AI Response Quality

Inventive AI

Inventive AI is an autonomous AI agentic platform that generates responses from connected company knowledge instead of relying solely on a maintained content library. Every response includes source citations and confidence scores, while built-in content governance flags unsupported or conflicting information before review. When supporting information isn't available, the platform surfaces the gap instead of generating an unsupported answer.

For example, RAD AI reported 2× more client-ready responses, while Insider reduced a 100-question RFP from 4–5 hours to 20–30 minutes after adopting Inventive AI. 

Arphie

Arphie generates AI-assisted responses using your proposal content and connected knowledge sources. It also provides source citations to help reviewers verify answers, making it easier to validate generated content before submission. Teams remain responsible for reviewing and refining responses before they're finalized.
