Friendzone Lite - AI Memory Capture System#

Overview#

Friendzone Lite is an AI-powered memory capture and organization system that helps you extract, refine, and structure memories from images through intelligent conversation. It transforms images into structured, searchable memories through natural language interaction.

Features#

Image-Based Memory Extraction#

  • Upload images via URL to start memory capture sessions
  • AI analyzes visual content to understand the context
  • Extracts initial memory details from image content

Interactive Memory Refinement#

  • Conversational interface to gather missing details
  • AI asks targeted follow-up questions
  • Progressive refinement of memory information

Structured Memory Organization#

  • When: Date information (YYYY-MM-DD format)
  • Who: People involved in the memory
  • Where: Locations relevant to the memory
  • What: Description of what the memory is about

Completion Tracking#

  • Real-time progress indication
  • Summary generation when details are complete
  • Clear completion status with final memory summary

Architecture#

Core Components#

  • Memory Processing Function: update_memory_details() - AI-powered memory extraction and refinement
  • Session Node: Maintains persistent memory state across interactions
  • Update Walker: Handles user interactions and memory updates
obj Response {
    has follow_up_questions: str;    # Next question to ask
    has summary: str;                # Concise memory summary
    has when: str;                   # Date in YYYY-MM-DD format
    has who: List[str];              # Names of people involved
    has what: str;                   # What the memory is about
    has where: List[str];            # Relevant locations
    has terminate_conversation: bool; # Completion flag
    has show_summary: bool;          # Display summary flag
}

Usage#

  1. Install dependencies: 

    pip install jac-streamlit requests jaclang jac-cloud byllm

  2. Start the Jac Cloud server: 

    jac serve friendzone_lite.jac

  3. Run the frontend: 

    jac streamlit frontend.jac

Usage Workflow#

Step 1: Image Upload#

  • Provide an image URL of a photo containing a memory you want to capture
  • The system supports various image formats (JPEG, PNG, WebP)
  • Images can be from social media, cloud storage, or any accessible web location

Step 2: Initial Analysis#

The AI will: - Analyze the visual content of your image - Identify key elements like people, places, and activities - Generate an initial memory framework - Ask the first targeted question to gather more details

Step 3: Conversational Refinement#

Engage in a natural conversation where the AI will: - Ask specific questions about missing details - Focus on one aspect at a time (when, who, where, what) - Build upon your previous answers - Gradually complete the memory profile

Step 4: Memory Completion#

When sufficient details are gathered: - The AI will indicate the conversation is complete - A comprehensive summary will be generated - All memory details will be structured and stored

Example Memory Capture Session#

Initial Image Analysis#

User uploads: Beach vacation photo with friends

AI Initial Response: "I can see this appears to be a beach scene with several people. To help me capture this memory completely, when was this photo taken?"

Conversational Flow#

User: "This was taken last summer, around July 2024"

AI: "Great! I can see there are several people in the photo. Can you tell me who these people are?"

User: "That's me with my college friends Sarah and Mike"

AI: "Wonderful! Where was this beach vacation? Which beach or location was this at?"

User: "This was at Santa Monica Beach in California"

AI: "Perfect! What was the occasion or what were you doing during this beach visit?"

User: "We were celebrating Sarah's birthday with a beach day trip"

Final Summary#

Generated Memory:

  • When: 2024-07-15
  • Who: User, Sarah, Mike
  • Where: Santa Monica Beach, California
  • What: Beach day celebration for Sarah's birthday

Advanced Features#

Memory Categories#

The system automatically categorizes memories: - Social Events: Gatherings, parties, celebrations - Travel Experiences: Vacations, trips, explorations - Personal Milestones: Achievements, life events - Daily Moments: Casual interactions, routine activities

Context Enhancement#

  • Emotional Context: Captures feelings and atmosphere
  • Environmental Details: Weather, time of day, setting
  • Activity Recognition: Identifies specific actions and events
  • Relationship Mapping: Understands social connections

Quality Assurance#

  • Consistency Checking: Validates logical coherence of memory details
  • Completeness Assessment: Ensures all key aspects are captured
  • Accuracy Verification: Cross-references visual and textual information

Technical Implementation#

Visual Analysis Pipeline#

  1. Image Processing: Loads and preprocesses uploaded images
  2. Object Detection: Identifies people, objects, and scenes
  3. Scene Understanding: Analyzes context and activities
  4. Initial Memory Extraction: Creates preliminary memory structure

Conversational AI System#

  1. Question Generation: Creates contextually relevant follow-up questions
  2. Response Processing: Analyzes and incorporates user answers
  3. Progress Tracking: Monitors completion of memory aspects
  4. Dialogue Management: Maintains conversation flow and coherence

Memory Storage Format#

{
  "memory_id": "unique_identifier",
  "created_at": "timestamp",
  "image_url": "source_image_url",
  "details": {
    "when": "2024-07-15",
    "who": ["User", "Sarah", "Mike"],
    "where": ["Santa Monica Beach", "California"],
    "what": "Beach day celebration for Sarah's birthday"
  },
  "summary": "Comprehensive memory description",
  "conversation_log": ["question_response_pairs"]
}

Customization Options#

Question Templates#

Modify questioning strategies for different memory types:

  • Event-focused: Emphasizes activities and occasions
  • People-centered: Prioritizes social connections and relationships
  • Location-based: Focuses on geographical and environmental details
  • Time-sensitive: Emphasizes chronological and temporal aspects

Analysis Depth#

Configure the level of detail for memory capture:

  • Quick Capture: Basic who, what, when, where
  • Detailed Analysis: Extended context and emotional elements
  • Comprehensive Profiling: Full environmental and social mapping

Integration Possibilities#

  • Photo Libraries: Connect with Google Photos, iCloud, or other services
  • Social Media: Import memories from Facebook, Instagram, or Twitter
  • Calendar Integration: Link memories with calendar events and dates
  • Search Functionality: Build searchable memory databases

Use Cases and Applications#

Personal Memory Keeping#

  • Family Archives: Document family events and milestones
  • Travel Journals: Capture vacation and trip memories
  • Life Documentation: Record personal achievements and experiences
  • Social Memories: Preserve moments with friends and loved ones

Professional Applications#

  • Event Documentation: Corporate events and team building activities
  • Project Milestones: Capture important project moments

  • Life Review: Systematic documentation of life experiences

Troubleshooting#

Common Issues#

Image Loading Problems: - Verify image URL accessibility and format support - Check internet connection and firewall settings - Ensure image file size is within reasonable limits

Conversation Flow Issues: - Provide clear, specific answers to AI questions - If stuck, try rephrasing or providing additional context - Restart the session if conversation becomes inconsistent

Memory Quality Concerns: - Be specific and detailed in your responses - Correct any misunderstandings immediately - Use follow-up sessions to refine captured memories

Friendzone Lite showcases the potential of combining visual AI with conversational intelligence to create meaningful, structured memory systems that preserve and organize life's important moments.
