Detecting AI-generated text is becoming increasingly important as advanced systems like Claude 2 are able to produce remarkably human-like writing. In this article, we’ll put Claude 2 against current detectors and analyze their capabilities and limitations.

Claude 2 Overview

Claude 2 is an AI assistant created by Anthropic to be helpful, harmless, and honest. It uses natural language processing to generate text on a wide range of topics that simulates human writing. Claude 2 is designed to be safety-focused and avoid potential harms from uncontrolled AI text generation.

Early demonstrations show Claude 2 can write emails, articles, code, and more in a very natural style, some believe more “human-like” than ChatGPT. Its capabilities go beyond purely statistical text predictions, allowing more contextual generation. The goal is for Claude 2’s writing to be indistinguishable from a human’s in many cases.

Claude 2 versus popular AI writing detectors

A recent article published on Search Engine Journal outlines the fact that Claude 2 was able to bypass Originality’s ai detection algorithm for the following prompt: Can you write a 500-word article about SEO? 

The output was able to bypass 3 popular AI checkers, including Originality, GPTZero and Hugging Face. 

In the above example, Claude 2’s article on SEO is identified as Original. 

In this case, GPTZero’s assessment on the content was “Entirely human”.

HuggingFace’s free popular AI detection tool claims Claude 2’s essay on SEO is real.

Claude 2 vs. Winston AI

No outputs generated by Claude 2 was able to bypass Winston AI, who is re-trained with new LLM’s and updates on a weekly basis. 


Claude 2 is a serious competitor for ChatGPT with less notoriety, and will continue to gain users. Its writing style is very human and will bypass several AI checkers. However, keep in mind there is a significant difference between paid AI detection softwares and free ones. Anyone who is serious about maintaining integrity or curious about the originality of a given document should always think about choosing a premium AI checker. In all of our internal testings, Claude 2 was not able to bypass Winston AI.  


What is Claude AI and how does it compare to ChatGPT?

Claude is an AI assistant created by Anthropic to be helpful, honest and harmless. Here’s a quick comparison between Claude and ChatGPT:

Creator: Claude was created by Anthropic while ChatGPT was created by OpenAI.
Release Date: Claude was publicly released in February 2023, while ChatGPT was released in November 2022.
Training Data: Claude claims to be trained on safer data filtered to avoid harmful responses, while ChatGPT has faced some criticism over biases and inaccuracies in its training data.
Capabilities: Both can understand natural language prompts and generate human-like responses, but Claude aims to give responses that are truthful and framed helpfully.
Limitations: As an early stage AI, Claude has more limited knowledge than ChatGPT. Both can sometimes generate plausible-sounding but incorrect or nonsensical responses.

In summary, Claude takes a similar approach to conversational AI but prioritizes safety, truthfulness and transparency in areas where ChatGPT has faced criticism. As AI assistants evolve, considering ethics and social impact will be important.

Is Claude better than ChatGPT

Overall, there are good reasons why Anthropic is positioning Claude as safer and more beneficial for society. But ChatGPT is more advanced in some AI capabilities right now. The best AI assistant will need to balance wide knowledge, accuracy, safety and ethics. More development is needed to truly surpass systems like ChatGPT in a responsible way.

Can Claude 2 bypass AI detectors?

Claude 2 is extremely good at mimicking human’s writing capabilities, and bypasses most AI detection tools. Only Winston AI was able to successfully detect its outputs 100% of the time in our internal tests.
