Panlexicon vs. Visual Thesaurus – Who Will Win?

Panlexicon vs. Visual Thesaurus: No, it’s not an epic city-smashing battle of giant robots versus dinosaurs. It’s a contest between online thesauri. When you need that perfect word, where should you turn?

Well one thing is sure – you should toss out your paperback copy of Roget and delete the bookmark to your grandpa’s, because thesauri have come a long way baby, and finding new words has never been more exiting, thrilling, or exhilarating.

Visual Thesaurus is just like it sounds. Rather than showing up in a boring list, your search term is displayed graphically, surrounded by nodes with related thoughts attached in a tree-like, categorized structure.

Visual ThesaurusLooks just like a tree, plant, growth, slime mold.

Click a nearby word and it zooms to center-stage. Then click the next, and so on, to spatially browse through a series of words in an intuitive process that doesn’t interrupt your flow of thought. It’s more like play than work.

For convenience, it keeps a history of recent searches, and you can click and drag special words into a list to save for later. It supports multiple languages (American English, UK English, Dutch, German, Spanish, and Italian). Multiple definitions of the selected word are listed to the side or on mouse-hover, and it will pronounce the word if you click the speaker icon.

Too tantalizing for words.


Visual Thesaurus is free for a limited number of uses and with restricted features. You can trial the full version for 14 days, after which it costs about $3 a month, or $20 a year.

I kept Visual Thesaurus on retainer as my go-to onomasticon until I stumbled upon in all of its simple, elegant magic.

The power of Panlexicon lies in its ability to search on multiple terms, which will bring up a larger spectrum of metonyms than most thesauri (including Visual Thesaurus). So it’s perfect for finding that just-out-of-reach expression when all you can remember are remotely-related numinous approximations of what you’re going for. Simply type two or more related words or phrases, separated by a comma, and voilà. (And of course, you can always search a standalone word.)

Results are displayed as a word cloud in alphabetical order, sized by relevance. Each synonym is clickable, which will add it to your search terms, narrowing down or expanding the results even further. This lets you really hone in on that elusive target. Its ability to search on short phrases and idioms is pretty useful, too.

Cloud technology has come a long way.

Moreover, Panlexicon is free. Really. I’ve tried to pay them several times, and they’ve assured me it’s a labor of love and don’t need my hard-earned coin. Which is too bad, because it is worth every penny I could be paying for it. I just hope that means it will never go away.

Compared to most thesauri (including Visual Thesaurus), it displays a higher number of obscure lexemes, which for fantasy and sci-fi writers is a must-have. I wish it would display archaic terms that, no really, no one uses anymore, but we can’t have everything.

Sadly, it’s missing a few features I’d grown used to on Visual Thesaurus. I want it to display definitions, perhaps through a mouse-hover, though that couldn’t work on a touch screen device.

And the lack of antonym results is unfortunate.

In my fantasy world, Panlexicon would leverage the untapped potential of searching by antonym. Imagine the raw power you’d wield if you could include an antonym in the search itself, like so: “engaging, magical, !lackluster” Maybe someday.

Occasionally, Panlexicon completely fails to find connections between obvious associations, like last week when no combination of the words “nurturing, comforting, healing” brought up results. If this happens, be sure to try other tenses. “Nurture, comfort, heal” worked a little better.


Anguish, indeed.

For cases like these, it would be nice if Panlexicon could crowd-source suggested connections. Or at least if, behind the scenes, it factored in commonly co-searched terms to give it some element of self-learning.

Which, as we all know, is how the robot overlords will learn English so they can get into law school and pass the bar to sue extinct giant reptiles for causing global warming. Which is how giant robots will win versus the dinosaurs. (Write tip: Always deliver the promise.)

Meanwhile, you now have two new choices when it comes to reference tools. Give them both a try, and I’m sure one of them will win your heart.
