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

​
1. Guest (no signup)

Open 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. Independent of account sign-in, visit /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
Wallet linking and account sign-in are separate systems. You can link a wallet for quota without creating an account, and vice versa.
