Turn any PDF into editable, translatable, searchable knowledge
Convert PDFs and scans into editable .docx files that keep page size, columns and image placement, with formulas editable as native Word objects.
Recognise math formulas into LaTeX, image tables into XLSX and document code blocks, so technical and scientific material stays usable.
Translate full documents while keeping the original layout, exporting either translation-only or side-by-side bilingual PDFs.
Ask questions across several uploaded documents and get answers with citations back to the source pages for verification.
AI detection and writing verification built for schools and editors
Paste text or upload a document and get an overall AI probability score plus a sentence-by-sentence breakdown of which parts look machine-written.
Flags AI text from major model families including ChatGPT, Gemini, Claude, Llama, and others, rather than training for a single model.
A Chrome extension and Google Docs add-on bring scanning into Gmail, Docs, Classroom, and other surfaces you already work in.
Checks content for copied passages from outside sources so you can separate AI-generation questions from originality questions.
