What is IsGen.ai?
IsGen (isgen.ai) is a multilingual AI content detection tool. Its Chinese website titles itself "The Most Accurate Chinese AI Detector". It stands out from most detectors that only support English: the official states that it supports more than 80 languages, and its detection process takes two steps—first conducting an overall scan, then analyzing sentence by sentence, and finally providing a percentage breakdown of human-written, AI-generated, and hybrid content. The official also mentions a design choice: when the result is uncertain, the algorithm defaults to classifying it as "human-written" to reduce the impact of false positives on students. The website claims that over 80% of its users are students and teachers. In addition to detection, the platform also offers plagiarism detection, grammar checking, AI humanization tools, AI editors, and batch scanning.
Who is it for?
- Students and researchers who want to check the proportion of AI-generated content before submitting homework or papers
- Teachers and school administrators who need sentence-by-sentence evidence before deciding how to communicate with students
- Editors and localization teams who create multilingual content and find that English detectors often fail
- Media outlets, bloggers and corporate content teams that need to confirm originality before accepting manuscripts
- Scenarios where a report trail is required, such as submissions, audits, and internal reviews
Key features
6AI Detector
Just paste the text or upload a file. The free input box has a limit of 5,000 characters. The official states that the training samples cover the outputs of models such as GPT-5, ChatGPT, Claude, Gemini, DeepSeek, Llama, Mistral, Grok, Qwen and Microsoft Copilot.
Sentence and Phrase Analysis
The result page allows switching between two granularities. It uses color coding to mark which sentences are AI-generated, mixed, or human-written, and provides an AI influence score for each sentence, making it easy to scroll through and troubleshoot.
Multilingual Detection
Officially claims to support over 80 languages, with models trained separately for each language, and Chinese is highlighted as the top priority in its promotion.
Plagiarism Detection & Grammar Check
The official website lists these two features as supplementary to the advanced AI detector, with the former checking for duplicate content and the latter proofreading spelling, grammar and punctuation.
AI Editor & Humanizer
The platform provides an editor that allows you to check the AI score in real-time during the writing process, as well as an AI Humanizer; the official website states that you can try drafting, editing, proofreading and humanizing without registration.
Report Generation & Batch Scanning
The official claims that detailed reports can be generated based on the detection results, and batch file uploads and batch scanning are supported.
How to use IsGen.ai
- The free version has a 5,000-character input limit, which is suitable for testing a single paragraph first.
- For long texts, it is recommended to split them by chapter.
- Excessively fragmented text will make the statistical features unstable and the scores distorted.
- When checking the results, don't just look at the total score.
- switch to "Detailed Analysis" to view the sentence and phrase-level highlights, so as to pinpoint which sentences boosted the AI score.
- The official claims a baseline accuracy rate of 96.4% and a false positive rate close to 0%, but this is self-reported data, and any detector has errors.
- Important judgments must be manually reviewed.
- The official pricing page shows three annual billing tiers: $8 per month (Academic Edition), $15 per month (Writing Edition), and $24 per month (Ultimate Edition), each with different word counts and features, and the prices are promotional rates that may be adjusted at any time.
- If your school requires the use of institutional tools like Turnitin, IsGen can only be used as a self-check reference, as their algorithms and databases are different.
