Our verdict on IA Checker
IA Checker is a web-based AI detection suite for writers, educators, publishers, and professional content teams. It analyzes pasted text and uploaded documents, while also supporting public URLs, websites, images, and video. Results include AI probability, writing signals, and sentence-level review. The wider toolkit covers plagiarism checking, AI text humanization, writing tools, EU AI labeling, detection history, and PDF report export on Pro and Max. Its scope suits users who need more than a single text detector and want one browser-based workspace for different content formats.
The product’s main strength is breadth combined with useful review detail. Sentence-level analysis can help readers locate detected passages rather than relying only on an overall result. Document uploads support PDF, Word, and other formats, while website checking extends the workflow beyond pasted copy. Image and video detection add media coverage that is less common in text-focused workflows. However, the service remains web-only, and media allowances vary by plan. The public developer API is not generally available, although API access is listed for Pro and Max, with private business integrations discussed separately.
The Free plan includes free detection checks, 20,000 characters per check, AI Detector access, EU Labelizer access, one short document upload, and three quick image checks. Plus raises the limit to 75,000 characters and adds 300,000 monthly word credits, Advanced Humanization, all writing tools, and detection history. Pro adds 1,000,000 monthly word credits, 150,000-character checks, 10 media checks per month, document uploads, website checking, all detection tools, and PDF reports. Max expands usage to 3 million monthly word credits, 30 media checks, and 8,000 Undetectable AI words per month. Choose IA Checker for varied content review; choose a narrower tool if you only need basic text checks.
