Fine jewelry with aperfect memory.
deHertz is worn, not carried. Let it listen through your whole day or just one conversation, then hand you back every word — transcribed, summarised and searchable in seconds.


Hear it work
Press, and say anything.
The part nobody can picture from a screenshot is what it feels like to speak and watch the words arrive. So try it — right now, in your browser.

Honest note: this is your browser's engine, not ours
No audio is uploaded and no request reaches us — check your network tab. Our own transcription is more accurate, keeps speakers apart and follows a sentence that changes language halfway. What this shows truthfully is the shape of the thing.

The film
Fifteen seconds, start to finish.
The pendant, the day it hands back, and the three languages in one conversation. Everything in it is the real product and the real app — nothing rendered, nothing staged.
One day with deHertz
You talk. It remembers.
Not a feature list — a Thursday. Three conversations, and what you get back from each.



Real screens from the current build.
- 9:05 AM
The site walk you didn't take notes in.
Forty-two minutes on floors five and six. You were looking at the glazing, not at your phone. The pendant heard it, and by the time you're back in the car the decisions and the two things you promised are already written down.
- 11:30 AM
The client who switches languages mid-sentence.
Fatima opens in Arabic, you answer in English, the budget is in numbers. The transcript keeps every speaker and every language in its own script — and the reminder she asked for is set for Thursday, 2 PM, before you've hung up.
- 6:40 PM
The whole day, on one card.
Three conversations become one recap: what was decided, what's still open, who promised what. Read it in the time it takes the valet to bring the car.
What it does
Crafted like jewelry. Built like AI.
Not a list of features. What you actually get back at the end of a day, shown as it arrives.
Handover holds at Monday. Glazing on floors 5–6 moved to Tuesday; a second supplier is approved up to AED 15,000 if it slips.
- Confirm the glazing date, in writing, by tomorrow evening
- Send the revised fit-out line item before Sunday
You get the summary, not the transcript
Every day ends with one page: what was decided, what's still open, and who promised what. The full transcript sits underneath for when someone disagrees.

Two point four, including fit-out.

15 languages, in the same sentence
Meetings here switch mid-thought. It follows the switch instead of asking you to pick.
12 Mar · Supplier call · 14:22
“…the lead time on the glass is six weeks, not four…”
28 Feb · Site meeting · 09:41
“…if the lead time moves again we switch supplier…”
Search everything you've ever heard
Not a folder of recordings. The exact sentence, with the date and the room it was said in.

Reminder · Thursday 3:00 PM
Send the contract to Ahmed — you said Thursday.
Promises become reminders
Say a date out loud and it becomes a notification. The thing you said you'd do on Thursday arrives on Thursday.
Encrypted, never trained on
In transit and at rest. Your audio never trains a public model, and nobody here browses it.
18 hours on a charge
A full working day, then some. 7+ days on standby, 45 minutes from empty to full.
Worn, not carried
A 36mm medallion on a fine chain. It reads as jewelry, which is why it can sit in rooms a phone on the table can't.
The app
Where the conversation becomes useful.
The pendant listens. The app is where a day of talking turns into something you can read in a minute and search in a second. These are the real screens, from the current build.




iOS 15 and later. Android 9 and later. Included with the pendant — no separate subscription.
Finishes
Two, and no wrong answer.
Same pendant, same 36mm body, same everything inside. The only question is whether you want it seen.


Drag to turn it in the light
Why not just your phone?
The honest comparison.
Where a phone or a meeting bot is the better choice, we say so. For the conversations that happen in person, this is the difference.
| deHertz | Phone recorder | Meeting bot | |
|---|---|---|---|
| Works in person | Yes, worn all day | Yes, if you remember to start it | No — video calls only |
| Changes the room | No, it is jewelry | Yes — a phone on the table is noticed | Yes — a bot joins visibly |
| Summaries | Automatic, per conversation and per day | None | Usually yes |
| Search across everything | Full-text, every recording | No | Within that tool only |
| Arabic support | Yes, 15 languages including Arabic and Urdu | Depends on the app | Often weak outside English |
| Cost | AED 499/year, hardware included | Free | Typically a monthly seat fee |

One price. Everything included.
