Davis AI vs PLAN0

Two early-stage tools for developers and investors that answer different questions about a site or design. Davis AI is a Paris-based AI-assisted architecture firm that delivers feasibility studies and architectural designs as a service, with its own architects validating each stage. PLAN0 is construction cost intelligence software: upload architectural drawings and it parses the sheets, runs takeoff, builds a 3D model and returns a cost estimate. Desk research from vendor pages read Oct 27, 2026; not tested, no winner.

What it doesParis-based AI-assisted architecture firm that says it delivers feasibility studies and architectural designs in days, not months. It pairs AI with architect judgment at each stage. It says it does not sell software but delivers results. Listed services: feasibility studies, regulatory analysis, investment analysis, volumetrics, floorplans, unit-mix optimization and space planning. Site announces a $5.5M raise. Re-read Oct 18, 2026: the homepage says Davis ingests a client’s data rooms, enriches them with regulatory, market and site data gathered by its own agents, turns that into regulatory, financial and architectural constraints, and has its team validate each stage; a May 1, 2026 technology post introduces Gaudi-1, a proprietary discrete-diffusion floor-plan generation model, and claims state-of-the-art results on the RPLAN and MSD benchmarks (vendor claim, not verified).

Re-checked Oct 21, 2026: homepage unchanged in substance (reads, thinks, delivers: data rooms enriched with regulatory, market and site data by its own agents, constraints refined and validated by its team; same services list and funding banner); the Gaudi-1 technology post (May 1, 2026) is unchanged and says its in-house architects stay in the loop. Re-checked Oct 23, 2026: homepage and services list unchanged in substance; the Gaudi-1 post (May 1, 2026) and funding banner are unchanged. Re-checked Oct 25, 2026: homepage and services list unchanged in substance (feasibility studies, regulatory and investment analysis, volumetrics, floorplans, unit-mix optimization and space planning; AI paired with its own architects); the Gaudi-1 post and funding banner are unchanged. Re-checked Oct 27, 2026 (also read for a compare): homepage and services list unchanged in substance (feasibility studies, regulatory and investment analysis, volumetrics, floorplans, unit-mix optimization and space planning; data rooms enriched by its own agents and validated by its team); the Gaudi-1 post and funding banner are unchanged.Construction cost intelligence: upload architectural drawings and PLAN0 parses the sheets, runs floor plan and elevation takeoff, builds a 3D model and produces a cost estimate. The homepage (read Oct 18, 2026, which walks through a simulated demo) also shows value engineering suggestions, what-if questions in plain language that trigger a re-estimate, and material cost forecasts (a historical cost index with a 24-month AI forecast). Its YC profile says it analyzes plans with vision models, aggregates historical and real-time project data through industry partnerships for ML-driven analytics, and is building an agentic layer for cost optimization. Vendor claims, not verified: start to finish in 30 minutes instead of two weeks (homepage), and $30B of projects running through the platform (YC profile). Dollar figures on the homepage belong to a simulated demo project and are not market data. Y Combinator batch: Spring 2026 (YC company profile). Re-read Oct 19, 2026: unchanged (same simulated demo walk-through and 30-minutes-instead-of-two-weeks claim). Re-checked Oct 20, 2026: unchanged (same simulated demo walk-through, value engineering and what-if re-estimates, and the 30-minutes-instead-of-two-weeks claim). Also on Oct 20, 2026: the YC profile says $30B of projects run through the platform while its YC launch post says $20B (vendor figures that do not match; neither is used here), and the profile lists it as founded in 2026 with a team of 4. Re-checked Oct 22, 2026: unchanged (same simulated demo walk-through, value engineering and what-if re-estimates; the 30-minutes-instead-of-two-weeks line remains a vendor claim).

Re-checked Oct 26, 2026: homepage unchanged in substance (AI construction cost intelligence, drawings in and a priced building out; the simulated demo walk-through with its what-if re-estimate example; views for developers, investors and general contractors). The demo's figures are illustrative vendor content and are not used.

Where the vendor descriptions differ

  • What each sells (vendor wording): Davis lists feasibility studies, regulatory analysis, investment analysis, volumetrics, floorplans, unit-mix optimization and space planning. PLAN0 says architectural drawings in, priced building out, and its homepage demo shows sheet parsing, extracted areas and materials, a 3D model, a cost estimate, value engineering suggestions and what-if questions that trigger a re-estimate.
  • Service vs software: Davis says it does not sell software but delivers results, pairing AI with architect judgment and having its team refine and validate every stage. PLAN0 is a product you book a demo for; its homepage walks through a simulated demo of the app.
  • Where each starts: Davis ingests a client's data rooms and enriches them with regulatory, market and site data gathered by its own agents, then turns that into regulatory, financial and architectural constraints. PLAN0 starts from a set of architectural drawings and works toward quantities and cost.
  • Who they name: Davis says it works across geographies and asset classes for real estate developers. PLAN0 has views for developers (investment decisions, preconstruction, value engineering, cost forecasting), investors (independent cost validation, portfolio benchmarking, replacement cost, stress testing) and general contractors (preliminary estimates for business development, value engineering advisory, procurement planning).
  • Technology (vendor statements): Davis has published a post introducing Gaudi-1, a proprietary floor-plan generation model, with benchmark claims we have not verified. PLAN0 shows a historical cost index with a 24-month AI forecast and a confidence band.
  • Pricing (checked Oct 27, 2026): neither publishes prices. Davis's /pricing returns not found and the call to action is Book a demo. PLAN0's /pricing shows the homepage and the call to action is Book a Demo. See each tool page for detail.
  • Not used here: Davis's days-not-months claim and funding announcement, and PLAN0's 30-minutes-instead-of-two-weeks claim and the dollar figures in its simulated demo (vendor content).

Good or bad, an honest review from an estimator, PM or super helps the next team more than another vendor demo. You post under a handle; your email is never shown.

Questions to ask in your review

  • Whether you need a site's feasibility, massing and unit mix worked out, or a cost estimate for drawings you already have
  • How Davis scopes and prices an engagement, and what PLAN0 costs per project or seat; both quote after a demo
  • How either handles your local codes, cost data and markets
  • What did you use it for, on what kind of work and project size?
  • How long did setup and training take, and who on your team did it?
  • What does it cost you in practice, compared with what the sales call said?
