Everything you've been wondering about Eureka

Eureka is an AI note card — a dedicated piece of hardware (about the size of a credit card) that captures your conversations, transcribes them with 27-language support, and turns them into structured notes, action items, and calendar todos automatically. Think of it as a second brain you can keep in your wallet: it listens, it understands context, and it tells you what to do next.

A phone app records what people said. Eureka turns conversations into action. Concretely: (1) one-touch capture in 0.5 seconds vs. 5+ seconds of unlock-find-app-tap on a phone, (2) a 4-mic array picks up voices from 10 m and separates speakers automatically — phones can't, (3) action items auto-sync to your calendar instead of you copying them into Notion later, (4) every note links to the person you spoke with, so you walk into the next meeting with full context. Phone apps tell you what was said. Eureka tells you what's next.

Both share the same AI engine, 27-language transcription, 64 GB storage, AskAgent assistant, and CRM features. Eureka 2.0 adds: (a) a 0.96" E-Ink screen that shows live recording status, summaries, and battery without opening your phone; (b) a Corner Action Key — a small raised button you can find by feel for 0.5-second flash capture; (c) a physical mic switch on the side that hardware-disconnects either the ambient or bone-conduction mic for true privacy; (d) USB Type-C (vs. magnetic cable on 1.0); (e) gradient color finish with full-glass front. If you mostly record meetings at a desk, 1.0 is enough. If you're constantly moving — sales calls, walking ideas, podcasts — 2.0's instant capture is the upgrade.

Three reasons an app can't: (1) Reaction time — by the time you've unlocked your phone, the moment is gone. A physical button means you start recording in under a second. (2) Audio quality — phones have one tiny mic optimized for speech-against-your-face. Eureka's 4-mic array + bone-conduction sensor pulls clean voice out of crowded rooms from 10 m away. (3) Trust — pulling out your phone in a meeting signals you're distracted. A card sitting on the table signals you're present.

On Eureka 2.0: long-press the main button on the front for 0.5 seconds for meeting/call mode, or long-press the Corner Action Key on the top-right for 0.1-0.2 seconds for flash idea capture. Both give you a haptic buzz so you know it's recording without looking. To stop, press again. On Eureka 1.0: same long-press start, no haptic. Either way, the card stores recordings locally and syncs to your phone automatically over Bluetooth when in range.

Up to 10 meters with usable clarity, depending on room acoustics. The 4-mic array uses beamforming to enhance speech and cancel background noise — in a real test of a 12-person workshop, Eureka pulled out the dominant speakers cleanly while a single-mic device only caught the loudest one. For 1:1 conversations at a desk, audio is studio-grade.

Yes — that's a big part of why we built the 4-mic array. Each microphone captures the room from a slightly different angle; the AI combines them to isolate voices and subtract background hum, traffic, café noise, etc. We tested it at a 60-person dinner event and still got 4% word error rate. A phone app in the same setting was closer to 20%.

Yes. Eureka uses voice-print recognition (speaker diarization) to auto-label different people in the transcript. The first time someone speaks you label them once; after that, Eureka recognizes their voice across all future recordings and links the meeting to their contact profile. Up to ~8 distinct speakers handled reliably in a single recording.

Yes — and that's one of the reasons we built the bone-conduction microphone. Apple blocks software from intercepting call audio, but Eureka's bone-conduction mic picks up vibrations through contact with your ear/jaw when you hold the card near your phone. The audio is captured by Eureka, not the iPhone, so it's fully legal and doesn't require any iOS workaround. Both 1.0 and 2.0 support this.

Two jobs: (1) record iPhone/Android calls when you hold the card to your ear, and (2) cleanly separate your own voice from the room. Because it picks up vibrations through your jaw/sternum, it can recognize you with near-zero error — even in a loud meeting where you'd be impossible to distinguish from the noisiest person at the table by volume alone.

Maximum privacy. The physical slider on the right side hardware-disconnects either the ambient (environment) mic or the bone-conduction (your-voice) mic by cutting its power supply at the circuit level. It's not a software toggle that an app could override — it's a real switch. Useful when you only want to record one side of a conversation, or when you need provable, audit-grade privacy.

Yes — through the companion app. Photos taken during a recording get timestamped and auto-attached to that meeting's notes, so a whiteboard photo or a business-card snap stays in context with the conversation it relates to.

10 system UI languages, 18 ASR (transcription) languages, and 138 translation languages. Major dialects are also handled — Cantonese, Mandarin variants, regional Spanish, etc. You don't need to specify the language before recording; Eureka auto-detects.

In our 30-day test under realistic conditions: 4.1% word error rate (WER) on a normal meeting, climbing to ~5% in noisy environments. For comparison, professional human stenographers typically hit 2-4% WER on clean audio. The accuracy comes from the 4-mic array delivering clean input before transcription even runs.

We use a stack of best-in-class models depending on the task: GPT-5.4, Claude Sonnet 4.5, and Gemini 3 Pro are all selectable for different jobs. AskAgent (our in-house agent layer) coordinates them, picks the right model for each step, and adds web search + retrieval. You don't need to know any of this — you just ask and Eureka handles routing.

Yes — all three are automatic. After a recording, Eureka produces: (1) a structured summary with key decisions and quotes, (2) an action-items list with owner + deadline where mentioned, (3) on-demand: a PPT deck or a deep-analysis report generated from the transcript. There are 300+ pre-built templates (sales-call recap, research interview, lecture notes, etc.) and you can save custom ones.

AskAgent is the AI assistant baked into the app. It has expert knowledge across multiple domains, can search the web for fresh info, and generates professional-grade reports based on your meeting content + external data. Practical example: after a vendor call, ask 'compile a competitive comparison of this vendor and the top three alternatives' — AskAgent pulls public pricing, feature lists, and analyst quotes and gives you a report you can hand to your boss.

Speaker diarization + your contacts. The first time a person speaks, you tag them; after that, Eureka recognizes their voice in any future recording and auto-attaches the meeting to their contact card. When you open a contact, you see every conversation you've had with them, every commitment they made, every action item they own. Walking into a re-meet, you have full context in 10 seconds.

Yes — that's actually how most sales teams use it. Each contact accumulates: meeting history, action items, photos, notes, and AI-extracted summaries ("this customer cares about latency more than price"). It's not a replacement for Salesforce or HubSpot if you need pipeline reporting, but for the relationship intelligence layer — what you said, what they said, what's next — it's better than any CRM because it captures everything automatically.

Yes — global semantic search across every recording, photo, and note in your knowledge base. Search by content ("what did the client say about pricing in Q1?"), by person, by date, or by tag. Files are auto-categorized and archived to a single library.

Eureka 1.0 / 2.0: up to 30 hours of continuous recording, or 5+ days of normal use (intermittent recording + standby). Charges fully in about 1 hour via Type-C (2.0) or magnetic cable (1.0).

64 GB local storage on both 1.0 and 2.0. That's roughly 600 hours of compressed audio — enough that you won't run out before the daily Bluetooth sync moves files to your phone/cloud anyway.

Quick glances without unlocking your phone: recording status (live waveform + timer), battery + Bluetooth state, current mic mode (ambient vs. bone-conduction), and sync progress. After a meeting, you can see the top-3 action items the AI extracted, right on the screen. Useful when you're between back-to-back meetings and don't want to dig through an app.

A small raised button on the top-right of Eureka 2.0. It's the flash-capture trigger — long-press for 0.1-0.2 seconds and Eureka starts recording, optimized for the moments where you'd never have time to pull out a phone (walking down a hallway, driving, mid-conversation). The raised shape means you can find it by touch alone, eyes-free. A single short tap mid-recording drops a timestamp marker you can jump to later.

Eureka 2.0 uses standard USB Type-C — the same cable as your phone, AirPods, MacBook, etc. Eureka 1.0 uses a custom magnetic cable that ships in the box. Both fully charge in about an hour.

Force restart with the reset pinhole next to the Type-C port on Eureka 2.0 — push in a SIM-card pin and hold for 3 seconds. Device reboots, all recordings preserved (they're written to flash storage as they're captured, not held in memory).

Yes — recording is fully offline. The card has its own storage and processes audio locally. Cloud sync, AI summary, and AskAgent need internet (via your paired phone or PC), but the capture itself works in airplane mode, at 35,000 feet, in a basement, anywhere.

Recordings are stored locally on the card by default. They sync to your paired phone via Bluetooth, and only upload to our cloud if you enable cloud backup. Even with cloud enabled, you control retention (30 days / 1 year / forever) and can delete any file in one tap — both from your devices and our servers.

Yes. At rest: AES-256 encryption on the device and in our cloud. In transit: TLS 1.3 between device, phone, and cloud. Enterprise plans add per-tenant key management — your team's data is encrypted with keys we can't access.

Yes. One tap in the app deletes a recording from your device, your phone cache, and our cloud (if synced). Within 24 hours, the file is purged from backups too. For enterprise users, audit logs prove deletion happened.

Enterprise plans are SOC 2 Type I certified with documented EU data residency (storage in Frankfurt). The on-device-first architecture means most cross-border transfer issues don't apply by default — audio doesn't leave the device unless you turn on sync. We're happy to walk your security/legal team through the architecture; email contact@eurekamind.ai.

Native apps for iOS, Android, macOS, and Windows. There's also a web app for transcription review and document generation. All four sync to the same account — start recording on the card, review on your laptop, generate a PPT on your phone.

Yes — when Eureka extracts an action item with a date attached ("let's review this on Thursday"), it can auto-create the calendar event in Google Calendar, Apple Calendar, or Outlook. You approve the first one, and then it remembers your preference and runs autopilot.

Notion + Slack export shipping in Q3 2026; Salesforce, HubSpot, and Pipedrive integrations are on the roadmap for late 2026. Today you can export transcripts and summaries as TXT/PDF/DOCX/Markdown and drop them anywhere.

Single press on the front button — the screen lights up and Eureka starts broadcasting Bluetooth. Open the EurekaMind app on your phone, tap "Pair new device," and confirm. Takes about 15 seconds. After the first pair, the card auto-connects whenever it's in range.
