Ensis

Ensis is an AI productivity tool for knowledge workers that works inside Microsoft Word, Excel, PowerPoint and Outlook. It connects to a company's verified knowledge base and the open web so that drafts and answers draw on approved content, and it can be hosted wherever the customer needs. Its main use is proposal and RFP work. It can analyze an RFP to surface requirements, turn a solicitation into a structured outline, generate proposal sections from approved past submissions and check a draft against the RFP instructions. In Excel it fills out questionnaires and assessments from company knowledge, in PowerPoint it drafts slide decks and speaker notes, and in Outlook it summarizes threads, drafts replies in company language and extracts action items. Proposal, sales, operations and technical teams share one connected knowledge base. The vendor positions it as a faster alternative to Copilot. The site states that Ensis is now part of Arkenstone, a product for AI proposals and federal and defense contract responses. Pricing is not published, and access is through a demo request.
