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.
Detect, humanize and verify AI content in one place
Scans up to 5,000 words at a time and highlights the specific sentences most likely to be flagged as machine-written, so you can see your text the way a detector sees it.
Rewrites AI-flagged passages with different sentence rhythms, vocabulary and tone, keeping your meaning while making the prose read like human writing.
Detectors for AI images, voice recordings, video and deepfakes, plus specialty document tools for checking whether a PDF or screenshot has been manipulated.
Detect and humanize directly inside Gmail, Google Docs or any web page without switching tabs.
