+
+## Project Overview
+
+Cognee is an open-source AI memory platform that transforms raw data into persistent knowledge graphs for AI agents. It replaces traditional RAG (Retrieval-Augmented Generation) with an ECL (Extract, Cognify, Load) pipeline combining vector search, graph databases, and LLM-powered entity extraction.
+
+**Requirements**: Python 3.9 - 3.12
+

+
+## Architecture Overview
+
+### Core Workflow: add → cognify → search/memify
+
+1. **add()** - Ingest data (files, URLs, text) into datasets
+2. **cognify()** - Extract entities/relationships and build knowledge graph
+3. **search()** - Query knowledge using various retrieval strategies
+4. **memify()** - Enrich graph with additional context and rules
+
+### Key Architectural Patterns
+
+#### 1. Pipeline-Based Processing
+All data flows through task-based pipelines (`cognee/modules/pipelines/`). Tasks are composable units that can run sequentially or in parallel. Example pipeline tasks: `classify_documents`, `extract_graph_from_data`, `add_data_points`.
+
+#### 2. Interface-Based Database Adapters
+Multiple backends are supported through adapter interfaces:
+- **Graph**: Kuzu (default), Neo4j, Neptune via `GraphDBInterface`
+- **Vector**: LanceDB (default), ChromaDB, PGVector via `VectorDBInterface`
+- **Relational**: SQLite (default), PostgreSQL
+
+Key files:
+- `cognee/infrastructure/databases/graph/graph_db_interface.py`
+- `cognee/infrastructure/databases/vector/vector_db_interface.py`
+
+#### 3. Multi-Tenant Access Control
+User → Dataset → Data hierarchy with permission-based filtering. Enable with `ENABLE_BACKEND_ACCESS_CONTROL=True`. Each user+dataset combination can have isolated graph/vector databases (when using supported backends: Kuzu, LanceDB, SQLite, Postgres).
+
+### Layer Structure
+
+```
+API Layer (cognee/api/v1/)
+    ↓
+Main Functions (add, cognify, search, memify)
+    ↓
+Pipeline Orchestrator (cognee/modules/pipelines/)
+    ↓
+Task Execution Layer (cognee/tasks/)
+    ↓
+Domain Modules (graph, retrieval, ingestion, etc.)
+    ↓
+Infrastructure Adapters (LLM, databases)
+    ↓
+External Services (OpenAI, Kuzu, LanceDB, etc.)
+```
+
+### Critical Data Flow Paths
+
+#### ADD: Data Ingestion
+`add()` → `resolve_data_directories` → `ingest_data` → `save_data_item_to_storage` → Create Dataset + Data records in relational DB
+
+Key files: `cognee/api/v1/add/add.py`, `cognee/tasks/ingestion/ingest_data.py`
+
+#### COGNIFY: Knowledge Graph Construction
+`cognify()` → `classify_documents` → `extract_chunks_from_documents` → `extract_graph_from_data` (LLM extracts entities/relationships using Instructor) → `summarize_text` → `add_data_points` (store in graph + vector DBs)
+
+Key files:
+- `cognee/api/v1/cognify/cognify.py`
+- `cognee/tasks/graph/extract_graph_from_data.py`
+- `cognee/tasks/storage/add_data_points.py`
+
+#### SEARCH: Retrieval
+`search(query_text, query_type)` → route to retriever type → filter by permissions → return results
+
+Available search types (from `cognee/modules/search/types/SearchType.py`):
+- **GRAPH_COMPLETION** (default) - Graph traversal + LLM completion
+- **GRAPH_SUMMARY_COMPLETION** - Uses pre-computed summaries with graph context
+- **GRAPH_COMPLETION_COT** - Chain-of-thought reasoning over graph
+- **GRAPH_COMPLETION_CONTEXT_EXTENSION** - Extended context graph retrieval
+- **TRIPLET_COMPLETION** - Triplet-based (subject-predicate-object) search
+- **RAG_COMPLETION** - Traditional RAG with chunks
+- **CHUNKS** - Vector similarity search over chunks
+- **CHUNKS_LEXICAL** - Lexical (keyword) search over chunks
+- **SUMMARIES** - Search pre-computed document summaries
+- **CYPHER** - Direct Cypher query execution (requires `ALLOW_CYPHER_QUERY=True`)
+- **NATURAL_LANGUAGE** - Natural language to structured query
+- **TEMPORAL** - Time-aware graph search
+- **FEELING_LUCKY** - Automatic search type selection
+- **FEEDBACK** - User feedback-based refinement
+- **CODING_RULES** - Code-specific search rules
+
+Key files:
+- `cognee/api/v1/search/search.py`
+- `cognee/modules/retrieval/context_providers/TripletSearchContextProvider.py`
+- `cognee/modules/search/types/SearchType.py`
+
+### Core Data Models
+
+#### Engine Models (`cognee/infrastructure/engine/models/`)
+- **DataPoint** - Base class for all graph nodes (versioned, with metadata)
+- **Edge** - Graph relationships (source, target, relationship type)
+- **Triplet** - (Subject, Predicate, Object) representation
+
+#### Graph Models (`cognee/shared/data_models.py`)
+- **KnowledgeGraph** - Container for nodes and edges
+- **Node** - Entity (id, name, type, description)
+- **Edge** - Relationship (source_node_id, target_node_id, relationship_name)
+
+### Key Infrastructure Components
+
+#### LLM Gateway (`cognee/infrastructure/llm/LLMGateway.py`)
+Unified interface for multiple LLM providers: OpenAI, Anthropic, Gemini, Ollama, Mistral, Bedrock. Uses Instructor for structured output extraction.
+
+#### Embedding Engines
+Factory pattern for embeddings: `cognee/infrastructure/databases/vector/embeddings/get_embedding_engine.py`
+
+#### Document Loaders
+Support for PDF, DOCX, CSV, images, audio, code files in `cognee/infrastructure/files/`
+
+## Important Configuration
+
+### Environment Setup
+Copy `.env.template` to `.env` and configure:
+
+```bash
+# Minimal setup (defaults to OpenAI + local file-based databases)
+LLM_API_KEY="your_openai_api_key"
+LLM_MODEL="openai/gpt-4o-mini"  # Default model
+```
+
+**Important**: If you configure only LLM or only embeddings, the other defaults to OpenAI. Ensure you have a working OpenAI API key, or configure both to avoid unexpected defaults.
+
+Default databases (no extra setup needed):
+- **Relational**: SQLite (metadata and state storage)
+- **Vector**: LanceDB (embeddings for semantic search)
+- **Graph**: Kuzu (knowledge graph and relationships)
+
+All stored in `.venv` by default. Override with `DATA_ROOT_DIRECTORY` and `SYSTEM_ROOT_DIRECTORY`.

+DATA_ROOT_DIRECTORY="s3://your-bucket/cognee/data"
+SYSTEM_ROOT_DIRECTORY="s3://your-bucket/cognee/system"
+```
+
+## Extension Points
+
+### Adding New Functionality
+
+1. **New Task Type**: Create task function in `cognee/tasks/`, return Task object, register in pipeline
+2. **New Database Backend**: Implement `GraphDBInterface` or `VectorDBInterface` in `cognee/infrastructure/databases/`
+3. **New LLM Provider**: Add configuration in LLM config (uses litellm)
+4. **New Document Processor**: Extend loaders in `cognee/modules/data/processing/`
+5. **New Search Type**: Add to `SearchType` enum and implement retriever in `cognee/modules/retrieval/`
+6. **Custom Graph Models**: Define Pydantic models extending `DataPoint` in your code
+
+### Working with Ontologies
+Cognee supports ontology-based entity extraction to ground knowledge graphs in standardized semantic frameworks (e.g., OWL ontologies).
+
+Configuration:
+```bash
+ONTOLOGY_RESOLVER=rdflib  # Default: uses rdflib and OWL files
+MATCHING_STRATEGY=fuzzy   # Default: fuzzy matching with 80% similarity
+ONTOLOGY_FILE_PATH=/path/to/your/ontology.owl  # Full path to ontology file
+```
+
+Implementation: `cognee/modules/ontology/`
+
+## Branching Strategy
+
+**IMPORTANT**: Always branch from `dev`, not `main`. The `dev` branch is the active development branch.
+
+```bash
+git checkout dev
+git pull origin dev
+git checkout -b feature/your-feature-name
+```
+
+## Code Style
+
+- Ruff for linting and formatting (configured in `pyproject.toml`)
+- Line length: 100 characters
+- Pre-commit hooks run ruff automatically
+- Type hints encouraged (mypy checks enabled)
+
+## Testing Strategy
+
+Tests are organized in `cognee/tests/`:
+- `unit/` - Unit tests for individual modules
+- `integration/` - Full pipeline integration tests
+- `cli_tests/` - CLI command tests
+- `tasks/` - Task-specific tests
+
+When adding features, add corresponding tests. Integration tests should cover the full add → cognify → search flow.
+
+## API Structure
+
+FastAPI application with versioned routes under `cognee/api/v1/`:
+- `/add` - Data ingestion
+- `/cognify` - Knowledge graph processing
+- `/search` - Query interface
+- `/memify` - Graph enrichment
+- `/datasets` - Dataset management
+- `/users` - Authentication (if `REQUIRE_AUTHENTICATION=True`)
+- `/visualize` - Graph visualization server
+
+## Python SDK Entry Points
+
+Main functions exported from `cognee/__init__.py`:
+- `add(data, dataset_name)` - Ingest data
+- `cognify(datasets)` - Build knowledge graph
+- `search(query_text, query_type)` - Query knowledge
+- `memify(extraction_tasks, enrichment_tasks)` - Enrich graph
+- `delete(data_id)` - Remove data
+- `config()` - Configuration management
+- `datasets()` - Dataset operations
+
+All functions are async - use `await` or `asyncio.run()`.
+
+## Security Considerations
+
+Several security environment variables in `.env`:
+- `ACCEPT_LOCAL_FILE_PATH` - Allow local file paths (default: True)
+- `ALLOW_HTTP_REQUESTS` - Allow HTTP requests from Cognee (default: True)
+- `ALLOW_CYPHER_QUERY` - Allow raw Cypher queries (default: True)
+- `REQUIRE_AUTHENTICATION` - Enable API authentication (default: False)
+- `ENABLE_BACKEND_ACCESS_CONTROL` - Multi-tenant isolation (default: True)
+
+For production deployments, review and tighten these settings.
+
+## Common Patterns
+
+### Creating a Custom Pipeline Task
+```python
+from cognee.modules.pipelines.tasks.Task import Task
+
+async def my_custom_task(data):
+    # Your logic here
+    processed_data = process(data)
+    return processed_data
+
+# Use in pipeline
+task = Task(my_custom_task)
+```
+
+### Accessing Databases Directly
+```python
+from cognee.infrastructure.databases.graph import get_graph_engine
+from cognee.infrastructure.databases.vector import get_vector_engine
+
+graph_engine = await get_graph_engine()
+vector_engine = await get_vector_engine()
+```
+
+### Using LLM Gateway
+```python
+from cognee.infrastructure.llm.get_llm_client import get_llm_client
+
+llm_client = get_llm_client()
+response = await llm_client.acreate_structured_output(
+    text_input="Your prompt",
+    system_prompt="System instructions",
+    response_model=YourPydanticModel
+)
+```
+
+## Key Concepts
+
+### Datasets
+Datasets are project-level containers that support organization, permissions, and isolated processing workflows. Each user can have multiple datasets with different access permissions.
+
+```python
+# Create/use a dataset
+await cognee.add(data, dataset_name="my_project")
+await cognee.cognify(datasets=["my_project"])
+```
+
+### DataPoints
+Atomic knowledge units that form the foundation of graph structures. All graph nodes extend the `DataPoint` base class with versioning and metadata support.
+
+### Permissions System
+Multi-tenant architecture with users, roles, and Access Control Lists (ACLs):
+- Read, write, delete, and share permissions per dataset
+- Enable with `ENABLE_BACKEND_ACCESS_CONTROL=True`
+- Supports isolated databases per user+dataset (Kuzu, LanceDB, SQLite, Postgres)
+
+### Graph Visualization
+Launch visualization server:
+```bash
+# Via CLI
+cognee-cli -ui  # Launches full stack with UI at http://localhost:3000
+
+# Via Python
+from cognee.api.v1.visualize import start_visualization_server
+await start_visualization_server(port=8080)
+```
+
+## Debugging & Troubleshooting
+
+### Debug Configuration
+- Set `LITELLM_LOG="DEBUG"` for verbose LLM logs (default: "ERROR")
+- Enable debug mode: `ENV="development"` or `ENV="debug"`
+- Disable telemetry: `TELEMETRY_DISABLED=1`
+- Check logs in structured format (uses structlog)
+- Use `debugpy` optional dependency for debugging: `pip install cognee[debug]`
+
+### Common Issues
+
+**Ollama + OpenAI Embeddings NoDataError**
+- Issue: Mixing Ollama with OpenAI embeddings can cause errors
+- Solution: Configure both LLM and embeddings to use the same provider, or ensure `HUGGINGFACE_TOKENIZER` is set when using Ollama
+
+**LM Studio Structured Output**
+- Issue: LM Studio requires explicit instructor mode
+- Solution: Set `LLM_INSTRUCTOR_MODE="json_schema_mode"` (or appropriate mode)
+
+**Default Provider Fallback**
+- Issue: Configuring only LLM or only embeddings defaults the other to OpenAI
+- Solution: Always configure both LLM and embedding providers, or ensure valid OpenAI API key
+
+**Permission Denied on Search**
+- Behavior: Returns empty list rather than error (prevents information leakage)
+- Solution: Check dataset permissions and user access rights
+
+**Database Connection Issues**
+- Check: Verify database URLs, credentials, and that services are running
+- Docker users: Use `DB_HOST=host.docker.internal` for local databases
+
+**Rate Limiting Errors**
+- Enable client-side rate limiting: `LLM_RATE_LIMIT_ENABLED=true`
+- Adjust limits: `LLM_RATE_LIMIT_REQUESTS` and `LLM_RATE_LIMIT_INTERVAL`

+# What You'll Learn in This Tutorial
+
+In this tutorial, you'll learn how to use Cognee to transform scattered data into an intelligent knowledge system that enhances your workflow.
+By the end, you'll have:
+
+- Connected disparate data sources into a unified AI memory graph
+- Built a memory layer that infers knowledge from provided data
+- Learn how to use search capabilities that combine the diverse context
+
+This tutorial demonstrates the power of knowledge graphs and retrieval-augmented generation (RAG), showing you how to build systems that learn from data and infer knowledge.

+# Cognee and Its Core Operations
+
+Before we dive in, let's understand the core Cognee operations we'll be working with:
+
+- `cognee.add()` - Ingests raw data into the system
+- `cognee.cognify()` - Processes and structures data into a knowledge graph using AI
+- `cognee.search()` - Queries the knowledge graph with natural language
