Ask your AI anything you saw or heard.
Lumi records and transcribes your screens, system audio and mic on your Mac, so it keeps the slides, charts and names a meeting recorder misses. Your AI agent searches for it and cites the moment each answer came from

How it works
Set up once, then just ask
-
Install
Download the DMG and drag Lumi to Applications. It's notarized by Apple, so it opens like any other app.
-
Grant permissions
Allow Screen Recording and Microphone access, and Lumi starts recording immediately. Stop it from Lumi's window at any time, or set a shortcut in Settings. Transcription runs on device with Apple's built-in SpeechAnalyzer.
-
One-click MCP install
Connect Claude, ChatGPT, Pi or Hermes with one click. No config files to edit.
-
Ask your AI client
Ask in plain words and get answers that cite the moments they came from.
Privacy and control
You stay in control
Your recordings stay on your Mac
Everything Lumi captures is stored on your Mac, in a folder you choose. Your recordings are never uploaded. What leaves your Mac
Your AI sees only what it asks for
Your AI client reads just the moments it needs, the same way it reads your Slack or email.
You choose what it keeps
Turn screen or audio off, pick which displays to record, and delete anything, any time.
What it asks for, and why
Screen Recording and Microphone to capture, Accessibility to know which app you were in, and Speech Recognition to transcribe on device.
Other people on your calls
Lumi records system audio and your mic, so it records everyone on a call. Many places require everyone's consent. Tell people before you record, or stop recording for that call.
