P.DE.I Framework
Personal Data-driven Exocortex Intelligence
A blank slate that becomes intelligent through YOUR data.
"The framework is universal. The intelligence is in your data."
— Core Philosophy: Data Creates Intelligence
🎯 What is P.DE.I?
P.DE.I is a data-driven AI framework that transforms into YOUR personal coding assistant through YOUR data.
The Core Insight
The code is generic. The magic is in what you feed it.
Generic Framework + Your Data = Your Personal AI
Same P.DE.I Installation:
├─ Developer A's data → AI that codes like Developer A
├─ Developer B's data → AI that codes like Developer B
├─ Company X's data → AI that follows Company X's standards
└─ Your data → AI that works exactly how YOU work
What Makes P.DE.I Different
| Feature | Traditional AI | P.DE.I |
|---|---|---|
| Training Data | Everyone's code | YOUR code only |
| Intelligence Source | Pre-trained model | YOUR data |
| Patterns | Generic | YOUR patterns |
| Style | One-size-fits-all | YOUR style |
| Privacy | Cloud/API | 100% local |
| Customization | Limited | Complete |
| Ownership | Vendor lock-in | You own everything |
Result: An AI that's truly YOURS because it learned from YOUR data.

Key Principle
The AI engine is interchangeable. The intelligence persists in your data.
- Switch from Qwen to CodeLlama? Your patterns remain.
- Upgrade to a better model? Your rules still apply.
- Share the framework? Only the blank slate, not your intelligence.
🚀 Quick Start
Step 1: Install the Framework (5 min)
# 1. Get P.DE.I
git clone https://github.com/YourOrg/PDEI
cd PDEI
# 2. Install Ollama (local LLM runtime)
# Download from https://ollama.com
# Run installer for your OS
# 3. Pull an AI model (your choice)
ollama serve # Keep running
# In new terminal:
ollama pull qwen2.5-coder:3b # Recommended
# OR
ollama pull codellama:7b # Alternative
# OR
ollama pull deepseek-coder:6.7b # Alternative
Step 2: Add YOUR Data (10 min)
# Run P.DE.I
python pdei.py --server
# Open http://localhost:8000
# Index your repositories
/index /path/to/your/code
# Or via web interface:
# Click Upload → Drag & drop your code (.zip or folders)
Step 3: Train on YOUR Patterns (Ongoing)
# Generate code
You: Generate a user authentication module
# Correct mistakes
You: /correct "We use JWT tokens, not sessions"
# Extract the pattern
You: /learn
# The AI now knows: Use JWT for auth
That's it. You now have an AI trained on YOUR data.
📊 Data Types: What Feeds the Intelligence
1. Code Repositories (Primary Data Source)
What it learns:
- Function signatures and patterns
- Naming conventions
- Code organization
- Library usage
- Common patterns in YOUR code
Supported Languages:
- Python (
.py) - C/C++ (
.c,.cpp,.h) - Arduino (
.ino) - JavaScript (
.js,.jsx) - HTML/CSS (
.html,.css) - Any text-based code
How to add:
/index /path/to/your/repos
2. Corrections (Learning Data)
What it learns:
- What you consider wrong
- What you prefer instead
- Your standards and requirements
- Domain-specific rules
How to add:
# After AI generates code:
/correct "Explanation of what's wrong and why"
/learn # Extracts pattern
Example correction cycle:
AI generates: Using print() for logging
You: /correct "We use logging.info() not print() for production code"
You: /learn
AI learns: Rule: "Use logging module, not print()"
Next generation: Automatically uses logging.info()
3. Style Preferences (Implicit Learning)
What it learns:
- Indentation style
- Naming patterns (camelCase vs snake_case)
- Comment style
- File organization
- Constants vs variables
How it learns:
- Automatically from your code
- Through corrections
- From accepted generations (what you don't change)
4. Domain Knowledge (Custom Methodologies)
What it learns:
- Your custom frameworks
- Your design patterns
- Your optimization techniques
- Your testing approaches
- Your deployment strategies
How to teach:
/teach "Rule: All database queries use connection pooling"
/teach "Rule: API responses follow JSON:API specification"
/teach "Rule: Use dependency injection for services"
🎯 The Learning Cycle
Phase 1: Initial State (Blank Slate)
Accuracy: 40-60%
Intelligence: Generic LLM knowledge only
Style: Random/inconsistent
Phase 2: Data Indexing (Knowledge Base)
/index /your/repositories
Result:
- Functions indexed: 100-1000+
- Patterns recognized: Basic
- Accuracy: 60-70% (improves immediately)
Phase 3: Correction Training (Pattern Learning)
1st correction: 60% → 65% (+5%)
5th correction: 65% → 75% (+10%)
10th correction: 75% → 85% (+10%)
20th correction: 85% → 90% (+5%)
50th correction: 90% → 95% (+5%)
Each correction teaches 1-3 new rules
Each rule improves accuracy by 1-5%
Phase 4: Mature Intelligence (Your Personal AI)

What goes to external servers:
- ❌ Nothing (unless you explicitly configure external APIs)
Data Ownership
You own:
- The framework (MIT license)
- Your data (100% yours)
- Your trained patterns (your IP)
- Your corrections (your knowledge)
- Your configurations (your setup)
You can:
- ✅ Use commercially
- ✅ Modify freely

Multi-User Isolation
For teams/organizations:
User A's data → Isolated database → User A's AI
User B's data → Isolated database → User B's AI
Shared data → Shared database → Team AI
No cross-contamination. Each user's intelligence is separate.
🎓 Best Practices
Data Quality = Intelligence Quality
Good Data:
- ✅ Well-written code (clean examples)
- ✅ Consistent patterns (reinforces learning)
- ✅ Documented functions (context helps)
- ✅ Multiple examples (pattern recognition)
Poor Data:
- ❌ Inconsistent code (confuses learner)
- ❌ Minimal examples (insufficient patterns)
- ❌ Undocumented code (no context)
- ❌ Mixed styles (conflicting signals)
Recommendation: Index your BEST code first, add more as quality improves.
Correction Strategy
Effective Corrections:
# ✅ Good: Specific and actionable
/correct "Use async/await instead of .then() for promises"
# ✅ Good: Explains the why
/correct "Database connections must use connection pooling to prevent exhaustion"
# ❌ Poor: Too vague
/correct "This is wrong"
# ❌ Poor: No explanation
/correct "Fix it"
Correction Frequency:
- Start: 5-10 corrections per session
- Mature: 1-2 corrections per session
- Goal: Teach patterns, not fix every detail
Incremental Training
Week 1:
- Index your best 10-20 repositories
- Make 10-15 corrections
- Focus on major patterns
Week 2:
- Add more repositories
- Make 15-20 corrections
- Refine style preferences
Week 3:
- Add domain-specific code
- Make 10-15 corrections
- Train on edge cases
Week 4+:
- Maintain with occasional corrections
- Add new patterns as they emerge
- Refine accuracy to 90%+
