Comparison reflects Struvia's free takeoff offering and how the two products approach takeoffs.
Reading by the page, with optional AI takeoff
A real takeoff workbench — not a stripped-down trial. Manual measuring is unlimited; automated takeoffs use credits and show an estimated cost before measuring.
Upload real plan sets
Upload a PDF plan set. Reading and sorting the sheets costs about $0.07 a page.
Unlimited on-screen takeoff
Set scale, measure lengths and areas, count fixtures, and organize by cost code — no per-seat license, no caps.
AI plan chat
Ask questions about your blueprints and get answers cited to the sheet — 0 messages a day, free.
AI auto-measure
Automated takeoffs use credits. See an estimated range before measuring and check the quantities against the plan.
Sheet-smart viewer
Pages are classified automatically (floor plans, schedules, details) so you jump straight to the sheets that matter.
Cloud-based, your data
Runs in your browser. Plans, measurements, and takeoffs live in your account — upgrade or export whenever.
Rather not do the takeoff at all?
The free plan is you doing the takeoff, with AI assists. The paid product is Struvia doing it for you:
- Full AI takeoff and estimate on every plan — no hand-measuring
- Premium AI models with unlimited chat and measurements
- Automatic subcontractor outreach, bid collection, and leveling
Free STACK alternative FAQ
Is Struvia a free STACK alternative?
Yes for takeoffs. Create an account and you can upload plans, view them sheet by sheet, and measure and count on-screen — manual takeoff is unlimited and free forever, with no per-seat license and no trial countdown.
Is it cloud-based like STACK?
Yes. Struvia is fully web-based — nothing to install, and your plans and takeoffs are saved to your account so you can pick up from any browser.
What does the AI do beyond on-screen measuring?
Struvia's AI answers questions grounded in your blueprints. 0 chat messages a day are free. Automated takeoffs use credits; you see an estimated cost before measuring.
What happens when I hit a free limit?
Nothing breaks. Manual measuring keeps working, your plans and measurements stay yours, and the AI allowances reset automatically — daily for chat, monthly for the rest. Upgrade any time for more.
How is the paid product different?
The free plan is a takeoff workbench: you do the takeoff, with AI assists. The paid product is a service: Struvia runs the full AI takeoff and estimate on every plan, then automates subcontractor outreach, bid collection, and bid leveling on top.
