Cross-platform AI writing assistant delivering real-time grammar correction, tone alignment, authorship tracking, and team style guides.
Works natively inside Chrome, Safari, Firefox, Edge, Windows, Mac, Google Docs, MS Office, and mobile keyboards to flag grammar mistakes, rewrite tangled sentences, and shift tone toward confident, empathetic, or executive registers.
Deploys contextual AI agents that predict how a target audience will react to a draft, locate credible supporting citations, grade essays against rubric criteria, and generate drafts using up to 2,000 monthly prompts on Pro.
Scans text against billions of web pages and academic databases for accidental plagiarism, detects AI-generated passages, and logs transparent document provenance via Authorship reports in Google Docs and Word.
Enables teams on Pro and Enterprise plans to codify company terminology, ban deprecated jargon, enforce inclusive language, insert shared Snippets, and surface internal company definitions inline.
AI document conversion for math, chemistry, tables and full PDFs
Recognises printed and handwritten math, chemistry diagrams, tables and text across many languages and returns editable output such as LaTeX, Markdown, MathML, SMILES or ChemDraw.
Screenshot any region of your screen or a web page and copy the converted math, chemistry or text straight to your clipboard with a keyboard shortcut.
The OCR API and Files API let you embed the same conversion engine in your own product, with support for Python and CLI workflows and full PDF document processing.
Convert PDFs to LaTeX, Word, Excel, Markdown, HTML or Overleaf-ready output, and images to LaTeX, AsciiMath, CSV or other structured formats.
