- Merlin vs Monica

Pricing comparison (buyer caution)
- Merlin’s ~$19/mo messaging competes with the typical $20/mo anchor for single-vendor premium plans, but the real value depends on:
  - How many “premium” model calls are actually included before throttling.
  - Whether the models are truly equivalent versions.
  - Whether browsing/citations are reliable.
Customer testimonials comparing to competitors
