LUCI Desktop is a free Mac and Windows app that records your screen and meetings, turns them into searchable memory on your device, and hands that context to AI agents.
About LUCI Desktop
What Is LUCI Desktop
LUCI Desktop is a free desktop app from Memories.ai that records what happens on your computer and turns it into memory an AI agent can read. It watches the screen, listens to both sides of meetings and calls, and indexes the result on the same machine. Nothing goes to a server.
The gap it fills is easy to see once you count your apps. GitHub, Notion, and Slack have APIs an agent can reach. The WhatsApp thread, the browser tab, the PDF a client sent, the internal tool with no API at all don't. Those make up most of a working day, and they stay invisible to Claude Code, Cursor, or Codex. LUCI records them and lets the agent pull what it needs on its own. That leaves a real gap. Rewind and Recall made searchable screen recording familiar, but both expect a person to open a timeline and scroll.
Three limits decide whether it fits you. The Mac build needs Apple Silicon and macOS 13 or later with 8 GB of RAM; the Windows build runs on Windows 10 x64. It captures this computer only, so your phone and a second laptop stay out of the memory. And the privacy boundary ends where your agent begins: whatever an agent retrieves becomes part of that conversation, and a cloud agent takes it to the cloud.
Getting Started
- Download the installer for Mac or Windows from luci.memories.ai and run it. The app is free and asks for no card.
- Grant screen recording and microphone permissions when prompted. Capture starts only after you approve them and leave LUCI running.
- Pick a local model in settings. Phi, Qwen, Llama, and DeepSeek are offered, and you can switch later without losing existing memory.
- Open Agent access and install the skills into Claude Code, Cursor, or Codex. LUCI finds the agents on your machine and writes into each one's skills folder.
- Work as usual for a day, then ask your agent what you were looking at this morning or where a meeting decision came from.

Key features
Screen memory kept on your machine
LUCI captures what appears on screen, reads it with a vision model, and keeps the index in a local folder. Search is the payoff. It works on exact text or on meaning, so "the pricing table I saw yesterday" can find a page you never bookmarked. The result is on-device memory that survives without a cloud account.
Agent Bridge for Claude Code, Cursor, and Codex
The app detects coding agents installed on your computer and writes three skills into each one: luci for search, distill for the daily record, and summarize-meeting for write-ups. That makes Claude Code memory a record of your actual day instead of one more chat thread. There's no config file to edit and no endpoint to paste. Setup takes minutes. Agents that can't load skills can use the local MCP memory server instead, which is bound to loopback and needs a token tied to your install.
Questions in plain English
You can ask across screen and meeting history in ordinary language. Narrow a query to one app or one time range, or ask where the day actually went and get a breakdown. Calls are logged locally with the volume of data returned, not the search terms, so you can see how much an agent is pulling.
Redaction before anything is saved
Cards, keys, and passwords are blacked out on the computer before the record is written. Password managers and banking apps are excluded by default, and you can opt out per app. The credential never lands in the index.
Local models you can swap
LUCI runs Phi, Qwen, Llama, or DeepSeek on the machine's AI accelerator rather than the CPU, which is what makes all-day capture practical on a laptop. Switching models doesn't move or reset the existing memory. Swap it whenever. None of the inference needs a data center.
Meetings transcribed without a bot
Meeting transcription covers your voice and the other side of the call, and the transcript is attached to the day it happened. No bot joins the meeting. Nobody sees a recorder in the participant list. Turn meeting capture off when you want a gap, and the rest of the screen history keeps recording.
Distill your day into a Life folder
An agent can turn a finished day into a short written record and file it in a Life folder as plain Markdown. What happens if the app is closed? The folder still opens. Those files stay readable even when LUCI isn't running, which gives you a fallback when an agent can't reach the live index. A weekly log or a personal journal becomes a routine rather than a project.
Pros and cons
Pros
- Free with no tier, no trial window, and no usage cap, which is unusual for a screen memory tool.
- Everything runs on the device, including transcription and indexing, so there's no upload step to audit.
- Agent Bridge installs into Claude Code, Cursor, and Codex in a few clicks instead of a manual MCP setup.
- Sensitive fields are redacted at capture time, and password managers are excluded by default.
- The local MCP server is bound to loopback with a per-install token, so a web page can't drive it.
Cons
- Mac support stops at Apple Silicon, so Intel Macs are left out entirely.
- It records one computer only, with no phone capture and no sync between machines.
- Once a cloud agent retrieves a memory, that content leaves your machine and sits in the agent's own conversation.
- There's no cloud backup, so a dead drive means the history is gone unless you copy the folder yourself.
Frequently asked questions
It records your screen and both sides of your meetings, then turns that into a searchable memory stored on your computer. The agent you already use can query that memory, so it knows what you saw and heard without you describing it.
