SAN FRANCISCO, CA – 25/12/2025 – (SeaPRwire) – As concerns over data security and centralized AI infrastructure continue to grow, Sigma Browser has introduced Sigma Eclipse, a local-first AI browser designed to give users direct control over how artificial intelligence interacts with their data. Unlike cloud-dependent AI browsers, Sigma Eclipse operates entirely on the user’s own machine, eliminating the need to transmit personal information to external servers.
By running its AI engine locally, Sigma Eclipse ensures that browsing history, credentials, documents, and task-related data remain on the device at all times. The architecture removes reliance on cloud processing, allowing users to access AI-assisted browsing tools without exposing sensitive information to third-party infrastructure.
According to Sigma Browser, this approach makes privacy observable rather than implied. The browser’s AI chat functions offline, and its open-source codebase allows independent developers and security experts to examine how data is handled. This transparency is intended to address growing skepticism around closed AI systems that offer limited insight into data flows and internal processes.
Sigma Eclipse also includes an unrestricted language model that does not impose ideological filters or topic-based limitations. The company positions this design choice as a way to preserve user autonomy, enabling individuals to engage with AI tools without externally defined boundaries on subject matter or perspective.
Additional functionality includes local PDF processing, allowing users to analyze documents directly on their computer. Because files are never uploaded to remote servers, the feature is positioned for use cases involving legal, financial, professional, or personal documents that require strict confidentiality.
The browser’s creators emphasize that eliminating cloud infrastructure also removes ongoing cloud-processing expenses. As a result, Sigma Eclipse’s local large language model is available to users at no cost, without subscriptions or usage fees tied to core AI functionality.
Sigma Browser describes the release as part of a broader effort to promote a more decentralized AI ecosystem—one where performance, privacy, and accessibility can coexist. The company argues that local-first AI models offer a practical alternative to cloud-reliant systems, particularly as users become more sensitive to long-term costs, data ownership, and surveillance concerns.
