CogniBill

AI Estimates & PDF Invoices

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Describe the job and let AI draft the details. Create a polished estimate or invoice PDF, then share it by Messages, Mail, AirDrop, WhatsApp, or print it. Turn a job description into a customer-ready estimate. CogniBill helps solo contractors, tradespeople, and freelancers move from a customer request to a polished PDF without wrestling with spreadsheets or heavyweight accounting software. DESCRIBE IT. REVIEW IT. SEND IT. Tell CogniBill what the customer needs in your own words. AI can organize the customer, job title, line items, quantities, and rates into an editable draft. Review every detail, make changes, and create the document when it is ready. Choose Apple Intelligence on supported devices, or connect your own OpenAI-compatible API service. Compatible services may include providers such as DeepSeek, depending on the endpoint and model you configure. Third-party AI use requires your own service credentials and may be subject to that provider's terms and charges.

LOCAL-FIRST AND STRAIGHTFORWARD Your core business records are stored locally on your device. Create and manage documents without a connection; online AI services naturally require network access. The free version supports up to 3 new documents per month. A one-time purchase unlocks unlimited documents, all templates, and reports—no recurring subscription. Important: CogniBill creates business documents and records payment information. It does not process payments, issue government-certified tax documents, or provide legal, accounting, or tax advice. Always review AI-generated content and confirm local requirements before sending a document.
