TrustAI Office Assistant

TrustAI brings powerful AI assistance directly into Microsoft Word. Chat with leading models, generate or rewrite text in place, summarize long documents, translate to any language, and apply edits with one click.

KEY FEATURES

Two modes that match how you work: Chat mode for questions and analysis without changing your file. Edit mode for AI-generated rewrites where every change arrives in a review panel to accept or reject individually.

Context that understands your document: Send the current selection or the entire document with one toggle. TrustAI reads paragraphs, headings, tables, and formatting so responses respect your document structure.

Best-in-class model lineup: Powered by frontier models from OpenAI (GPT-5) and DeepSeek, with additional providers for enterprise (Azure OpenAI, Google Gemini, Anthropic Claude). Switch models per task without leaving Word.

Track Changes friendly: Apply AI edits directly or as Track Changes. Accept, reject, or undo any individual change.

Multilingual interface: English and Vietnamese UI, with AI replying in any language you ask.

Built for professionals: Contracts, reports, proposals, policy documents, research. Selected text, full-document context, table generation, and diff-based edits are all handled inside the task pane.

Works everywhere Word works: Word for the web, Word on Windows (2019+ and Microsoft 365), Word on Mac, and Word on iPad.
