FAQ
Why use a local LLM instead of cloud-based models?
Cloud models may be more frequently updated, but they come at the cost of your privacy: every query is sent to external servers. A local LLM runs
entirely on your device
— no data ever leaves your computer. You get the same smart AI, safely and privately.
How private is Sigma Eclipse?
Extremely. All computations, text processing, and query history remain on your device. We technically cannot access any of your data.
Will the local LLM slow down my browser?
No. Sigma Eclipse is optimized for modern laptops and desktops, using minimal resources without interfering with normal browser performance.
Do I need an internet connection for the AI to work?
No. Sigma Eclipse works fully offline: responses, analysis, and content generation all happen locally.
What tasks can the local LLM handle?
Almost anything cloud AI can do: — Web page analysis — Text writing and editing — Summarization and research — Coding assistance — Question answering — Idea generation And all of it stays on your device.
Can I use it for professional work?
Yes. Sigma Eclipse is ideal for sensitive work where privacy is critical — legal, corporate documents, medical data, R&D, finance, and cybersecurity.
How are the models updated if everything is local?
We provide updates that you can download manually or automatically if you prefer. No data is ever sent to external servers — only the model and performance improvements are updated.
Does Sigma Eclipse support plugins or extensions?
Yes. The platform allows lightweight plugins that operate
locally
without sending any requests to the cloud.
How is Sigma Eclipse different from open-source local solutions?
We combine everything in one system: browser, local LLM, model management, optimization, and private agent. No complicated setups, libraries, or dependencies — everything works out-of-the-box.
