Household inventory · in development
Already at home? Know before you buy it again.
Scan a barcode in the store. In 2 seconds LarderIT tells you whether it's already at home, how many, and where. The whole family shares one list, and it lives on your own PC.
Android first. iPhone later. Nothing to pay during early access, because nothing is for sale yet.
The fourth pack of batteries
Stop buying things you already have.
The spare olive oil is behind the flour. The tape is in a bin in the garage. Nobody remembers, so someone buys more. LarderIT keeps count for the whole house, place by place.
How it works
Scan once. Check anywhere.
- 01
Scan it once
Scan the barcode and LarderIT looks up the name. Pick the place, say how many packs, done. No barcode? Type the name and print a label for it.
- 02
Check in the store
Scan anything on the shelf. In 2 seconds you see “Already at home”, with how many and where, or “Not at home · go ahead”.
- 03
Count at home
Scan a product or a LarderIT label to take 1 off or add a pack. Tap any count to type the real number when you check a shelf.
In the store
Two answers. Both in plain words.
Every result leads with the answer, then the detail. Color is never the only signal: each one comes with words and an icon.
- Already at home How many, where they are, and who added them last. “Buy anyway” is one tap, and you can undo it.
- Not at home · go ahead When it ran out and whether it's on the list. “Buying it” puts it in To put away.
Labels
Labels for everything without a barcode.
Bins, jars, the bulk rice, the box of spare cables. Print QR or barcode labels from your phone, or from the PC your printer is plugged into, then scan one to count what's inside.
- Seven Avery layouts on US Letter, from 6 big labels a sheet to 80 tiny ones, and six roll sizes for label printers
- Any brand of Avery-compatible paper, printed in black
- A label workbench on the PC: pick things room by room, see the sheet in the printer to scale, and finish a sheet that's already part used
- Scan a label at home: Used 1, Added 1, or type the count. Undo is always there
- Quick use: for things you use up often, each scan takes 1 off by itself
- The code is made on your phone, so a label you just printed works with no signal. Reprint it and it scans the same
- A test sheet of empty outlines, and a nudge across and down, because every printer feeds paper a little differently

Do we have…?
Search the way you talk.
Type “double A” and LarderIT finds AA batteries. Ask for “something for a headache” and it finds the painkillers, because it matches meaning as well as words. When it doesn't know your family's word for something, teach it once and it knows from then on.
Fifty real household questions, asked of a test house: the right thing was in the top three for 46 of them, and 21 of those were found by meaning where the words alone found nothing. The four misses are what “teach a word” is for. Meaning search runs on your own PC; with no signal the phone still searches its own copy by name.
For the whole house
Made for families, not warehouses.
Few required fields, exact counts, and nothing you have to log every day.
-
One household, every phone
Everyone joins with an invite code and gets their own login. Every change records who made it and when, so two phones never overwrite each other.
-
Shopping lists that write themselves
One for the weekly shop, another for the Costco run. Things the house runs low on add themselves to the first list, once, and every line says how many are already at home.
-
Tick it, then put it away
A ticked line waits in the trolley until you finish, on the phone or on the family PC. “Done shopping” turns the trolley into things to put away: confirm the place and the count, and only then do the numbers change.
-
Receipts stock the house
Photograph the till receipt. The phone reads it, your PC names each line the way your house does, and you check the list before anything is put away.
-
Works with no signal
Your phone keeps a copy. In a store basement, word search still answers, and changes are sent when you're back online.
-
Packs and units
An 8-pack of batteries counts as 8. Adding 2 packs adds 16, and “Use one” takes 1 off.
-
Room › Spot
Places have two levels, like Garage › Bin 4 or Pantry › Shelf B. Make a new one by typing its name.
-
A helper on your PC
Ask it to find something, put milk on the Costco list or line up labels to print. It runs on your own PC, every change it makes has an Undo, and it never prints or changes a count.
-
Bring your own AI agent
Agents like Claude Code can use the same tools over MCP, from the PC itself. What they change shows up on the PC's pages as it happens, with an Undo. An agent like that sends what it reads to its own AI company.
Your data
Your list lives in your house.
LarderIT Server runs on your family PC. Phones reach it on home Wi-Fi, or through a private network when you're out. We never see what's in your pantry.
- A Windows installer sets it up. No terminal, no Docker
- Phones pair by scanning a QR code on the setup page
- A backup every night, on your machine
- Search runs on your PC too, with an open model
- So does the optional assistant, through Ollama. It needs a graphics card that can run an open model, and it won't use one in the cloud
One thing we'd rather say than leave out: barcodes are read on the phone by Google's scanner, and it tells Google how often it ran — never what it read, never anything about your household. The privacy page says it in full.
No PC that stays on? We're considering a hosted version. Tell us if you'd want it.

Where we are
Our own family tries it first.
LarderIT is in development, and a piece only counts as done once it has worked on real hardware: the scanner against real grocery barcodes on a phone, a label sheet off our own printer. When the list below is finished we use it at home for two weeks, fix what gets in the way, and then open early access.

Questions
Before you ask.
Can I use LarderIT today?
Not yet. We're building it now, and our own family tries it first. Early-access members hear first when there's something to try.
Is there an iPhone app?
Android comes first. An iPhone app is planned for later. If your household has iPhones, say so in the early-access form. It helps us decide when.
What does it cost?
We haven't set prices, and nothing is for sale. The early-access form asks how you'd rather pay, and those answers shape the decision.
Do I need a computer?
For now, yes: LarderIT Server runs on a Windows PC that stays on at home. The installer sets it up with no terminal. We're also considering a hosted option, where we run the server for you.
Where is my data kept?
On your own PC. Phones connect to it on your home Wi-Fi, or through a private network when you're out. Your list doesn't go through our servers.
Does LarderIT use AI?
Two open models, both on your PC. One helps search match meaning. The other, which is optional, runs the assistant and helps name receipt lines, through Ollama. Neither sends anything about your house to an AI company. If you connect an agent of your own over MCP, such as Claude Code, that agent sends what it reads to its maker.
What do I need to print labels?
A home printer and US Letter label sheets in one of seven Avery layouts, such as 5160 (30 small labels) or 5163 (10 large ones), or a label printer that takes rolls. Ours is a Phomemo M20Pro. Print from the phone, or from the PC the printer is plugged into. Any brand of paper works, and labels are black only. Print a test sheet of empty outlines first, and if your printer sits the sheet a millimetre off, nudge the whole page across or down until it lines up.
Where does product information come from?
When you scan a new barcode, LarderIT checks your own list first, then Open Food Facts and UPCitemdb. If nothing matches, you type the name once.
