Fast Simon is an AI search, filters and merchandising platform for online stores, sold on tiered monthly plans metered by shopper sessions. What decides whether it suits you is how many sessions your store generates a month, since every tier is built around a session ceiling that raises the price as traffic grows.
What is Fast Simon?
Fast Simon is based in Los Altos, California, in the United States. It works with Shopify, WooCommerce, BigCommerce, Adobe Commerce and Wix, and has its own listing on the Shopify App Store, founded in 2014.
How Fast Simon search works
Fast Simon directs shoppers by intent rather than exact keyword match, and corrects typos automatically as part of its instant search and autocomplete. Synonym, "did you mean" and antonym handling are included from the Starter plan up, alongside custom product filters.
Search results can be personalized per shopper, and shoppers can search by uploading an image. Manual curation of results is available on every plan, with merchandising rules and A/B testing added on the Top Pro plan. Search analytics covers AI insights, conversion tracking, filter usage and real-time dashboards.
Integrations and setup
Fast Simon runs as a web-based admin dashboard with a JavaScript widget embedded in the storefront, backed by a documented SDK for developers. It integrates with Klaviyo, Langify, Okendo, Stamped.io, TapCart, Yotpo and Dotdigital.
Fast Simon pricing: what each plan gives
The Free plan costs nothing and includes 100 monthly sessions, search filters, AI instant search and autocomplete, typo correction, a no-code editor, manual curation and daily catalogue sync. All paid plans include a 14-day free trial.
Starter costs $39.99 a month ($33.33 a month billed yearly) and adds 2,000 monthly sessions, Did You Mean, Synonyms, Antonyms, custom product filters, Business Impact Analytics and hourly or on-demand catalogue sync. Essential costs $99.99 a month ($83.33 a month billed yearly) for 10,000 monthly sessions, and Top Pro costs $299.99 a month ($249.99 a month billed yearly) for 30,000 monthly sessions. The price rises with monthly sessions across every tier, and billing has no minimum term.
Who Fast Simon suits
Fast Simon suits stores on Shopify, WooCommerce, BigCommerce, Adobe Commerce or Wix that want AI-driven search, filters and manual merchandising without committing to a contract, and that can start on the free plan while traffic is still low.
It suits less well a store with heavy traffic on a small budget, since the price rises with monthly sessions, from 2,000 on Starter to 30,000 on Top Pro.

APPROSEARCH
Fast Simon has a free plan and prices scale with your session volume, starting at $39.99 a month; APPROSEARCH has no free plan, only a 14 day trial, and prices scale with your catalogue size instead. Fast Simon personalizes results for each shopper, a feature APPROSEARCH lacks, though APPROSEARCH adds webhooks and GDPR compliance. Both support image search.

Pick Fast Simon if you want a free plan and results personalized per shopper.
Wizzy
Fast Simon's cheapest paid plan is $39.99 a month with a free plan to start on; Wizzy has no free plan and starts at $199 a month instead.
