The full list

What Albert I. Sweinstein does for you

Blueprint upload

Drop in a PDF set. Every page becomes its own searchable sheet, ready for the AI.

  • Whole drawing sets in one go
  • Sheets named by drawing number
  • Stored privately for your company

Automatic sheet reading

Albert I. Sweinstein reads every sheet on its own and pulls out the information you bid from.

  • Schedules, legends, general notes, specs and details
  • Small text read from zoomed close-ups, twice, and compared
  • Uncertain cells flagged instead of guessed

Schedules

Every schedule, cleaned up and in one place.

  • Sorted by drawing number, open one at a time
  • Header rows and symbol pictures included
  • Copy a row in one click; mark it copied for the whole team
  • Export any schedule to CSV

Legends

Every legend becomes a tidy table with the symbol picture right beside its meaning.

  • Symbol pictures cut cleanly from the drawing
  • Searchable across the whole project

Takeoff counter

Pick the sheets, press count, and walk away.

  • Choose sheets by trade: electrical, mechanical, architectural and more
  • Every area read twice and voted on; a third read breaks ties
  • Doubtful hits flagged for review, never hidden
  • Every count pinned on the drawing; add or remove with a click
  • Breaker totals by size and poles from panel schedules
  • Export counts to CSV

Ask Albert I. Sweinstein

An AI chat that knows your drawings and only your drawings.

  • Answers grounded in your project, with the sheet cited
  • Cross-checks breakers and overcurrent protection across schedules
  • Finds anomalies between plans before they become change orders
  • One shared chat per project for the whole team

Measured lengths

Total the runs of any material on top of your counts.

  • Conduit, pipe, duct and cable tray
  • Exact lengths from each sheet's confirmed scale
  • Totals per floor; export to CSV

Ask about your local code

Code questions answered from the code books you upload.

  • CEC, NEC and provincial or state amendments
  • Follows the project's province or state
  • Quotes the exact rule it used

Search everything

Find any note, spec, tag or schedule entry across every project in seconds.

  • One search box for all your projects

Works while you're away

Reading and counting run in the background, so big sets never time out.

  • Close the tab and come back to results
  • Automatic retries for busy sheets
  • Live progress when you return

Built for teams

Your whole estimating team in one workspace.

  • Invite teammates by email
  • Admins manage people and plans
  • Company data is private to your company, enforced in the database

“I read the general notes. All of them. Yes, even page 4.”
— Albert I. Sweinstein

Measured lengths

Measuring runs on top of the count. Albert I. Sweinstein traces one material's runs (conduit, pipe, duct, cable tray) across your plans and totals the lengths, per floor.

  1. 1Count your symbols
  2. 2Confirm the scale on each plan sheet
  3. 3Pick a material and press Measure

The AI only traces the runs. Lengths are worked out exactly in code from the confirmed scale, and every run is drawn on the sheet so you can check it.

Code Library

Ask Albert I. Sweinstein about regional codes and standards. Upload your company's code books (CEC, NEC, provincial or state amendments) and ask in plain English.

  1. 1Upload a code book PDF
  2. 2Set the project's province or state
  3. 3Ask a code question in the project chat

Answers quote the exact rule from your own books and only use books for the project's region plus that country's national code. A reference, not legal advice.
