ProofBox Vault is the private claim organizer built for real-life headaches: flight delays, damaged packages, landlord deposit disputes, card chargebacks, return fights, and insurance paperwork. Drop in screenshots, chat exports, receipts, photos, PDFs, and notes. ProofBox extracts key details, builds a timeline, keeps every supporting file tied to the case, and helps you turn scattered evidence into something a business, bank, landlord, merchant, or carrier can actually review. With ProofBox Vault you can: - Import screenshots, photos, PDFs, and text files into one case - Extract dates, amounts, order numbers, and references locally on device - Build a clean chronology from imported evidence - Edit facts, follow-up reminders, and key timeline events - Generate complaint drafts with scenario-based remedy templates - Export a shareable PDF claim summary - Track requested remedies, response deadlines, outcomes, and archive notes ProofBox Vault is designed for people who do not want to lose money just because their evidence is messy.

DocLens

DocLens is a fully offline frame-select OCR tool: draw a box, extract exactly the text you circled, and translate it on your device. The liability clause in a contract, the date on a court ruling, one verbatim line from an interview: you choose the block, it reads only that. Headers, footers, ads and noise are never touched. Key features: 1. Frame-select OCR: shoot or pick a photo, drag a box, and only the text inside is recognized. Low-confidence lines are dashed-underlined for line-by-line proofreading before translation. 2. Accurate recognition: selectable recognition languages with automatic per-line detection for mixed Chinese and English; handwriting and rotated text supported; Enhance and Retry rescues poor scans. 3. On-device translation: results are translated paragraph by paragraph for fluent output. Chinese, English, Japanese, Korean, French, German and Spanish are supported, and language packs can be downloaded in advance. 4. QR and barcode scanning: frame a code to open URLs in an in-app browser, dial numbers, compose emails, open locations, or copy Wi-Fi passwords and contact fields. 5. Fully offline: recognition, translation and barcode scanning all run on your device. No account, no analytics, no cloud upload, and no network access from shutter to text. 6. Minimal permissions: DocLens never asks for full photo library access, only permission to save your exports. Data stays in the local sandbox and database. 7. Torch and Enhance Retry: turn on the light for close-up documents, and re-run recognition with boosted contrast when a scan comes out poorly. Membership: New users get a free 7-day trial, extendable once by another 7 days from the membership page. After the trial, you can still scan free once per day. VIP is a one-time purchase: no subscription, no ads, no tracking. Great for contract review, hearing and meeting notes, interview transcription, research excerpts, receipt and form data extraction, and translating foreign signs. Your files go nowhere. That is what makes DocLens different: it does not make decisions for you. It hands judgment back to you, and keeps privacy structural with on-device computing.

Verdict
The clearest difference is in-app purchases: DocLens at none against ProofBox Vault's 1. DocLens also leads on update cadence (every 10 days vs every 4 months). On price, ads, device support and iOS requirement there is nothing between them.
