Gemini vs Claude vs Chat GPT for Writing: Which is Best?

AI writing tools are huge right now, and there are three giants reigning supreme: Gemini, Claude and Chat GPT.

These tools – otherwise known as Large Language Models (LLMs) – use artificial intelligence to answer user queries and produce high-quality written content.

The three platforms are quite different, and they all have their place with the right audience. However, if you’re a content creator or small business, using the appropriate LLM for your needs will impact the quality, efficiency and relevance of your writing as well as how much it engages your audience.

So, let’s compare these three models – Gemini vs Claude vs Chat GPT – for writing and evaluate their strengths and weaknesses for different use cases, with the aim of finding the right tool for you!

We’ll also introduce a fourth option, Phospho. Phospho is an AI analytics platform that can help you measure the performance of different LLMs, so you can use data-driven insights to decide which tool to use to optimise your online content.

Gemini vs Claude vs Chat GPT for Writing: An Overview

Gemini was recently developed by Google Deepmind to power a range of applications and provide text, image, audio, video and code. It has three main versions – Ultra, Pro and Nano – and can be integrated with other Google services.

Claude was created by Anthropic and excels in text-based tasks such as writing documents, summarizing complex information and answering questions. It is an ethical, human-centered AI tool with a focus on producing coherent, contextually relevant outputs, as well as user safety.

Chat GPT by OpenAI is the most popular AI tool to date. It can be used as an AI search engine and content generator for casual and business users, and it integrates with Microsoft products. It has released several model variations, including GPT-3.5 and GPT-4.

Each of these models was designed with different goals and strengths in mind, making them suited to particular writing purposes. We’re going to look at their key features, strengths and weaknesses now – but if you prefer to make data-driven decisions, you can take this further by conducting a performance-based analysis with Phospho.

Comparing Writing Performance

Content Quality and Creativity

Gemini can generate strong and engaging narratives about nuanced topics and handle complex questions and tasks. If you need a tool that excels in storytelling or matches your brand tone of voice, Gemini could be a good fit.

Claude specializes in clarity and coherence, as well as using expressive and natural language. It is best used for tasks that require concise, structural outputs like informational articles and listicles, but it lacks the depth and creativity of Gemini.

Chat GPT is used widely as a search engine, but it can be used for a whole range of tasks – from writing blogs to creating social media posts. It balances creativity and coherence, making the perfect middle-ground tool between Gemini and Claude, but it does sometimes use overly wordy language, so it’s not as concise as Claude. Users have also reported that the writing style is often dry and academic, with a smaller context window.

Factual Accuracy

Gemini excels in factual accuracy as it can leverage Google’s extensive data resources. It can be limited in terms of niche or highly specialized content.

Claude is best known for contextual relevance and logical consistency, meaning it rarely generates factual errors – and when it does, it can self-correct. It is not great at reasoning or deduction, however.

Chat GPT offers knowledge across lots of different domains, but it is sometimes prone to presenting incorrect information, although the latest versions (GPT-4) supposedly include mechanisms to reduce factual errors. If you’re looking for highly accurate content, Gemini and Claude have an edge over Chat GPT.

User Customization and Flexibility

Gemini works well for creative prompts. It does offer quite a lot of customization in terms of content creation, but it’s not the best tool for highly structured content.

Claude is ideal for content that follows a strict format or has specific requirements. It works best with structured and rule-based outputs and is the most consistent tool of the three.

Chat GPT offers advanced customization options, making it pretty adaptable to multiple writing styles and formats. This tool provides the most flexibility in terms of prompts, as it can adapt to a range of use cases.

Long-Form Content Capabilities

Gemini is good at sustaining narrative flow but it does lack depth when generating lengthy informational content, such as long-form articles.

Claude stays on topic throughout longer outputs, making it the strongest choice for long-form articles and technical writing where coherence is important.

Chat GPT performs fairly reliably for long-form content requests, but it does sometimes use overly wordy, verbose language. Newer models (GPT-4) are better at handling long-form prompts and produce better, more concise content than previous versions.

Ethical and Safety Considerations

Gemini was developed using Google’s strong ethical framework, so it prioritizes safe and responsible use.

Claude has also been built explicitly with a safety-first approach, making it the best choice for content creators wanting to avoid controversial or potentially offensive language.

Chat GPT implements content moderation filters well, but it occasionally produces biased or inappropriate content in edge cases. Claude or Gemini are the best tools for businesses and creators concerned with safety and ethics.

Which Model Should You Use for Your Writing Task?

Creative Content

For branded and storytelling content – such as copy for your website or newsletter – we recommend Gemini due to its emphasis on narrative. Gemini also uses highly engaging language which will keep readers entertained.

Technical Documents

For technical writing like API documentation and product information, we recommend Claude due to its ability to produce clear, structured and factual content.

Content Marketing

ChatGPT is a great tool for general content marketing tasks like blog articles. It provides versatile writing that can suit a variety of different content types. Just remember to monitor your outputs, particularly with earlier versions of the tool, if you’re concerned about the use of sensitive language.

Customer Support

For customer support documentation or other external comms, Claude is the best tool due to its clear, instructional output style and ability to produce coherent copy.

Social Media Copy

Chat GPT can also be used to create quick, engaging and highly adaptable social media content for a variety of different industries.
