Best AI Shopping Assistants
Most AI shopping assistants help you find products. Few help you decide whether to buy.
What is an AI shopping assistant?
"AI shopping assistant" has become a catch-all label for any tool that uses generative AI or machine learning to help you research, compare, or buy products. In practice the category splits into three rough buckets:
Discovery assistants — like ChatGPT, Perplexity, and Google's AI overviews — help you surface options and summarize specs or reviews. They're great when you don't know what you want yet. Deal and price assistants — like CamelCamelCamel, Honey, Phia, and Capital One Shopping — track prices, find coupons, and surface alternatives. They help you pay less for something you've already chosen. Pre-purchase decision companions — the newest and smallest bucket — answer the harder question: should you buy this? Spence is built for that step.

Where each assistant actually fits
ChatGPT and Perplexity can help when you do not know what you want. Ask either one to compare three espresso machines and they will summarize reviews and tradeoffs. They cannot tell you whether buying it now wrecks your savings goal, whether the price is likely to drop, or whether the purchase fits your safe-to-spend. Discovery is not decision.
Honey, Capital One Shopping, and CamelCamelCamel are deal tools. They live at checkout or on Amazon product pages and try to save you a few dollars. They do not understand your finances, and they do not push back on a purchase you should not be making in the first place. A lower price is not the same as a smart purchase.
Phia compares fashion prices. It is limited to clothing and lifestyle products and disconnected from your accounts. A cheaper item is not automatically a smart purchase. See our Spence vs Phia comparison for the deeper breakdown.
Spence is the pre-purchase spending companion. It does the product intelligence work most assistants do, then layers in financial context (safe-to-spend, cost-per-use, goal tradeoffs) so you can answer the question that most other tools cannot: should I buy this right now?
When to use Spence
Use Spence when you're about to spend. The right moment is the one between "I'm thinking about it" and "I've already paid." That's the window where most AI shopping assistants don't show up at all.
Specifically, Spence is the right fit when:
• You've already found the product but you're not sure if now is the time to buy.
• You want to know if a purchase will set back a savings goal you actually care about.
• You want a one-text answer that combines price, reviews, resale value, and affordability — without juggling five tabs.
• You don't want another app, account, or subscription on top of what you already have.

The verdict
Most AI shopping assistants help you find a product or pay a little less for it. Spence helps you decide whether to buy at all. If you want discovery, ChatGPT or Perplexity can help. If you want a coupon, Honey or Capital One Shopping can help. For the actual buy-or-wait moment, with product intelligence and personal financial context in the same answer, Spence is the assistant in this list that is built for that question.
The tools are not mutually exclusive. Many people use a discovery tool to research, a deal tool to find a coupon, and Spence as the gut check before they tap "buy."
Frequently asked questions
- What is an AI shopping assistant?
An AI shopping assistant is software that uses AI to help you research, compare, or buy products. The category includes discovery tools (ChatGPT, Perplexity), price and deal tools (Honey, CamelCamelCamel, Phia), and pre-purchase decision companions like Spence that add personal financial context to the decision.
- What's the best AI shopping assistant for deciding whether to buy something?
Spence. Most assistants help you find a product or pay less for it. They do not weigh whether you should buy at all. Spence adds safe-to-spend, cost-per-use, and goal tradeoff context to product intelligence so the question shifts from "where do I buy this?" to "should I buy this?"
- Are AI shopping assistants free?
It varies. ChatGPT and Perplexity have free tiers and paid upgrades. CamelCamelCamel, Honey, and Phia are free. Cleo has a free tier with paid features. Spence is free with no subscription. Always confirm pricing on the tool's own site before relying on a paid feature.
- Can ChatGPT help me decide whether to buy something?
ChatGPT can summarize reviews, compare specs, and surface options. Out of the box it does not connect to your bank accounts, calculate your safe-to-spend amount, or weigh a purchase against your savings goals. It is not designed to give personal-finance-aware buy-or-wait advice. For that, Spence is built for it.
- What makes Spence different from other AI shopping assistants?
Spence is a pre-purchase spending companion, not a discovery or deal tool. It runs in iMessage with no app to install. You text it a product link or screenshot and it responds with price comparison, cost-per-use, resale value estimate, review summary, safe-to-spend amount, and goal tradeoff framing. It combines product intelligence with personal financial context, which is the gap most AI shopping assistants leave open.
- Do AI shopping assistants replace budgeting apps?
Not really. Budgeting apps like Monarch and Copilot focus on tracking and categorizing what you have already spent. Decision companions focus on the moment before money leaves your account. The two are complementary. One explains what happened, the other helps shape what happens next. Spence is built for the second.
