Questa AI
Questa AI is a privacy-focused platform that enables organizations to safely analyze sensitive data using any large language model of their choice. It works by locally anonymizing documents through a proprietary NLP-based redaction system before any AI processing occurs. Users can upload Word, PDF, or Excel files, redact confidential information, and then generate insights or analytical reports securely. The platform allows businesses to chat with its assistant, Novara, or run custom and pre-built report templates across finance, sales, marketing, and operations. Because data is anonymized before analysis, it prevents AI providers from training on sensitive information. Questa supports both cloud deployments for small teams and self-hosted enterprise installations for full infrastructure control. By combining anonymization, analysis, and workflow automation, it helps organizations extract value from data without compromising security or compliance.
