It's the best suggestions engine! Scroll down to read about how we created it.

Try it ☝️. Please let us know what you think of it so far! 🙏 👨🏼‍💻 👩🏽‍💼 About us

We have put a lot of effort into creating the finest thesaurus and text-analysis algorithms.

The examples above prioritize nTLDs. We specialize in finding relevant nTLDs. Example: for search term "food", we'd suggest .recipes, .menu, .cafe. You may configure your API settings to prioritize gTLDs or ccTLDs like .net,.biz, .io, .ly, or any TLDs which you wish to promote.

Our engine uses new proprietary technology:
  • the most complete and powerful custom database of English words and phrases.
  • sentiment-analysis, to never offend anyone.
So, we're able to:
  • pick out the most relevant TLDs out of thousands, reliably every time!
  • be playful and creative with our suggestions, without fear of creating a cringeworthy phrase.
  • draw from a vast pool of words and phrases, and come up with natural sounding suggestions.

Our suggestions are improving every day! We're adding logic and content for more clever and reliable results. The app is currently slow (development mode). Certain queries may not give perfect results yet (we're still testing all possible cases). Still adding pop-culture terms, slang, names, brands, before/after, etc. Please let us know what worked for you and what didn't. Let us know what features are important to you.

  • How we do it:

  • Our Proprietary Thesaurus Database (

    We meticulously compiled and edited the best English language thesaurus of 330,000+ words, including some short phrases and foreign words. A corpus of 10,000,000+ words, Wordio contains 2.5x more entries than Oxford or Our synonyms are conversational, positive, and short.

  • Sentiment Analysis AI

    Language can be riddled with negative connotations that hold ethnocentric, biased, or insensitive meaning.

    Take “black” for example. A thesaurus will often give negative suggestions such as “dirty” or “evil”. Other problematic words were “woman”, “girl”, and proper nouns like “Nike” or “Asian”. We took care of many of these issues, manually and programmatically, then thoroughly tested.

    We now have the most accurate sentiment analysis algorithm that leaves only positive, clean, culturally appropriate synonyms. We are passionate about an inclusive internet for everyone .

  • All The TLDs

    Most visitors are not aware of all the new TLDs like “.casa” for home-related or “.law” for legal topics. Your visitors are missing out on great domain names. You are missing out on domain sales and recurring customers.

    newTLDs + genericTLDs = we find all the relevant and meaningful extensions related to the visitor’s search term, sorted by relevance.

    ccTLDs = we know that “.ai” means Artificial Intelligence, “.io” is used by tech startups, etc. We’ll treat these the same as nTLDs and gTLDs - detect their meaning, and include when relevant and meaningful according to your rating. But also, we'll use any TLD to create a word hack - we'll suggest "" if "" is not available.

  • You control which TLDs to use, and which to promote!

    You can give each TLD a rating, based on how highly you want to promote it. Highly rated TLDs will float to the top of suggestion results.Low rated TLDs will float to the bottom and won't be used as often. But regardless of the rating, we will ONLY use the TLDs which are relevant to the user's search term.

  • Word Hacks / Domain hacks

    Our algorithm finds creative word and domain hacks - like turning "" into "", "", "", "", "", "", or "".

  • Markov Strings

    We have developed some clever algorithms, to arrange words in unique but meaningful ways.

    Markov strings are combinations like "adjective -> noun". Simple ones like this are just scratching the surface of NLP (Natural Language Processing), but we already use them to create fun and catchy 2-3 word phrases. We are actively expanding our linguistic capabilities.

  • Spell check

    If your visitor types in a misspelled phrase like "". Even if the user meant to misspell the name, like for a brand name, it's still useful to figure out the underlying meaning, to match the most relevant TLDs.

  • Reliable parsing + word breaking

    User may search "". We parse it into individual words, and extract meaning from each: "multi", "word", "domain", "name".

  • Brand, name, and entity extraction

    We can determine if a word or phrase mentions a person's name, a brand, or any other proper noun. Still working on improving the accuracy, but already very useful. Our suggestions algorithm can then say "hello {Name}" or "get {Brand}", and perform other logic and optimizations, and suggest more relevant TLDs.

  • Before/After

    We already utilize the open-source DataMuse API to suggest words that naturally come before the user's search term.

    We are currently expanding this functionality. We're working on collecting data from public articles around the internet, and evaluating the most likely before/after words and phrases, for even better suggestions! Combined with our linguistic software, this will be an impressive feature!

  • Enterprise Ready

    For smaller clients, or just to test our service, our APIs are available instantly with no contract, on

    Once you're ready, you may sign a contract with with us, and access our servers directly, at a discounted rate. To further increase performance, we will spawn new web servers as close as possible to your data centers (or customers, if you send API requests from the client). We'll work with you to make anything possible.

    You can even host our API on your own server to avoid sending any web requests. Get your results instantly. This option would require an unlimited license, and some custom development. Ask us about this or any other feature you'd like to see.

Let's talk business. Let's talk tech.

This product is still improving every day. We're currently working hard on new features, even better results, and powerful sorting and filtering options. Tell us what's important to you. We can make it happen!

The API is now available at RapidAPI. We're currently optimizing our code and servers for production and scale. We're rolling out a globally distributed cloud infrastructure - for fast responses anywhere in the world. Soon, you'll be able to query our servers, without going through RapidAPI, or even host on your own server.

We are now beginning to collaborate with interested registrars. We see this becoming the new standard in domain search results. Increase your market share. Gain more recurring customers. Increase your domain sales.

We have 12 years of experience in web development. We can help you query our data on your site.

Beat your competition

You can be one of the first in the industry to use this tool. We can even develop some custom features for you.

These suggestions are already much better than anything out there, using these results, you will improve your UI, earn more recurring customers, and increase market share.

We imagine that the bigger registrars may insist on an exclusive contract. Hurry up and get yours before it's too late!

Our data and algorithms are improving every day! We're still adding features, editing, and testing. Please let us know what worked for you, and what didn't. Please let us know what features you'd like to see!

Easy to integrate...

Our API uses modern standards (JSON/REST). It is very easy to use. See our API documentation. Tutorials and example code coming very soon.

If you need help with integration, we have 12 years experience in web development and UI design. Let's do it together!
