LUCI Desktop

Product Introduction

1. Definition: LUCI Desktop is a local-first, on-device AI memory and context capture application for macOS and Windows. It functions as a persistent, searchable memory layer for AI agents, automatically recording screen content, application activity, and meeting audio/transcripts directly on the user's computer.
2. Core Value Proposition: LUCI exists to solve the AI agent context window problem by providing a continuous, private memory of a user's digital workday. It enables AI coding assistants and agents like Claude Code, Cursor, and Codex to access past context—such as forgotten code, meeting decisions, or viewed documents—without manual copy-pasting, thereby creating a truly personalized and context-aware AI experience.

Main Features

1. On-Device Screen & Context Capture: LUCI operates by taking periodic, intelligent screenshots and logging active application windows entirely on the user's device. It uses on-device Optical Character Recognition (OCR) and computer vision models to understand and index text and visual elements without sending data to the cloud. This creates a searchable, chronological record of everything displayed on screen.
2. Local Meeting Transcription & Audio Memory: The app captures system audio to record meetings and calls. Using local speech-to-text models (powered by integrations like Microsoft Foundry Local), it generates transcripts that are time-synced to the daily chronology. A key privacy feature is its "zero-leak redaction," which automatically detects and blacks out sensitive information like passwords and credit card numbers before anything is saved to disk.
3. Agent Bridge & Life Folder Distillation: LUCI's "Agent Bridge" automatically connects to supported AI agents (Claude Code, Cursor, etc.) via protocols like MCP (Model Context Protocol), requiring no manual API configuration. Its "Distill" feature uses a local LLM (options include Phi, Qwen, Llama) to synthesize the day's raw data into a concise, plain-text summary, which is saved as a readable file in a user-owned "Life" folder, ensuring data portability and longevity.

Problems Solved

1. Pain Point: Context Fragmentation and Loss for AI Agents. Traditional AI agents have limited, session-based context windows. Users must manually re-explain past work, re-paste code snippets, or summarize previous meetings, breaking workflow continuity and reducing agent effectiveness.
2. Target Audience: Software Developers & Engineers who use AI coding assistants and need persistent context across projects; Founders & Product Managers who need to track decisions across numerous meetings and documents; Consultants & Researchers who handle multiple clients or topics and require perfect recall of all referenced materials and conversations.
3. Use Cases: A developer can ask their AI agent, "What was the error trace I was looking at an hour ago?" and the agent queries LUCI for the answer. A product manager can get a weekly recap auto-generated from all meeting transcripts. A consultant can have an agent pull specific client constraints mentioned in a call weeks prior while drafting a proposal.

Unique Advantages

1. Differentiation: Unlike cloud-based activity trackers or note-taking apps, LUCI is fully local and private, with no data leaving the device. Unlike manual note-taking or session-specific AI tools, it provides automatic, continuous, and integrated memory for multiple AI agents simultaneously without per-app connectors.
2. Key Innovation: The integration of zero-configuration, on-device context capture with automated agent bridging. By solving capture at the OS/screen level and indexing locally, it bypasses the need for countless SaaS API integrations (OAuth, connectors) while delivering captured context directly into the workflow of the AI tools developers already use.

Frequently Asked Questions (FAQ)

1. Is LUCI a screen recorder that sends data to the cloud? No, LUCI is a fully local desktop application. All screen capture, audio processing, transcription, and AI model inference occur directly on your Mac or Windows PC. Data is encrypted at rest on your disk and is never sent to external servers.
2. How does LUCI work with AI agents like Cursor and Claude Code? LUCI uses the Model Context Protocol (MCP) and similar frameworks to establish a local connection with compatible AI agents. Once installed, it automatically makes your indexed memory available to these agents as a searchable context source, with no API keys or configuration required.
3. Does LUCI work with all my applications, including internal tools? Yes. Because LUCI captures and understands content directly from your screen using OCR and computer vision, it works with any application—web apps, desktop software, terminal, code editors, and even proprietary internal tools—without requiring specific integrations or API access.
4. What are the system requirements for running LUCI Desktop? LUCI requires macOS 13 (Ventura) or later, or Windows 11 or later. It requires sufficient storage for daily memory logs and a capable CPU/GPU for efficient on-device model inference for transcription and analysis.
5. Can I delete my data from LUCI? Yes, you have full control over your data horizon. You can configure retention periods, and deleting a day's memory removes it entirely from your local device. Your "Life Folder" summaries are stored as plain text files you can manage or delete like any other file.
