Welcome
See what runs locally: on-device indexing, a 14-day full trial, and MCP for your IDE.
Add documents
Drop files or folders into your knowledge base — indexing starts on your PC right away.
Connect your IDE
Enable inbound MCP and register Cursor or Claude Desktop so agents can search your docs.
Then trust what comes back
Answers are checked, not just retrieved
Every passthrough reply is scored against the chunks Terran injected — grounded, weak, or unsupported.
One corpus per project
Namespaces keep client work, internal wikis, and side projects apart. Agents search only what you point them at.
Your documents stay on your PC
- Local-first on your Windows PC — the knowledge base stays with the app you install.
- Documents are indexed on-device; optional web search, chunking LLMs, and external tools are opt-in.
- Management API and inbound MCP ship with bearer-token auth enabled by default.
Pair it with Aura Wire AI Command Center
Wire’s Terran stage injects the best chunks from this corpus into every VS Code chat — no re-pointing each IDE. Included with any paid Terran license.

Aura Terran Knowledge is a Windows desktop app. You can buy here and we'll email your key, but most people start the free trial on their PC first.
14-day full trial starts on first launch — no key, no card. After the trial: limited evaluation mode — one knowledge base, up to 3 root folders, inbound MCP only; nothing is deleted

Questions
How long does setup take?
Most people are searching their first documents within minutes. Download the Windows installer, launch the app, create a namespace, and drag in a folder. On-device embeddings work out of the box — no Docker, Python environment, cloud account, or API keys required. Optional MCP setup for Cursor is one stdio command copied from Settings.
Is my data uploaded to Bitfield Creek Labs?
Aura Terran is a local-first desktop app. Your documents are indexed locally unless you explicitly configure remote model providers, web search, or external tools — those may send relevant request data to third parties.
How do I connect Cursor or Claude Desktop?
Enable the inbound MCP server in Settings and paste the stdio bridge command into your MCP client config. Agents call rag_search against your indexed corpus — the same hybrid retrieval pipeline as the built-in Search UI and Management API.
Do I need OpenAI or Ollama?
No for core search. Embeddings run on-device by default (ONNX Runtime), and hybrid retrieval works without any external model. OpenAI-compatible or Ollama endpoints are optional — for an ingest-time Chunking LLM under Settings → Chunking, optional Ollama embeddings, or LLM Passthrough upstream forwarding. At answer time you can also call rag_search / Management API and inject chunks into whatever chat model your client already uses.
What file formats can I ingest?
Aura Terran indexes common document and code formats: PDF, Word, Excel, CSV, HTML, Markdown, plain text, and typical source and config files (JSON, YAML, and more). Add individual files, whole folders, or drag-and-drop from Explorer.
What happens when the trial ends?
Nothing is deleted. The app drops to a limited evaluation mode — one knowledge base, up to 3 root folders, and the inbound MCP server — so your index and IDE connection keep working while you decide. One one-time purchase of Aura Terran Knowledge ($49) restores everything the trial unlocked.
Is Aura Terran a subscription?
No. Every install starts with a 14-day trial of the whole product — no card. After that, one one-time purchase — $49 — keeps everything for the current major version. Future major upgrades may be paid, with discounts for existing paid customers.
Can Aura Terran work offline?
Yes for core indexing, on-device embeddings, and search. Paid licenses work offline when a valid stored license exists. An optional Chunking LLM needs network access if you point it at a cloud API; local Ollama chunking works offline. Optional web search blending and remote providers require network when configured.
