People often confuse a 'price comparison site' with an 'AI agent'. The first shows a list when you ask it to. The second understands your intent, goes and fetches the information, puts it in context, and can act over time (watch, alert). This guide explains what an AI shopping agent is and how to get the most out of one.
Comparison site vs AI agent: what's the difference?
| Classic comparison site | AI shopping agent | |
|---|---|---|
| Interaction | Forms / filters | Plain language |
| Judgment | Shows the prices | Explains if it's a real deal |
| Memory | None | Remembers your preferences |
| Proactivity | You have to come back | Alerts you when the price drops |
What an AI shopping agent can do for your groceries
- Understand a fuzzy request ('a cheap breakfast idea').
- Compare stores and compute the all-in price.
- Optimize a whole list (split cart or single-store).
- Pull applicable coupon codes and cashback.
- Watch a product and email you at the right moment.
- Remember your brands and constraints to personalize.
The trust engine: the DealScore
For an agent to be useful, it has to be honest. Pépite scores every offer out of 100 based on price vs history, the real discount, cashback, shipping, and merchant reliability — and shows the reasoning. A fake markdown on an inflated price gets penalized, not promoted.
Proactivity: the real time-saver
The biggest value of an agent is that it works even when you're not using it. Put your recurring purchases on price watch: the agent re-checks prices continuously and tells you when a product hits your target or a coupon appears. You stop buying at the mercy of the calendar and start buying at the right moment.
How to get started
Open Pépite, describe a product or paste your list, and let the agent do the work. It's free to start; the Pro plan adds unlimited price watches and real-time alerts.
