The only AI that actually knows your jobs.
Mason is built into Ressio, so it reads every estimate, budget, schedule, and message across your jobs — then answers any question, drafts the work, and runs it on a schedule. Nothing gets created until you approve it.
Built into Ressio — construction management built for custom home builders. No extra setup, no separate login.
Not another bolt-on
Generic AI doesn't know your jobs. Mason does.
ChatGPT can't tell you which jobs are over budget. It's never seen your estimates, your schedules, or the message thread where the client changed their mind. Mason is native to Ressio — it has full context on every active job, so it answers with your real numbers and takes action on your real projects. No copy-pasting job data into a chat window.
2 of 7 active jobs are over budget
