Cornerstone PM vs Projul

Two residential construction management platforms that publish their prices but deliver AI in different ways. Cornerstone PM is a newer home builder platform, still in a free beta for its first 100 builders, with a design center and a set of built-in AI agents. Projul covers builders, remodelers and specialty contractors and puts its AI behind AI Connect, which lets your own assistant work in the account. Desk research from vendor pages read Oct 27, 2026; not tested, no winner.

What it doesConstruction management software for small-to-mid home builders, in a beta it says is limited to 100 builders (pages read Oct 18, 2026): construction scheduling with Gantt charts and dependency cascades, permitting and inspections, purchasing, budgets and POs, bid management, a sales pipeline, a design center and a homeowner portal. The design center handles room-by-room selections, spec levels (for example Standard, Premium, Luxury), structural options with real-time pricing, per-room allowances that roll overages into change orders, a step-by-step product configurator for items such as cabinets and countertops, and a Trade Copy of selections with all pricing stripped for trades. Its AI agents: StyleSmith AI, which a design or sales user points at a home and one of 10 style themes to compose a whole-home selection set (flooring, tile, cabinets, counters, plumbing, lighting, hardware) from the builder's own catalog at its own retail prices, held inside the home's spec floor and an optional ceiling; the vendor says it reports a gap rather than substituting a higher tier, writes into selections only on command, never overwrites approved or locked selections, never touches structural options and never auto-approves. A buyer style quiz that feeds it is in early access. Also listed: Foreman AI (a natural-language agent with 396+ skills over parts, vendors, homes and budgets, with undo and dry-run on destructive writes), Blueprint AI (PDF floor plan to scope takeoff), Bid Import AI (vendor bids from Excel, PDF, scans or photos into bids or takeoffs, with a confidence table to review), Punchlist AI, an AI MLS listing writer, an AI support agent, and Jobsite AI vendor-arrival detection (listed as coming soon). A built-in MCP server and a REST API with webhooks let Claude, ChatGPT, n8n or your own agent use the same skills on Pro+. The pricing page's comparisons with NEWSTAR, BuildPro, Buildertrend and JobTread are vendor claims and are not used here. Re-read Oct 19, 2026: the AI agents page is unchanged in substance (Jobsite AI still coming soon). Re-checked Oct 20, 2026: unchanged in substance (StyleSmith AI on Pro+ and Enterprise, with the buyer style quiz still in early access and enabled per account; Jobsite AI still coming soon); the menu also tags Punchlist AI as New and lists a CRM Migration Wizard, live in beta, that maps a Buildertrend or JobTread export, and the pricing page describes a built-in MCP server for Claude Desktop, Cursor and Windsurf alongside the REST API on Pro+. Re-checked Oct 22, 2026: unchanged in substance (StyleSmith AI on Pro+ and Enterprise with the buyer style quiz still in early access; Jobsite AI still Coming Soon; Punchlist AI tagged New; CRM Migration Wizard still Live in Beta; MCP server and REST API on Pro+). The menu now also lists a Jobsite Command Center with live QR check-ins, a vendor map and a real-time activity feed, and calls the AI line-up seven AI agents. The AI agents page tags Bid Import AI as Pro+ while the pricing page lists it from Pro. The pricing page's cost comparisons with other builder software are still vendor claims and are not used. Re-checked Oct 23, 2026: unchanged in substance (StyleSmith AI on Pro+ and Enterprise; Jobsite AI still Coming Soon; Punchlist AI tagged New; CRM Migration Wizard for Buildertrend or JobTread exports still Live in Beta; MCP server and REST API on Pro+). The Pro+ card says Foreman AI runs on Claude Sonnet 4 (vendor statement). The homepage says 5 built-in AI agents while the menu says seven. The site's pages link an llms.txt and an ai-plugin file in their metadata (not followed). Cost comparisons with other builder software are still vendor claims and are not used. Re-checked Oct 25, 2026: pricing page unchanged in substance (AI agents in the menu including Foreman AI, StyleSmith AI, Punchlist AI and Bid Import AI; Jobsite AI listed for vendor arrival detection; CRM Migration Wizard for Buildertrend or JobTread exports still Live in Beta; REST API and webhooks to bring your own AI agent; free beta still limited to the first 100 builders, with standard pricing after the slots are gone). Cost comparisons with other builder software and skill counts are vendor claims and not used. Re-checked Oct 27, 2026: homepage and pricing page unchanged in substance. Competitor price comparisons on the vendor's pricing FAQ are vendor statements and not used.Construction management software for residential builders, remodelers, restoration and specialty contractors: CRM and lead capture, estimates and change orders, e-signatures, invoicing and payment processing, progress billing, scheduling with Gantt charts and linear timelines, job costing and budgeting, purchase orders, a client portal, a mobile app with geofenced time tracking, daily logs, Spanish translation and QuickBooks integration. Its AI is Projul AI Connect (page read Oct 18, 2026): an API key that lets an AI assistant such as ChatGPT or Claude (the page also names developer tools Cursor, Windsurf and Claude Code), or Zapier, Make and n8n, work in the Projul account, for example turning a voicemail into a lead, drafting an estimate or change order from notes, shifting a schedule or updating a cost library from a supplier price list. Projul says the assistant can build and edit draft estimates and change orders but cannot send or approve them or text or email customers, that totals, taxes and markups are calculated by Projul rather than the AI, and that only owners and admins can create a key, read-only or read-write, which can be turned off at any time. The pricing FAQ places AI Connect on the Pro plan. Vendor says 5,000+ contractors use Projul (vendor claim, not verified by us). Re-read Oct 19, 2026: the AI Connect page no longer names Gemini, and its FAQ says AI Connect does not yet create or send invoices or work with the time clock, timesheets, payroll, daily logs or purchase orders. Re-read Oct 20, 2026: unchanged in substance; the homepage still lists Spanish translation and the AI Connect page still does not name Gemini. Re-checked Oct 22, 2026: homepage unchanged in substance. The AI Connect page now says AI Connect is an MCP (Model Context Protocol) server, so any AI tool that supports MCP connectors, including ChatGPT, Claude, Cursor and Windsurf, can connect with an API key from Projul settings, and adds FAQ entries on running the software from ChatGPT or Claude; it still says estimates and change orders stay drafts until someone on the team sends them. The 5,000+ contractors line and review-site ratings are vendor material and not used. Re-checked Oct 23, 2026: homepage and AI Connect page unchanged in substance (AI Connect is an MCP server for ChatGPT, Claude, Cursor, Windsurf and other MCP-capable tools, connected with an API key; estimates and change orders stay drafts until a team member sends them). Contractor counts and review-site ratings are not used. Re-checked Oct 25, 2026: homepage and pricing page unchanged in substance (Run Projul from ChatGPT, Claude and more; Projul AI Connect on the Pro plan only per the pricing FAQ). Contractor counts, review-site ratings, profit and time-saved figures and the ROI calculator are vendor material and not used. Re-checked Oct 27, 2026 (also read for a compare): homepage, pricing and AI Connect pages unchanged in substance (AI Connect is an MCP server for ChatGPT, Claude, Zapier and similar tools; estimates and change orders stay drafts until sent).
