What it doesConstruction 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.
