Limitations
–TheIndividual plan ($8.74/mo / €7.49/mo) is capped at 300,000 characters and just 3 file translations per month, requiring a jump to Team ($28.74/mo) or Business ($57.49/mo) for heavy workloads.

–DeepL Write Pro requires an extra €6.99/user/month add-on for Individual and Team subscribers unless upgrading to the Business tier.
TestFit
Automate site plans and test development deals in hours, not weeks
Generative site planning
Map any parcel or draw custom boundaries, then generate a buildable plan with road layout, turning radii and topography handled so you avoid redesign later.
Parking Solver
Produce optimal surface and structured parking layouts, set custom stalls and drive aisles, and validate parking ratios without manual drafting.
Site Intelligence data
Overlay parcel, environmental and zoning data, model 3D terrain with cut-and-fill analysis, and check power and utilities infrastructure before design assumptions harden.
Live-linked pro forma
Connect financial models directly to your design, with live pro forma figures and import of your own Excel templates, to see whether a deal pencils.
Strengths & Pros
+Turns site feasibility from a multi-week exercise into an hours-long loop, enabling far more alternatives per budget
+Financials are validated against a real generated layout instead of a rough assumption
+Approved plans push straight into Revit, SketchUp, AutoCAD, Excel and PDF, so early work is not throwaway
+Comprehensive typology coverage, from multi-family and industrial to data centers and structured parking
+Covers the whole early deal chain — zoning and terrain data, massing, parking, takeoffs and pro forma — in one platform
Limitations
–Entry price for automated feasibility starts at $15,000/year, which puts full generative design out of reach for very small teams
–Site Intelligence data layers such as parcel, flood zone and zoning coverage vary by country
–Training and support are English-only and operate during U.S. business hours
–Generative design and detailed typology solutions are gated to the Site Solver tier upward
