What IA Checker is
IA Checker is an iOS and web workspace for checking AI-generated text and images, revising writing, and labelling AI content under the EU AI Act. Its text detector combines authenticity signals and indicates sentence by sentence what informed its analysis. The service says about 60 words are needed for a useful reading and about 200 for a confident one. Writing tools include paraphrasing, grammar checks, translation, summaries, and AI humanization. It can extract text from PDF, DOCX, and plain-text files, using OCR for scans, with a 20 MB upload ceiling. Image analysis accepts JPG, PNG, and WebP files up to 15 MB, but requires a signed-in Pro or Max account. Pasted-text detection runs locally in the browser. The free plan includes text detection and writing tools; Premium is €14.90 a month or €118.80 a year. Writing operations draw on word credits, calculated from input size and tool multiplier, with monthly UTC resets. Optional text history is off by default; the service says it does not sell submissions or use them for training without express opt-in. A self-serve public API is being designed and is not generally available.
