Create an EidoStack Account

Create your EidoStack account and prepare your workspace to work with AI models from different providers.

Your account gives you access to a single workspace where your chats, settings, and experiment history are saved.

After registering, you'll need to complete the initial setup and connect at least one AI provider using your own API key. Registration alone does not automatically connect any models.

Before You Begin

Choose the sign-up method that works best for you:

• Email and password — register directly with EidoStack.
• Google — register using your existing Google account.
• GitHub — register using your existing GitHub account.

Registration with Google or GitHub requires a verified email address.

You don't need an API key to create an account. You'll add one later, during workspace setup.

Important: Google and GitHub on the registration page are used only to sign in to EidoStack. Signing in with Google does not connect Google AI models, and registering with GitHub does not provide access to AI models.

To work with AI models, EidoStack uses the Bring Your Own Key (BYOK) approach. You connect your own OpenAI, Anthropic, or Google AI API keys and manage the costs of using their APIs yourself.

Create an Account with Email and Password

1. Open EidoStack and go to the sign-in page.
2. Under Don't have an account?, select Create one.

3. On the Create account page, fill in the following fields:
   • Full name — enter your full name.
   • Email — enter the email address you want to use to sign in.

4. Enter a password in Password. It must be at least eight characters long. A password-strength indicator appears as you type.
5. Select Create account.

If your information is valid, EidoStack creates your account and displays a confirmation page.

Select Continue to sign in, then sign in using the email address and password you entered during registration.

After you sign in, EidoStack automatically opens the initial setup dialog to help you prepare the Playground for working with AI models.

Create an Account with Google or GitHub

You can register with EidoStack using Google or GitHub without creating a separate password.

1. Open the Create account page.
2. Select Continue with Google or Continue with GitHub.

3. Choose the account you want to use and complete the authorization process with Google or GitHub.
4. After authorization succeeds, you'll return to EidoStack.

If the selected provider supplies a verified email address that is not already associated with an EidoStack account, EidoStack creates a new account and displays a confirmation page.

Select Continue to sign in, then choose Google or GitHub again and sign in with the same account you used to register.

The initial Playground setup opens after you sign in.

If that email address is already associated with an EidoStack account, use your existing sign-in method instead of registering again.

For more information about authentication and account recovery, see Sign in and recover access.

Set Up Your AI Playground

After your first sign-in, you'll see the Welcome to EidoStack dialog.

The setup wizard guides you through four steps to prepare your workspace.

During setup, you can:

1. Optionally set a global system prompt with general instructions for AI models.
2. Create or unlock a local encrypted API key vault.
3. Add your own OpenAI, Anthropic, or Google AI API key.
4. Complete setup and open your Playground workspace.

You need to add at least one provider API key to move past the model-connection step.

On the final step, select Start Using EidoStack to save your settings and open the workspace.

If you close the dialog or select Skip, you can return to setup later. Selecting Don't show this dialog again completes onboarding without displaying the wizard again.

For a detailed walkthrough of each step, see Complete workspace setup.

What You Can Do After Setup

After connecting an AI provider, you can use EidoStack as a regular AI chat or as a Playground for experimenting with models.

For example, you can:

• Chat with AI models. Ask questions, generate and review code, solve technical problems, and continue conversations.
• Explore model capabilities. Try different models and see how they handle the same tasks.
• Experiment with prompts. Change instructions and system prompts to see how they affect responses.
• Compare results. Send the same requests to multiple models and examine the differences between their responses.
• Analyze API usage. Track token counts, context-window usage, and estimated request costs.
• Save your work history. Organize chats into folders and return to previous experiments.

Available features and input types depend on the selected model and what the Playground currently supports.

No additional software installation is required to get started — the Playground works directly in your browser.

If You Cannot Create an Account

If you encounter an error during registration, check the information you entered first.

When registering with email and password, make sure that:

• Your name is not empty.
• Your email address is in a valid format.
• Your password contains at least eight characters.

If EidoStack cannot connect to the service, check your internet connection and try again.

When using Google or GitHub, make sure you've selected the intended account and that its email address is verified.

If EidoStack reports that an account already exists, try signing in instead of registering again.

If you've forgotten your password, follow the instructions in Sign in and recover access.

Next Steps

After creating your account, complete the initial setup and prepare your Playground for its first request.

1. Complete workspace setup — configure the essentials and set up your local API key vault.
2. Configure your first AI provider — add your own OpenAI, Anthropic, or Google AI API key.
3. Start your first chat — select a model and send your first request.

After that, you can switch between supported models, experiment with prompts, compare responses, and explore AI capabilities in one workspace.
