What are Project Files?
Project files are documents and other resources you upload directly to a project. Unlike files attached to a single chat, project files are available as context in any chat within the project — you upload once, and all project chats can reference them. This is useful for reference materials that multiple conversations need: a codebase overview, a style guide, a data dictionary, a product spec, or background research.Adding Files to a Project
1
Open the project
Click the project name in the left sidebar.
2
Go to the Files tab
In the project view, click the Files tab (usually in the project header or sidebar).
3
Upload files
Click Upload or drag and drop files into the Files area.Supported file types are the same as standard ZeroTwo file uploads: PDF, DOCX, TXT, CSV, XLSX, images, code files (.py, .js, .ts, .json, etc.), and more.
How ZeroTwo Uses Project Files
Project files are available as background context, but ZeroTwo doesn’t automatically read every project file for every message. To use a project file in a chat:- Mention it explicitly: “Using the product spec I uploaded, write a feature summary for the landing page.”
- Reference its content: “Based on the API documentation file in this project, what’s the correct endpoint for creating a user?”
- Ask ZeroTwo to consult it: “Check the brand guidelines file and rewrite this paragraph to match our tone.”
