Refine your AI mockup without losing the original
First render not quite right? Request up to 3 amendments per mockup. Change the colours, swap the materials, adjust the layout. The AI re-runs from your original photo so quality stays sharp through every iteration. Customer can flick between versions to see how each change looks.
The problem amendments solve
The first AI render is rarely the final answer. The customer wants the worktops a different colour, or the cabinets in a different finish, or asks "what would it look like with herringbone flooring instead of plank?". Without amendments, you're either quoting based on a render the customer doesn't love or running fresh renders manually each time.
Amendments let you iterate quickly. Type the change ("change worktops to white marble"), wait 30 seconds, show the customer the new version. Up to 3 times per mockup.
How amendments work
- Generate the initial mockup as normal (upload photo, type brief, run AI)
- On the result page, click Request an amendment
- Type your change as a short instruction
- The AI re-runs using your original photo plus the cumulative amendment text
- The new render appears alongside the original — switch between them in the gallery
- Repeat up to 2 more times if needed
Why we use the original photo, not the last render
This is a deliberate engineering choice that's easy to get wrong.
The naive approach is "previous render + amendment text" — feed the latest render back to the AI and ask it to make a small tweak. This sounds clean but in practice it degrades quality fast: chained image-edits through gpt-image-1 tend to drift, lose detail, mess up colours, and produce muddier output with every iteration. By the third amendment, the result looks visibly worse than the first render.
The correct approach is "original photo + cumulative amendment text". Every amendment uses the same original room photo (sharp, undegraded) plus a single combined prompt that includes your original brief and all amendments so far. The AI has full context, no chained-edit drift, and the third amendment looks just as sharp as the first.
Examples of good amendments
- Change the worktops to white quartz instead of black granite.
- Make the cabinets dark navy instead of grey.
- Add a kitchen island with seating for 4.
- Use a herringbone tile pattern on the floor.
- Swap the brushed nickel taps for matte black.
- Change the wall colour to sage green.
What you see in the customer modal
On the saved-mockup view (Saved Mockups → click any mockup), the modal shows:
- The original room photo (top-left)
- The initial AI render (top-right)
- A "Design Evolution" strip below showing thumbnails of every amendment
- Click any thumbnail to swap the main After image and see that amendment's brief caption
- Download as PDF — multi-page including the original photo, initial render, and every amendment with captions
What gets included in the PDF
When you download a mockup with amendments as a PDF:
- Page 1 — Original photo (no caption)
- Page 2 — Initial render (caption = original brief)
- Page 3 — Amendment 1 render (caption = amendment 1 text)
- Page 4 — Amendment 2 render (caption = amendment 2 text)
- Page 5 — Amendment 3 render (caption = amendment 3 text)
Every page respects your letterhead margins. Captions render as 10pt black bold text under each image. The PDF is a complete record of the design conversation.
