What is the Best AI Writing Software?

Best Overall:

jarvis

I chose Jarvis.ai as the best overall AI writing assistant simply because it's the market leader in features and quality by a long shot.

They have over 50 AI content generation templates to choose from and are constantly coming up with new use cases.

Jarvis templates include:

  • Blog posts (it can write entire blog posts from scratch with minimal inputs). This includes generating blog outlines, intro and conclusion paragraphs, body text and blog post ideas
  • Emails. This includes an email subject line generator, body text generator and personalized cold email generator
  • Marketing copy. This includes the AIDA framework (Attention-Interest-Desire-Action), the PAS framework (Problem-Agitate-Solution) and the BAB framework (Before-After-Bridge), as well as a marketing headline and sub-headline generator

What is AI-Based Writing?

AI-based writing refers to the use of artificial intelligence as a means for composing content such as blog posts, ads, landing pages, marketing copy, product descriptions and other written work.

While there are many different types of AI writing programs, they all make predictions and suggestions based on what has been written before and then use machine learning techniques to create content like a writer would.

Can Artificial Intelligence Really Write Original Content?

Yes, artificial intelligence can produce 100% original content that's indistinguishable from that created by humans.

The reason is that these programs are trained to read immense amounts of content written by humans and then become writing experts through high-speed repetitive learning, typically done through the use of a neural network.

How Do AI Writers work?

Artificial intelligence represents the marriage of natural language processing and machine learning algorithms.

AI software engineers first "teach" a neural network what makes for compelling reading, either by examining samples of human prose or through sheer experimentation on its own.

After acquiring this instinctive knowledge over time and intense repetition, AI writers can mimic real-life writing with uncanny accuracy while generating text that's typo free and has perfect grammar.

What to Do Next

The best way to appreciate the capabilities of AI writing assistants to generate original text for your content project is to take them out for a spin.

Most of the above tools offer either free trials or a money back guarantee. To get a good sense of what they do, I recommend that you first try Jarvis.ai (the editor's choice) since it provides the most content creation options.
