Nano Banana hallucinates.MONA delivers your project.
Nano Banana is a serious image model, and one-off generations can look terrific. Then you ask for one change. The sofa you loved gets redrawn, a lamp you never asked for appears, and the room shifts under your feet on every pass. MONA is built for revision-safe design work: it changes exactly what you name, keeps everything else pixel-still, and never invents furniture your client did not approve.
Pick the tool that fits the job.
Choose Nano Banana for
One-off images and edits
Quick generations, retouches, and visual experiments where the image itself is the whole job.
Social and content visuals
Eye-catching imagery where fidelity to a specific real space is not the point.
You enjoy prompt craft
Hand-tuning prompts and iterating manually to chase a specific look, frame by frame.
Choose MONA for
Renders of the actual space
The output has to match the floorplan the contractor is building from.
Edits that hold still
Swap the sofa and the sofa swaps. The rug, the light, and the wall the client approved do not move.
What happens after the image
Products, budgets, purchase orders, decks, and the client conversation, in the same system.
Nano Banana and MONA, capability by capability.
Where MONA wins.
01
A system, not a model
Models make images. MONA makes projects: the model is one component inside a workflow that knows your plan, your palette, and your client.
02
Plan-faithful geometry
MONA starts from the drawing set, so the render shows the room that will actually be built, at the angles that sell it.
03
Edits that behave
Image models repaint the whole scene to change one thing, and every pass is a fresh roll of the dice. MONA makes the edit you asked for and treats the rest of the room as untouchable.
04
Nothing you did not ask for
No phantom lamps, no invented windows, no third throw pillow the client never approved. MONA renders from your plan, your palette, and your product list, so what appears is what was chosen.
05
The scheme holds
Approved materials and palette carry across every render and revision automatically, without re-prompting the look each time.
06
Objects you can buy
MONA matches rendered pieces to real, purchasable products with specs and trade pricing, so the concept survives contact with the budget.
Frequently asked questions.
Is Nano Banana good for interior design?+
For single images and edits, genuinely good. The gap appears the moment a client is involved: edits redraw things they already approved, objects appear that nobody chose, and the scheme drifts between rooms and revisions. MONA is built so the approved image stays approved.
Why does the image keep changing when I only asked for one edit?+
Because image models regenerate the scene to apply a change, everything in frame is up for renegotiation on every pass, and they will happily add furniture you never mentioned. MONA works differently: edits are targeted, the rest of the room is held fixed, and objects come from your plan and product list rather than the model’s imagination.
What is the real difference between Nano Banana and MONA?+
Nano Banana is an image model you drive by hand. MONA is a studio operating system where generation is one capability among many: plan reading, style lock, sourcing, procurement, presentations, and project management.
Does MONA just use a model like Nano Banana under the hood?+
MONA orchestrates frontier generative models inside a pipeline built for design work: floorplan understanding in front, style and material locks around, and product matching, decks, and procurement behind.
Can I use both?+
Sure. Keep an image model for one-off visuals and experiments. When the work is a real project with a real plan and a real budget, run it through MONA.
How much does MONA cost?+
MONA plans start at $19 per month, with studio plans at $99, $199, and $399 per month. Every plan starts with a 7-day free trial, and there is a 30-day money-back guarantee.
