TwinMind is a mobile-first “second brain” that listens all day — but its flagship transcription model runs in the cloud and there’s no Windows app, only a waitlist. LUCI is the desktop answer: meetings plus screen memory, 100% on-device, shipping on Mac and Windows today.
Desktop-first life memory for every AI agent: bot-free meeting notes plus screen memory, 100% on-device. Mac & Windows.
Mobile-first always-on listener: ambient audio capture on iOS/Android/Chrome/Mac; best accuracy via cloud model. No Windows app.
TwinMind — built by an ex-Google X team, seed-funded with Sequoia participation — puts an always-on AI recorder in your pocket: it captures ambient conversations on iPhone or Android all day, deletes audio on the fly, and builds a searchable memory from the transcripts. It's an ambitious take on personal memory, and on mobile it has no real equal. But bring it to desk work and the fit breaks down: there is no Windows app (waitlist only), its highest-accuracy Ear-3 transcription runs in the cloud by TwinMind's own description, and it captures only audio — none of what happens on your screen. LUCI starts where your work actually lives: your computer. Meetings and screen activity are recorded, transcribed, and indexed fully on-device on both Mac and Windows, and an agent turns that memory into follow-ups.

Desktop meetings + screen memory + agent, all local. Free forever.
Speaker ID, cloud models (ChatGPT/Gemini/Claude), call recording. Free tier available.
Save the transcripts and notes you need from TwinMind — memory summaries and key conversations first.
Native installers for both platforms — no waitlist. Grant microphone and screen permissions.
LUCI captures your calls bot-free with live local transcription, then adds the screen context TwinMind never saw.
Honest note: LUCI has no mobile app. If ambient mobile capture matters to you, the two can coexist — LUCI owns the desktop, on-device.
Capture every Zoom, Meet & Teams call locally on your device — no bot joins the call — and turn it into searchable notes and action items.
TwinMind is candid that its most accurate speech model, Ear-3, “runs on the cloud” — full offline mode falls back to a smaller on-device model. LUCI doesn’t make that trade: the models that transcribe, summarize, and search your work all run locally, accelerated by your machine’s NPU or GPU.
Knowledge work happens on a computer: meetings on Zoom, decisions in docs, numbers in dashboards. TwinMind hears the audio; LUCI also captures the screen and indexes both into one local memory — and it actually ships on Windows, where TwinMind has only a waitlist.
TwinMind’s pitch is 16-hour always-on listening. Powerful — and the reason its own reviews raise “always-listening” unease. LUCI captures deliberately: you start it for meetings and choose what the screen recorder covers, with everything staying on-device either way.
Both products let you ask questions across past conversations. LUCI goes a step further: its agent drafts the follow-up email, updates the CRM, and files the summary — actions, not just recall.
Partly. TwinMind transcribes with an on-device model and deletes audio on the fly, which is genuinely privacy-forward for mobile. But its flagship Ear-3 model — the one behind its headline accuracy and 140+ language claims — runs in the cloud by TwinMind’s own description, and Pro features route through ChatGPT, Gemini, and Claude. LUCI’s entire pipeline is local.
Not as of mid-2026 — its download page lists iPhone, Android, Mac, and a Chrome extension, with Windows on a waitlist. LUCI ships native apps for both Windows and macOS.
No. TwinMind is an audio-first product (with a Chrome extension for browser-tab context). LUCI records and indexes your whole screen locally, alongside meeting audio, so its memory covers what you saw as well as what you heard.
Yes — arguably the more direct fit. LUCI captures Zoom, Meet, and Teams calls bot-free on your computer with live on-device transcription and 4-hour sessions, then links each meeting to related screen activity. TwinMind’s strength is ambient, on-the-go conversation capture.
LUCI is free and 100% local. TwinMind’s free tier is generous because usage feeds a freemium mobile product. The products optimize for different things: TwinMind for capture volume, LUCI for keeping your entire work memory on hardware you own.
Free on Mac and Windows. Fully local.
