Captures full-screen screenshots at configurable 5-second intervals via Electron's native screen capture APIs, storing raw image files to disk and queuing them for asynchronous VLM processing. The system uses a dedicated screenshot monitor thread that respects display state (active/idle) and integrates with the context capture pipeline to timestamp and batch screenshots for efficient processing without blocking the UI.
Unique: Implements a dual-layer capture architecture where Electron handles raw screenshot acquisition at OS level while Python backend manages async queue and VLM dispatch, decoupling UI responsiveness from processing latency. Uses 5-second fixed intervals rather than event-driven capture, creating a dense temporal record suitable for activity reconstruction.
vs alternatives: More efficient than polling-based screen recording tools because it captures only static frames at fixed intervals rather than video streams, reducing storage by 95% while maintaining temporal continuity for context reconstruction.
Processes captured screenshots through configurable VLM services (local or remote) to extract semantic descriptions of visual content, including detected activities, UI elements, text content, and contextual information. The system maintains a pluggable VLM client architecture supporting multiple providers (Doubao, OpenAI Vision, local models via Ollama) with fallback chains and caching of VLM responses to avoid redundant inference on duplicate frames.
Unique: Implements a provider-agnostic VLM client with pluggable backends and automatic fallback chains, allowing seamless switching between local models (Ollama), commercial APIs (OpenAI, Doubao), and custom endpoints. Caches VLM responses at the screenshot level to avoid reprocessing identical or near-identical frames.
vs alternatives: More flexible than single-provider solutions because it supports multiple VLM backends with fallback logic, enabling cost optimization (local models for non-critical frames, premium APIs for high-value context) and resilience to provider outages.
Provides a cross-platform desktop UI built with Electron and React, managing application state through a centralized store (Redux or similar) with async middleware for backend API calls. The UI includes dashboard components for viewing summaries/todos/tips, search interface for context retrieval, settings panel for configuration, and real-time notifications for proactive content delivery. Electron main process handles window management, system tray integration, and native OS interactions.
Unique: Implements full-featured desktop UI with Electron and React, including dashboard components for context consumption, search interface for retrieval, and system tray integration for proactive notifications. Uses centralized state management with async middleware for backend API integration.
vs alternatives: More capable than web-only interfaces because Electron enables system tray integration, native notifications, and file system access. More maintainable than native platform-specific UIs because single codebase works across Windows, macOS, and Linux.
Provides a REST API backend built with FastAPI and Python, exposing endpoints for context operations (capture, search, retrieval), consumption management (summaries, todos, tips), and configuration. The backend uses async/await for non-blocking I/O, integrates with background task queues (Celery, RQ) for long-running operations, and maintains SQLite and vector database connections. API is served on localhost:1733 by default with CORS enabled for Electron frontend.
Unique: Implements async REST API with FastAPI and background task queues for long-running operations, enabling non-blocking I/O and decoupled processing. Integrates with SQLite and vector databases for context storage and retrieval.
vs alternatives: More efficient than synchronous REST APIs because async/await enables handling multiple concurrent requests without blocking. More maintainable than monolithic architectures because REST API decouples frontend from backend implementation details.
Defines a unified context schema supporting multiple context types (screenshots, documents, activities, todos, tips, summaries) with common metadata (timestamp, source, type, embeddings) and type-specific fields. The system maintains context type definitions in code and database schema, enabling polymorphic queries that treat different context types uniformly while preserving type-specific information. Context merging logic combines related items (e.g., multiple screenshots of same activity) into higher-level abstractions.
Unique: Implements unified context schema supporting multiple types (screenshots, documents, activities, todos, tips) with common metadata and type-specific fields, enabling polymorphic queries and context merging. Context merging logic combines related items into higher-level abstractions.
vs alternatives: More flexible than type-specific storage because unified schema enables cross-type queries and merging. More maintainable than separate storage systems because single schema avoids duplication and inconsistency.
Tracks user activity by analyzing captured context (screenshots, documents, interactions) and extracting activity records with temporal boundaries (start time, end time, duration). The system maintains a temporal index enabling efficient queries by time range, activity type, and duration. Activity records include metadata (application/document name, activity description, confidence score) and references to source context items.
Unique: Implements activity monitoring by analyzing screenshot context to extract activity records with temporal boundaries, maintaining temporal indices for efficient range queries. Activity records include metadata and source references for traceability.
vs alternatives: More comprehensive than simple time-tracking because it infers activities from visual context rather than requiring manual entry. More flexible than application-level tracking because it works across all applications without integration.
Stores captured context in a dual-database architecture: SQLite for structured metadata (timestamps, activity types, document references) and ChromaDB/Qdrant for vector embeddings enabling semantic similarity search. The system maintains a unified schema across both stores with automatic synchronization, allowing queries to combine structured filters (date range, activity type) with semantic search (find similar activities) in a single operation.
Unique: Implements a dual-store pattern where SQLite maintains structured metadata and temporal indices while vector database handles semantic similarity, with automatic synchronization between stores. This decouples structured queries from semantic search, allowing each database to be optimized independently (SQLite for ACID compliance and temporal queries, vector DB for similarity).
vs alternatives: More capable than single-database solutions because it enables hybrid queries combining temporal/categorical filters with semantic similarity in a single operation, whereas vector-only databases lack efficient structured filtering and SQL-only databases lack semantic search.
Converts text descriptions from VLM analysis and document content into high-dimensional embeddings (768-1536 dimensions) using configurable embedding models (local or remote). The system maintains an embedding client with provider abstraction, supporting multiple backends (Doubao embeddings, OpenAI embeddings, local models via Ollama) with batch processing for efficiency and caching to avoid recomputing embeddings for identical text.
Unique: Implements provider-agnostic embedding client with pluggable backends and automatic fallback chains, supporting both local models (sentence-transformers via Ollama) and commercial APIs (Doubao, OpenAI). Includes embedding caching at the text level to avoid recomputing vectors for duplicate content.
vs alternatives: More flexible than single-provider embedding solutions because it supports multiple backends with cost optimization (local models for non-critical embeddings, premium APIs for high-value context) and enables model switching without full recomputation if caching is implemented.
