Clean, validated invoice data for any ERP
AI pulls headers, totals, line items and references from invoices, receipts, purchase orders and statements into structured data.
IF checks, formulas and conditional logic catch wrong totals, missing fields and bad supplier IDs, or transform data on the fly.
Map any supplier alias on a document to your internal supplier ID once, and Harold applies it automatically from then on.
Shape exports to match your ERP, finance team or Zapier flow with CSV, Excel, JSON and webhook output templates.

Turn plain text into diagrams, infographics, and presentation-ready visuals.
Paste or import your text and Napkin generates infographics, diagrams, flowcharts, mind maps, and data charts that fit your content.
Napkin Slides collaborates with you to turn ideas into complete, ready-to-present decks rather than static images.
Adjust colors, fonts, layouts, and icons, reshape individual elements, and match your brand — nothing is locked after generation.
Export visuals as PPT, PNG, PDF, or SVG and drop them into PowerPoint, Google Slides, Keynote, Notion, or any tool you already use.
