Show HN: ChatPanel, A Privacy-first AI Agent browser side panel (chatpanel.net)

ChatPanel has launched a privacy-first AI agent that operates as a browser side panel, allowing users to interact seamlessly with their AI models without leaving their current webpage. This tool works offline, installing a private model directly in the browser, enabling users to chat about the content on the page, their meetings, or any tools they use—all while ensuring that no data leaves their machine. Compatible with Chrome, Edge, Brave, and Arc, ChatPanel supports multiple AI models, including Claude Code and Codex, and offers one-click integration with various tools. This development is significant for the AI/ML community because it emphasizes user privacy and control in an era where data security is increasingly vital. ChatPanel allows for reversible redaction of personal information and keeps all interactions local to the user’s device, which presents a novel approach to maintaining confidentiality while leveraging powerful AI capabilities. The application also supports dynamic functionalities like transforming live captions from conferencing tools into searchable notes and action items, making it a versatile solution for productivity enhancement in professional environments. Overall, ChatPanel is positioned to empower users with more control over their interactions with AI while prioritizing privacy.
