The Docling Reader processes multiple document formats using IBM’s Docling library. It handles PDFs, documents, presentations, spreadsheets, images, audio, video and markup files.

​
Code

from agno.agent import Agent
from agno.knowledge.knowledge import Knowledge
from agno.knowledge.reader.docling_reader import DoclingReader
from agno.vectordb.pgvector import PgVector

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

# Create a knowledge base with docling reader
knowledge = Knowledge(
    vector_db=PgVector(
        table_name="docling_documents",
        db_url=db_url,
    )
)

# Add documents using DoclingReader
knowledge.insert(
    path="documents/report.pdf",
    reader=DoclingReader(),
)

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

# Query the knowledge base
agent.print_response(
    "Summarize the key findings from the report",
    markdown=True,
)
