Why Should You Use Content Writing Apps?

Content writing apps are your ticket to fast and effective content creation. They bring about capabilities that were unthinkable back in the day, so even if you prefer to do most of the work manually, you can still save some time in the process. 

In 2025, you might encounter lots of different app types, from a content writing app for Instagram to tools focusing on nuances, like Grammarly. Some of these options can be used to correct grammar and spelling errors, while others focus on niche aspects such as SEO, research, and editing.

Plus, we’re beginning to see all sorts of AI-powered options that cater to a wide range of users. For instance, you can use tools like Claude.AI for deep research and help with crafting briefs and outlines for human writers to follow. 

Overall, the best free content writing tools we’ve outlined in this guide can help you top to bottom, from structure and formatting to writing errors and content optimization.

How to Pick the Best Content Writing App for Your Needs

We must admit that even our experts needed some time to narrow down the options from hundreds to the 5 best content writing apps in 2025. The thing is that more and more solutions fitting the profile emerge on a daily basis, many of which feature similar, generative AI solutions and quirks. 

Still, one thing is for sure: choosing the best content writing app largely depends on the purpose. Are you looking for grammar and writing style assistance across multiple platforms? Or, do you require an AI-powered app to do some quick digging on the topic to cut the time spent on research? We’ve even found some apps that act as both writing tools and publishing platforms, so you can get all the work done in one place.

The bottom line is that there is no ultimate writing app suitable for all purposes. You need to find what works best for you, and in some cases, these tools are best combined if you’re looking for peak quality in writing.

Best Content Writing Apps in 2025

While crafting this list, we were focused on finding the best content writing tools for beginners, but we also wanted to bring you some expert-level options. Explore our 5 final picks and find out what's special about each.

1. Grammarly

For those looking to use content writing apps free, Grammarly ticks all the right boxes. To be exact, you can only use its basic version without being charged anything, but it’s more than enough if you only require some grammar assistance and simple writing suggestions.

This tool follows your every writing step by immediately scanning for grammar and style errors. When it runs into problematic segments, it marks them with a color, and you can just click to get real-time writing recommendations. Still, for a price of $30 per month, you can opt for Grammarly Premium and get expert insights and suggestions for each sentence.

The top-shelf version also delivers an integrated plagiarism checker, so you can immediately scan the text for originality. 

Other than that, the tool uses AI to pick up on your writing patterns, which allows it to give you personalized suggestions and writing tips. 

Pros:

• Great writing tools for beginners
• Grammar and style error insights 
• AI writing style suggestions 
• Plagiarism checks 
• Advanced insights into your writing with performance tracking details

Cons:

• The Premium version is rather expensive 
• All the colored insights and suggestions might be a bit distracting

2. Google Docs

Google Docs is one of the best content writing apps for the writing process itself, which explains its widespread use. It’s available across all major platforms, from Windows PCs and laptops to Android and iOS mobile devices.

Still, where Google Docs truly stands out is in collaborative writing. It’s an ideal solution for writing agencies and teams working on the same documents. Writers and editors alike benefit from its numerous features, such as document version history, which allows you to track progress with time tags. 

We liked its different modes (writing/editing, suggesting, and viewing) and customizable access permissions, in particular. It also allows you to leave comments throughout the article, and its integration with Google’s Workspace makes it a reliable option for those who need a collaborative content writing and sharing tool.

Pros:

• Real-time collaboration capabilities
• Free of charge
• Cross-platform accessibility
• Cloud storage with automatic saving 

Cons:

• Lagging issues with larger documents 
• No writing assistance features (other than the integrated spelling checker)

3. Surfer SEO

When it comes to search engine optimization, Surfer has positioned itself as the best content writing app. It provides basic writing assistance, coupled with detailed SEO insights and analytics. You can also use it for keyword research and generating article outlines, among other things. 

The tool includes an SEO score tracker, which shows you how your piece rates against other articles with the same target keyword. Unfortunately, it doesn’t come for free: you’ll have to pay $79 per month for the Essential plan or up to $175 per month for the Scale package.
‍
There’s also a custom Enterprise option with on-demand pricing for major companies in need of writing assistance. We’d recommend it as the perfect choice for content marketers and affiliate bloggers who want to see their pieces rank higher on SERPs. 

Pros:

• Robust SEO features and score tracking
• Article outline generation based on keyword research
• AI-powered content suggestions and tips
• Keyword integration recommendations

Cons:

• Steep learning curve
• Costly membership plans

4. FocusWriter

FocusWriter is one of the best content writing apps for anyone who struggles to stay on task. It strips your writing area of any AI features or attention-grabbing add-ons, leaving you with a minimalist workspace that resembles a virtual blank page.

On top of that, it features an option to block all notifications on a given device, allowing you to focus on writing entirely. It was because of this feature that our team ranked it highly among the best content writing apps for Android and other mobile platforms. 

It’s also fully customizable, as you can pick your theme, ambient sounds, and other on-page elements for a creative boost: we enjoyed setting up the scriptwriter sound when typing, in particular. Other features, like progress tracking and tailored writing backgrounds, contribute to your productivity without compromising your focus.

Pros:

• Best tool for maintaining focus when writing 
• External factors (such as notifications and visual distractions) blocked
• Fast typing performance
• Customizable theme and typing sound

Cons:

• A small number of collaborative features 
• No grammar or spelling checks 

5. Medium

Last but not least, we’d recommend Medium as one of the best content writing apps in 2025 when it comes to writing and publishing. It already boasts a large community of readers and writers, who can give you a "clap" if they like your content. It also helps you reach communities with reading preferences that match your writing style.

Through its partner program, it’s also possible to earn money from content distribution and the audiences your blogs attract. It also features a clean interface that allows you to combine it with other apps and tools that you might be using for passive income. 

Whether you’re a YouTube creator or simply want to give your email list a bit of an organic boost, Medium is the option to go for. We’d also point out its 1-on-1 programs and consultations to help novice writers reach expert status.

Pros:

• Rewarding in the long run through content sales 
• Helpful for finding a suitable audience for your type of content
• Simple for beginners to use 

Cons:

• Lacks customization features 
• The reach of your content is determined by the algorithm 

Summary

Overall, finding the best content writing apps in 2025 wasn’t as simple as it seems, let alone crowning the best one. Still, to sum things up and pick a winner, we’d recommend Google Docs as a free option worth its weight in gold.

It’s perfect for collaborative efforts and editing, while it can be combined with other options, like Grammarly for fine-tuning your content for any grammar and spelling errors or Surfer for SEO tasks. If you’d like to focus on the task alone, FocusWriter is the best pick in that regard. As the cherry on top, we picked Medium for its dual purpose of both being a writing and a publishing platform.
