| Tagline | Run any open-source AI model with an API call. | The playful, accessible AI video tool. | OpenAI's browser agent. Clicks and types on websites for you. | Anthropic's CLI agent. Opus-powered, operates on your repo directly. |

| Pricing | Pay per second of compute | Free + $8-$58/mo | Included with ChatGPT Pro $200/mo | Part of Claude Pro/Max/Team plans |
| Best for | Developers using open-source models (Flux, SDXL, Whisper, etc). | Social media creators, beginners, anyone wanting quick fun clips. | Power users willing to pay $200/mo for a browser bot. | Developers who want an agent, not autocomplete. Large refactors, tests, docs. |

| Kai's verdict | S-tier for open-source model APIs. The default in this space. | A-tier for social/casual. B-tier for serious work. Good entry point. | B-tier. Still early. Manus is more flexible for less money. | S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement. |
