Noema

Noema is a local AI assistant for people who want to chat with models and get answers from their files on Apple devices. It brings models, documents and tools into a native workspace on iPhone, iPad, Mac and Vision Pro.

• Local models: Use GGUF, MLX, Core ML, ExecuTorch and Apple Foundation Models in the same app.
• Answers from files: Read PDFs and retrieve relevant material from your own datasets, with retrieval running on your device.
• Tools and evidence: Search the web, open supporting evidence, inspect citations and connect MCP tools when a task needs outside resources.
• Task modes: Choose Chat Only, Agent, Plan or Review mode while keeping tool permissions visible.
• Across-device access: Constellation syncs chats, projects and tool history across Apple devices and lets an iPhone or iPad use a model installed on an awake Mac.

Local chat doesn't require a cloud service, and chats can remain on your device. Optional network access has visible controls; Off-grid Mode blocks external HTTP and HTTPS connections. Web search requires network access.

When Constellation uses a Mac's model, inference stays on that Mac and requests and replies travel between devices. Noema also includes Mac projects and study tools.
