Compare Nonimo vs. Velum Privacy

Nonimo enables teams to leverage generative AI while managing client and personal data securely. Its applications for macOS and Windows are designed to identify sensitive information in chosen text, substituting it with labels prior to the text being transmitted to any AI tool; users have the ability to revert to the original data when retrieving responses. Additionally, a complementary extension integrates seamlessly with ChatGPT, Claude, and Gemini in both Chrome and Safari. Beyond text, the applications can also redact sensitive information from Word, Excel, PowerPoint, PDF, OpenDocument, and various other file types before they are uploaded, while browser tools facilitate the masking of fields in identification documents. Text analysis is conducted locally, ensuring that it can function without an internet connection. Organizations have the capacity to deploy these browser extensions through policy settings and can generate signed usage reports for monitoring purposes. Nonimo Gateway acts as a distinct self-hosted API proxy currently in pilot, catering to applications that utilize AI APIs; it effectively masks sensitive data in outgoing requests and restores it in responses. The platform is tailored to meet the needs of professional sectors such as law, accounting, healthcare, insurance, and public service, all of which routinely manage sensitive client or personal information. With Nonimo, teams can work with confidence, knowing their data is safeguarded throughout the process.

Velum Privacy is designed to protect personal data before it interacts with an AI assistant, subsequently restoring the actual values in the response, all while operating solely on your machine without the need for servers, accounts, or any telemetry. The system is inherently reversible; it employs one-way redaction to secure the data, although this would typically compromise the response, yet a local mapping ensures that the returned reply remains intelligible. This solution comprises three distinct interfaces integrated into a single engine: a browser extension compatible with Chrome, Brave, Edge, and Vivaldi that offers text masking without requiring an account; a macOS desktop application that manages documents, folders, and coding tasks through MCP, with a Windows version currently under development; and an application for Jira and Confluence Cloud that operates within your own Atlassian environment. Detection is achieved through a combination of pattern recognition, checksum validation specifically for IBANs and national IDs, and a local named entity recognition model that supports nine language variations, with published accuracy metrics highlighting a remarkable 99.8% must-mask F1 score at the highest level, including failure rates. The commitment to transparency is evident, as the extension specifies zero host permissions, while the desktop application meticulously lists every outbound connection and ensures masking occurs even when the network is offline, reinforcing the integrity of the system. Such comprehensive measures ensure that users can maintain control over their sensitive information while enjoying the benefits of AI technology.
