CleverGhost: Smart PDF Library & Toolkit for Mac
Drop in your PDFs. CleverGhost takes it from there.
CleverGhost turns scattered PDFs into a private, organized library you can search and talk to. It reads your documents, extracts important details, finds related files, answers questions, creates citations, removes duplicates, and includes the PDF tools you use every day.

SMART LIBRARY
Add your PDFs and CleverGhost organizes them automatically.
It recognizes research papers, books, theses, invoices, contracts, IDs, medical documents, tickets, bank statements, and more. Titles, authors, dates, document types, and key details are extracted for you.
No endless renaming. No complicated folder system. Just a clean, searchable library.
ASK YOUR PDFS
Search by meaning, not only by filename.
Ask questions in plain language:
* Find papers about amorphous materials
* Which contracts have a notice period under 30 days?
* When does my passport expire?
* Compare the conclusions of these three papers
* Show my recent invoices
Ask about one PDF, a group of documents, or your entire library. CleverGhost combines semantic and keyword search to find information even when you do not remember the exact wording.
FIND RESEARCH
Finder helps you discover papers across your Smart Library and arXiv. Search several topics, explore more results, and import useful papers directly into your library.
RESEARCH ATLAS
See how your documents connect.
Research Atlas turns your library into a visual map of topics, authors, journals, and relationships. Explore recurring ideas and discover connections that are difficult to see in a normal file list.
PRIVATE AI, YOUR CHOICE
CleverGhost is private by default.
Run AI directly on your Mac using Apple’s built-in models or supported local MLX models, including Gemma 4 OptiQ, Mistral Nemo, Qwen Coder, and Qwen 3.6.
Cloud AI is optional. You can connect Google Gemini using your own API key.
Optional online services such as CrossRef, arXiv, Semantic Scholar, HAL, and OpenAlex are used for research and citation metadata.
