Everything else on the node can stay at defaults.\n\n## The two things that matter\n\n### 1. `image`\nConnect any image source (e.g. `Load Image`). That's the picture you want to pull something out of.\n\n### 2. `prompt`\nA short text description of **what to isolate**. The node segments whatever matches the prompt and removes the rest.\n\n## How to write the prompt\n\nKeep it **short, concrete, and noun-based**. You're naming a thing, not describing a scene.\n\n**Good prompts:**\n- `character`\n- `person`\n- `jacket`\n- `face`\n- `hair`\n- `car`\n- `dog`\n\n**Bad prompts:**\n- `the girl wearing a green bomber jacket standing against a wall` — too long, too descriptive\n- `cool anime vibes` — not an object\n- `remove background` — describes the action, not the subject\n\n## Rules of thumb\n\n- **One subject per prompt.** If you need two things, run the node twice or use a compound noun.\n- **Generic beats specific.** `character` works better than `anime girl with red hair`. Let the model find the obvious subject.\n- **Use the category, not the instance.** `jacket` rather than `green bomber jacket`.\n- **If it grabs the wrong thing**, try a broader word (`person` instead of `character`) or a more specific part (`face`, `torso`, `hands`).\n\n## Example\n\nWith the image on the left and prompt set to `character`, the node returns just the figure with the background cut away — which is exactly what the `Save Image` node outputs." ] } ], "revision": 0, "version": 0.4 }
