A fan-made web application inspired by the MAGI supercomputer from Neon Genesis Evangelion. Enter a yes/no question and watch three AI units deliberate simultaneously, then reach a verdict by majority vote.
| Unit | AI Model | Perspective |
|---|---|---|
| MELCHIOR • 1 | OpenAI GPT | Scientist — logic and rational analysis |
| BALTHASAR • 2 | Anthropic Claude | Mother — protection and care-oriented |
| CASPER • 3 | Google Gemini | Woman — intuition and emotional insight |
| Result | Meaning |
|---|---|
| 承認（APPROVE） | Majority voted yes |
| 否決（REJECT） | Majority voted no |
| 棄権（ABSTAIN） | At least two units abstained |
| 膠着（DEADLOCK） | No majority reached |
Critical Matter: If two or more units assess the topic as irreversible and potentially catastrophic (e.g. self-destruction, killing), the system automatically switches to a unanimous rule — all three units must approve for the action to proceed; any dissent or abstention results in rejection. Click any unit to see whether it flagged the topic as critical.
You will need API keys for the following services:
- OpenAI — for MELCHIOR-1
- Anthropic — for BALTHASAR-2
- Google AI Studio — for CASPER-3
