Asthra AI
by Sangnan AI
AI co-author that drafts source-grounded, fully cited regulatory documents inside Microsoft Word.
Asthra AI brings an AI drafting agent into Microsoft Word for regulatory and clinical writing teams in life sciences. Give it your approved source documents and it produces structured, source-grounded first drafts — with a citation behind every claim.
What Asthra does
- Drafts from your sources, not general knowledge.
- Cites everything — traceable to the source document, section, and page.
- Flags gaps inline instead of inventing content, then re-scores as you resolve them.
- Runs on-request regulatory checks and lists concrete findings.
- Keeps a full, exportable audit trail.
You stay the author. Drafts are AI-generated and every claim cites a source; you review and approve before anything ships.
Enterprise product — account required. Asthra AI is organization-deployed. It requires a separate Asthra account (not your Microsoft 365 sign-in), provisioned by your administrator, and a paid Asthra subscription. Request a demo or trial at asthra-writer.ai.
Data handling. Only content you select or generate in the active Word document is read (via Office.js), sent over HTTPS to the Asthra service, not retained beyond the session (except the audit trail embedded in your document), and never used to train AI models. The add-in does not access your mailbox, calendar, or OneDrive. See asthra-writer.ai/privacy.
