AI Detector by TextNavigator: strengths & weaknesses

Very low false-positive rate — you won't wrongly accuse students or writers of using AI.
Deep analysis specifically tuned for Claude and Gemini outputs, which other detectors miss.
Heatmap visualizations make it easy to show exactly which sentences look AI-written.
Fast API response times for processing large batches of documents.
No mobile app — you can't use it on your phone.
Free tier is very restrictive on word count, so you'll hit a paywall fast.
Requires high-quality source text; messy or short inputs reduce accuracy.
Pricing is not published — you have to contact sales, which is a red flag for casual users.

Frequent updates to detect newer LLM models like GPT-4o and Claude 3.5.
Supports many input formats: text, PDF, DOCX, HTML, and JSON.
No mobile app — desktop/API only.
Credit usage can scale quickly for large datasets, making it expensive for heavy use.
Occasional false positives with highly technical or dry text (e.g., legal documents).

Common questions

Can I use AI Detector by TextNavigator or TextCortex on my phone?

No. Neither tool has a mobile app. Both are designed for desktop browsers or API integration. If you need to check text on the go, look for a different tool.

Which tool is better for checking student essays for AI use?

TextNavigator is better because of its extremely low false-positive rate — you won't wrongly accuse a student. TextCortex may flag technical or dry writing as AI, which is common in student work.

Do I need to know how to code to use these tools?

TextNavigator offers a Chrome extension and web interface, so you can use it without coding. TextCortex is primarily an API — you'll need to write code or use a developer to integrate it.

How much do these tools cost?

Neither publishes clear pricing. Both require contacting sales for enterprise plans. TextCortex uses a credit system that can get expensive for large volumes. TextNavigator's free tier is very limited.

Which tool is better for detecting AI content in multiple languages?

TextCortex is the clear winner here — it has superior multilingual support. TextNavigator is primarily designed for English text.

Both tools are powerful but developer-focused — skip them if you want a simple, mobile-friendly AI detector with clear pricing.

If you're a non-technical person looking for a simple AI detector, neither of these tools is a great fit — they're built for developers and enterprise teams. TextCortex is more versatile for multilingual and bulk work, while TextNavigator is safer for avoiding false accusations. But honestly, you'll have an easier time with a consumer-friendly tool like GPTZero or Originality.ai.
