Sorts PDFs by topic, turns pages into flashcards, redacts, and answers questions with the page they came from, all on your Mac. Study on iPhone and iPad too.
Bibliome turns a pile of scattered PDFs and other documents into a library that's genuinely organized — sorted by topic, searchable by meaning, able to find and quote the passages that answer your questions. Everything happens on your Mac.
Point it at your folders and the built-in AI files every document by subject, learning the categories from YOUR collection instead of forcing a fixed list. Research papers are recognized and filed by field with clean titles. Invoices, manuals, receipts, and books each get handled on their own terms.
MORE THAN PDFs
Alongside your PDFs, Bibliome reads Word (.docx), OpenDocument (.odt, .ods), Excel (.xlsx), Rich Text, Markdown, and plain-text files — turn each format on in Settings and the original file is classified, filed, and searched as itself, never converted or copied.
BRING YOUR OLD NOTES WITH YOU
Import an Evernote export (.enex) and choose what comes in, by type, before anything is written. Images and unreadable formats are off by default, damage is named before you commit, stopping keeps what it did, and importing again recognizes what it already brought in. Evernote is a trademark of Evernote Corporation; Bibliome is not affiliated with or endorsed by Evernote.
THE AI LIVES ON YOUR MAC
A full large language model ships inside the app — classification, semantic search, and "Ask Your Library" answers run entirely on your machine, with no Apple Intelligence required. Requires an Apple silicon Mac (M1 or later).
PRIVATE BY CONSTRUCTION
• The app ships without the network entitlement — macOS makes it impossible for Bibliome to open a connection. Not a promise; a property.
• No accounts, no sign-ins, no API keys, no analytics.
• Optional iCloud sync is performed by macOS inside your own Apple account.
TWO WAYS IN, AND THE SAFE ONE IS THE DEFAULT
• Index & Organize reads every document where it already is and organizes it into searchable categories. Nothing is moved or renamed, and you get the whole app with your folders exactly as you left them.
• Auto-File into Folders is there when you do want the filing done for you, and everything it does is reversible.
WORKS WITH YOUR OTHER TOOLS
Bibliome speaks MCP, an open standard — so any tool that supports it (Claude, Cursor, Zed, editor extensions, your own client) can search, ask and cite your documents. It's read-only, there's nothing to install, and answers come from Bibliome itself, so nothing leaves your Mac.
CHOOSE THE MODEL
The bundled model is the default and the one everything is measured on, but you can point Bibliome at another you've downloaded. It checks the folder before trusting it and tells you plainly whether that model has been tested.
A REAL LIBRARY ENGINE
• Ask a question in plain language. Bibliome finds the passages in your own documents that bear on it, cites them, and writes its answer from them — so you can always check the answer against the source.
• Search by meaning or by keyword — even inside scanned documents (built-in OCR, with a depth you control).
• Highlight as you read, in four colors, with notes — and undo takes one back. They are written into the PDF itself, so Preview and other readers see them, and export as text, Markdown, or CSV.
• Mark up a document: pen, arrows, shapes, text boxes, stamps, images, and a reusable signature.
• Redact sensitive content with true rasterization; auto-detect personal info first.
• Merge folders, hunt duplicates, batch-rename cryptic files.
• Page tools, compression, Word-to-PDF, scan-with-iPhone, scheduled overnight runs.
• Smart Groups keep invoices, manuals, and recent additions one click away.
ONE LIBRARY, ALL YOUR DEVICES
The free Bibliome companion for iPhone and iPad lets you read, mark up, bookmark, and file into the same library anywhere — synced through your own iCloud.
One price. No subscription. Your documents never leave your Mac unless you say so.

Seriously impressive

Finally found an app to automatically organize my messy PDFs into topics that actually make sense and love being able to ask questions and get answers from my files while knowing everything stays completely private on my mac.
Developer Response
Thank you. Learning the categories from your own files instead of a fixed list was the hard part to get right, so I am glad they are matching how you think about them.
Great support from the edev

My use case caused some problems with the app at first, but the developer was very responsive - explained why my results weren’t what I expected, updated the app to address the issue and circled back around to check on me. It’s categorizing my documents the way I wanted now, so 2 thumbs up!
Developer Response
Thanks Brian. Glad it is filing things the way you wanted now. The back and forth was genuinely useful, and a couple of the changes that came out of it went to everyone.
A+

It’s the first AI PDF reader that I’d put a confidential document into, because nothing ever leaves the machine. Cites its pages, costs $30 once, and that’s the whole story.
Developer Response
Thank you. Keeping it all on the machine was the whole reason to build it, so it is good to hear that is the part that landed.
Fails to Deliver, Even After Updates

Fantastic concept that has not been implemented here. Library scanning does not work on a basic level, PDFs won’t really be tagged or renamed in any sensible way, and some basic functions like viewing PDFs in the library have bugs that make the library viewer less helpful than the built-in Preview app. I really want this app to work, but it does not.
Developer Response
Thank you for writing this out. Three specific failures is more useful than a rating on its own, and all three point at something I can check.Two of them may be settings rather than bugs, and if so they are fixable today.If you started with Index My Library, that mode is deliberately read only. It builds search and lets you ask questions, and it does not categorize, tag or rename anything. Organize is the mode that files documents. That would explain tagging and renaming doing nothing, and it is my fault for not making that difference obvious at the start.If your PDFs live in iCloud Drive, Dropbox or Google Drive with storage optimization turned on, any file still stored online only is skipped during scanning, silently. Part of your library would be missing from search with nothing telling you it happened. Setting that folder to stay downloaded and running the scan again fixes it.Scale is the third possibility and that one is a real limit rather than a setting. The largest library I have measured against is about 5,000 documents. Above that I do not have data, and I would rather say that than guess.On the viewer, tell me which parts broke for you and I will fix them. That one I do not want to explain away.info@psychosonicconsulting.com if you are willing. I would like to get it working for you either way, and if it does turn out to be one of the settings above, I would appreciate another look at the rating.
study cards turn pages of a pdf into flashcards. choose the pages, and the on-device ai writes question and answer cards and fill in the blank cards, each linked to the page it came from.
study them on your mac. with icloud sync on, your iphone or ipad studies the same decks, and one schedule follows you across devices.
edit or delete any card, add your own from a passage you select, and export a deck to anki, csv or markdown.
renaming or moving a document in the library keeps its catalog entry and its ocr text.
a citation's page number is no longer cut off when the file name is long.
the mcp tab in settings has an add to claude button for claude desktop. save the file, then choose install in claude.
other ai apps use one command that points at bibliome. it no longer needs python3 or xcode's command line tools.
if an ai app asks for your library while bibliome is closed, bibliome opens quietly in the background.
folders you hide from search stay hidden from the ai apps you connect, and a change in settings reaches them within seconds.
the mcp tab says when no ai app has asked yet, and updates by itself while it is open.
the list of hidden folders shows each folder's whole path, and a folder you remove can be put back with undo.
the scan page names your newest scan, automatic ones included.
