PDF Reader

The PDF Reader processes PDF files synchronously and converts them into documents that can be used with Agno’s knowledge system.

Code

examples/basics/knowledge/concepts/readers/overview/pdf_reader_sync.py

from agno.agent import Agent
from agno.knowledge.knowledge import Knowledge
from agno.knowledge.reader.pdf_reader import PDFReader
from agno.vectordb.pgvector import PgVector

db_url = "postgresql+psycopg://ai:ai@localhost:5532/ai"

# Create a knowledge base with PDF documents
knowledge = Knowledge(
    vector_db=PgVector(
        table_name="pdf_documents",
        db_url=db_url,
    )
)

# Add PDF content synchronously
knowledge.insert(
    path="cookbook/08_knowledge/testing_resources/cv_1.pdf",
    reader=PDFReader(),
)

# Create an agent with the knowledge base
agent = Agent(
    knowledge=knowledge,
    search_knowledge=True,
)

# Query the knowledge base
agent.print_response(
    "What skills does an applicant require to apply for the Software Engineer position?",
    markdown=True,
)
