## What is Pocket Knowledge?

Pocket Knowledge is an offline knowledge base assistant for iPhone and iPad. Organize PDFs, Word files and notes into a personal library, ask questions about your documents, and check the passages cited in each answer. Keep study notes, work manuals and reference material close at hand.

CREATE YOUR KNOWLEDGE BASE
Import PDF, DOCX, TXT or Markdown files. Review and correct extracted text before creating a library. Scanned PDFs can use on-device text recognition.

ASK OFFLINE, CHECK THE SOURCES
On-device RAG (retrieval-augmented generation) finds relevant passages, then the included model uses them to prepare an answer. Review the cited text to check numbers, conditions and steps.

KEEP YOUR DOCUMENTS LOCAL
Document processing, library creation, search and answers run on your device. Documents, questions and answers are not uploaded to developer servers. No account is required, and the default answer model is included.

MANAGE YOUR LIBRARIES
Organize libraries by topic, see creation dates, switch collections, and import or export compatible packages. Delete libraries you create or import when you no longer need them.

CHINESE AND ENGLISH INTERFACE
Follow your system language or choose Simplified Chinese or English in Settings. Retrieval is primarily optimized for Chinese material; English and cross-language results can vary.

BEFORE YOU START
• Each document must be 100 MiB or smaller. Keep the app open while creating libraries or generating answers.
• Review extracted text from complex tables, multi-column layouts and unclear scans. Large documents need more processing time and memory.
• AI answers can contain errors or omit details; check the original text. Included libraries contain fictional sample material.
