For homeowners
The manual you threw away.
- The manual that went in the recycling during the move.
- The paint color nobody wrote down, so every touch-up is a guess.
- The model number on a sticker behind an appliance nobody wants to pull out.
- The contractor's invoice, buried three scrolls deep in an inbox from two years ago.
- The warranty that quietly expired because no one was tracking it.
- The plumber's number, saved in a phone that isn't yours anymore.
WHL Residence establishes a private record of the house you actually own: what’s installed, what’s under warranty, and who serviced what and when. Our team prepares the record and hands it to you. It grows as you add to it, and at sale you can hand it to the next owner.
Inside the record
Everything about the house, in one place.
Eight modules cover what an owner actually needs to track. Each one grows as you use it.
Home Overview
The address, the year built, the square footage, the bedrooms and bathrooms: the baseline facts about the property itself.

Astra
Ask your home a question.
Every new home manual includes Astra, built by Werner Harmonic Labs, for the first year. Any cost after that is agreed in writing before anyone is charged; nothing is billed for Astra today. Astra tells confirmed home information apart from what was read from a document and not confirmed. It does not confirm anything itself.
“What HVAC filter does this home use, and when was it last replaced?”
The downstairs system uses a 20 × 25 × 1 filter. The most recent replacement was recorded on May 12. The next replacement is recommended this month.

Astra answers from this home’s records and shows the source it used. It is not a licensed professional, and it is instructed to point you to one when a question calls for it. Its answers can still be wrong.
Access & privacy
You decide who is added.
Every registered address receives one secure home manual. During controlled launch, WHL adds the household members and trusted professionals the current homeowner names, and each of them sees the whole record.
WHL’s administrators can reach the record for operations and support, uploaded documents and questions are processed by OpenAI, and an owner can create a read-only key for another system. The privacy policy explains each.
Household members
The people who live in the home with you.
Trusted professionals
A contractor, agent, or vendor you approve. During controlled launch, WHL adds and removes access at your request.
Future owners
The next owner, when you decide the time is right.
When you sell
You can transfer the record when you sell.
A home manual doesn’t end at closing. When you sell, the home record can be transferred to the next owner instead of starting from zero. You start the transfer, the buyer accepts it, and nothing moves before then.
How transfer worksAfter handover
What happens once the record is yours.
WHL Residence establishes the manual as a service. From then on it is yours.

We establish the record
You send what exists: plans, manuals, warranties, service records, vendor contacts. We organize it into the manual and follow up on what is missing.
It becomes yours
The manual is yours from the day it is delivered. WHL adds the people you name, and each of them sees the whole record.
It keeps growing
Log a service visit, upload a new warranty, note a renovation. Most of the value comes later, from a record you added months ago.
You can transfer it when you sell
The buyer receives the systems, documents and service history you kept. Nothing moves until you start the transfer and the buyer accepts it.
Each uploaded document is read before it is saved. Its summary is saved on the document, labelled as read from the file, so you can check it. Web pages found for its equipment are saved for Astra, which names them as web sources when it uses them.
