How it works

The workflow, in plain English

Before: A TV is listed at $599. Good deal? You have no idea. You search CamelCamelCamel in another tab. Maybe.

Step-by-step

  1. Open a product page.
  2. Ask dassi to fetch and display price history context.
  3. Review current price vs. average and recent lows.
  4. Decide: buy now or set a target price.

Example prompts to try

  • “Show price history for this product and label if it’s above average.”
  • “Tell me the best time to buy based on past discounts.”
  • “Compare current price to Black Friday levels.”

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

Where does price history come from?

It may come from publicly available tracking data or comparisons across time. Coverage depends on the product and retailer.

Can it set alerts?

dassi can help you track targets, but alerting depends on your preferred workflow (email, calendar reminder, etc.).

Does it account for shipping and bundles?

If those details are visible, it can incorporate them. Always verify the final checkout price.
