Getting started
ContextSage runs AI entirely on your device. Documents stay in your browser. Nothing is sent to a server unless you explicitly choose a cloud model with your own API key.
Quick start (Free)
- Open contextsage.ai in Chrome or Edge
- Select a model from the dropdown — TinyLlama or Phi-3 Mini work on most devices
- Create a matter under Docs, upload a document, and start chatting
No account required for the Free tier.
What’s a “matter”?
A matter is an isolated workspace — documents, chat history, and vector search are siloed per matter. Think of it as a client folder. Switching matters changes which documents are in context.
