## What is Elibreo?

Elibreo is a field toolkit for plumbers, HVAC techs, and electricians: code-compliant calculators, job-aware material lists, invoice scanning, and AI-powered parts identification in one app.

FREE TOOLS, NO ACCOUNT NEEDED
• 20+ trade calculators that cite the table behind every answer: gas pipe sizing (NFPA 54), wire ampacity (NEC 310.16), conduit fill and bends, voltage drop, breaker sizing, superheat/subcool, duct static, BTU-CFM, pipe offsets, pump sizing, and more
• Field tools: level, pitch, compass, protractor, reference tables for copper, PEX, refrigerant PT, and NEMA
• Jurisdiction-aware material checklists for all 50 states, plus custom lists you can build, share, and export
• Manual invoices, job folders, payables and receivables with due dates, and spending charts

AI TOOLKIT (Solo and Pro plans, 7-day free trial)
• Scan invoices: photograph any paper or PDF supplier invoice and Elibreo extracts the vendor, every line item, tax, and total, then files it to the job you choose
• Identify parts: photograph a nameplate to get make, model, full specs, manufacturer documents, replacement components, and spec-matched alternatives
• Price compare: see what you have paid for any item across suppliers over time, with best-vendor flags and margin alerts
• Ask the code: plain-English answers with the specific section citation so you can verify in your licensed code book
• Auto-translate custom lists across English, Spanish, French, Hindi, Mandarin, and Arabic

BUILT FOR THE TRADE
• Markup stays invisible on customer copies
• Vendor and customer books that sync with your phone contacts
• Export to PDF, Excel, or CSV
• Dark mode, offline calculators, and your data stays on your device

Elibreo is a reference and assistance tool for licensed and qualified trade professionals. Calculators are reference aids, not stamped engineering design. AI features are marked BETA: verify every output against the nameplate, the manufacturer's documentation, and your local AHJ before relying on it.

Solo and Pro are monthly auto-renewing subscriptions, each starting with a 7-day free trial. Payment is charged to your Apple ID; cancel anytime in Settings at least 24 hours before the period ends.
