# Getting started

> Guest mode, signing in, and linking a wallet, what each unlocks and where your data lives.

There are three ways to use LETHE, and they stack.

## 1. Guest (no signup)

Open [asklethe.ai](https://asklethe.ai) and start chatting immediately. You get 3 free messages per network. Chat and Studio history is saved to your browser's `localStorage` only. It's private to that device and browser, and clearing site data clears it.

## 2. Sign in for cross-device history

Create an account to sync chat and Studio history across devices. Supported sign-in methods:

* Email magic link
* Google OAuth
* Discord OAuth
* Ethereum wallet (Sign-In with Ethereum / SIWE)

Signed-in history moves to a Supabase-backed database scoped to your account.

## 3. Link a wallet for higher limits + API access

Independent of account sign-in, visit [`/cli`](https://asklethe.ai/cli) and connect a wallet to:

* Raise your daily limit to 50 messages/day (UTC) on this network
* Get a portable API key (`ltk_…`) usable from any machine, CLI, or SDK. See [API Quickstart](/api-reference/quickstart)

<Tip>
  Wallet linking and account sign-in are separate systems. You can link a wallet for quota without creating an account, and vice versa.
