Complete workspace setup

After you create an account, EidoStack invites you to set up your workspace. This lets you connect AI models using your own API keys and start using the Playground to chat with models, experiment with prompts, compare responses, and analyze token usage and request costs.

To get started, you only need to create a secure API key vault and connect at least one AI provider. You can also set a global system prompt if you wish. The entire setup takes place in your browser.

What's included in the initial setup

The setup wizard has four steps: Welcome to EidoStack, Set a System Prompt, Connect Providers, and Ready to Explore. These are the step names displayed in the application.

During setup, you can:

• Set default instructions for new chats (optional).
• Create a local, encrypted API key vault.
• Add an API key for OpenAI, Anthropic, or Google AI.
• Open the Playground and choose a model for your first request.

Before you begin, have an API key from at least one supported provider ready. EidoStack does not issue API keys or include a subscription to AI models: API usage is billed directly by the respective provider. Learn more in Supported providers and models.

Set a global system prompt (optional)

On the Set a System Prompt step, you can fill in the Global System Prompt field. These instructions will be used as the initial system prompt in new chats.

For example, you can ask a model to respond in a particular language, follow a specific format, or meet certain style and content requirements. This is useful if you regularly use different models for similar tasks and want to give them the same starting instructions.

This field is optional. If you leave it blank, you can still use the Playground normally. You can also set a separate system prompt for an individual chat later.

The global setting applies to new chats and does not modify existing ones. You can change it under Settings > System Prompt. Learn more in System prompts.

Create and unlock your API key vault

On the Connect Providers step, first create a secure vault. EidoStack uses it to store your provider API keys in encrypted form in your browser.

1. In Create Master Password, enter a master password of at least eight characters that meets the displayed strength requirements.

2. Enter the same master password in Confirm Password.
3. If needed, enable Remember me on this device to keep the vault available in this browser on this device. Leave this option off on a shared computer.
4. Select Create & Unlock.

The master password protects the encrypted API keys stored for your account in this browser. EidoStack cannot recover a forgotten vault master password. Save it in a trusted password manager and, after adding your keys, back up your vault if you want a way to restore access.

Important: Your vault master password and your EidoStack account sign-in password are separate. Resetting your account password will not unlock or recover your API key vault.

Connect an AI provider

After you unlock the vault, the Connect Providers step shows fields for OpenAI, Anthropic, and Google AI.

1. Paste a valid API key for at least one provider.

2. If you need to check the entered value, use the key visibility control and then hide it again.
3. Continue when EidoStack detects that at least one key has been added.
4. On the final Ready to Explore step, select Start Using EidoStack to save your settings and open the workspace.

EidoStack follows the Bring Your Own Key (BYOK) approach: you connect your own API keys and pay for requests according to the selected AI provider's pricing. Keys are stored encrypted in your browser's local storage and used when making requests to models from the corresponding provider.

You do not need to connect all three providers. The Free plan lets you configure one provider, while Pro allows multiple providers. For instructions on adding, replacing, and checking keys, see Configure your first AI provider.

If you don't finish setup

You can close the setup wizard and return to it later. If you do not select Don't show this dialog again, the dialog may reappear when you open the workspace.

Selecting Don't show this dialog again stops the wizard from appearing again, but it does not create a vault or add API keys. You can complete those steps later under Settings > Providers.

If the vault is locked, the chat workspace displays an unlock form. If the selected model does not have a matching API key, EidoStack displays Open Provider Settings so you can configure the provider.

Check that your Playground is ready

Before sending your first request, make sure that:

• The vault shows Vault Unlocked.
• An API key for at least one provider has been saved in the browser.
• A model from a connected provider is enabled in the model selector.
• You can send a request without seeing a warning about a locked vault or missing API key.

Now you can start your first chat: choose a model, enter a prompt, and explore its response. Then try changing the system instruction, switching to another available model, or enabling response comparison. The Playground lets you do more than chat with AI models: you can also explore how their results, token consumption, and estimated request costs differ.

Once you've confirmed that the connection works, we recommend backing up your vault, especially if you plan to switch browsers or devices.
