About this tool
Extract vendor, invoice number, dates, amounts, and line items from invoice PDFs/images. OCR + AI. 100% local, no upload, free.
What Is the AI Invoice Extractor?
The AI Invoice Extractor is a free browser-based AI tool that performs invoice extractor tasks entirely on your device using in-browser machine learning models. Unlike cloud-based AI services that send your data to remote servers for processing, this tool downloads the model once and then runs completely offline — your text, images, or documents never leave your browser. The AI engine uses optimized WebAssembly and WebGL for near-native inference speed. It supports invoice OCR capabilities and handles multi-language input. No API key, no account, no subscription — the tool is completely free with no usage limits.
Who Should Use This Tool?
Content creators use this tool for invoice extractor tasks without worrying about their drafts being stored on third-party servers. Professionals in regulated industries (legal, healthcare, finance) use it to process sensitive invoice OCR data while maintaining client confidentiality. Students use it as a free alternative to paid AI services for learning and research. Developers integrate invoice data extraction capabilities into their workflows without API costs. Privacy-conscious users prefer it over cloud alternatives because there is no telemetry, no logging, and no data retention. The tool is especially valuable in regions with limited internet connectivity after the initial model download.
How to Use the AI Invoice Extractor
The first time you use the tool, it downloads the AI model (typically 20-80MB depending on capability). After that, it works fully offline. For invoice extractor tasks, enter or paste your input text into the editor. Select your desired options — tone, style, language, or output format. Click the generate button and the AI processes locally, typically returning results in 2-10 seconds depending on input length and model size. Results appear in the output panel where you can edit, copy, or download them. Your input and output are never transmitted or stored on any server.
Frequently asked
What specific data fields does it extract from invoices?
It extracts: vendor name and address, invoice number, issue date, due date, subtotal, tax amount (with rate), total amount due, payment terms, and individual line items (description, quantity, unit price, extended price). Output is structured JSON or CSV, ready for import into QuickBooks, Xero, or FreshBooks accounting software.
Can I batch-process multiple invoices at once?
Yes. Upload multiple invoice PDFs or images, and the tool processes each sequentially, extracting all fields and compiling results into a single CSV export. A batch of 20 invoices processes in 2-4 minutes. This eliminates manual data entry that typically takes 3-5 minutes per invoice—saving 1-2 hours for a 20-invoice batch.
Does it upload my financial documents?
No. OCR (Tesseract.js) and data extraction run entirely in your browser. Invoice images and extracted data never leave your device. This is critical for accounting firms handling client financials under confidentiality agreements and businesses subject to SOC 2 or PCI-DSS data handling requirements.
