Everything Bibliotaph does.

Bibliotaph answers one question: what do I own that would help me prepare or run this session? It catalogs what you already have, where it already is, and finds both the books and the pages inside them.

Getting going

• Add a folder and go. Bibliotaph starts reading at once, and a book is searchable as soon as its text is in, while the rest carry on.
• A tour on the first day points at where to add your first folder and, once your books show, at the parts of the window you'll use. Show the tour again in Settings › Preferences starts it over.
• Settings in four groups, Books, Cataloguing, You and, on the web, Admin, laid out the same on Windows and the web.

Search

• Every page of every book. Words, quoted phrases, OR, -word and word*, with results in two tabs: the books, and the pages inside them, with the words highlighted in the page's own text.
• Fields for everything. type:adventure level:3, one for every detail Bibliotaph keeps, plus favorites, collections, folders and formats, and unknown for what isn't filled in yet. A guide under the search box lists each field's values with how many books have each.
• Filters for game system, type, character level and players, with setting, themes, environments, publisher and edition a click away.
• Ask in plain English. With AI switched on, ask the library or one book a question and get an answer that cites the book and page, one click from the page itself.

Reading and running a session

• A reader for PDFs and e-books with thumbnails, the book's contents, find, page notes, and page numbers that match the printed ones.
• Binders gather books and page ranges in your order, with your notes: a focused set of references or any other pages you want together, stepped through one after another.
• Collections group books around a campaign, setting or idea, and nest. Favorites, saved searches and pins keep what you use close.

A catalog that fills itself in

• Details from what's there: the file's name and folder, the book's own metadata, and its text. Identical files are one book with several copies, and a changed file is a new version of the same book.
• Looked up by ISBN. A book that prints an ISBN is looked up in RPGGeek, Open Library and Google Books, and each detail comes from the first that has it. Only the ISBN, or for RPGGeek the title, is sent. The Windows app asks Open Library, or all three through your web library when it's connected to one.
• Adventures inside a file, such as a collection of short adventures, each found with its own levels and pages.
• Optional AI suggests the game system, type, levels, players, setting and more, quoting the page it found each one on, and throws away anything it can't quote. It can also scan whole books for the setting, environments, themes and creatures in each chapter.
• Needs review shows only what needs you: new values, copies that might be the same book, folders that look like a collection. Your corrections always win, then the catalogues, then the AI, and reading a book again never erases them.
• Lists you control. Game systems, settings, themes and the rest are your own lists, each term with its other names. Terms that look like one thing under two names ("Greyhawk" and "Grayhawk") are offered to combine, with Undo, and the AI can ask before it adds a new name or add it straight away.

Files and storage

• PDF, EPUB, Kindle (MOBI, AZW, AZW3), JPG, PNG and WebP, inside ZIPs too, without unpacking them. Scanned pages are read with text recognition.
• Your files are only ever read. Bibliotaph never moves, renames, edits or deletes them, and knows a file by its contents, so a moved or renamed one keeps everything attached to it.
• On the web: OneDrive, Google Drive, Dropbox, Box and WebDAV servers such as Nextcloud, several accounts of each, with changes noticed within minutes. The server reads each book once and keeps no copy.
• On Windows: any folder, including drives that come and go and OneDrive's online-only files.
• Passwords and protection. A PDF with a password asks for it when opened, and can be made searchable. Bibliotaph never guesses passwords or removes DRM.

Online libraries

• Books you own on D&D Beyond and Demiplane join the library with a link to read them there. Books bought on Humble Bundle and DriveThruRPG are listed with where to download them, until the file is in your library.
• The Send to Bibliotaph bookmark and browser extension send your library page from the service to Bibliotaph in one click, with covers. Nothing is imported until you say so, and Undo takes it back.

AI, your way

• On Windows, a model runs on your own PC, downloaded once, with nothing sent anywhere; or use a model server you already have, such as Ollama or LM Studio.
• On the web, bring your own key for an AI provider. Without one, the server does no AI at all.
• Read every book again from Settings › Processing when you've added names to your lists, so the books that use them find them. Looking up, scanning whole books and finding files run again from there too. Your own values stay as they are.
• Read once, for every device. With a PC connected to the web library, what its AI found in a book is shared by the file's contents, so the same book isn't read again anywhere else.
• Everything else works without AI.

Your data

• Your work is kept apart from what can be rebuilt, so reading books again never touches your corrections, notes, collections or binders.
• Backups on demand and weekly, with the last four kept, and Restore. Export as CSV or JSON.
• Sync. Connect the Windows app to the web library and your work merges both ways, record by record.
• No ads, no tracking, and nothing sold. See the privacy policy.

Windows app and web

The Windows app is free, needs no account, and works offline: everything lives on your PC. It runs on Windows 10 (1809 or later) and Windows 11. Download it.

The web version at bibliotaph.online is for libraries kept in cloud storage, in any modern browser, and installs as an app. It looks and works like the Windows app. Sign in with Google, Microsoft or Discord. It is invite-only for now.

The guide explains how to use each of these, and the full list, with every detail, is in the features document.
