Documentation
From raw to refined
Everything you need to forge your first vault with Obsidian — from account creation to document destruction.
Quick Start
Forging your first vault
Create an account
Sign up with your email address and password. No credit card is required to enter the forge.
Load the furnace
Navigate to Billing and top up your prepaid balance using Visa or Mastercard. Your balance fuels GPU compute time.
Forge a vault
Click "New Vault" from your dashboard. Give it a name, choose a use case preset and a model tier. A dedicated GPU instance usually provisions in a few minutes, occasionally up to 20; the typical spin-up time for each model tier is shown next to it in the form.
Mine and smelt
Drag and drop your documents into the vault. Chat with the AI to analyze, summarize, extract data, and generate reports. Documents are processed on your dedicated GPU; no third-party AI service sees them. With chat saving on (the default), your questions and replies are stored in our database.
Shatter when done
When you are finished, destroy the vault. Its GPU instance and disk, with your documents, are deleted. The glass shatters. This action is irreversible. The vault's saved chat history is deleted too.
Raw Materials
Accepted formats
Maximum file size: 50MB per document.
Analysis
The smelting process
Once your documents are loaded into the crucible, you interact with them through a natural language chat interface. The AI model running on your dedicated GPU processes your questions and generates responses based solely on the content of your uploaded documents.
Each vault comes with a use case preset that configures the system prompt for your specific workflow — legal review, financial analysis, medical records, HR compliance, due diligence, or general analysis. You can also provide a custom system prompt to temper the model to your exact needs.
The AI can summarize documents, extract specific data points, compare multiple documents, flag risks or issues, construct timelines, and generate structured reports. The model is instructed to cite the source document and page for what it tells you.
Viewing
Faceting the glass
Obsidian includes a built-in document viewer that allows you to review your uploaded documents alongside the AI chat. You can view PDFs, images, and text-based documents directly in the workspace.
Your documents stay exactly as you uploaded them: Obsidian reads, searches and cites them, but does not change them. They are deleted with the vault's instance when the vault is shattered.

Billing
The cost of forging
Obsidian uses a prepaid balance model with no subscriptions. Load your furnace with credit using Visa or Mastercard, then spend it on raw GPU compute.
GPU time is billed per minute at the hourly rate for your chosen model tier. Your balance is updated about once a minute as your vault runs. At zero balance you can't start or resume a vault, and a running vault is paused automatically when your balance can no longer cover the next minute, so your balance doesn't go below zero.
You can view your current balance, top-ups, and this month's usage from the Billing page in your dashboard. For more details, see our Pricing page.
