What you get

  • Recognize product name/specs from the page you’re viewing
  • Pull comparable prices from other sites and show a side panel
  • Keep you in context — no manual search or copy/paste
  • Work even when retailers don’t expose APIs

How it works

The workflow, in plain English

Before: You’re on Amazon looking at a monitor. You open 4 new tabs, search Best Buy, B&H, Newegg. You compare prices manually. 10 minutes.

After: A small panel slides in from the side of the Amazon page: “Best Buy: $349, B&H: $339, Newegg: $355.” You didn’t search anything. Dassi read the product name, checked the other sites, and brought the comparison to you. You never left the page.

Why traditional tools can’t: Price comparison extensions are hard-coded for known retailer product catalogs. Dassi works on any site by reading the product name from the DOM.

Step-by-step

  1. Open the product page you’re considering.
  2. Ask dassi to identify the model name/sku and fetch competitor pricing.
  3. Review the side-by-side comparison; adjust constraints (shipping, seller type).
  4. Click through only when you’re ready to buy.

Example prompts to try

  • “Find the best current price for this exact model across major retailers.”
  • “Show price + shipping + return policy for the top 3 options.”
  • “Only include sellers with 30-day returns.”

Tips for better results

  • Be specific about what you want injected into the page (buttons, filters, a panel, a summary, etc.).
  • If the page has multiple sections, tell dassi exactly what to focus on (e.g., “the transactions table” or “the diff for file X”).
  • Prefer safe workflows first: draft, summarize, label, and prepare — then take actions (submit, purchase) only after review.

Frequently Asked Questions

Is this only for Amazon?

No. It can work on many product pages because it reads the page and searches for matches elsewhere — not a hard-coded catalog integration.

How does it avoid mismatched products?

You can constrain matching with model numbers, sizes, and specs. If the page doesn’t contain a clear model, provide one.

Can it include coupons or promo codes?

Sometimes. If discount information is visible on the page or on competitor listings, dassi can incorporate it into the comparison.
