Projects
Use Projects to organize conversations, ground answers in your data, and work on specific topics. Each Project acts as a container with its own files, chat history, and model set.Add the name that will be used for the project
Add files
Attach files to your project to provide source material that will be indexed and used in your chats. nexos uses Retrieval-Augmented Generation (RAG) to pull relevant context from your files when responding.
Supported file types: csv, xls, xlsx, json, docx, doc, pptx, ppt, txt, xml, tiff, pdf
File size limits: Up to 30MB per file
Vectorization: Files are chunked, embedded, and stored securely in your project’s context index
Only use trusted models when working with sensitive or proprietary content. While files stay scoped to your project, responses depend on the model’s ability to handle data securely.
Model selection & chat
You have full control over which model powers your conversation.
Select from available LLMs (OpenAI, Anthropic, Mistral, etc.)
Use the “Model Settings” dropdown inside each chat
Switch models anytime to compare outputs or adjust cost-performance tradeoffs
Begin your conversation
Enter your prompt in the chat interface. Use files (click "+ Add file") to enhance results with current information. Upload images (click + sign) to include additional context in your conversation anytime. See example below:

Sharing
Projects can be shared with teams or users.
View access – others can see and use the Project without changes
Edit access – collaborators can update files, settings, and structure
This makes Projects a shared workspace, so everyone works from the same context.
