Real-time AI canvas — but if you're comparing it to AlertForge, you're probably building a stream alert. Here's how the two actually differ.

What each does

Different products, different jobs

AlertForge

  • Event triggers — follower, sub, donation, raid
  • Built-in viewer-tip flow (Stripe Connect)

Krea
