Google Cloud Vision API Product Search vs Lenso.ai

Google Cloud Vision API Product Search lets retailers build catalogs from products and reference images, organize them into product sets, and find visually or semantically similar items from query images. Supported categories include homegoods, apparel, toys, packaged goods, and general. Query images can come from Google Cloud Storage, a web URL, or a base64 string. Optional product-label filters support AND or OR expressions under documented rules. Calls are available through REST, RPC, and Google Cloud client libraries, while CSV import can create product sets, products, and reference images in bulk. The free plan covers prediction and storage for 0–1,000 images monthly. Listed paid storage starts at $0.10 per 1,000 images; prediction is $4.50 or $1.80 per 1,000 at higher tiers. Index updates occur approximately daily. Limits include 20 MB images, 10 MB JSON objects, and 16 images per request.

Lenso.ai is an AI reverse image search service that finds people, places, duplicates, related images, and similar images from an uploaded picture. Users can refine searches with text keywords or a website domain, save results to collections, and receive email alerts for new matches. Results include source URLs, but the free account allows daily searches without letting users unlock results or view their sources. Starter includes 50 source-link unlocks and 10 alerts; Professional adds Research Mode, advanced filters, and DMCA Assist Mode. Research Mode can show up to 10,000 results for People and Duplicates. The Developer plan lists Face Search and Reverse Image Search APIs, with up to 5,000 API calls. Face search is available only in selected regions; Face Search API users must live in an eligible region and sign an agreement. Lenso.ai says uploaded images are not saved or shared and are not used for AI training. Paid plans are listed from $19.99/mo. The maker also says shared search links remain active for up to six hours after the last interaction.
