**Short answer:** Both SAIMON and Yasan improve search in an online store, but each approaches it a little differently. SAIMON combines full-text search, recommendation widgets, filters and, in the Enterprise version, an AI shopping assistant in the results. Yasan builds an AI shop assistant directly around search: it handles a simple query as ordinary search and, for a more complex sentence, brings in AI that works with parameters, gives advice and can continue in chat.

SAIMON is particularly interesting for a store on Shoptet that wants personalised recommendations and control over the order of products, categories and articles alongside search. Yasan makes more sense where shoppers type compound requests into search or need help with choosing.

## What is Yasan

Yasan is an AI shop assistant for online stores. Its main feature is search that adapts to the type of query:

- “Brit Premium dry dog food” is handled as ordinary product search.
- “Dry food for a large-breed puppy under €20” is understood as a product with several conditions.
- “What helps with a dog’s teeth?” is treated as a need on which the shopper should get advice.

It is the second group that tends to be difficult for traditional search. The shopper knows the category but adds the animal’s age, price, pack size or a specific problem to a single sentence. Yasan tries to turn this information straight into results.

It also uses the same product knowledge in its AI chat. A shopper can ask a follow-up question about the difference between products or their suitability for a specific situation. If the feature is switched on and the store provides the necessary data, Yasan can also show order status after verifying the customer.

## What is SAIMON

SAIMON is a Czech solution for product search and recommendations. It offers full-text search, typo tolerance, synonyms, a custom ranking strategy and the option to boost products, categories and articles. Alongside search it has recommendation widgets for the product detail page, categories, the basket or the homepage.

In the Enterprise version, SAIMON offers a shopping assistant. For a search term it can create an AI summary, recommend products and work with the content of products, categories and articles. As an example, the vendor gives the query “My dog smells”, which is meant to lead to dog shampoos.

So SAIMON is not just a search box. It is a set of tools for search, recommendations and commercial control of results, aimed primarily at Czech online stores and Shoptet.

## The main difference: commercial control of results vs. deeper work with the query

Both solutions can find a specific product and both use AI. They differ, however, in where they place the main emphasis.

SAIMON lets a store influence which products, categories or articles should be shown higher up, and complements search with recommendation surfaces. The AI shopping assistant extends the results with a summary and relevant content.

Yasan focuses more on understanding the shopper’s whole sentence. It is not just about the two extremes of “I know the exact name” and “I need advice”. The queries in between matter too: “dry food for a large puppy without chicken”, “red harness size M under €30” or “dental treats for a small dog”.

## Comparison by situation

| Situation | Yasan | SAIMON |
| --- | --- | --- |
| Exact product or brand | Ordinary search results | Full-text search, autocomplete and relevance control |
| Typo or synonym | Works with the meaning of the query | Typo tolerance, synonyms and phrase fixes |
| Product with price and other parameters | Tries to turn the conditions straight into results | Parameters can be handled through search and filters; it depends on the implementation |
| Open-ended need | AI answer, products and the option to ask follow-up questions | The Enterprise shopping assistant can create a summary and recommendations |
| Follow-up question | Can continue in AI chat with the same knowledge of the catalogue | The shopping assistant works in the search results; check the options for a follow-up conversation with the vendor |
| Recommendations elsewhere on the site | Not the main focus of the product | Widgets on the product detail page, in the category, on the homepage and in the basket |
| Commercial control of order | Less emphasis | Boosting and a custom ranking strategy |

## How we compared

The comparison is based on both vendors’ public websites, verified on 1 November 2026, and on a short, informal trial on several live stores in October 2026. It was neither a benchmark nor a representative sample, so we do not use results from individual stores to rate the products.

On the stores we tried, SAIMON coped well with exact queries and correcting diacritics. The shopping assistant was not switched on in all of them, which is consistent with it being a feature of the higher version.

For your own decision we recommend a simple procedure: take 20–30 real queries from your customers, including the ones that end with no results today, and try them in both solutions on the same catalogue. The quality of answers and results depends mainly on product data and configuration, which differ for every store.

## Where SAIMON has the edge

### Recommendation widgets across the store

SAIMON can work with similar products, cross-sell and personalised recommendations at several points in the shopping journey. That matters for a store that wants to improve not just search but also product discovery in categories, on the product detail page and in the basket.

### Control over order and content

A store can boost products, categories and articles and set its own ranking strategy. This is useful where results should reflect sales performance, preferred brands, new arrivals or commercial priorities.

### Strong focus on Shoptet and the Czech market

SAIMON offers Czech-language support, a Shoptet add-on and custom configuration of the appearance. For a store that wants to deploy and fine-tune the solution with a local team, this approach can be an advantage.

## Where Yasan has the edge

### Several conditions in one sentence

Yasan tries to understand not only the product but also the price, size, use or other constraints written directly in the query. The shopper does not have to set each condition again in the filters.

### One interface for search and advice

It handles an exact query as ordinary search. For a more complex query AI is brought in, and the shopper can continue with a question in chat. The product knowledge stays the same.

### Chat and order information

Alongside search, Yasan also offers AI chat built on the catalogue. Depending on the integration, it can also help the customer with order status after verification. That is not the main purpose of SAIMON.

### Public pricing

With Yasan, the standard plans and limits can be seen in advance. With SAIMON, the price is prepared according to the size of the store and the features chosen.

## Pricing

Yasan lists the plans Starter at €31.99, Go at €82.99 and Pro at €206.90 per month excluding VAT. All of them include AI search and the AI chatbot; a 14-day trial is available.

SAIMON does not publish a specific amount. Activating the add-on is followed by contact with support, a custom quote and a test version free for 14 days. According to the [SAIMON add-on page](https://doplnky.shoptet.cz/saimon), the price depends on the size of the store and the features chosen.

## When to choose SAIMON

SAIMON is probably the better choice if:

- you need to complement search with recommendation widgets on the product detail page, in the category and in the basket;
- you want to boost products, categories or articles according to commercial priorities;
- shoppers mostly search for names, brands and common phrases;
- custom pricing based on the scope of the solution suits you.

An example: a pet supplies store wants to control the order of pet foods, recommend treats in the basket and display relevant articles on category pages. Its shoppers mostly search for a brand or a type of food.

## When to choose Yasan

Yasan is probably the better choice if:

- shoppers add several parameters and constraints to their searches;
- you need to understand sentences that fall between an exact name and a general request for advice;
- you want the shopper to be able to continue from search into AI chat;
- you want to use the same knowledge of the catalogue for both search and product advice;
- you prefer public pricing and use Shoptet, Shopify or WooCommerce.

An example: shoppers often search for “dry food for a large-breed puppy without chicken under €50” or “a harness for a dachshund that doesn’t press on the neck”. The main problem is not the order of products but understanding the whole need.

## When you need neither

Neither SAIMON nor Yasan may make sense if you have a small catalogue, clear categories and shoppers easily find products using a few clear filters. It also pays to fix product names, parameters and descriptions first. Neither AI nor advanced full-text search can work reliably with information that is missing from the catalogue.

## Verdict

SAIMON is stronger where a store is looking for a broader combination of full-text search, recommendations and commercial control of results. Its shopping assistant adds an AI layer, but its availability and depth depend on the solution chosen and the specific implementation.

Yasan is the better fit where shoppers search in natural sentences and combine a product with a price, a property or an intended use. It also connects search with AI chat and, depending on the integration, with order information.

The deciding question is therefore: do you primarily need to manage and recommend your range across the store, or do you need search to understand better what the shopper has typed? The first situation favours SAIMON, the second Yasan.
