Best AI Reselling Apps Compared: 6 Pricing Tools Tested in 2026

You're standing in a charity shop holding something that might be worth money. You need to know, fast, before someone else grabs it. That's the job of an AI reselling app: photograph it, identify it, tell you what it sells for.

There are now half a dozen apps claiming to do this. Some are genuinely useful. Some are overpriced. Some look good in screenshots but fall apart at a car boot sale when you're scanning 50 items in an hour. We tested them all.

Full disclosure: we built Profit Prophet, so we're biased. But we've tried to be honest about where each app does well and where it doesn't, including our own weaknesses.

Quick answer

Best overall for in-person sourcing: Profit Prophet (unlimited scans, sold data, AI chat, fee calculator, 8 countries).
Best for multi-platform sold data: Underpriced AI (6 platforms, but limited scans per month).
Best free option: Google Lens + eBay sold filter (free, but manual and slow).
Best for antiques: WorthPoint (deep historical database, expensive).

Each app in detail

2. Underpriced AI

Free (3 scans total) | Pro: $9.99/month (30 scans) | Pro Plus: $19.99 (75) | Business: $29.99 (200)

The most established AI pricing tool for resellers. Pulls sold data from six platforms: eBay, Poshmark, Mercari, Facebook Marketplace, Etsy, and Depop. That multi-platform data is its biggest strength. If you sell on Poshmark and want to know what an item fetches there specifically, Underpriced shows you real sold comps from that platform.

Also includes batch scanning (upload 10 photos at once), a Chrome and Firefox browser extension for scanning online listings before bidding, price monitoring alerts, inventory management, and direct eBay/Etsy listing publishing.

Strengths: Multi-platform sold data is genuinely useful for deciding where to list. The browser extension is great for online sourcing and auction bidding. Well-established with a larger user base and more reviews.

Weaknesses: The scan limits are the main drawback. 30 scans per month on Pro means you can check roughly one item per day. At a garage sale or car boot where you need to scan 40-60 items in an hour, you'll burn through your monthly allowance in one morning. Extra scans cost $1 each or $5 for 5. No AI chat to ask follow-up questions. US-focused, though UK and other markets are supported.

Best for: US resellers who sell across multiple platforms and need sold data from Poshmark, Mercari, and Etsy alongside eBay.

3. Google Lens

Completely free

Point your camera at anything and Google identifies it. Fast, accurate, and free. It recognises brands, model numbers, labels, and even vintage items surprisingly well. The results link to shopping listings so you can see current prices.

The limitation is fundamental: Google Lens only shows asking prices, never sold prices. An item might show as "listed for $80" when it actually sells for $30. For identification it's excellent. For pricing it's unreliable.

Strengths: Free, fast, works on everything, great at identification. Available on every phone.

Weaknesses: No sold data at all. No listing generation. No inventory tracking. You still need to manually search eBay completed listings after identification. It's an identification tool, not a pricing tool.

Best for: quick identification when you don't recognise something. Use alongside a sold-data tool, not instead of one.

4. WorthPoint

From $29.99/month

A massive database of historical auction and sale prices going back decades. If you deal in antiques, vintage pottery, art, or collectibles, WorthPoint has pricing history that no other tool matches. The Marks Database helps identify pottery and silverware maker's marks.

Strengths: Unmatched depth for antiques and collectibles. Decades of historical pricing data. Maker's mark identification. Useful for items where eBay sold data is too recent to capture the full picture.

Weaknesses: Expensive at $30/month. Desktop-focused workflow, not designed for quick in-the-field scanning. Doesn't cover modern items like electronics, toys, or clothing well. Not a photo scanning tool: you search by text, not by camera.

Best for: professional antique dealers, serious vintage collectors, and anyone who needs historical price trends going back years.

5. ResaleScan

Free (3 scans) | Paid plans from $9.99/month

Newer entrant focusing on the declutter market: people selling household items rather than professional resellers. Photo scanning with AI identification, marketplace comparison, and basic listing generation.

Strengths: Clean interface. Multi-photo support. Aimed at casual sellers who want simplicity.

Weaknesses: Less data depth than Underpriced or Profit Prophet. Limited sold data. iOS only. More suited for occasional decluttering than serious reselling.

Best for: casual sellers decluttering their home, not professional resellers.

6. eBay Visual Search

Free (built into eBay app)

eBay's own visual search: tap the camera icon in the search bar, photograph an item, and see matching listings. It's free and built into the app you're probably already using to sell.

Strengths: Free, integrated with eBay, good at matching common items. Shows both active and completed listings if you know where to filter.

Weaknesses: Only searches eBay. Matching quality is inconsistent, especially for vintage or unusual items. Doesn't give you a price estimate, just shows similar listings. No AI identification, no listing generation, no inventory management. It's a search tool, not a pricing tool.

Best for: a quick check when you're already in the eBay app. Not a replacement for a dedicated pricing tool.

The real cost comparison

Price per month doesn't tell the whole story. What matters is cost per scan for how you actually use the app:

ScenarioProfit ProphetUnderpriced AIGoogle Lens
5 scans/month (casual)£0 (free tier)£0 (free tier)£0
30 scans/month£10.99 (unlimited)$9.99 (exactly at limit)£0
100 scans/month£10.99 (still unlimited)$19.99 + $25 extra = $44.99£0
200 scans/month£10.99 (still unlimited)$29.99 (Business) at limit£0
500 scans/month£10.99 (still unlimited)$29.99 + $300 extra = $329.99£0 (no sold data)

Google Lens is free but gives you asking prices, not sold prices. That makes it unreliable for buying decisions. If you scan 50 items with Google Lens and buy based on the prices shown, you'll overpay on most of them because asking prices run 25-50% higher than what items actually sell for.

The real comparison is between Profit Prophet and Underpriced AI. If you scan fewer than 30 items a month, Underpriced's Pro plan works fine and gives you multi-platform sold data. If you scan more than 30, the maths shifts heavily toward Profit Prophet's unlimited model.

What we'd recommend

If you source in person (car boots, charity shops, garage sales): you need unlimited scans and speed. You'll check 40-60 items per trip. Profit Prophet Pro gives you that for one flat monthly fee.

If you source online and sell on multiple platforms: Underpriced AI's multi-platform sold data and browser extension are worth the scan limits if you're checking 20-30 items a month from your desk.

If you're just getting started: use Profit Prophet's free tier (3 scans/day, every day) alongside Google Lens for identification. That costs nothing and teaches you how to evaluate items before you invest in a paid tool.

If you deal in antiques: WorthPoint for deep historical pricing, combined with any of the above for modern items.

The combination play: many serious resellers use two tools. Profit Prophet or Underpriced for AI scanning and sold data, plus Google Lens for quick visual identification of items they don't recognise. That covers identification, pricing, and listing in one workflow.

Try Profit Prophet free: 3 scans every day, no credit card needed. See what your items are actually worth with real sold data, fee calculator, and AI chat.
