Best AI Shopping Assistants in 2026
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 shine when you don't know what you want. Ask either one to compare three espresso machines and they'll do a good job summarizing reviews and tradeoffs. Where they fall short is the moment you've already chosen — neither tool can tell you whether buying it now wrecks your savings goal or whether the price is likely to drop.
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 don't understand your finances, and they won't push back on a purchase you shouldn't be making in the first place.
Phia is a fashion-focused price intelligence tool — it's strong at "is this dress a good deal" but limited to clothing and lifestyle products and disconnected from your accounts. See our Spence vs Phia comparison for a deeper breakdown.
Spence is the pre-purchase spending companion. It does the price 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 can't: 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
If you want help finding products or comparing specs, ChatGPT and Perplexity are good defaults. If you want help paying less at checkout, Honey and Capital One Shopping are fine. If you want help deciding whether to buy — with both product intelligence and personal financial context — Spence is the assistant in this list that's actually built for that question.
None of these tools are mutually exclusive. Many people end up using 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?
Most assistants are built to help you find a product or pay less for it — not to weigh whether you should buy at all. Spence is positioned around that gap: it adds safe-to-spend, cost-per-use, and goal tradeoff context to standard 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 — so it's not designed to give personal-finance-aware buy-or-wait advice. For that you generally need a tool built for it.
- What makes Spence different from other AI shopping assistants?
Spence is positioned as a pre-purchase spending companion rather than 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 — combining product intelligence with personal financial context.
- Do AI shopping assistants replace budgeting apps?
Not really. Budgeting apps like Monarch and Copilot focus on tracking and categorizing what you've already spent. Decision companions focus on the moment before money leaves your account. The two are complementary — one tells you what happened, the other helps shape what happens next.
