Redact documents 98% faster with AI-powered PII detection
Automatically identify names, social security numbers, credit card numbers and other sensitive data across documents and images, with suggested redactions you can review and approve.
Redactions are applied to the file itself rather than overlaid, so hidden text cannot be recovered through copy-paste, text selection or metadata inspection.
Process scanned documents, photographed pages and image-based PDFs with the same automation available for native digital files, without a separate OCR step.
Every redaction and review action is logged automatically, giving compliance and legal teams a verifiable record without maintaining manual logs.

Free GLM-powered assistant that turns prompts into slides, sites and code
Describe your topic and Z.ai drafts a slide deck with structured layouts, headings and visual placeholders you can refine with follow-up prompts.
Paste a brief or a bug report and it will produce code in common languages, and it can scaffold functioning web pages and small full-stack apps.
Chat, brainstorming, rewriting, translation and summarising all run through the same prompt box, with GLM Flash models keeping responses quick.
Ask a question and it can ground the answer in web sources rather than relying only on its training data, useful for current facts and comparisons.
