Current capabilities, and what's coming next.
PortableRAG is a private developer preview. Here's what works today for testers, and what's still on the roadmap.
Private Projects
Private previewKeep each set of documents in its own self-contained project, so your client files, personal research, and company documents never mix.
Advanced
Each project maintains its own local index and configuration.
Local Document Chat
Private previewAsk questions in plain English and get answers drawn directly from your files — no copying and pasting into a chat window.
Source Citations
Private previewEvery answer links back to the exact document and passage it came from, so you can verify it in seconds.
Advanced
Citations reference the specific retrieved passage used to ground the answer, not just the source file.
Hybrid Search
Private previewPortableRAG looks for both the meaning of your question and the exact words you used, then combines both to find the most relevant passages.
Advanced
Combines semantic (vector) search with keyword (BM25) search, merged and reranked before being passed to the model.
Offline Use
Private previewOnce set up, use PortableRAG on a flight, in a secure facility, or anywhere without a reliable internet connection.
Local AI Models
Private previewPortableRAG runs AI models on your own computer by default, so your questions and documents don't need to leave your machine to get an answer. Configuring an external cloud model is optional and explicit.
Desktop App for macOS
Private previewA desktop application for Apple Silicon Macs — not a browser tab. Windows is planned next.
Delete Local Project Data
Private previewDelete a project any time. It's your data, stored where you can see it, removable when you're done with it.
Windows, Linux & Team Workspaces
PlannedWindows is next and Linux is planned, both with the same local-first design. Shared team workspaces are on the roadmap — PortableRAG is a single-user app today.
