| Kai's verdict | S-tier for conversation. A-tier for TTS. Complement to ElevenLabs, not replacement. | S-tier in its category. The first AI music tool I'd actually listen to. | B-tier. Still early. Manus is more flexible for less money. | S-tier for text-in-image. Use this for posters, Midjourney for art. |
