The best AI shopping assistant for choosing a laptop may be different from the one you want when a pair of shoes is already in your cart. Start by deciding whether you need product research, a catalog search or discount information.
Passt is our product, so it is included with that relationship made explicit. This guide compares the approaches and their published capabilities. It does not rank them by measured savings or claim a head-to-head performance test.
Match the assistant to the shopping task
| Approach | When to consider it | What to check |
|---|---|---|
| ChatGPT shopping research | You want help narrowing a product choice | The supporting sources and current retailer details |
| Claude with a shopping connector | You want catalog results in a Claude conversation | Which connector ran and what it covers |
| Perplexity shopping | You want research alongside supported shopping features | Whether the product and your account qualify for the purchase flow |
| Manus coupon finder | You want to investigate coupon offers for a named item or store | The offer source, eligibility and accepted checkout price |
| Passt in ChatGPT or Claude | You want indexed product results and any supplied published discount information | Catalog coverage, freshness and the store's final price |
These are overlapping options. Passt runs inside an assistant; it is not a replacement chat model.
ChatGPT for researching a product choice
OpenAI describes shopping research as a way to explore and compare products through a conversation. That makes it worth considering when you are still deciding what to buy.
Give it the requirements that would change your decision, then inspect the retailer pages behind the shortlist. Separate recommendations about suitability from facts such as the current price of a particular variant.
Claude with a catalog connector
Claude supports connected services that can retrieve information in a conversation. A shopping connector gives you a named source to request alongside the rest of your brief.
This is useful if you already work in Claude and want to refine a shortlist there. Check whether the answer came from the connector or another source. Installing a connector and having it used for a particular answer are separate events.
Perplexity for research and supported purchases
Perplexity documents product research and an Instant Buy flow for eligible products and accounts in the United States. Availability depends on the merchant and account; a search result is not automatically eligible for that checkout.
If purchasing in the same service matters to you, verify that the exact product supports the flow. Read the merchant's delivery, return and order information as part of the decision.
Manus for a coupon search
Manus offers a coupon-finder workflow starting from a product, store or link. Its page describes finding and checking offers.
Evaluate the particular result you receive. Look for a source and applicable terms, and confirm the price in your own cart. A provider's description of verification does not establish that a specific offer will apply to your order.
Passt for catalog information in your existing chat
Passt connects ChatGPT or Claude to the GenesisPay catalog. It returns products from the stores the index reads, with listed prices and any published discount information supplied in the results.
Choose it when you want that catalog available in your conversation. It is free and needs no separate Passt account. It cannot search every store, promise the lowest market price, apply a code or purchase anything. You buy at the store's website. Some marked links earn GenesisPay an affiliate commission.
Compare tools with the same shopping brief
Before relying on any assistant, try one real task with requirements you can verify. Use the same product variant, country, budget and search time for each option.
Record whether each answer provides a matching product, a source link, a listed price, relevant conditions and a clear account of missing details. For discount results, separately record whether the code was merely supplied or actually accepted for your cart.
Compare the final delivered price rather than the biggest claimed percentage. An assistant that accurately returns no usable offer can be more helpful than one that supplies several unsourced codes.
If you already use ChatGPT or Claude and want to try a catalog search, add Passt. Keep the first task specific, inspect the results and decide whether the coverage fits what you buy.
