What Business Problems Does This Tool Solve?
Finance, legal, HR, operations, sales... every department processes dozens of PDFs weekly. Type identification + information extraction + archiving is highly repetitive work.
Typical Pain Points:
- 100 mixed-up contracts, and you need to quickly find "the one signed with Company X last week."
- A pile of invoice PDFs, making month-end reconciliation a nightmare.
- Hundreds of research paper PDFs with disorganized research topics.
- Scanned documents requiring both OCR and categorization.
The Value of This Tool: Upload to instantly categorize, extract, and index. Turn "finding files" from "browsing through folders" into "searching by keywords."
Business Logic and Underlying Workflow
Phase 1: Batch Parsing
- Upload multiple PDFs in parallel (drag and drop to start)
- Independent OCR + text extraction + section recognition for each file
Phase 2: AI Categorization
- Built-in 12 common categories (Contracts / Invoices / Papers / Resumes / Receipts / Manuals / Reports / Emails / Legal Documents / Medical / Education / Other)
- Auto-recognition + confidence scoring
- Uncertain files are routed to the "Pending Manual Review" queue
Phase 3: Information Extraction
- Custom extraction fields based on document type (Contracts extract "Party A / Party B / Amount / Term"; Invoices extract "Invoice No. / Amount / Tax ID")
- Output structured JSON / Excel
Phase 4: Archiving + Indexing
- Build folder structures organized by category
- Generate full-text searchable index files
- Support export to Notion / Lark / Obsidian
Get Started in 4 Steps
- Log in to FlowSync → Go to the "PDF Organizer" skill
- Drag and drop to batch upload (supports 100+ files)
- Select target categories (customizable)
- Download: Categorized results in Excel + Index in JSON
