Hardware · Ambient Memory
AI memory just grew ears for real conversations.
AI memory has always assumed you were sitting in front of a screen — chats, meeting apps, browser tabs. That assumption just broke. As an extension of its "SecondBrain" memory layer, Genspark launched SecondBrain Note, a card-sized AI voice recorder starting at $179. Press once, and the conversation is recorded and folded straight into SecondBrain's searchable memory.
Why a "recording device," now
Chatbots and browser extensions could only remember what happened on a screen.
Genspark has offered SecondBrain as software that remembers across browser activity and documents. But conversations that happen off-screen — sales meetings, interviews, small talk — have always sat outside that memory. At its "AI Workspace 6.0" launch event, held in Tokyo, the company unveiled SecondBrain Note as its first hardware product built to close that gap. Per the official announcement, AI Workspace 6.0 was restructured around SecondBrain (memory layer), Super Agent (execution layer) and GenTeam (collaboration layer), and SecondBrain Note is the first move to add a voice channel to that memory layer.
The device is a 2.95mm-thin, 26g card priced at $199 (with a $179 launch price). Genspark's own X post introduced it as "your second brain, in a card," emphasizing that it's slim enough to live in a wallet or card case. This isn't a vague "some vendor shipped a new product" story — the notable part is that a company chose hardware, not software, to solve the problem of treating conversation itself as a log.
| Before (screen assumed) | SecondBrain Note (in-person included) |
|---|---|
| Only chat/meeting-app conversations became memory | In-person meetings, small talk, and calls become memory too |
| Notes taken by hand, or transcribed after the fact | One press records; syncs to SecondBrain automatically |
| You had to decide on the spot whether to log it | Carry it always; press it only when it matters |
What the specs reveal about intent
A 4-mic array plus a bone-conduction sensor are built to catch both in-person talk and phone calls.
A 4-microphone array with AI beamforming is said to separate voices from up to 5m away, and during calls a bone-conduction sensor detects the phone speaker's own vibrations directly, capturing the other party's voice too. According to reporting on the specs, the 64GB of onboard storage clears itself automatically once synced to SecondBrain, working out to roughly 7,000 hours of audio capacity. Recordings are said to be encrypted in transit and processed on a security stack certified to SOC 2 Type II and ISO 27001.
Using it is just a press
Attach it magnetically to your phone's back or a card case, then press and hold for 2 seconds to start recording.
Attach it
Clip it to the back of your phone magnetically, or carry it in the included MagSafe-compatible wallet.
Record
Press and hold for 2 seconds to start. Works for in-person meetings and pitches, and the bone-conduction sensor also picks up the other party's voice on calls.
It becomes memory
The recording syncs to SecondBrain automatically, then flows through transcription and summarization straight into meeting notes, tasks, or email drafts.
Who this actually changes things for
The more your job depends on in-person listening, the bigger the payoff.
Sales & deal-making
Every in-person pitch gets captured without dropouts, and SecondBrain's summary flows straight into a proposal draft or follow-up email — one less thing to scribble while you talk.
Interviews & PR (marketers)
For marketers who do a lot of off-screen primary research — interviews, on-site reporting — the risk of a missed transcript drops. The 35-hour battery also holds up through a full day covering an event.
PM & meeting ops
In-person meeting notes get handed off to SecondBrain, task extraction included. Online meetings already have plenty of note-taking tools, so PMs with a heavier in-person load stand to gain the most.
Being able to carry it always also means it can always be recording.
Open questions, and what to watch next
An always-carryable recorder carries the consent problem with it. Rules on recording calls and in-person conversations aren't uniform across jurisdictions, including Japan, and recording a prospect or interview subject without their knowledge risks trust. Genspark points to encryption and SOC 2/ISO 27001 certification, but the device specs don't say how a user is expected to disclose that recording is happening. Organizations adopting it will likely need to build their own consent workflow on top.
Shipping is currently limited to the US, Japan, and South Korea, so early validation will likely come fastest from markets with strong in-person business culture — Japan among them. Readers whose work centers on pitches or interviews may find it worth trying while the launch price holds; if your work is fully online already, there's little reason to rush.
