WriteWise AI Detector

GPTZero

Best overall

GPTZero is the better choice for most everyday users because it's free to start, works in your browser, and is built for quick AI detection. WriteWise is a full academic writing workspace, not just a detector, and its $19/month price tag only makes sense if you're a researcher writing papers. The single biggest difference: GPTZero is a lightweight AI checker anyone can use; WriteWise is a heavy-duty academic tool for scholars.

Common questions

Is WriteWise AI Detector better than GPTZero for checking student essays?

No, GPTZero is better for student essays because it's free, works instantly in your browser, and has a Google Docs add-on. WriteWise is overkill and expensive for that use case.

Can I use GPTZero on my phone?

No, GPTZero doesn't have a mobile app. You can use it in a mobile browser, but the experience is not optimized for small screens.

Does WriteWise detect AI from ChatGPT and Gemini?

Yes, WriteWise claims to detect content from the latest LLM releases (2025-2026), including ChatGPT and Gemini. GPTZero also detects those models plus Claude and Llama.

Which tool is more accurate at detecting AI writing?

Both claim high accuracy, but GPTZero cites independent benchmarking showing best-in-class results. WriteWise focuses on academic writing and may have fewer false positives on research papers but more on technical writing.

Do I need to pay for GPTZero?

No, GPTZero is free for up to 10,000 characters per scan. Higher usage limits require a paid plan, but pricing is not clearly published on their website.

Can WriteWise check plagiarism too?

Yes, WriteWise combines AI detection and plagiarism checking into one PDF report. GPTZero also offers a plagiarism checker as part of its scan.

GPTZero wins for everyday AI detection (free, fast, easy); WriteWise is for serious academic researchers who need a full writing suite.

If you just need to check if something was written by AI — a student essay, a blog post, an email — start with GPTZero. It's free, fast, and works in your browser. Only consider WriteWise if you're writing academic papers for journals and need a full workspace with deep forensic reports, and you're okay paying $19/month.
