The Best AI Writing Tools in 2025 Compared

You’ve heard all the buzz about AI writing tools. 

But how do you choose the right one for your content projects?

Based on my own tests, here are the best AI writing tools compared through their features, strengths, and potential drawbacks

1. ChatGPT, Claude, and Gemini Default Interfaces

ChatGPT, Claude, and Gemini provide the most versatile interface, where you can input complex prompts and generate content instantly from the latest foundational LLM model. There’s usually nothing better in terms of control and personalization. 

Pros

• Wide Accessibility: Both ChatGPT (via OpenAI) and Claude (via Anthropic) offer free versions or low-cost plans, making them affordable and accessible to a wide audience.
• State-of-the-Art: you usually get immediate access to the latest models. 
• Versatility: these interfaces can provide more advanced features like search, graphs, and image generation in ChatGPT.  
• Flexible Output: You can easily adjust the style and tone of the content by modifying your prompt, giving you control over the final output.

Cons

• Lack of Structure for Long-Form Content: While these models perform well for short pieces, they struggle with creating highly structured long-form content, like reports or technical documentation. You may need to spend time manually organizing and editing the output.
• Repetitive Output: Sometimes, the responses can feel formulaic or repetitive, particularly if you’re asking for multiple pieces of similar content. This can lead to bland or uninspired results.
• Limited Creativity: Although these platforms are powerful, they often lack the creativity and innovation that more specialized tools (like Grok 2 or Jasper) can provide. For more nuanced or imaginative content, you might need to enhance their output.

Pricing

• ChatGPT: OpenAI’s ChatGPT offers a free version, while the ChatGPT Plus plan costs $20 per month. This gives you access to GPT-4, which provides more advanced features like faster response times and higher-quality output.
• Claude: Anthropic’s Claude 1.3 also has a free plan and offers more advanced paid options depending on the usage.
• Gemini: Google DeepMind’s Gemini typically integrates with Google’s enterprise services. While there are free access points through Google’s broader AI tools, advanced features and large-scale usage may require customized enterprise pricing.

2. Copy.ai

With a user-friendly chat interface and pre-built workflows, Copy.ai is perfect for writers without extensive prompting or training.

• Brand Voice Customization: Based on a sample of your writing, Copy.ai can adapt its output to mimic your brand’s voice, ensuring that all generated content stays consistent with your style and tone.

Cons

If you need specific content formats or more detailed control over output, you may need to make manual adjustments.
• Dependency on Provided Data: The accuracy of Copy.ai’s content can depend heavily on the quality of the document or data you upload. Without precise input, the AI might generate content that needs significant refinement to meet your standards.

Pricing

What are the Best AI Models for Writing?

Foundational LLM models are the ones powering AI writing tools. What if you want to leverage directly from their default interface?

Here are the AI models that generate the best style, consistence, and prose :  

1. Claude Sonnet 3.5

Claude Sonnet 3.5 is known for producing some of the most engaging and well-structured prose among AI models.

Pros

• Engaging Writing: The output is more natural and less robotic compared to many other models, making it perfect for creative projects.
• Good at Mimicking Style: Whether you need a friendly tone for a blog post or a formal one for a business report, Claude Sonnet can adapt well.
• Consistency in Reasoning: It can produce well-reasoned and logically structured text over long pieces of writing, reducing the need for heavy editing.

Cons

• XML Writing Format: One of the major drawbacks of Claude Sonnet 3.5 is its limited output formats. It often generates content in XML format, which can complicate the process of extracting usable content.
• No Web Search: Unlike some other models, it does not have real-time web search capabilities. This limits its ability to pull in the latest data or fact-check information during content generation.
• Easily Censored: The model tends to be heavily censored when it comes to generating content that involves sensitive topics. This can limit its versatility, particularly for businesses that need more nuanced or critical discussions in their content.

Pricing

Claude Sonnet 3.5 is available primarily through Anthropic’s custom API, with prices starting at around $0.02 per thousand tokens.It’s also available from Claude Chat interface starting at 20$ month. 

2. GPT-4

GPT-4 is widely recognized as one of the most powerful language models available today. Developed by OpenAI, it’s designed to handle a wide range of tasks, from casual conversation to detailed content creation.

• Easy-to-Read Content: You’ll find GPT-4 excels at creating content that’s not only informative but also accessible to a wide audience. Its friendly tone makes it a great option for customer-facing content.
• Adaptability: Whether you need a formal tone for business writing or a casual style for blogs, GPT-4 can adapt to your needs, which saves you time on editing.
• Web Search Integration: When paired with tools that allow real-time search, GPT-4 can pull in the latest information, making it more reliable for up-to-date content.
• Structured Format: If you need clear, concise, and well-organized content, GPT-4 performs well at delivering coherent output across various content types.

Cons

• Repetitive Outputs: If you’re working on long-form content, GPT-4 may sometimes fall into repetitive patterns, which can make the text feel monotonous.
• Bland Tone in Longer Texts: While it produces helpful content, GPT-4 can sometimes generate bland, unengaging text, especially in long-form articles. This means you might need to refine the tone to make it more compelling.

Pricing

GPT-4 is available through OpenAI’s API, with pricing based on usage. Rates typically start at $0.03 per 1,000 tokens for basic tasks, making it affordable for most content creation needs. You can also access GPT-4 through platforms like ChatGPT Plus, which costs $20 per month, giving you access to its advanced features and faster response times.

3. Llama 3.1 700B

Llama 3.1 700B, developed by Meta, is a powerful open-source language model that focuses on performance and flexibility. Unlike proprietary models like GPT-4 or Claude, Llama 3.1 can be run locally without needing to rely on cloud-based solutions..

Pros

• Customizable and Private: Since it’s open-source, Llama 3.1 offers a level of customization that proprietary models don’t. You can fine-tune it to suit your specific needs, and since you can run it locally, you retain complete control over your data, ensuring privacy and security.

• No Web Search: Llama 3.1 doesn’t include real-time web search functionality, limiting its ability to pull in up-to-date information or fact-check live data. If your content needs to be updated regularly, you might need to supplement it with another tool that has web search capabilities.

Pricing

Because Llama 3.1 is open-source, the model itself is free to use, making it an extremely cost-effective solution. However, the costs associated with running it locally, such as hardware and server maintenance, can add up depending on the scale of your operations. 

4. Gemini 1.5 Pro

• Not the Smartest: Despite its strengths in structured output and web search, Gemini 1.5 Pro is not as advanced in handling complex reasoning tasks. If your content involves deep analysis or sophisticated problem-solving, other models may perform better.
• Censorship: Gemini 1.5 Pro can be somewhat conservative in its content generation. If your content touches on sensitive or controversial topics, it may limit the scope of what you can write.

Pricing

Gemini 1.5 Pro is available through Google’s enterprise-level services, making it more accessible to larger businesses or content teams with specific needs. Pricing details are typically customized based on usage and scale, so it’s necessary to consult Google directly for a quote.
