An overview of Jasper's powerful features

What exactly does Jasper do for you? Here's a brief overview of some of its most impressive features:

AI-powered writing support

Thanks to these templates, anyone can skip the blank page and get straight to writing. They save an enormous amount of time, whether you want to create an hourglass blog post structure or follow tried-and-tested sales copy formulas.

Putting Jasper's AI editorial assistant to the test

To properly evaluate Jasper, I decided to test its main features as part of my day-to-day work for two weeks. Here are some of my personal experiences and impressions:

Quick and intuitive to learn

Getting to grips with Jasper was quick and intuitive. After creating an account, the integration tutorial gave me a useful overview of the tool's main features and capabilities. Within minutes, I was ready to start creating.

Helpful editorial suggestions

One of Jasper's key value propositions is its context-based authoring assistance. I found that the artificial intelligence quickly perceived what I was trying to say and provided relevant suggestions. For example, when I typed “Jasper helped me write this blog post … “the application suggested several different options, such as “faster than ever”

This feature proved extremely useful in overcoming writer's block on my first drafts. Jasper's suggestions triggered related ideas I could build on, or gave me a starting point I could refine.

High-quality error correction

Since I don't always pay much attention to grammar and syntax when writing my first draft, I loved Jasper's error correction features. It accurately highlighted misused words, repetitive sentences, punctuation errors and much more.

Jasper then provided a brief explanation of the problem and a correction. This made it easy for me to improve the quality and clarity of my writing in real time.

Natural rewording

When I needed to rework an existing piece of content, I would paste it into Jasper and ask it to reformulate the paragraphs. The tool did an impressive job of rewriting my content in a new way while retaining the original meaning.

The reworded content certainly didn't look like it had been written by a human, but it provided a solid starting point that I could then refine and personalize to suit my style.

Seamless collaboration

I also tested Jasper's collaboration features by inviting a remote colleague to jointly edit a document. We took it in turns to add and refine content in real time, Google Docs-style.

Seeing each other's changes instantly proved incredibly convenient compared to traditional e-mail edits.
