• Normal end

  Connection Lost

  Shows when a 60-minute class ends — not an error, just a normal end.
• Version mismatch

  Incompatible client

  Your Minecraft version doesn't match the server.
• U-000

  U-000

  Happens when the same server address is added multiple times.
• Java missing

  Launch failed

  Minecraft Java Edition isn't installed.
• Account

  Which account do I log in with?

  Always use the parent account that owns the subscription. There are no separate child accounts.
  💡 Log in with the parent account on every device — yours and the kid's. We don't have child accounts, so don't try to make one for your child. If you see Error 23, double-check by opening alephlab.ai/app in your web browser to confirm your account exists and your subscription is active.

  Open alephlab.ai/app ↗
• Error 23

  Account or subscription not found

  You're logged in with an account that doesn't have a subscription.
• Multiple kids

  Using Aleph Kids with multiple children

  Each subscription belongs to one parent account.
• Timeout

  Operation timed out

  Unstable Wi-Fi — not a server issue.
• No session

  No active class right now

  No session started, or the server address is wrong.
• Robotic voice

  I hear a robotic voice with odd English pronunciation, not Annie

  This isn't Annie — it's Minecraft's own accessibility voice (Text-to-Speech on Bedrock, Narrator on Java) reading the UI and chat through the device's TTS engine. Annie's actual voice uses US English.
• Not on server

  Stuck on 'Connect to Minecraft'

  The Aleph Kids app shows only the 'Connect to Minecraft' message. This means Minecraft hasn't connected to the server address we gave you yet.
• No voice

  I can see Annie but can't hear her voice

  Annie shows up in Minecraft but you hear no voice at all.
