1. Getting Started

Creating Your Account

To get started with Cras AI, you need to create a free account. When you sign up, you'll automatically receive:

  • 2,000 free tokens - Start using AI immediately
  • 5 PDF pages - Upload and analyze PDF documents

Your First Query

Once logged in, simply type your question in the search box and press Enter. Cras AI will analyze your query and provide an intelligent response using the most suitable AI model.

2. Understanding Tokens

What Are Tokens?

Tokens are the currency used in Cras AI. Every interaction with AI models consumes tokens based on:

  • The length of your prompt (input)
  • The length of the AI's response (output)
  • The model you're using (different models have different token multipliers)

Token Calculation

Approximately 1 token ≈ 4 characters. The system applies a 2.2x multiplier to ensure accurate usage tracking. More advanced models like GPT-5 or Claude 4.5 consume more tokens per interaction.

Checking Your Token Balance

You can check your remaining tokens at any time by clicking on the "Usage" button in the navigation menu. This will show you:

  • Total tokens used
  • Remaining tokens
  • PDF pages remaining

3. Purchasing Token Codes

Where to Buy

You can purchase Cras AI token codes from our official partner:

Visit the link above to purchase token codes. Available packages include various token amounts to suit your needs.

Available Packages

Token codes are available in different packages, from small top-ups to large bundles. Each code comes with:

  • A unique code
  • An optional CVC (for security)
  • The token amount clearly stated

4. Activating Token Codes

Step-by-Step Guide

  1. Navigate to Usage Page

    Click on the "Usage" button in the navigation menu (or go to Settings → Usage).

  2. Enter Your Code

    Find the "Redeem Token Code" section and enter your token code in the input field.

  3. Enter CVC (if required)

    If your code has a CVC, you'll be prompted to enter it. Some codes don't require a CVC - you can leave it empty in that case.

  4. Click "Add" or "Redeem"

    Click the button to activate your code. You'll see a confirmation message and your token balance will update immediately.

💡 Tip: If you encounter any issues, make sure you're entering the code exactly as provided, including any capital letters. Codes are case-insensitive but must match exactly.

5. AI Models & Selection

Available Models

Cras AI supports multiple state-of-the-art AI models:

OpenAI Models

6. Automatic Model Selection

🤖 How It Works

Automatic Model Selection is Cras AI's intelligent feature that analyzes your query and automatically chooses the best AI model for your specific task. This ensures optimal performance and cost-efficiency.

The system uses advanced AI (DeepSeek) to analyze your prompt and determine which model would provide the best answer based on:

  • The complexity of your question
  • The type of information needed
  • The required response quality
  • Cost optimization

How to Enable

  1. Go to the chat or index page
  2. Look for the model selection dropdown (usually in the top navigation)
  3. Select "🤖 Automatic" or "Automatic Model Selection"
  4. That's it! The system will now automatically choose the best model for each query

✨ Benefits: Automatic selection saves you time, ensures optimal results, and helps manage your token usage efficiently by choosing the most cost-effective model for each task.

7. Manual Model Selection

When to Use Manual Selection

Sometimes you may want to use a specific model for your task. Manual selection is perfect when:

  • You have a preference for a specific model
  • You're testing different models for comparison
  • You need a model with specific capabilities (e.g., image processing)
  • You want to use a faster or more cost-effective model

How to Select a Model Manually

  1. Find the Model Dropdown

    Look for the model selector in the navigation bar or chat interface

  2. Click to Open

    Click on the current model name to see all available options

  3. Choose Your Model

    Select from the list of available models organized by category (OpenAI, Anthropic, Google, etc.)

  4. Start Chatting

    Your selected model will be used for all subsequent queries until you change it
