Content True

Content True is an online text analysis tool designed to verify the authenticity of written content by identifying whether it was produced by a language model. It takes the form of a web application where users can paste text directly or upload files to receive a confidence score and a breakdown of human versus AI probability. The product is aimed at educators, editors, and high-volume content handlers who need a first-pass check to flag AI involvement in submissions or articles.

• Identifies AI-generated text from models including GPT, Claude, Gemini, Llama, and DeepSeek
• Supports text analysis across more than 50 languages with native fluency
• Provides both Quick Analysis and Deep Analysis modes
• Highlights specific sections of text that drove the AI detection verdict
• Performs deep-dive evaluations tracking perplexity, burstiness, and semantic flow
• Accepts file uploads in .txt, .md, and .docx formats
• Delivers mixed AI and human text detection alongside downloadable analysis reports

Pros

• Supports multiple leading AI language models to keep pace with newly released text generators
• Offers broad language support covering over 50 languages including English, Spanish, Chinese, and Arabic
• Provides flexible usage options through both monthly subscriptions and non-expiring credit packages
• Includes file upload capabilities for common document formats like .docx, .md, and .txt

Cons

• Free tier includes length limits per check that require upgrading to paid plans to lift
• Deep analysis options take about a minute to complete rather than returning instant results
• Requires at least 200 characters of input text for better analysis accuracy

Content True fits educators, editors, and content teams who need to evaluate text authenticity across multiple languages and major AI models. It is well-suited for organizations handling mixed AI and human text that require downloadable reports and multi-model verification. It is a poor fit for casual users who do not require bulk checks or detailed breakdowns, as well as those submitting text samples shorter than the recommended 200 characters.

Content True operates on a freemium model offering a free tier alongside monthly subscription plans and credit packages. The monthly subscription tiers include Pro at $9.9 /month (discounted from $19.8 /month), which provides 200,000 credits per month and up to 100,000 characters per scan, and Ultra at $19.9 /month (discounted from $39.8 /month), which provides 400,000 credits per month and up to 100,000 characters per scan. Additionally, non-expiring credit packages are available for purchase, including Basic (250,000 credits) at $15.9 (discounted from $31.8), Standard (650,000 credits) at $39.9 (discounted from $79.8), and Premium (1,350,000 credits) at $79.9 (discounted from $159.8).

Unlike basic wrapper tools, Content True utilizes a proprietary model built from scratch with over 100 billion parameters to evaluate text patterns. Rather than simply scanning surface-level syntax, it mirrors human reading by analyzing perplexity, burstiness, and semantic flow. It also profiles multiple leading language models simultaneously and provides native-level detection across more than 50 different languages.

Content True supports file uploads in .txt, .md, and .docx formats and works with text generated by models such as GPT, Claude, Gemini, LLaMA, and DeepSeek across more than 50 languages.

Content True is worth trying for educators, editors, and teams looking for a multi-language AI detector that covers major language models like GPT, Claude, and Gemini. The freemium model lets users test the platform for free before committing to the Pro or Ultra monthly subscriptions or purchasing non-expiring credit packages. However, users who need unlimited free scanning or an open-source solution should look elsewhere, as the platform enforces character limits on the free tier and requires paid plans for higher-volume needs.
