FAQs
What are the major differences between Beam AI and Stackct Takeoff?

Beam AI is a fully automated Stack alternative that delivers ready-to-use quantities—no manual tracing, clicking, or sheet-by-sheet review. It adds human QA, automated spec and revision detection, discrepancy alerts, unlimited users, and 24×7 support.
Stack offers strong digital takeoff tools but relies on the user to measure, review plans, and validate accuracy manually. For teams seeking more automation and less effort, Beam AI is the more advanced Stack software alternative.
Is Beam AI and Stackct available for Mac users?

Yes—both work on Mac via a browser. Beam AI, however, is a fully cloud-native Stack Mac alternative with no downloads or manual setup, and it automates the entire takeoff process. Stack also supports Mac, but the workflow remains user-driven. For Mac teams wanting more automation, Beam AI is the stronger Stack alternative for Mac.
Does Beam AI offer more automation than Stackct?

Yes. Beam AI fully automates takeoffs by reading plans, elevations, sections, and specs to produce ready-to-use quantities. Stack offers helpful measurement tools but still relies on manual work. That’s why Beam AI is seen as the better alternative software for Stack for teams seeking true AI-driven automation.
Which platform is better for team collaboration?

Both support collaboration, but Beam AI offers unlimited software users, real-time collaboration with multiple stakeholders, shareable links for external teams, and adding notes/tags to your takeoffs to communicate with PMs etc. For teams managing multiple simultaneous takeoffs, Beam AI is the more scalable Stack alternative.
Are there free alternatives to Stackct for small contractors?

Beam AI is not a free tool, but there are limited free alternatives to Stack with basic measurement capabilities—these are usually manual and lack automation. Small contractors looking for a Stack free alternative that offers true automation typically find that Beam AI saves enough time and labor cost to pay for itself quickly. Contractors have been able to 2-3X their bid volume after adopting Beam AI.
