Plan my groceries for the week
I checked what you usually buy and what's running low. Here's the list for your next trip — 12 items, mostly produce and dairy. Want me to find this week's deals on these?

Your groceries, handled in a sentence

No app to open, no list to retype. Ask, and it is done.

It already knows what you buy

Your assistant reads your purchase history, so "plan the week" produces your actual staples — not a generic list you have to fix.

It finds the deals you would have missed

Every Belgian chain leaflet, cross-referenced against your list, in the time it takes to ask. No flipping through folders.

It tells you where to go

One question scores every chain on price and how much of your list they actually cover, so you stop guessing.

What you can ask

Three things people do every week. Your AI handles each in one turn.

“Plan my groceries for the week”

Pulls your purchase history, surfaces what's running low, drafts a 12-item list — you confirm, it adds them to your need list.

uses: get_purchase_history, get_smart_reminders, add_to_need_list
“What's on sale worth getting at Colruyt and Delhaize this week?”

Searches active promos at both chains, cross-references your base list, returns the deals that actually match what you buy.

uses: search_promos, get_chain_promos
“Where should I shop this week?”

Scores every chain against your need list using current promos. Tells you the cheapest store, the most complete one, and the trade-off.

uses: calculate_optimal_store

A skill that teaches your AI to use l1st.ai well

A small playbook your AI installs once. It learns the difference between your base list and need list, speaks your language, knows your default stores, and runs these five workflows from a single phrase.

Plan my week

"Plan my week"

Looks at your usual buys and what's running low, drafts a list, waits for your confirmation, writes it to your need list.

What's on sale worth getting

"What's on sale worth getting?"

Searches active promos at your default chains, returns only deals on products you actually buy.

Where should I shop this week

"Where should I shop?"

Compares stores against your need list, surfaces the cheapest and the most complete with the trade-off.

In-store mode

"I'm at the store"

Reads your need list back to you and marks items off as you go.

After-shop reconciliation

"I'm back from shopping"

Asks what you bought, removes it from the need list, adds anything new to your base list.

Before you connect

Does this cost extra?
No. The MCP server is included with your l1st.ai account. Core features are free forever; the AI features it can reach follow your normal plan.
Do I still need the app?
Only if you want it. Everything stays in sync — add items from chat, check them off in the app in the store, or the other way around.
What can the AI actually see?
Only what your prompt asks for, and only through the tools listed above. It reads your lists, purchase history, and public promo data. It cannot see your payment details or change your subscription.
Can I disconnect it?
Yes, instantly. Revoke access from your l1st.ai settings and the connection is dead — no need to touch your AI provider.

You stay in control

  • You grant access
    OAuth login. l1st.ai never sees your AI provider account.
  • Revoke any time
    One click in your settings cuts the connection.
  • Your data stays in l1st.ai
    The AI only reads what your prompt asks for.
