Key Facts
AI Document Restore is powered by Gemini/GPT-4o/Claude multimodal vision model with high accuracy across various handwriting styles and ink colors.
The feature uses AI to distinguish printed content (questions, headers) from handwritten content (answers, annotations), removing only the handwriting layer.
Use cases: teachers reusing exam papers, students practicing with past papers, tutoring centers saving printing costs.
Processing requires cloud AI inference; files are encrypted in transit and deleted from servers immediately after processing.
Privacy Protection
WebAssembly local processing means: files never leave your device, no network transfer, no server storage. Basic features work even offline.

FAQ
How does AI Document Restore identify handwriting?
Allin PDF uses multimodal AI (Gemini, GPT-4o, Claude) to analyze scanned documents. The AI visually distinguishes between printed text (uniform, consistent strokes) and handwritten content (variable, organic strokes) using its vision capabilities, then regenerates only the printed elements.
What types of documents work best with AI Document Restore?
Best results: exam papers, worksheets, printed forms with handwritten entries, and typed documents with handwritten annotations. The tool works best when printed text is clearly distinct from handwriting (e.g., typed exam questions with handwritten answers in pencil or pen).
How many pages can I restore per day?
Free users get 1 trial per account (lifetime). Pro subscribers ($9.99/month or $59.99/year) can restore up to 50 pages per day. Each page takes approximately 5-10 seconds to process.
Is AI Document Restore processed locally or in the cloud?
Cloud processing. The document is sent to Gemini/GPT-4o/Claude API for AI analysis, which requires internet connectivity. Files are encrypted during transfer and not stored after processing. This is the only tool in Allin PDF that requires cloud processing — all other tools work locally.
