A few answers before you start
Find the basics of designing with ChatHome.ai, choosing a plan, and keeping your work.
Getting started
What is ChatHome.ai?
ChatHome.ai is a browser-based home design studio. Describe a home to generate an editable 3D concept, refine a generated plan through chat, or use the tools to draw and edit by hand.
Do I need design experience?
You can begin by describing the rooms and features you want. The getting-started guides explain the main steps and tools as you develop the concept.
Do I need an account?
You can use the manual editor, Explore mode, and live-scene exports without one. AI generation, cloud designs, and sharing controls require an account. You can also set an optional account region for the quantities report's material conventions.
Do I need to install an app?
The studio runs in your web browser. The walkthrough instructions use keyboard and pointer controls; start there when learning to move around.
Can I work in feet and inches?
Yes. Choose ft beside Edit and Explore to read and enter feet and inches; choose m for metres. Switching leaves the home unchanged. The PDF follows your choice, while model files and some reports remain metric. See the units guide.
Creating with AI
What should I include in a brief?
Start with plot dimensions, the entrance side, rooms, and floors. Add exact room dimensions when essential, then a few preferences for finishes or outdoor space. See a complete example.
Can I upload a floor-plan image?
Image, PDF, and DWG floor-plan recognition are not available. You can describe a home, draw a layout using known measurements, or import a ChatHome.ai JSON design file.
Will every detail in my brief be included?
Some requests depend on available space. The result notes explain changed sizes, substitutions, and missing items. Stated room dimensions describe inside space; check the delivered measurements and notes. Learn how to read your design results.
Can I change the design through chat?
Yes. Send a revision request for a generated plan and review What changed. A revision can rearrange other parts of the layout and may replace manual edits. Save an alternative before changing direction.
Will a revision change the size of my house?
A revision keeps the house outline unless you ask to resize it; rooms you add share the existing space. Ask directly to resize the house, and check What changed for any outline adjustment. A change that cannot fit is declined with the reason: a result marked “declined — plan unchanged” keeps your plan as it was and uses no generation. Learn how revisions and resizing work.
What is the difference between Ask and a revision?
Ask explains the generated plan without changing the scene. A revision creates an updated result and uses a generation if successful. Ask may not reflect later hand edits to the scene.
Why can I not see Generate?
The control appears after you sign in when generation is enabled for the service. The manual studio remains available if generation is unavailable.
Plans and usage
Is there a free plan?
Yes. Payments are currently off, and every account has Pro limits: unlimited cloud designs and 200 successful generations per rolling 24 hours. Explorer, Home Pass, Pro, and Studio appear in the planned USD pricing table; paid packages are not yet available to purchase.
Do questions or failed attempts use my allowance?
No. Successful AI generations and revisions count. Failed attempts, Ask questions, and manual edits do not. Daily usage is measured over a rolling 24 hours. See a worked example of generation usage.
Can I use the reports during free access?
Yes. You can open the preliminary structure report and bill of quantities without spending a generation. The first follows preliminary gravity loads; the second provides indicative quantities, not a cost estimate.
Saving and sharing
Where is my work saved?
The current scene saves in your browser. Sign in and save it as a named cloud design to keep it in your account. Export JSON for a separate editable backup. Follow the saving guide.
What does “changed elsewhere” mean?
Your latest save replaced a newer save from another tab or device. Pause edits and agree which copy to keep; the notice does not merge changes or provide version recovery. Read the saving guide.
Can I restore any earlier version?
There is no automatic version history. Solo editor undo works within the current session, and Undo this turn can restore an earlier generated result when available. Keep separate saved copies for alternatives you want to retain. Keep and compare separate design alternatives.
Does someone need an account to view my design?
No, if you give them a public read-only share link. Anyone with the link can explore the latest saved scene. Current links display the Made with ChatHome.ai badge.
Can someone help me edit?
Yes. Add an existing account holder as an editor on your cloud design. The project appears under Shared with me in their account; no invitation email is sent. Choose and manage the right access.
What happens if we edit the same object together?
The later change takes effect and a notice explains the conflict. Undo is disabled during live collaboration. Read about working together.
Downloads and next steps
Which files can I download?
Current free access includes PNG images at screen size or higher resolution, dimensioned PDF plans, JSON, GLB, DXF, IFC, the preliminary structure report, and quantities downloads. Compare the formats and their contents.
Does the PDF include room dimensions?
Yes. It provides one dimensioned A3 page per storey, with openings, a scale bar, and a north arrow. Choose m or ft before exporting to get measurements in metres or feet and inches. It is a preliminary plan sheet, not a construction document. Read the PDF guide.
Can I see which quantities changed?
A generated revision can have a quantities change log against its parent under the same regional practice. It uses stored generated results and excludes later hand edits. Read the quantities comparison guide.
Can I build directly from the generated design?
Use it to develop and communicate a concept. It does not provide construction-ready drawings, building services, or a structural approval. Have qualified professionals develop and check the project before construction.
