- Fully open source and self-hostable with no vendor lock-in or proprietary format
| - Structured AI testing unlike chatbots: fixed crowd of individual profiles for your audience, every one answers each version, results counted by code
- No subscription: one-time purchases that don't expire while account is open
- Free first test with 100 AI-simulated participants
- Results by audience group, not just aggregate numbers
- Complete transparency: every number labeled as simulated, methodology fully explained
