Aura Terran, All sources. One table for the project: README.md, architecture.pdf, a web page, a folder, a OneDrive library, a mailbox, a Dropbox folder, a GitHub path, and a website. Nine sources, 127 documents, 692 chunks, each with its status and last activity.

Every source for a project in one table. Screens on this page use sample data.

Try it in two minutes

Install the extension. Click Aura Terran in the activity bar, or run Open Aura Terran from the Command Palette.
The first run downloads the Terran server for your computer (100 to 130 MB) and starts it. Later runs start in a few seconds. There is no Docker, no Python environment, no API key, and no account.
Add a folder, or click Sample data at the top right to load a small demo project.
Ask the chat in your editor a question. Terran has already registered itself there as an MCP server, so the agent can search your index and name the file each passage came from.

What the agent gets back

You ask: How many requests per minute does the Meridian API allow?

The agent calls rag_search. Terran returns, from meridian-api-guide.md:

Each service account gets 600 requests per minute, measured in a sliding window. Exceeding it returns 429 with a Retry-After header in seconds. The limit is per account and not per token, so issuing extra tokens does not buy extra quota.

The agent writes its answer from that passage and can point you to the file.

This is the top result Terran returned for that question on the built-in sample data. Load Sample data and ask it yourself.

One index, every chat

Aura Terran Vector Store. Five documents and 107 chunks: two local files, one folder, one OneDrive document, and one web page. Each row shows its source, type, status, last update, and chunk count.

This sample project mixes local files, a folder, a web page, and a OneDrive document.

Add a source once and every chat in the editor can search it. Watched folders pick up later edits. A network share that drops offline keeps its index until it comes back.

PDFs, Word, PowerPoint, Excel, Markdown, HTML, and code all land in the same index. On Windows, scanned PDFs and images are read with the built-in OCR. Text is split into passages (Terran calls them chunks) and indexed on your computer, so search needs no OpenAI or Ollama key.

One index is enough. Claude Desktop and other MCP clients can use the same index from Settings → MCP Server.

Check what it found

Search runs the same query the agent would, and shows the file, the passage, and the score.

Search matches on keywords and on meaning together. Select a result to read the full passage.
Retrieval Lab runs your own questions against two search setups side by side, so a settings change is a measured choice.
Conflicts lists passages that are nearly identical and state different values, such as an old runbook and its replacement. You pick which one the agent should trust.

The license is one payment of $29 for three devices. It also unlocks the paid features of the Aura Terran desktop app for Windows, which ships at the same version.

To buy: get a key on the product page, then paste it into Settings → License. Cloud sources sign in with your own account, download to your computer, and are indexed there.

Where it runs

Platform	Status
Windows 10 and 11	Supported
macOS, Apple silicon and Intel	Preview
Linux, x64 and arm64	Preview. Needs OpenSSL (`libssl`), which most distributions include

On macOS and Linux the editor extension is the whole product. Reading scanned PDFs and images is Windows only for now. If something fails on a preview platform, tell us and include the Aura Terran output channel.

Frequently asked questions

Do my files get uploaded?
They stay on your computer. Indexing and search run there, and the index is a local database under ~/.aura-terran. The answer to a question is written by the chat model you already use, so the passages Terran returns go wherever that model runs.

What does it download?
The Terran server on first run, once per release, and a 23 MB embedding model the first time it indexes. Both are stored under ~/.aura-terran.

Do I need an API key?
No. Embeddings are computed on your computer. Your editor's chat asks Terran for passages and writes the answer with the model it already has.

Will this replace Copilot or Cursor?
Terran is the library those chats search. You keep the assistant you already have, and it gains your documents.

What happens if I never buy the license?
Everything in the Free column keeps working, including at work. Nothing is deleted and nothing expires.

Where does the $29 go?
Into continued development. It is one payment, with no subscription.
