CatchMe

🦞 Makes Your Agents Truly Personal. CatchMe ships as an agent-compatible skill for CLI agents (OpenClaw, NanoBot, Claude, Cursor, etc.). Run CatchMe independently. Your agents query memories via CLI commands only.

🎯 Enrich Your Personal Digital Context

✨ Key Features

📹 Always-On Event Capture

• Event-Driven Recording: No timer or delays - catch mouse actions with crosshair annotation instantly.
• Comprehensive Context: Five recorders track windows, keyboard, clipboard, notifications, and files around mouse actions.

🌲 Intelligent Memory Hierarchy

• Auto-Organization: Raw streams structure into five tiers: Day → Session → App → Location → Action.
• Smart Summaries: LLM summaries at each level, transforming logs into searchable knowledge trees.

🔍 Tree-Based Retrieval

• No Vector Complexity: Skip embeddings and VDBs — our system uses tree-based reasoning for navigation.
• Top-Down Search: LLM reads summaries, selects relevant branches, and drills down to evidence.

🤖 Zero-Config Agent Integration

• One-File Setup: Drop a single skill file into any AI agent for instant integration.
• Immediate Access: CLI-based screen history queries with zero configuration required.

🪶 Ultralight & Privacy-First

• Minimal Footprint: ~0.2GB runtime RAM with efficient SQLite + FTS5 storage.
• Local & Offline: All data stays on your machine with full offline mode via Ollama/vLLM/LM Studio.

🖥️ Rich Web Interface

• Visual Exploration: Interactive timelines, memory tree navigation, and real-time system monitoring.
• Natural Conversation: Chat with your complete digital footprint using natural language.

💡 CatchMe Architecture

CatchMe transforms raw digital activity into structured, searchable memory through three concurrent stages:

🔄 Record → Organize → Reason: Turn digital chaos into queryable memory

Capture. Six background recorders silently track your activity. They monitor window focus, keystrokes, mouse movement, screenshots, clipboard, and notifications.

Index. Raw events auto-organize into a Hierarchical Activity Tree: Day → Session → App → Location → Action. Each node gets LLM-generated summaries. Fast, meaningful recall without vector embeddings.

Retrieve. You ask a question. The LLM traverses your memory tree top-down. It selects relevant nodes and inspects raw data like screenshots or keystrokes. Then synthesizes a precise answer.

🌲 Hierarchical Activity Tree

The Activity Tree is CatchMe's memory core. It provides structured, multi-level views of your digital life. Browse high-level summaries or dive into granular details.

🔍 Intelligent Tree Retrieval

CatchMe skips traditional vector search. Instead, the LLM directly navigates your Activity Tree. This enables complex, cross-day reasoning. Precise evidence gathering from raw activity history.

🧠 LLM Configuration

❗️ Data Privacy Notice

• 100% Local Storage: All raw data (screenshots, keystrokes, activity trees) stays in ~/data/ and never leaves your machine.

• Offline-First Options: Local LLMs (Ollama, vLLM, LM Studio) enable fully offline operation without any cloud dependency.

• ⚠️Cloud Provider Caution: If used, cloud APIs will be used to summarize your daily activities. Untrusted endpoints may expose private data — review data policies of your provider carefully.

📋 Requirements

• Multimodal support: Your model should be able to handle text + images.

• Context window: Make sure the context window of your model exceed max_tokens limits in config.json.

• Cost control: For forced cost control, set limits via llm.max_calls or increase filter.mouse_cluster_gap to reduce summarization frequency.

CatchMe requires an LLM for background summarization and intelligent retrieval. Use catchme init (in Get Started)for guided setup or follow the manual configuration steps below.
