What Are Ludwig And Grammarly?

Ludwig and Grammarly are two writing assistants that perform different functions. Ludwig is like a search engine that gives contextualized examples of words, allowing you to write better English.

Let’s say English isn’t your first language. You’re writing an article or assignment for work, and don’t know what a particular word means or how to use it in a sentence. Simply type it into the Ludwig search engine, and it provides sentences in the best contexts.

On the other hand, Grammarly is a writing assistant specializing in spotting grammar, spelling, and readability problems. Copy and paste your article, novel, or school assignment into the software, and you’ll find all Grammarly’s suggestions on the right. From here, you can accept or reject changes based on their accuracy.

Grammarly also has a plagiarism checker which helps you spot duplicate content. This is handy for students because it’ll prevent hefty plagiarism penalties

What do Ludwig and Grammarly Have In Common?

Although Ludwig and Grammarly are completely different tools, they share some similarities, the biggest one being the paraphraser.

Grammarly and Ludwig allow you to paraphrase your content if it sounds awkward or wordy. If Grammarly identifies a sentence to paraphrase, it underlines the sentence in blue. You can paraphrase it by clicking the suggestions on the right of your screen.

Ludwig Vs. Grammarly: The Differences

I’ve been using Ludwig for a few weeks to check phrases and words for context, and this is the biggest difference I noticed:

  • Ludwig helps you understand the English language
  • Grammarly focuses on improving your writing

Ludwig Helps You Understand The English Language

Ludwig targets non-native English writers even though it can benefit your life if your first language is English. It helps you learn about the context of words and phrases to create more engaging content.

Or, if you’re a French speaker, for example, and want to translate something into English, you can use Ludwig’s translator.

Paste the word or sentence into the Ludwig interface, select the French language, and you’re good to go. This is a more accurate method of translation compared to Google Translate.

Grammarly Improves Your Writing

While Ludwig helps you understand context, Grammarly focuses on fixing your writing. It’ll check your work for:

  • Grammar
  • Spelling
  • Readability
  • Plagiarism

This makes Grammarly a good option for different types of writers, students, and team leaders. After using Ludwig for a couple of weeks, this is where I feel it falls short. It’s designed to help you understand the context of sentences, but it won’t check your articles for errors.

What’s Better About Ludwig?

However, there are areas where Ludwig does a better job than Grammarly:

  • Ludwig gives context to sentences
  • You can translate writing with Ludwig

Ludwig Gives Context To Sentences

What stood out about Ludwig is that it gives context and meaning to words and phrases. For example, if I’m trying to incorporate the phrase “social media” into my writing, I can type it into Ludwig, and it’ll provide me with a definition and examples of how to use it.

As you can see, these examples come from reputable websites such as The Independent and The New York Times. 

You Can Translate Writing With Ludwig

The main problem with Grammarly is that it only works in English. This is impractical if you’re creating content in multiple languages. Fortunately, Ludwig allows you to translate your writing into several languages including:

  • French
  • Italian
  • Spanish 
  • German
  • Dutch

So let’s say you’re a native French speaker. You’re writing in English and trying to think of a word to use, but you only know how to spell it in French. All you have to do is type it into Ludwig. The app will convert your French into English and provide definitions and examples.

What’s Better About Grammarly?

These are two areas in which Grammarly thrives but Ludwig falls short:

  • Grammarly checks for plagiarism
  • Grammarly in a more complete writing assistant

Grammarly Checks For Plagiarism

One of my favorite Grammarly features is the plagiarism checker. If it wasn’t for this feature, I would need to sign up for and rely on other tools to scan my work for duplicate content.

Fortunately, I can paste my articles into Grammarly and when I’m finished checking for grammar and spelling, I can focus on removing accidental plagiarism.

Grammarly Is A More Complete Writing Assistant

Grammarly is a more powerful writing assistant because it checks for almost every possible mistake and uses AI. It isn’t perfect and will miss sometimes suggest errant fixes, but it’s an excellent foundation to start content editing.

This is what separates Grammarly and Ludwig. While Ludwig will help you understand English better and translate your work, Grammarly offers more features and supports more use cases.
