Question 1

What is the best AI detector for teachers?

Accepted Answer

A good AI detector for teachers gives a clear score, works on any assignment length and doesn't need a setup. The free StealthGPT AI Detector scores pasted text from 0 to 100 for how likely it is to be AI-generated. Schools and edtech companies that want detection inside their own tools can use the same detector through the StealthGPT API.

Question 2

How should teachers read an AI detection score?

Accepted Answer

Treat the score as a signal, not proof. On StealthGPT, 0-30 means likely human, 31-70 means mixed signals, such as heavily edited or partly AI-written text, and 71-100 means likely AI-generated. Short pieces under about 50 words and templated writing can give noisy scores, so check full paragraphs and talk with the student before drawing conclusions.

Question 3

Can I add AI detection to an LMS or edtech platform?

Accepted Answer

Yes. Edtech and LMS teams can call POST /api/stealthify/detect from their own platform with an api-token and show the 0-100 score next to each submission. Each request accepts up to 50,000 characters, works in any language, and returns the words spent and remaining credits, so you can track usage per school or course.

Question 4

Does the AI detector work for essays in other languages?

Accepted Answer

Yes. The StealthGPT detector is language-agnostic, so essays and assignments in any language go through the same endpoint with no extra settings. Teachers get the same 0-100 score bands for every class, and edtech platforms that serve schools in several countries can use one integration instead of a separate detector for each language.

Question 5

How much does the AI detector API cost for schools and edtech?

Accepted Answer

The free AI Detector on stealthgpt.ai costs nothing for individual checks. The AI Detector API bills one word per input word, so a 1,000-word essay uses 1,000 words. It's included in the Build, Grow and Scale API plans, which start at $19 a month, and our sales team can set up higher monthly limits for platforms with many schools.
