Implement "Project" folders that function as a unified workspace, similar to Claude projects. - Folder-Level Knowledge: Allow users to upload "Project Files" (PDFs, docs, code) that are automatically indexed and accessible to every chat within that folder. Custom Instructions: Set a "Project Brief" or system prompt that applies to all chats in the folder, eliminating the need to repeat context. Cross-Chat Awareness: Enable the AI to reference context or conclusions from previous chats within the same project folder.
