Comparison
PreCal-IQ vs. Togal.AI
Togal.AI and PreCal-IQ both call themselves AI takeoff tools, but they solve different parts of the takeoff problem. Togal.AI is excellent at vision-based measurement and counting on drawings — it's built by estimators and earns its accuracy claims on geometric extraction. PreCal-IQ adds an upstream layer: it reads the CSI spec book end-to-end, resolves hardware groups and finish schedules, and ties every line item back to the spec section that defines it. For projects where the spec drives the scope, that distinction matters.
Bottom line
Togal.AI is an AI plan-reading tool that auto-detects rooms, walls, doors, and similar elements on architectural drawings — a strong fit for estimators who want faster drawing takeoff. PreCal-IQ goes one layer deeper: it reads the spec book alongside the plans and cross-references both, so the takeoff includes specification-dependent items (hardware groups, finishes, fire ratings) that drawing-only AI can't resolve.

Side-by-side
| Feature | PreCal-IQ | Togal.AI |
|---|---|---|

| Reads CSI spec PDFs | Yes — extracts every line item from the spec book | No — drawing-only |
| Resolves hardware groups / finish schedules | Automatic from spec sections 08 71 00, 09 90 00, etc. | Estimator looks up in the spec manually |
| Cross-references spec to plans | Every line item linked to spec section + drawing location | No — drawing measurements only |
| Drawing comparison / addenda | Yes — diffs old vs. new across spec and plans | Yes — single-click drawing diff |
| CSI coverage | All 45 CSI categories from one upload | Per-trade workflow |
| Vendor pricing portal | Built-in — vendors price the takeoff directly | Not included |
| Starting price | $499 / mo (Starter plan) | $299 / user / month (Growth) |
In practice
How each holds up under real workflow
A 200-door interior project where hardware groups drive the bid
Togal.AI counts the doors from the drawing accurately. The estimator still has to open Section 08 71 00, match each door type to its hardware group, and assemble the takeoff manually. PreCal-IQ does both passes — counts the doors AND resolves the hardware group from the spec — in a single run.
A 600-page spec book that drives scope but isn't shown on the drawings
Specifications often define scope that doesn't appear in the drawings: testing requirements, allowances, mock-ups, owner-furnished items. Togal.AI doesn't read the spec book at all, so this scope stays invisible until an estimator manually catches it. PreCal-IQ extracts every spec-defined line item and surfaces it as part of the takeoff.
A small team doing geometric measurement on simple plan sets
For projects where the drawing IS the scope — small commercial fit-outs, residential, single-trade work — Togal.AI's drawing-first workflow can be faster to set up because there's less to read. The per-user pricing also scales gently for very small teams. PreCal-IQ wins as project complexity and spec depth increase.
FAQ
Common questions
Does Togal.AI read spec books like PreCal-IQ does?
No. Togal.AI is positioned as an AI tool that detects and measures elements directly from drawings — its strength is vision-based geometry, not spec-text extraction. PreCal-IQ reads the CSI spec book in addition to the plans and cross-references both.
Is Togal.AI cheaper than PreCal-IQ?
For very small teams the per-user pricing models are close — Togal.AI starts at $299/user/month (Growth, billed annually); PreCal-IQ Starter is $499/month for one user and Professional is $1,499/month for three users. Per-seat economics flip in PreCal-IQ's favor on teams of 3+.
When is Togal.AI the better choice?
When your bid scope is fully defined on the drawings and the spec book is light or generic — small commercial fit-outs, residential interiors, single-trade work. Togal's drawing-first workflow is also a strong fit if your team already has a separate spec-review process they don't want to change.
Can I use both PreCal-IQ and Togal.AI?
In principle, yes — but they overlap on the drawing-parsing step, so most teams pick one. If you're already a Togal customer, PreCal-IQ adds the spec-reading and cross-referencing layer; we'll happily walk you through where the workflows complement vs. duplicate.
