Loading the page…Every tool, on one canvas.
The full workspace for plan-set takeoff. AI reads the drawings and the specs. You measure, compare revisions, and ship the bid from the same browser tab.
Ollie is siding takeoff software built for the exterior envelope: siding and panel systems, roofing takeoff, air and water barriers, trim and flashing. Every tool below is shaped by exterior estimating, where one elevation carries five scopes and each layer needs its own line on the bid.
AI Detect
Every callout knows its sheet before you do.
A plan set buries hundreds of detail callouts, and each one is a page-flip to nowhere. AI Detect reads the drawing in a single pass and resolves every reference to the sheet it points at, whether the PDF carries a real text layer or it's a scanned image with none. Hover a callout, the right page opens.
- Text-layer scan reads embedded PDFs instantly, at no cost.
- Shape-and-OCR scan handles scanned, image-only sets.
- Aliasing matches A-000, A0.00, and A000 to the same sheet.

Markup tools
Stop bouncing between tools to measure one wall.
Area, linear, count, dimension, highlight, sticky note. Every tool a takeoff needs, on the page you're already looking at. Snap to angles and grid, draw bezier arches when the wall curves, and calibrate scale by clicking two known points or let auto-scale read the title block. Every measurement carries its sheet code, so the master sheet always knows where the number came from.
- Area, linear, and count, all on one canvas. No tool-switching.
- Calibrate scale in two clicks, or auto-scale from the title block.
- All Items rolls up the set; current-sheet list shows the page.

Cross-set compare
Catch the addendum before it costs you the bid.
Overlay 50% on IFC. Overlay IFC on 100%. Moved openings, resized walls, new details appear where they changed. Run it page by page, or batch the entire set. The change summary describes what moved in plain words instead of a pixel diff.
- Auto-pairs sheets by code, even when pages renumber.
- Tint + opacity controls for single-set markup, red/blue for direct compare.
- Transfer measurements from old set to new with inverse overlay transform.

Assembly Builder
One roof. Nine layers. You trace it once.
Vapor barrier. Three lifts of iso. Cover board, membrane, crickets. Every layer is its own line on the estimate, every line is the same square footage, and you draw that same roof again for each one? Then the next job comes in and you retype the whole stack from memory. Build the assembly once from your org's catalog and trace the roof a single time. All nine layers quantify with it. Crickets and tapered iso still measure on their own, because the catalog already knows they do.
- Layers inherit the roof SF. Separate-takeoff items measure on their own.
- Your org’s catalog, not a blank box. Admins edit it, everyone builds from it.
- Save an assembly to the project, to yourself, or to the whole org.

Project Chat
The answer's in the documents. Now it's in seconds.
It's four o'clock on bid day and the parapet height is buried somewhere in two hundred pages. Project Chat reads every drawing, spec section, and addendum at once, answers in plain words, and cites the page it pulled the answer from. Ask where the drawings and specs disagree and it lists every conflict before it turns into an RFI.
- Cites pages with [A-201] / [S-301] chips that jump to the source.
- Flags discrepancies between the drawings and the specs.
- Searches drawings, specs, addenda, and your own notes.

Based on the specs, what roofing material should be included in the estimate?
Roofing for 1026 Olive Ave, per Section 075300178:
- Membrane: 0.060" non-reinforced black EPDM, fully adhered181
- Insulation: poly-iso, R-25 min, 4.5" tapered182
- Cover board: ISO 95+ HD at the 20'-0" perimeter183

Takeoff data
Never re-key a measurement into a bid sheet.
Your marks on the plan are already the quantities. They shouldn't get retyped into Excel by hand. Group measurements into items, nest items into folders, and add a waste percent, a pitch factor, or a custom formula column. The master sheet rolls everything up across sheets and sets, then leaves as a field-ready PDF or a bid-ready XLSX with the math intact.
- Formula engine supports SUM, COUNT, IF, AND, OR, AVERAGE, MIN, MAX.
- Pitch factor from 1/12 to 12/12, with flat footage tracked alongside.
- Custom columns scoped to the project, never bleed across.

Project library
Find any sheet without opening five PDFs.
Plans, specs, addenda, and your own sketches arrive as a pile of separate files. Sort them into Plan, Spec, and Other sets, nest pages into folders at any depth, and run one full-text search across the whole job. It lands on the page with the match highlighted. Sheet codes get detected automatically; fix them by hand when the title block lies.
- Full-text search across the plan set or the spec book.
- Blank sketch sheets · US Letter, Tabloid, A3, A1, with or without grid.
- Bookmark folders for the pages you return to most.

Team
Save the project without stepping on your coworker.
Live presence shows who is in the project. Each save merges per-user changes, so two estimators on the same project never overwrite each other. Share by member, by role: Admin, Estimator, Viewer. The activity log records every open, upload, and major change.
- Per-user field merge · items, measurements, highlights all isolated.
- View-only role enforced server-side, not just hidden in the UI.
- Activity feed scoped to the org, visible to admins.

Export
Export to Excel. Skip the reformatting.
The bid sheet shouldn't need an hour of cleanup after it leaves the takeoff. Print selected pages with or without the takeoff overlay as a PDF, or export the master sheet as XLSX with every item, folder, custom column, and total intact, the folder hierarchy preserved as nested rows. No reformatting in Excel.
- PDF export keeps measurements, dimensions, highlights, and notes.
- XLSX preserves folder hierarchy as nested rows.
- Print preview shows exactly what hits paper.

Ollie's AI features are assistive, not authoritative. They misread drawings, miss callouts, and get scales wrong, particularly on scanned or hand-marked sets. Every number you bid on is yours to verify against the drawing.
Your drawings. Your takeoff. Your call.
The AI does the reading. You complete the takeoff. Free to start, no install.
