ARK Design AI
Ark Design AI automates floor plan generation and feasibility studies for multi-family and mixed-use development. It optimises unit mix for density, profitability and living standards, checks against local building code and ordinances for US projects, and produces area tables and feasibility reports. It holds a US patent.
- Automates the stage of development work that is most often discarded, which is exactly the right target
- Testing twelve configurations instead of one is how a viable scheme actually gets found
- Automatic area schedules remove both manual arithmetic and drift between drawing and financial model
- Code checking catches the constraint problems that otherwise surface expensively late
- Automated code checking is a first pass, not a determination, and the site does not draw that line firmly
- US-only code coverage, with the specific jurisdictions not enumerated anywhere we could read
- Code data update frequency is not stated, which matters because ordinances change
Decory
Decory is a free mobile AI interior design app that redesigns a room from a photo in about 30 seconds across 15+ styles. It also replaces and removes objects, previews flooring and wall colours, and searches furniture. Operated by The AI Journey Inc., with 500,000+ downloads claimed.
- Fast enough to change behaviour — thirty seconds means you actually iterate
- Comparative viewing reveals your taste better than any description
- Object-level tools answer decisions with a purchase attached
- Object removal is a quick way to test whether something was the problem
- Generated rooms take liberties with geometry, so nothing is buildable from them
- No dimensions, so a piece that looks right may not fit
- Lighting is rendered to look good rather than to match your room's aspect
