The manual nobody re-reads.
The small service specified on page 40 — and never looked at again — is what stands between a working boiler and a flooded basement, a healthy engine and a ruined one. Grej doesn’t just store what you own. It reads it, and puts it to work: the buried interval becomes a reminder before the part fails, and a question gets an answer grounded in your actual home, boat and gear.
Not just receipts and manuals — warranties, service history, drawings, inspection reports, the photo you took last spring. Everything about a thing, in one place, ready the moment you ask.

Every plan has every feature. What changes is how much you can keep in Grej, and how much AI you get each month.

Using Grej in your browser? It’s the same account — for now you subscribe on your iPhone, and the plan applies in the browser too.
What an AI credit is
Reading a receipt, pulling the service intervals out of a manual, answering a question about something you own — each one draws a few credits. Your credits come back at the start of every month. Photos of your things don’t count towards your document allowance, and nothing you have already put into Grej is ever removed because a plan changed.
That’s this month’s AI credits
Used them all? They come back on the 1st — or a bigger plan brings more every month.

Some things belong in your hand: the photo of a serial plate, a question asked in front of an open boiler, a receipt at the till. Others need a screen and a coffee — what a job has cost, what’s due this autumn, the steps someone else is going to follow. Grej is both, over one memory. Neither is a cut-down copy of the other.
- On your iPhone: capture, ask, and the there-and-then
- In your browser: the money, the plan, the instructions, the whole record
- One memory behind both — what you catch standing up is there when you sit down
Nothing to install in the browser: sign in, drop a photo or a receipt, and see what Grej makes of it.
