AI Synonyms

Automatically generate context-aware synonyms that align with your catalog structure, improving semantic matching in search and filtering systems.

Automatic synonym generation

Shoppers don’t always search with the exact words used in your catalog. They say “running shoes” when you say “sneakers”, “cell phone” instead of “smartphone”, or “laptop bag” when your product is labeled “notebook sleeve”. Traditional systems often miss these variations — leading to irrelevant results or even zero matches.

AI Synonyms closes this gap. It automatically generates intelligent, context-aware synonym suggestions using advanced GPT-based language models, allowing your search engine to speak your customers’ language — whatever that may be.

How it works

  1. Detect low-performing queries:
    • AI Synonyms automatically scans your search analytics and identifies search terms that produce poor or zero results.
  2. Generate GPT-powered synonyms:
    • With one click, it uses large language models (LLMs) — specifically GPT — to generate a list of relevant synonyms and alternative phrases based on the context of your product data.
  3. Review with confidence:
    • Each suggestion includes a relevance score, so merchandisers can quickly decide which synonyms to accept, edit, or reject — no guesswork involved.

Why AI Synonyms matters

- Increases search accuracy

Context-aware synonym suggestions make product discovery easier and more relevant — even when users phrase things differently.

- Saves merchandisers time

Forget manually reviewing search logs and crafting synonym rules. AI Synonyms reduces workload by up to 70%, freeing your team to focus on strategy.

- Learns language like a human

Because it’s powered by GPT, the model understands spelling variations, brand names, regional differences (e.g., “trainers” vs. “sneakers”), and even slang.

- Multilingual support

Supports synonym generation in multiple languages, making your search engine more inclusive and globally effective

Smart synonym suggestions, no manual work

Most e-commerce synonym tools rely on exact matches or manually maintained synonym lists.
AI Synonyms goes further — using the same GPT technology behind ChatGPT to analyze and expand your vocabulary based on how real people search.

- Learns from your actual product data
- Generates long-tail, phrase-based synonyms (not just one-word pairs)
- Continuously improves over time
- Fully controllable and reviewable by your team
