Is open-os LLM Browser Extension safe?
open-os LLM Browser Extension sends chat prompts and configured persona text to the selected Ollama endpoint.
When you use the extension's chat UI, it posts the selected model and message history to an Ollama-compatible /api/chat endpoint. The message content can include text you typed plus stored pre-prompt or identity/persona text, and the endpoint defaults to localhost:11434 unless you configure another Ollama host.
