Anoni helps professionals use AI with confidential documents without exposing the information inside them.
Legal teams, HR departments, healthcare organizations, accountants, consultants, and public-sector teams often cannot send contracts, CVs, case files, patient information, or client records to AI tools because those documents contain personaland sensitive data. Manual redaction is slow, error-prone, and can make a document difficult to use.
Anoni solves this by processing documents locally on the user’s machine. It detects personal and confidential information, then anonymizes, pseudonymizes, or redacts it before the document is shared, analyzed, or used with AI. Documents are not uploaded to a cloud-processing service.
Anoni is built in France for privacy-conscious AI, document review, collaboration, and data-preparation workflows. It includes local processing, configurable detection, realistic pseudonymization, and locally generated reporting.

nilGPT
nilGPT is a privacy-focused AI chat companion that emphasizes secure, anonymized interaction. It claims that all data is handled with “data private by default”, your chat inputs are split and stored across multiple nilDB nodes, and AI models run inside secure enclaves, so your data isn’t centrally exposed. nilGPT offers specialized conversation modes (such as wellness, personal assistant, companion) to adapt to different use cases. It positions itself as a place where users can “talk freely” about sensitive thoughts or personal topics without fear of log retention or surveillance. It provides both a browser chat interface and app access, with options to sign in or chat anonymously. According to its GitHub repo, nilGPT is built using “SecretLLM + SecretVaults” and is open source under the MIT license.
