This path is for you if a photo of a receipt or a scanned contract needs to become text you can check, not a guess in a chat. It is the vision and document path: what the model can read, and where a human still has to look. No part is live on this page yet. Start with Practical AI for what not to paste, and come back when part 1 is up.
- 1 Photos of Paper to Useful Text: How OCR and Document Extraction Actually Work Build document capture as a pipeline: correct the image, detect text, then extract structure. Classic OCR still matters before any LLM reasons. Scheduled · January 14, 2027
- 2 LLM Vision vs Classic OCR: When to Read, When to Reason Hybrid document AI: OCR for precise text and numbers, vision LLMs for semantic layout and messy handwriting. Do not let fluent models invent totals. Scheduled · January 15, 2027
- 3 Document AI Pipelines for PDFs and Scans: Architecture, Layout, and Chunks Detect PDF type, preserve reading order, and chunk on layout before you embed. Columns and tables break if you slice by character count alone. Scheduled · January 16, 2027
- 4 Docling and Open Extraction Stacks: Local Document Processing Without Cloud Lock-In Run open document tools like Docling on CPU or GPU for private, batch extraction. Keep cloud APIs for spikes that need managed scale. Scheduled · January 17, 2027
- 5 Extracting Tables, Invoices, and Structured Fields: Beyond Plain Text OCR Extract structured documents with table geometry plus schema validation. Plain text dumps are not invoice systems. Scheduled · January 18, 2027
- 6 Human-in-the-Loop Document Verification: Designing Failure-Proof Accuracy Gates Design document AI with confidence scoring and human review queues. High softmax alone is not a payment authorization. Scheduled · January 19, 2027
- 7 Document AI Privacy and Compliance: Sanitizing Secrets, PII, and Regulated Data Sanitize document AI inputs at the byte layer before OCR or LLM vision. Overlays and cloud defaults are not enough for PHI, PII, and regulated filings. Scheduled · January 20, 2027
- 8 When a Scanner App and Good Lighting Are Enough: The Practical Field Guide Use good lighting and a scanner app when field capture quality matters more than fancy models. Save heavy document AI for pages that still fail after clean scans. Scheduled · January 21, 2027
