The design platform that thinks while you draw.
Draw floor plans. Run compliance. Analyse structure, solar, and MEP. Chat with your project in plain English. Manage the full RIBA lifecycle without leaving your browser. Purple8 Architect is the AI-native design platform for architecture firms — powered by Purple8.

What's inside
Every surface an architect needs. One platform.
AI Chat
Ask anything about your project
Conversational AI grounded in your entire project knowledge base — drawings, specs, RFIs, contracts, BIM models, and code compliance. The chat agent auto-dispatches to 14 AEC tools and routes results back into your project graph. Every answer cites its source.
- Every answer is grounded in your actual project documents — drawings, specs, contracts, BIM models
- Understands your whole project — asks about Level 3 structural issues and gets a real answer, not a generic one
- Covers compliance, cost, structural, MEP, solar, spatial design, and cultural design guidance
- Cites the exact document, page, and clause behind every response — no hallucinations
- Chat automatically pre-fills your project brief — one click saves it to the project lifecycle
Canvas
Precision floor plan design with AI overlays
Vector drawing surface built for architects — not a whiteboard tool. GEA/GIA/NLA area layers to RICS standard, multi-user live cursors, 3D view with door and window openings, and AI-generated massing and layout suggestions. Runs in the browser. Works on iPad.
- Draw polygon rooms with arc walls, symbols (door, window, stair, lift), and dimension annotations
- GEA / GIA / NLA area layers with live schedule — RICS-standard from day one
- Space Syntax (VGA) · Structural span warnings · Wellbeing score overlays
- 3D view — extruded rooms, wall geometry, door/window openings via Three.js
- AI massing generator — 3 strategies (Compact Bar, Linear Slab, Split Wings)
- AI layout suggestions — Vastu · Intelligent Grid · Compact Cluster, applied one-click
- Solar overlay with live GPS and device compass for true-north sun paths
- Multi-user shape sync and live cursors — no WebSocket server required
- Export: PDF · SVG · DXF (AutoCAD) · CSV area schedule
Sketch
Freehand design with Apple Pencil intelligence
A freehand drawing board built for early-stage ideation. Pressure, tilt, and coalesced events for Apple Pencil. AI interprets your sketch and generates photorealistic renders. Sketches hand off directly to the project journey.
- Apple Pencil with pressure, tilt, and coalesced events — fine, bold, and pencil brush styles
- 8 layers with per-layer undo, mirror symmetry, import underlay for tracing
- AI Interpret — describes rooms, spatial reads, and design intent from your sketch
- "Send to Project →" attaches sketch to the active project stage in Journey
Projects (Journey)
Full RIBA lifecycle. Zero spreadsheets.
14 RIBA-mapped project stages from brief to handover, managed by the Purple8 Journey Engine. Stage approvals, SLA monitoring, scenario branching, and a full immutable audit trail — all stored in the project knowledge graph.
- 14 RIBA-mapped stages from concept brief to post-occupancy evaluation
- Human-in-the-loop approval gates — stage advance restricted to principal architect role
- Scenario branching — up to 5 named snapshots per project
- SLA monitoring — know which deliverables are at risk before they slip
- Full immutable audit trail: every design decision, tool run, and stage transition
- Pre-filled from Chat draft — no re-entering what the AI already knows
Algorithms
12 Phase 8 design algorithms. All running on the graph.
Structural, MEP, spatial, and generative analysis built directly into the graph engine — no export, no third-party solver. Results feed back into the knowledge base so every AI response can reason over them. Chat routes directly to the relevant algorithm tab.
- Space Syntax & VGA — visibility graph, integration scoring, axial maps
- Structural topology — rigidity, load path tracing, critical member detection
- MEP max-flow / min-cut — fault isolation, energy balance, thermal zone simulation
- Spectral optimisation — Fiedler value, robustness index, natural frequency estimation
- Generative design — constraint propagation, Pareto-optimised spatial layouts
- IFC / BIM — ingestion, clash detection, change propagation, delta sync, rewriting
- Chat → Algorithm routing: AI responses link directly to the relevant algorithm tab
GIS & Site
Site intelligence before you draw the first line
Solar path, space syntax, wind, flood, ecology, and urban context analysis — all available before you open Canvas. Grounded in live regulatory and market data via the Knowledge Hydrator.
- Solar analysis — summer / equinox / winter sun paths with latitude-accurate angles
- Flood, seismic, and climate context from verified sources
- Space syntax and urban context — connectivity and integration scoring
- Knowledge Hydrator — building codes and market prices continuously updated from official sources
Consolidation
One platform. Not seven subscriptions.
Architecture firms typically juggle separate tools for drawing, project management, model coordination, and AI chat. Architect brings them together in one knowledge graph.
Autodesk Construction Cloud
project workflows + document management
Procore
project management + RFI tracking
BIM 360
model coordination + clash detection
SketchUp / Rhino
concept massing + 3D modelling
Bluebeam
drawing markup + review
PowerBI / Tableau
project analytics
Separate AI chat tools
