| Sheet row | Togal.AI | STACK |
|---|---|---|
| Category | Takeoff | Takeoff & estimating |
| AI role (our label) | AI-first | AI features added to established product |
| What it does | AI-powered takeoff tool that the vendor says automatically detects, measures, and compares spaces and features on drawings, with cloud collaboration, drawing-set comparison, and a Togal.CHAT feature for querying plans. Vendor claims up to 98% accuracy on floor plans (vendor claim, not verified). | Cloud-based construction software covering digital takeoff, estimating and proposals, and field/project management ("Build & Operate"). The vendor now describes STACK as an AI preconstruction platform: AI that reads uploaded sheets, auto-names pages, and flags revisions; AI auto-counting of symbols and suggestions of scope that may be missed; and AI described as pressure-testing pricing and flagging risk, gaps, and pricing drift in estimates. Unlimited viewer seats. |
| Who it's for | Estimators (vendor describes it as "built by estimators, for estimators"). | Specialty contractors, general contractors, suppliers and manufacturers, owners and developers. |
| Pricing (as publicly stated) | Per-user subscription. Growth plan listed at $299/mo per user, billed yearly. Business plan: custom pricing for teams with 4+ users.

Where the vendor descriptions differ
- Approach: Togal.AI is AI-first, describing automatic detection, measurement, and comparison of spaces and features on drawings, plus Togal.CHAT for querying plans. STACK describes AI that reads and auto-names sheets, flags revisions, auto-counts symbols, suggests possibly missed scope, and pressure-tests estimate pricing.
- Scope: STACK also covers estimating, proposals, and field/project management (Build & Operate). Togal.AI is focused on takeoff, with drawing-set comparison and cloud collaboration.
- Pricing: Togal.AI's Growth plan was listed at $299/mo per user, billed yearly, with custom Business pricing for 4+ users. STACK lists Takeoff & Estimate at $299/user/mo, Build & Operate at $49, and the full platform at $348, with a free version of Takeoff & Estimate.
- Seats: STACK lists unlimited viewer seats. Togal.AI's Business plan is for teams with 4+ users.
- Claims: Togal.AI claims up to 98% accuracy on floor plans (vendor claim, not verified). We recorded no accuracy figure for STACK.

What we can't tell you yet
Which tool is better for your work. That needs testing on the same package with a verified answer key. Planned measures for this comparison:
- Quantity error against a verified answer key on a civil bid-item schedule
- Missed items and false counts
- Minutes to first result and minutes for an estimator to correct the output
