LumenScan vs Smallpdf

LumenScan is a mobile document scanner for Indian paperwork, with tools to recognize text, extract GST details, mask Aadhaar numbers, and sign PDFs on the device. It runs on Android and iOS. Its on-device OCR works offline and reads English, Hindi, Tamil, and Telugu. The app detects page edges, corrects perspective, reduces shadows, and exports PDF, JPEG, PNG, or Word files. Scans are sorted into categories such as IDs, invoices, receipts, legal documents, and notes; tags, favorites, and full-text search help organize them. Security options include a biometric vault, Aadhaar and PAN masking before sharing, and password-protected PDF exports. The maker says scans and OCR text are not uploaded to its servers, though anonymous product analytics and crash diagnostics are enabled by default and exclude document contents and personal details. The free plan includes daily scans, PDF export, and on-device OCR. Pro monthly costs ₹149 per month; Pro yearly is ₹999 per year and includes a 7-day trial. The listed lifetime option is ₹2999 per month, with a one-time payment and no renewal.
