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.

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.

Scan exported images and PDFs to surface potential spelling, grammar, punctuation, consistency and translation errors in the visible copy.
Upload a design brief alongside the artwork so Gard can check offers, prices, dates and mandatory copy against your requirements.
Each correction is shown in context with Confirm or Ignore options, so reviewers stay in control of what actually changes.
Share scan corrections by link and export a corrections PDF, so QA, design and marketing teams can collaborate and sign off faster.
