Start from what you have and what you want, and find the Luw\.ai tool that fits. This page helps you pick a tool by starting from what you have in hand and what you want to end up with. Each line links to the tool's own page. {% hint style="info" %} The app has a short questionnaire that does the same job: open **Help** in the sidebar and click **Help me find the right tool**. See [Help and support](/luw.ai-app-docs/connect/help-and-support.md). {% endhint %} ## I have a photo of a room * **Give the room a new look:** [Interior AI](/luw.ai-app-docs/redesign-spaces/interior-ai.md). Pick the room type and up to three styles. * **Furnish an empty room:** [Interior AI](/luw.ai-app-docs/redesign-spaces/interior-ai.md) with **Fill Empty Room** switched on. * **Empty a furnished room:** [Remove Furniture](/luw.ai-app-docs/redesign-spaces/remove-furniture.md). * **See a mood board come to life in the room:** [Mood Board AI](/luw.ai-app-docs/redesign-spaces/mood-board-ai.md), in **See moodboard in Your Space** mode. * **Place specific furniture in the room:** [3DSpace AI](/luw.ai-app-docs/3d-and-video/3dspace-ai.md). Add furniture images or 3D models to a 3D version of your room, then render it. ## I have a photo of a building * **Restyle the outside:** [Exterior AI](/luw.ai-app-docs/redesign-spaces/exterior-ai.md). * **Show more of it than the photo caught:** [Expand](/luw.ai-app-docs/edit-images/expand-ai.md) extends a cropped photo beyond its edges. ## I have a photo of a garden or yard * **Plan a new garden:** [Landscape AI](/luw.ai-app-docs/redesign-spaces/landscape-ai.md). Select the area to plant, then choose a garden style, the sun exposure and your city. ## I have a photo of a product * **Put it in a new setting for marketing images:** [Change Background](/luw.ai-app-docs/edit-images/change-background.md). It can also remove the background. * **Turn it into a 3D model:** [3DGen AI](/luw.ai-app-docs/3d-and-video/3dgen-ai.md). You get a GLB file you can download or view in your own space. * **Get a clean line drawing for CAD:** [Vector AI](/luw.ai-app-docs/edit-images/vector-ai.md) makes an SVG. * **Make the picture bigger and sharper:** [Photo Enhancer](/luw.ai-app-docs/edit-images/photo-enhancer.md). ## I have a sketch, a 3D screenshot or a floor plan * **A sketch or drawing:** [Sketch](/luw.ai-app-docs/render-and-create/sketch-ai.md) turns it into a rendered image. * **A screenshot from a 3D program:** [Render AI](/luw.ai-app-docs/render-and-create/render-ai.md) makes it photorealistic and keeps the geometry. Set the time of day and the lighting. * **A floor plan you want to build on:** [Floor Planner AI](/luw.ai-app-docs/3d-and-video/floor-planner-ai.md) opens it in Luw\.ai Studio as an editable scene. * **A floor plan you just want to see in 3D:** [Interior AI](/luw.ai-app-docs/redesign-spaces/interior-ai.md) renders a floor plan as a 3D view of the plan. ## I have nothing yet * **Make a picture from a description:** [Fluw](/luw.ai-app-docs/render-and-create/fluw.md) turns words into photos or illustrations. * **Make a texture or pattern:** [Pattern AI](/luw.ai-app-docs/render-and-create/pattern-ai.md) makes tileable textures from a description. * **Create a starting photo for any tool:** click **Generate Image with AI** in the tool's upload area, describe the picture, and use the result as your photo. See [Generate an image to start from](/luw.ai-app-docs/working-with-images/generate-an-image.md). * **Get ideas first:** ask [ArchiGPT](/luw.ai-app-docs/assistant/archigpt.md), or browse what others have made in [Explore](/luw.ai-app-docs/organize-your-work/explore.md). ## I want to change one part of an image * **Change something by describing it:** [Magic Prompt AI](/luw.ai-app-docs/edit-images/magic-prompt-ai.md). For example, "add a plant next to the window". * **Replace, re-material or remove an exact area:** [Magic Wand AI](/luw.ai-app-docs/edit-images/magic-wand-ai.md). Select the area first, then describe the new fill, pick a material, or remove it. * **Change part of a design you've already made:** open the result and use **AI-Powered Magic Edit**. See [Edit and reuse a result](/luw.ai-app-docs/results/edit-and-reuse.md). * **Change only a product's surroundings:** [Change Background](/luw.ai-app-docs/edit-images/change-background.md). ## I want a video or a 3D model * **A short video of a design:** [Video AI](/luw.ai-app-docs/3d-and-video/video-ai.md) makes a clip of about 8 seconds with a camera move, in 1080p with sound. Add an end frame for a before → after clip. * **A 3D model of an object:** [3DGen AI](/luw.ai-app-docs/3d-and-video/3dgen-ai.md). * **A furnished room staged in 3D:** [3DSpace AI](/luw.ai-app-docs/3d-and-video/3dspace-ai.md). * **A whole building in 3D, to exact measurements:** [Luw.ai Studio](/luw.ai-app-docs/connect/luw-ai-studio.md). ## I want to ask a question * **Design and architecture questions:** [ArchiGPT](/luw.ai-app-docs/assistant/archigpt.md). It can also write a prompt for you from any prompt box. * **Questions about using Luw\.ai:** the **Help** page and the **Support** contact form. See [Help and support](/luw.ai-app-docs/connect/help-and-support.md). ## I want to run several tools in a row * [Workflows](/luw.ai-app-docs/workflows/workflows.md) chain tools on a canvas, so the result of one step feeds the next. You can also start from a workflow someone else has shared in **Explore Workflows**.
