FileNook is a private local file workspace for iPhone and iPad. Organize files, read documents and prepare materials without a cloud-drive account. Files and document processing stay on your device unless you choose to share them. FILE WORKSPACE • Create folders; browse, rename, move, duplicate, sort and search files. • Use favorites, recent files and a recoverable trash. • Import from Files, Photos, AirDrop and the share sheet. • Transfer files from a computer over local Wi-Fi—no account or upload to a cloud service. • Search supported document content and inspect detailed file information. SCAN & RECOGNIZE • Scan ID cards with optional purpose watermarks and image enhancement. • Extract editable text from photos and PDFs. • Extract tables with cell review and export to Excel. • Recognize QR codes without automatically opening links. • Transcribe local audio with selectable ranges and TXT or SRT export. PDF TOOLS • Create searchable or standard PDFs from photos and document scans. • Merge PDFs; organize, reorder, rotate, insert, remove and extract pages. • Split PDFs by page, fixed groups or custom groups. • Crop page margins, compress PDFs and password-protect PDF copies. • Convert PDFs to images or editable Word documents. • Export TXT and Markdown to PDF; add optional covers, contents and page numbers. • Combine photos, scans and selected PDF pages; set a consistent A4 or Letter page size. PHOTO & PRIVACY TOOLS • Convert image formats, crop or resize to exact dimensions, and save reusable material presets. • Compress photos, combine images and stitch long screenshots. • Add text watermarks to images or PDFs. • Permanently redact selected areas of images and PDFs before sharing.
