Why deterministic
An estimate is a commitment. The numbers in it should come from the drawing, not a model's best guess.
Counts come from the drawing itself, the shapes the CAD system drew, not a probabilistic guess over pixels. Re-run a sheet a hundred times and the totals never move. When a count is challenged at tender stage, click any number and see every location it came from.
AI does what it's good at (reading legends, pre-sorting the review queue) and nothing else. Every count is deterministic, and every uncertain detection waits for a human decision. No hallucinated totals in your bid.
Distinctive symbols confirm automatically. Look-alikes and edge cases land in a review queue you clear with two keys. A sheet that took an afternoon of clicking becomes minutes of review.
Workflow
Drop the tender PDF: the whole package, as it came.
Every symbol the legend defines is counted, sorted into its class.
Confident counts confirm themselves; you decide the rest from the keyboard.
Finalize and export XLSX or CSV, traceable back to the drawing.
Features
The legend on the sheet defines your classes: every row becomes a counted symbol type, labels included.
Legend drawn as an image, or on a cover sheet? Drag a box around it and AI reads the rows for you.
Thumbnails of every flagged detection: j/k to move, y/n to decide, per-class bulk confirm.
Place a few symbols by hand and EasyTakeoff recovers the rest of the family across the sheet.
Tender packages stay grouped: one project per job, per-sheet progress, quick switching while you work.
Finalized counts export to a clean spreadsheet (class, count, sheet), ready to price. CSV too.

Questions
Precision-first: a count only confirms automatically when the match is distinctive. Everything uncertain goes to review, never silently into your totals. Every number can be audited back to its locations.
PDF drawing sets. CAD-exported sheets give the best results, and scanned drawings are fully supported. DWG import is on the roadmap.
Stored encrypted in the UK (London region), scoped to your organization, never used to train models. Deleting a drawing set removes the file.
