WHY IT EXISTS

Why This Tool Exists

The Problem

Interior designers and architects who produce floor plans, elevations, and presentation documents daily are often locked into desktop CAD tools (AutoCAD, Vectorworks) that require local installation and licenses, and make real-time collaboration with teammates or clients across locations difficult.

The Solution

Browser-based drafting tool combining CAD drawing commands with lightweight BIM object behavior, requiring no installation and supporting real-time multiplayer editing, comments, and version history, plus an AI panel (semantic asset search, image-to-vector tracing, AI-generated visualizations) layered into the core drawing workflow.

TRANSPARENCY

Data Transparency

Exactly what this tool uses and how

Input

What it needs

Required: Design intent (walls, rooms, floor plan geometry)

Optional: Existing DWG/DXF files, PDF reference plans, Images for AI tracing, Laser-scan DXF exports (e.g., from iMapper)

Formats: DWG, DXF, PDF, JPG/PNG (images)

Output

What you get

Format: Drawing sets (floor plans, elevations, sections) with presentation documents

Fields: Floor plans, Elevations and sections, Mood boards, Schedules/tables (procurement, budgeting), AI-generated visualizations, Vectorized CAD tracings from images

Algorithm

How it works

Model: OpenAI embeddings (for semantic asset search via Meilisearch) plus undisclosed generative image/vector models for AI visualization and tracing features

Accuracy: Not publicly specified — vendor documentation describes the AI feature set as "Beta" and "still being refined," with no accuracy or benchmark figures published

Privacy

How your data is protected

Retention: Contractual/account data retained for the duration of the contract plus the applicable statute of limitations; invoicing data retained 10 years (French Commercial Code); direct-marketing data retained 3 years after account deletion

Training: Not publicly specified (privacy policy does not address whether user models or uploaded assets are used to train the AI features)

Compliance: GDPR (French CNIL oversight), No SOC 2 or ISO certification publicly disclosed

API

Integration

Endpoint: Contact vendor for API access

Method: Not publicly documented
