LUCI is the AI screen recorder that remembers your whole day on the computer — what you read, wrote, watched, and shipped — and hands that memory to whichever AI agent you use. 100% local and on-device: captured and stored on your own machine, encrypted at rest. The Rewind alternative built for Mac and Windows.
Every important detail at work passes through one place: your screen. The Slack thread where the launch date was decided, the dashboard with the retention spike, the Figma comment from the head of design, the line in a PDF that changed the roadmap. None of that lives in a single tool. None of it is searchable in any meaningful way. By Friday afternoon, you have already forgotten half of what mattered on Tuesday.
AI screen recorders solve this by capturing the screen and using machine learning to make it searchable. Rewind AI proved the category is real. Microsoft Recall confirmed it by shipping a copy. The problem with the existing options is that they are either platform-locked, send your data to the cloud, or both — exactly the wrong tradeoff for something that watches everything you do.
LUCI is built on the opposite premise. The AI runs against your screen, but the data stays on your machine and is never uploaded to the cloud. Private by design, so security teams can adopt it with confidence. The app works on Mac and Windows. And the memory is searchable — by you and by your AI agents over MCP — so the recording is not a graveyard of video files. It is a working brain you can ask questions.
Memory is only useful if you can reach it. Claude Code, Cursor, Codex, Gemini and the other agents you already run read the same screen memory, so they answer from what you actually saw and did instead of asking you to re-paste it. LUCI connects itself — nothing to set up.
Recordings, transcripts, and the memory index live on your machine, encrypted at rest. Nothing is ever uploaded to the cloud. If you ever quit LUCI, you keep your data — there is no vendor lock.
Ask in plain English: 'show me the email about Q3 budget I read last Thursday' or 'pull up the Figma file with the orange variant.' LUCI returns the exact moment with screenshot, app, and timestamp.
LUCI reads and understands what is on screen, locally, and hears every word in your meetings and calls. The result is structured: which app, which document, who you were on a call with, what you wrote. The video is the source of truth; the index is the way in.
Everything runs on your own device — capture, on-device understanding, and your memory, encrypted at rest. Nothing is uploaded to the cloud, and LUCI can run fully offline. Privacy and security teams pick LUCI for exactly this reason.
Unlike Rewind (Mac only) or Microsoft Recall (Copilot+ PCs only), LUCI ships on both major desktop OSes. Your screen memory follows you across machines.
1. Capture. The desktop app records low-bandwidth video and optional system audio in the background. You choose continuous capture, scoped capture (only certain apps), or manual sessions. Sensitive apps and incognito windows can be excluded in one click.
2. Understand. Frames are processed with on-device video understanding and — when audio is part of the session — speech-to-text. LUCI extracts the app, the document, the people, and the actions you took.
3. Remember. The structured signals join LUCI's memory layer alongside your meetings, notes, and chats. Everything is timestamped, cited, and connected. The result is one timeline of work, not a folder of disconnected recordings.
4. Recall. Search in plain language. Ask for that dashboard, that customer complaint, that snippet of code you saw at 4pm last Thursday. LUCI returns the screenshot, the app context, and the exact moment.
5. Connect. Expose the memory to your AI agents over MCP. Let Claude, Cursor, or any MCP-capable tool pull the week's context, three customer calls, and that Figma review — straight from your device. The screen memory is the input; your agents bring their own output.

A screen recorder that ships your data to someone else's servers is the wrong answer. LUCI is local-first: capture, on-device understanding, and your whole memory all live on your machine, encrypted at rest. The app does not phone home with your content, nothing is ever uploaded to the cloud, and none of it is ever used for model training.
Because everything stays on your device, you don't have to trust marketing copy. Run LUCI with the network off and your recordings still work end to end. Teams in regulated industries — legal, finance, healthcare, defense — are some of LUCI's earliest adopters for exactly this reason.
An AI screen recorder continuously or selectively records what happens on your screen and then uses machine learning to understand the content. Instead of producing a video file you have to scrub through, it gives you searchable text, summaries, and links back to the exact moment something happened. LUCI is an AI screen recorder built for local, private use with a persistent memory layer.
Yes. LUCI is one of the most complete Rewind AI alternatives in 2026. It runs on Mac and Windows, captures screen plus audio plus meetings in one timeline, and keeps everything in a local searchable memory your AI agents can read. Rewind users typically switch to LUCI for cross-platform support and for handing that memory to Claude Code, Cursor, or Codex.
Screenpipe is a screen capture pipeline you have to assemble yourself. Microsoft Recall is locked to Copilot+ PCs and Windows. LUCI is the productized middle ground: a polished app on Mac and Windows that bundles capture, transcription, summarization, and a searchable memory your AI agents can query over MCP — all 100% local, with your data never leaving your device.
Only if you tell it to. LUCI supports always-on continuous capture, session-based capture tied to specific apps or meetings, and one-tap manual recording. You decide what is captured, how long it lives, and which screens or apps are excluded. Everything stays local by default.
All recordings, transcripts, and your entire memory are stored on your own device, encrypted at rest. Nothing is ever uploaded to the cloud, and none of it is ever used for model training.
Yes. Ask LUCI a plain-language question — 'what was that dashboard I looked at on Tuesday with the green retention chart?' — and it returns the exact moment, app, and screenshot, plus any related meeting or note. The recording becomes a queryable memory, not a folder of video files.
Yes. LUCI runs entirely on your device and can run fully offline. Recordings, transcripts, and memory are stored locally and never uploaded to the cloud. This is the main reason privacy-sensitive teams pick LUCI over cloud-based screen recorders.
LUCI records, understands, and remembers everything on your screen — locally.
