Butler, as a brand sees him — over sample figures, not a real account.
The shift
You already have the data. You do not have it in time.
Amazon gives every seller the same reports. What changes the week is how quickly somebody reads them, and whether the reading survives being busy.
Before
A spreadsheet export, once a month
With Butler
A live account pulse, every day
Before
You found out about the price change a week later
With Butler
Graded overnight and waiting for you in the morning
Before
Rank checked by hand, when somebody remembered
With Butler
Tracked daily, with the week's movers written out in words
Before
Six tabs, six logins, six versions of the truth

How it works
Watch. See. Act.
There is no onboarding project, no data team, and nothing to plug in. If NAYF Group manages your advertising, Butler is already watching.
- Step OneLive today
Watch
Your account data flows in every day. Nothing to install, connect or maintain — Butler has done the reading by the time you open him.
- Step TwoLive today
See
How the account performs, what moved and by how much, what changed on your listings, where you rank, what a category is worth — every figure scoped to your brand and to nobody else's.
- Step ThreeComing
Act
Today Butler reads; he does not write. When actions arrive, each kind will be off until you turn it on, and every one will need a named human's approval — recorded, every time.
The modules
Six live now. More on the way.
Each one is scoped to your brand, refreshed daily, and written to be read rather than interpreted.
- Live
Performance
Spend, sales, efficiency and return, with the daily shape underneath — each measure set against the preceding period of equal length, so a number always has something to mean.
- Live
Movers & Shakers
What actually moved, ranked by how much money it moved. Not by the largest percentage on the smallest number, which is how the real story gets buried.
- Live
Listing Health
A graded change log: price moves, buy-box switches, availability and content edits, sorted by how much they matter rather than when they happened.
- Live
Rank & Visibility
Every tracked keyword by day, with the week's movements written out in plain English — 'three places better', not a number you have to decode.
- Live
Niche Research
A category, measured and written up: who is already selling there, what the middle of the market earns, which search terms are still open — and our read on whether it is worth entering.
- Live
Price & Market
Your price today against the rivals we watch, what has moved since last week, and where two of your own offers are competing with each other. Built once, for every brand, rather than as a one-off report — and switched on per account.
Not built yet — on the roadmap

Profit & P&L
Fees, cost of goods and VAT resolved into true net profit per product — and the advertising running into the products that lose money on every unit sold.

Butler in Teams
Ask Butler a question in the channel you already use, and get an answer scoped to your brand. He will always be visibly a bot; he will never claim to be a person.
Security
Careful by construction.
Butler holds a view of a business somebody has spent years building. The restraint below is designed in, not promised.
Butler reads. He does not write.
Today Butler has no path to change anything on your Amazon account — not a bid, not a price, not a word of copy. When that changes, each kind of action is off until you switch it on, and every one is approval-gated and recorded.
Your brand is walled off.
Every request is checked against your membership on the server, never in the browser. That isolation is re-proven automatically on every single deploy, against real signed-in users — and a failure blocks the release.
Reporting runs on read-only credentials.
The credentials behind your figures can read the warehouse and do nothing else. There is no write path to revoke because there is no write path.
Invitation only. No passwords.
Access is by invitation, and you sign in with a single-use link sent to your email. There is no password to guess, reuse, or leak.
Your figures sit in our own warehouse.
Not in a product we rent on your behalf and not in a shared tenant. The database behind Butler is hosted in London.
Access
Not for sale.
Seller Butler is not a subscription and has no checkout. He is included with NAYF Ads management — which is why he can be built properly rather than to a price.
Not with NAYF Ads yet? Apply anyway. Tell us about the business and we will talk about both.
Every application is read by a person here — usually within a couple of working days.
Questions
The things people ask first.
What is Seller Butler AI?
NAYF Group's private application that watches your Amazon business and reports on it: how the advertising is performing, what moved this week, what changed on your listings, and where you rank. It reads your account every day and writes the findings in plain English.
Who gets access?
Brands that NAYF Group manages, and our own team. Access is by invitation, one brand at a time — which is why there is an application form rather than a sign-up button.
What does it cost?
Nothing. Butler is included with NAYF Ads management and is not sold separately. There is no plan, no seat count and no checkout.
Can Butler change my Amazon account?
Not today. Butler reads your account and reports; he has no write access to it at all. When actions do arrive, each kind will be off by default, will need a named human to approve it, and will be recorded.
Where does my data live?
In NAYF Group's own warehouse, read through credentials that can only read, and in a database hosted in London. Your brand's figures are walled off from every other brand, and that wall is tested on every deploy.
How do I apply?
Use the form on this page. Already a NAYF Ads client? Say so and we will open your brand. Not yet? Tell us about the business and we will talk about both.
