Cortana will start suggesting better deals as you shop on Amazon, Walmart, eBay, other retailer sites using Edge browser
Microsoft's digital assistant Cortana will now be able to save you money when you're shopping online. The company announced today that it will begin a pilot test …
Context & Ripple Effects
This 2017 pilot reads very differently against the decade of related coverage around it. Cortana had already been pushed toward proactive assistance — turning commitments in emails into reminders — and this deal-suggestion test extends that same assistant logic from calendar management into commerce, planted directly on rivals' retail pages inside Edge.
The pilot turned out to be the first step in a long Microsoft sequence: Edge later shipped built-in coupon and promo codes, Bing gained AI-generated buying guides in 2023, and by 2026 Copilot in Edge could draw on open tabs and browsing history to answer shopping questions. The through-line is Microsoft repeatedly re-entering the shopping journey from the browser side rather than owning a store.
First-order effects
- Shoppers browsing Amazon, Walmart, and eBay in Edge get unsolicited cheaper-alternative prompts from Cortana, meaning Microsoft inserts itself between those retailers and their own product pages during the purchase decision.
Second-order effects
- Retailers whose listings get undercut by Cortana's suggestions face pressure to keep prices competitive inside a browser they don't control — while Amazon's parallel willingness to integrate with Microsoft elsewhere (the Alexa-Cortana cross-invocation rollout) shows the rivalry staying cooperative at the platform level even as Edge mediates its storefronts.
Third-order effects
- If the pattern holds — coupons in 2020, GPT buying guides in 2023, Copilot reading tabs and history by 2026 — the browser matures from a passive window into a shopping agent, shifting pricing power and purchase influence toward whoever owns the assistant layer rather than the merchant whose site hosts the transaction.
The trend: Browsers are evolving into agent-mediated shopping surfaces, with Microsoft iterating the idea from Cortana deal prompts through Bing buying guides to Copilot-powered answers over nearly a decade.
