Markdown Chunking

Markdown chunking splits Markdown documents while preserving heading structure and hierarchy. It respects Markdown syntax to create chunks that align with document sections, keeping headings with their associated content.

Code

import asyncio
from agno.agent import Agent
from agno.knowledge.chunking.markdown import MarkdownChunking
from agno.knowledge.knowledge import Knowledge
from agno.knowledge.reader.markdown_reader import MarkdownReader
from agno.vectordb.pgvector import PgVector

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

knowledge = Knowledge(
    vector_db=PgVector(table_name="recipes_markdown_chunking", db_url=db_url),
)

asyncio.run(knowledge.add_content_async(
    url="https://github.com/agno-agi/agno/blob/main/README.md",
    reader=MarkdownReader(
        name="Markdown Chunking Reader",
        chunking_strategy=MarkdownChunking(),
    ),
))
agent = Agent(
    knowledge=knowledge,
    search_knowledge=True,
)

agent.print_response("What is Agno?", markdown=True)

Usage

1. Create a virtual environment

   Open the Terminal and create a python virtual environment.

   Mac

   python3 -m venv .venv
   source .venv/bin/activate
   

2. Install libraries

   pip install -U sqlalchemy psycopg pgvector agno
   

3. Run PgVector

   docker run -d \
     -e POSTGRES_DB=ai \
     -e POSTGRES_USER=ai \
     -e POSTGRES_PASSWORD=ai \
     -e PGDATA=/var/lib/postgresql/data/pgdata \
     -v pgvolume:/var/lib/postgresql/data \
     -p 5532:5432 \
     --name pgvector \
     agno/pgvector:16
   

4. Run Agent

   Mac

   python cookbook/knowledge/chunking/markdown_chunking.py
