FolioBookmark Long-Document Bookmark Studio

Batch-generate verifiable multi-level bookmarks and searchable PDFs for long documents

Problem

People handling long PDFs, scans, and technical manuals often have no bookmark structure, forcing page-by-page manual work, and untagged books are painful to search. Someone built a strengthened regex-based bookmark auto-generation and adjustment feature into an open-source PDF editor, showing this is a recurring step in long-document workflows. General PDF editors are either too heavy or weak at bookmarks, and scans lack offline OCR.

Solution

A tool focused solely on long-document bookmarking: batch-generate and adjust multi-level bookmarks via regex or layout rules, run offline OCR on scans to produce searchable double-layer PDFs, and preview the structure before applying. Works alongside existing PDF editors instead of trying to be one.

Users

Academic researchers, technical writers, legal and archive staff who regularly work with long PDFs

MVP

Import PDFs and generate bookmark candidates by layout rules; regex-based level adjustment; offline OCR into double-layer PDFs; structure preview and export; Windows/macOS desktop first

Revenue

Buy-once desktop tool with page/OCR limits in the free tier; premium unlocks batch processing and automation scripts

Why now

Scans and long documents still circulate as PDFs, AI OCR costs are falling enough to make offline processing viable, and big PDF vendors ignore the narrow bookmarking niche
