About Smart Split PDF
🧠 AI Detection
DeepSeek AI scans document text to identify chapters, sections, headings, and natural split points. Not just arbitrary page splits.
📑 Content-Based
Splits at logical boundaries like chapter headers, section breaks, and topic transitions. Each output file is a coherent unit.
📥 Named Parts
Each split gets a descriptive filename based on detected heading. No more "part_1.pdf" — get "Chapter_1_Introduction.pdf".
🔒 Privacy Focused
Document text sent to DeepSeek API for structure analysis only. No data stored. PDF splitting happens in your browser.
