★★★☆☆
Price level: Free

Ghostbuster is a free tool that can spot text written by AI. It was created by computer scientists at UC Berkeley.

Who Can Use It:

Anyone can use Ghostbuster to check if text was written by AI or a human. It's free and accessible to all, whether you're a student, writer, or just curious about online content. 

How It Works?

Ghostbuster detects AI-generated text through a multi-step process. 

It first analyzes the input text using various language models, ranging from simple word-frequency counters to more sophisticated programs like GPT-3. 

These models calculate the probability of each word in the text. 

Ghostbuster then searches for meaningful patterns in these probabilities, creating a set of distinctive features. 

Finally, it uses a trained classifier to determine whether the text is likely AI-generated or human-written based on these features. 

Key Features:

  • Identifies AI-authored content without needing access to the specific AI system that might have created it.
  • Detailed documentation available on GitHub.

Limitations and Considerations:

  • As a university project, Ghostbuster may have limited long-term support and infrequent updates.
  • Ghostbuster sends all inputs to OpenAI's API, without privacy guarantees.
  • Struggles to identify AI-generated but human modified text.
