SniffDoc: PDF & Image Finder

SniffDoc is a private PDF and image finder that searches your phone for important documents: ID cards, passports, invoices, payslips, insurance policies, bank statements, receipts and more. Stop scrolling through thousands of photos or digging through WhatsApp, email and Downloads folders. Type a few words (or speak them) and open the document you need.

WHAT SNIFFDOC FINDS

• Photos and screenshots of documents in your gallery, such as an ID card, passport, invoice, payslip, receipt or insurance policy
• PDFs and document files saved by other apps: WhatsApp and Telegram attachments, emailed PDFs, and files in your Downloads folder

SEARCH THAT FORGIVES MISTAKES

• Exact Search for precise lookups
• Similar Search handles typos and partial words: "insurence" still finds your insurance policy
• AI Search (optional, sign-in required) understands what you mean, not just the keywords
• Voice Search, including mixed-language speech
• Works offline: searching needs no internet connection

PRIVATE BY DESIGN

• Text recognition (OCR), classification and indexing all happen on your device
• Your documents are not uploaded to our servers for processing
• Local backup of your document index

HOW IT WORKS

1. Give SniffDoc access to your photos through Android's Photo Picker. For PDFs and other files saved by other apps, you can also allow All files access.
2. SniffDoc indexes your documents in the background with visible progress. Pause or resume any time.
3. Search, or browse documents automatically organized by type.
4. View PDFs right in the app, including password-protected PDFs.

WHY "ALL FILES ACCESS" IS REQUESTED

PDFs and other document files saved by apps like WhatsApp, Telegram or email are general files, not media. Android's MediaStore only indexes images, video and audio, so it cannot see them. Reliably finding them requires the All files access (MANAGE_EXTERNAL_STORAGE) permission. This permission is optional: without it, SniffDoc can only find documents you photographed, and it could not surface every important document on your device regardless of which app saved it.

WHO IT'S FOR

Anyone who has spent minutes looking for a screenshot of a passport, an invoice someone sent on WhatsApp, last month's payslip or a scan of an old bill. Students, freelancers, job seekers, small business owners, parents and anyone who handles paperwork on their phone.
