Finch 3D

Finch 3D sits in a specific gap: too many options for a hand-drawn schematic pass, not enough authoring depth for construction documentation. That is deliberate. The product assumes you are testing feasibility and unit mix, not producing permit sets. Where it is strong. The encode-once approach is the core idea and it shows up across the product. You configure your firm's systems and institutional knowledge, and generation runs against those rules plus local codes, so early iterations are already roughly buildable rather than throwaway massing. Real-time building performance metrics update as you change parameters, which means trade-off exploration happens in the same session rather than in a separate analysis pass. The four typologies — master plan, residential, high-rise, office test fit — each get purpose-built behaviour, notably automatic vertical alignment for high-rise layouts, which is the kind of thing that is tedious to maintain by hand across a large project. Where it is limited. This is not a full BIM authoring suite; the seed data is explicit that construction documentation is out of scope, and the geometry tops out around LOD 300. Freeform organic modelling is not the target either, so if your work is formally driven rather than unit-and-code driven, look elsewhere. There is also a real floor on who benefits: beginners without AEC or generative design experience will struggle, and so will teams whose projects need custom parametric scripting beyond the preset rules. The vendor names no underlying AI models anywhere in the scraped content, so we cannot tell you which models power generation. Where it fits. Mid-to-large practices already running Revit or Rhino are the natural home — the documented integrations (Revit, IFC, BIM 360, Grasshopper, Rhino) mean output flows into existing BIM pipelines rather than requiring a parallel toolchain. Master planning teams doing density and unit-mix analysis get the most obvious speed gain. Office space planners generating test fits from a brief and checking them against compliance codes get a workflow that is hard to replicate with generic tools. Pricing reality. The Free tier is genuinely usable for a single user with all editing tools and real-time performance metrics. Basic at €79 billed monthly adds optimized unit mix and circulation generation on a 14-day free trial, but stays single-user. Enterprise at €14,500 billed annually for 3 seats is where the firm-wide features live — plan library, code and compliance check, custom BIM export, the AI agent, and SSO. A five-person practice is looking at over €20,000 a year once you cover seats, which is the number to test against the hours you would otherwise spend on schematic iterations.
