The sovereign AI that turns every answer into lasting expertise. Cut response times by up to 90%. Optivalue.ai automates information discovery and drafting, freeing experts for the high-impact personalization that wins bids. It acts as an expert librarian for your knowledge base: submit a questionnaire — RFP, audit, security or compliance — and get a complete, source-verified draft in minutes. Every answer is built on 89 Domain-Specific Language Models specialized by function and industry, not a generic LLM. Each answer carries a 0-100 confidence score and precise source citations (document, page, timestamp) for full traceability. When no source supports an answer, Optivalue.ai says "I don't know" rather than hallucinate. You don't just answer correctly — you prove it. It's an engine of progress for your organization. Optivalue.ai runs a gap analysis to identify weaknesses in your documentation. Following the recommendations strengthens your internal documents and builds lasting expertise across the organization. Your data stays yours: a private AI per client, never shared, deployed on-premise or in a sovereign cloud. Enterprise-grade security, compliant with GDPR, ISO 27001, HIPAA, SOC 2 and FedRAMP. All plans include unlimited users and unlimited projects. Start your 14-day free trial — no credit card, no commitment.
