Competitor prices, diffed every morning

Each morning the Browser Agent visits every product page on your watch list, reads prices, promotions and stock, and logs them in a history sheet. You get a short diff by email — who moved, by how much, who undercuts you — and silence on the days when nothing changed at all.

The problem

Everyone watches competitor prices; almost nobody does it well. The honest version is a person clicking through rival sites on Friday afternoon, pasting numbers into a sheet until something urgent interrupts — so the one week a competitor moved is the week nobody looked. The industrial version is a monitoring subscription that emails a spreadsheet of four hundred rows a day, which gets skimmed for a fortnight and then filtered away.

Neither gives you the thing you actually want: a tap on the shoulder saying “these three prices moved, this one now undercuts you” — and silence the rest of the time.

How your Aivell does it

  1. The round runs before opening. At 06:30 the Browser Agent visits every page on the watch list — a real browser, reading each page the way a shopper would, promotions and stock included.
  2. History is kept, not shown. Every reading is appended to the history sheet, one row per item per day. It’s there when you want a chart; it never lands in your inbox.
  3. The diff is the product. Yesterday against today, computed onboard. Unchanged items are dropped; movements are listed with direction and size; anything undercutting you by more than 5% goes on top, in bold.
  4. Disappearances are tracked, not ignored. A vanished product or a dead page is noted and rechecked — often the earliest signal a rival is clearing stock.
  5. Luca reads it with his first coffee. The diff arrives before 08:00. On quiet days, nothing arrives — and that silence is information too.

The guardrails keep the colleague honest: only listed domains, no logins unless you grant them, never a basket, never a purchase — and a history that can’t be quietly rewritten. Competitive eyes, wide open, entirely inside your walls.

The chore, as you'd write it.

No flowcharts, no code — a chore is just a message to your Aivell, in your own words. It shapes it into a solid, guarded procedure and follows it to the letter. This one:

Giulia Aivell · watch competitor prices ● active

every morning at 06:30, visit the product pages on the watch list

read current price, promo flags and stock status for each item

log every reading in the history sheet, one row per item per day

compare with yesterday — unchanged items don't make the report

a competitor undercuts us by more than 5%? top of the report, in bold

a page or product vanishes — note it, check again tomorrow

email Luca the diff before 08:00; stay silent when nothing moved

once a month, add a short trend note per competitor

The tools it uses.

Connected with single-click passkeys — no copied tokens, no OAuth hell.

Browser Agent opens the pages, reads the prices
Spreadsheets keeps the full price history
Email sends the diff — only on change

Sensible guardrails.

Every tool can be limited to exactly what this chore needs. For this one, you might set:

Browser Agent Visits only the domains on the watch list. Logging in, adding to basket or buying is blocked.
Spreadsheets Appends to the history sheet; past readings can never be edited.
Email Sends only to Luca and the pricing list — the diff never leaves the company.

Questions, answered.

Won't competitor sites just block a bot? +

The Browser Agent is a real browser reading a handful of pages once a day — the traffic of one person window-shopping, not a scraping farm hammering a site. It behaves like the polite visitor it is.

Can it watch wholesale prices behind a supplier login? +

Yes. Give it the account, whitelist that domain, and it checks the trade prices too — while the guardrail still makes ordering or changing anything on the account impossible.

Why does it matter that this runs in my office? +

Because a watch list is a strategy document. Hand it to a cloud monitoring service and a vendor knows exactly which rivals you fear and which products you defend. On the box, that knowledge stays where it belongs — with you.

I don't want a spreadsheet of numbers every day. +

You won't get one. The sheet keeps the history quietly; the email is a diff — three lines on a normal day, nothing at all when nothing moved. The 5% undercut rule decides what deserves bold type, and that rule is yours to rewrite.

What is an Aivell?

An Aivell is an on-premise AI colleague: a small box that plugs into your network, runs its own AI onboard and takes the repetitive work off your desk. Prompts, documents, data — nothing ever leaves your office. Unplug the internet: it keeps working.

You describe each task as a chore, in plain language. Your Aivell turns it into a solid, guarded procedure and runs it in the background — with guardrails on every tool, a complete audit trail, and approvals in your hand when you want them. One-time setup, fixed monthly fee. No tokens, no overages.
