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.

Naix
Naix is AI-powered anonymization and redaction tool designed to remove personally identifiable information from documents quickly, accurately, and securely. It combines machine learning, natural language processing, and linguistic models to detect company names, legal forms, personal names, countries, cities, streets, email addresses, URLs, dates, IDs, graphics, monetary sums, and other amounts. It supports PDFs, Word and Excel files, emails, scans, and image formats, with language models for English, German, and French. Naix automates most of the anonymization process while retaining manual redaction tools for reviewing remaining exceptions. Users can also apply predefined pseudonyms to preserve context where full anonymization is not appropriate. Its simple interface supports the workflow from uploading a document to reviewing findings and creating a secure output file.

SecuredAI
SecuredAI is a privacy-first AI assistant that protects sensitive information before it is sent to large language models such as OpenAI and DeepSeek.

Its Zero-Knowledge Vault ensures that sensitive information never leaves the device and that encryption keys are never stored on SecuredAI's servers.
