Ratatouille is developing AI creative software for architects: compare alternatives, work with editable models, and use critique to decide what changes.

Study 001 / A neighbourhood reading room
Quiet reading. Small gatherings.
Illustrative study — not product output
Share the centre
Reading rooms and a meeting room face one courtyard. Arrival and gathering share the same route.
Trade-offA clear common centre; quiet readers pass through the shared activity.

The problem
An image can suggest.
A proposal has to answer.
Where do people enter? What stays quiet? What gets shared? Architectural ideas need decisions you can inspect and change.
We’re exploring how AI collaborators can help carry those decisions through editable work and meaningful revision—with your judgment shaping the direction.

Quiet reading.
Room to gather.
A neighbourhood reading room.
An original illustrative study.
The brief
Give individual readers a quiet place, and a small group somewhere to meet. Let them share a centre without forcing every arrival through the same activity.
Reading / Meeting / Arrival01 / First arrangementGather — original
A common centre
Rooms face one courtyard. The meeting room and reading rooms share the arrival sequence.
02 / An authored revisionChanged zones in vermilion
A different way in
The west wing splits around a side passage. Arrival can bypass the meeting room; two smaller reading rooms replace one larger room.
The question that changes the workCompare it in Model / Plan
Could a reader arrive without crossing the meeting room?
The revision changes access, rather than dressing up the first scheme. It also gives up reading space. That trade-off stays visible.
Compare
Three responses to the same brief.
Develop
One spatial definition across plan and model.
Question & revise
A specific decision, with a visible consequence.
Illustrative study — not product output. These are authored schematic drawings, not AI-generated architecture or a construction-ready proposal.

A connected creative process
Bring the pieces together around a shared proposal: alternatives, editable work, criticism, and a considered next version.
That end-to-end public application has not launched. The illustrative study above explains the intention; it does not demonstrate the software.

answers.
Can I use Ratatouille today?
Public product access has not launched. The founder is the first user of the prototype components. You can join for occasional project updates; joining does not create an account or reserve access.
Who is it for?
The first focus is individual architects developing concept proposals—people comparing spatial possibilities, developing editable work, and deciding what should change.
Is this study AI-generated?
No. The reading-room study is an authored illustration of a design process. Its alternatives, critiques, and revisions were written and drawn for this website. It is not product output.
What exists, and what is still planned?
Separate experiments explore native model editing, drawing projections, rendering, and recorded critique. Connecting those components into a coherent end-to-end public application is ongoing work.
