Check models and fees before comparing prices

Text exercise: Supply product snapshots, model names, region, currency and thresholds. Separate prices, shipping, taxes and promotion conditions.

Execution environment and usage

AI / software

Text chat (ChatGPT, Claude or Gemini)

Where to operate

Text chat such as ChatGPT, Claude or Gemini, adapted to supplied inputs

Getting started

  1. For example, open claude.ai and start a new chat where the location, account and usage conditions permit.
  2. Paste the prompt below and its de-identified text inputs. Supply product snapshots, model names, region, currency and thresholds.
  3. Check the output against the original inputs; a draft does not connect or operate the original automation service.

Setup and plan requirements

Complete authorized text, synthetic records, field definitions or rules specified by the exercise. This chat route uses already-obtained text or excerpts. Later checks of pages, files or test results require separate human inspection; mark missing results unverified.

Prompt portability limits

Portable as an adapted draft/analysis exercise, not equivalent functionality or output to the original automation.

Usage limitations

Historical stack: n8n + source scraper/provider + price normalization + alerts/scheduling if configured. Not hands-on tested. Check current version, plan, regional and integration permissions; a prompt does not configure the workflow.

Environment sources

適用情境 / When to use

Supply product snapshots, model names, region, currency and thresholds. Separate prices, shipping, taxes and promotion conditions. This data exercise does not implement price monitoring, schedule checks, send alerts or buy items. The index’s fixed schedule, email and spreadsheet details are not all implemented in the original example.

步驟 / Steps

  1. Prepare authorized product snapshots, identifiers, currencies and shipping details.
  2. Normalize prices and variants before applying a user-defined alert threshold.
  3. Check promotion conditions, availability, shipping and comparability with prior prices.

提示詞 / Prompt

Analyze [approved product snapshots], normalizing by [model/currency/region] and separating shipping, tax and conditions. Draft candidate alerts for [threshold], keeping unknown totals and different variants separate. Use existing data only; do not scrape restricted pages, schedule checks, message or purchase.

留意事項 / Cautions

  • Do not bypass anti-scraping restrictions or purchase automatically.
  • Missing mandatory costs prevent a lowest-total-price claim.

來源限制 / Evidence limits

The tutorial includes promotion links; time savings and price accuracy are not independently verified.

流程說明 / Workflow note

These steps and prompts are original, untested exercises by this site, not the author’s verbatim workflow. Reported results do not guarantee exercise outcomes.
