Your paperwork, sorted

The inbox that sorts itself.

Campbooks reads your email and attachments, files the invoices, receipts, and contracts on its own, and hands you one short list of what actually needs you. So you can get back to running the business.

  • Full-text search across everything you've received
  • One-click approve, then export when you need it

Scout

An assistant that's already read everything.

Scout briefs you each morning, answers questions about your paperwork in plain language, and turns "what do I owe, and to whom" into a one-line answer.

  • A morning briefing of what needs you, nothing more
  • Ask anything about your inbox and documents
  • Drafts replies you can read, tweak, and approve
