiar is one editor with your whole project inside it. Pull it apart and this is what you find, every layer built around the manuscript.
- 01The pageReal A4 or Letter pages, with the margins and breaks your book will print with.
- 02The deskParts, chapters and every tool in one sidebar, with word counts and goals.
- 03The story bibleEvery character, place and object you name, counted in every chapter.
- 04The planPlot grid, corkboard and flowcharts, linked to your chapters.
- 05The worldMaps, family trees and calendars with your own months and days.
- 06The second readerNotes in the margin on pacing, continuity and echoes. It reads. It never writes.
The story bible
Write a name once. Plotiar remembers the rest.
Characters, places, factions and objects become entries beside your manuscript. Plotiar finds every mention in every chapter and maps who is tied to whom, so chapter twenty never forgets chapter two.
- Your own entry types, fields and tags
- Mentions counted in every chapter
- Relationships, progressions and what each character knows
- Find entries in what you have written already (Pro)
Chapter One of The Aurora Codex. The names The Lighthouse, Elena, the Ridge and Saltmere light up and become entries in the Lore list. Beside them, mention counts by chapter and a web of relationships between six characters.
The world
Draw the world your book lives in.
Maps you draw yourself, family trees that span generations, and calendars with your own months and days. Every place, person and date stays linked to your story bible.
- Hand-drawn maps with pins, routes and layers
- Family trees with marriages and generations
- Calendars with your own months and weekdays
- Idea boards for everything that does not fit yet
A passage from Chapter One names the Ridge, Saltmere, the harbour, the headland and the lighthouse. The map of Saltmere unrolls and each place drops onto it as a pin, then Elena's path lights up. Beside it, the story calendar and the Vance family tree.
The plan
Plan in whatever shape your story takes.
Some books start as a grid, some as a wall of index cards, some as a web of people. Plotiar has all three, linked to the same chapters.
Chapters down, plot lines across. See every thread at once and what still needs writing.

The page
Write on real pages.
Not an endless scroll. Plotiar lays your manuscript out on the page it will print on, with real margins, headers and page numbers, so you always know what your book looks like.

The second reader
It reads your book. It never writes it.
On Pro, Plotiar reads like a sharp first reader. It points out pacing, continuity and echoes in the margin, reviews the whole manuscript, and builds planning tools from what you wrote. The words stay yours.
Pro- Inspect a word, phrase or short sentence for tone, clarity and style
- A full manuscript review, section by section
- Studio builds character bibles, timelines and maps from your chapters
- Your writing is never used to train AI
A reading light moves down Chapter One and three notes appear in the margin, level with the sentences they are about. Beside the page, a manuscript analysis runs its six sections and Studio builds a character bible, a relationship map, a plot grid, a timeline and a continuity bible.

Questions
Before you start.
Yes. Use the Lore story bible with the TTRPG genre template to track NPCs, locations, factions, and items with custom fields. The relationship graph shows how everything connects. Use flowcharts for branching storylines, Maps to draw your world, ideaboards for encounter layouts, and nested folders for session notes.
World Anvil is a wiki-based worldbuilding platform with TTRPG-specific features like interactive maps and player visibility controls. Plotiar is a writing workspace with a structured story bible (Lore) that includes custom types, relationship graphs, and mention detection - plus a full document editor, flowcharts, and interactive maps, all free. On the Pro plan ($12/month) the AI also reads your Lore as context when you brainstorm. If you only need a lore wiki, World Anvil is excellent. If you need to write manuscripts and manage lore in one place, Plotiar does both.
Yes. Maps let you draw your world with layers, routes and pins that link to your Lore entries, and ideaboards give you an infinite canvas for sketches and reference images. Flowcharts let you create structured diagrams for plot arcs, faction hierarchies, timelines, and magic systems.
Yes. On the Plus plan, invite collaborators by email. Everyone works on the same world bible in real time, sees live changes, and can leave inline comments. Only the project owner needs Plus - collaborators join free.
The free plan includes 5 projects with unlimited documents, flowcharts, ideaboards, notes, and tasks. That’s enough for a substantial world. Plus ($5/month) adds unlimited projects, collaboration, and advanced exports.
Yes. Lore is a dedicated story bible built into every project. Create custom types (Characters, Locations, Factions, Magic Systems - whatever your world needs) with configurable fields, colors, and icons. Connect entries with labeled relationships and visualize them in an interactive graph. On the Pro plan, the AI reads your Lore as context when you brainstorm, so it knows your characters - Lore itself is free, the AI integration is part of Pro. Genre templates for Fantasy, Sci-Fi, Thriller, Romance, Academic, and Tabletop RPG get you started in seconds.
Free and Plus give you the entire worldbuilding stack - Lore with custom types and relationship graphs, mention detection, interactive Maps, Family Trees, Flowcharts, and Calendars. Pro ($12/month) is optional and adds AI tuned for worldbuilders: Brainstorm Chat with your Lore injected automatically (so the AI knows your characters and factions), and AI Studio generators including World Bible, Magic / Power System Map, Faction & Organization Map, and Family Lineage. Includes roughly $2.50/week of AI usage.
Free plan includes TXT, DOCX and Fountain. Plus adds PDF and EPUB - so you can export your world bible, campaign notes, or manuscript as polished documents to share with collaborators or publishers.
Yes. Cancel from your account settings whenever you want. Your projects remain accessible on the free plan (limited to five projects). No lock-in, no penalties.
Your book is waiting on the desk.
