Show HN: Parseflow – Extract data from any document. Entirely on your Mac (www.parseflow.io)

ParseFlow, a new software tool designed for Mac users, allows for the seamless extraction of data from PDFs into structured formats like spreadsheets. Users can define custom templates specifying what data to extract—such as invoice numbers and totals—utilizing a visual schema editor. With the capability to process up to 100 PDFs simultaneously in the background using a local AI model, ParseFlow ensures that users' documents remain private, as no data is sent to the cloud. Operating offline after a one-time model download, the tool offers real-time progress monitoring, alongside a user-friendly interface that features side-by-side reviews of extracted data and original documents. This tool is significant for the AI/ML community as it leverages Google's open-source Gemma 3 multimodal model running on-device with Metal GPU acceleration, making it a competitive alternative to subscription-based cloud PDF extractors. The one-time payment model (€17.99) eliminates persistent fees and usage limits typical of cloud solutions, enhancing accessibility and cost-effectiveness for professionals. Additionally, its GDPR-friendly design emphasizes strict privacy standards, providing a compelling case for users concerned with data security while simplifying the document processing workflow.
