What is Ask PDF?

Ask PDF is an AI-powered browser extension that transforms your documents into smart, searchable vector knowledge bases.

Key Features: • Multi-Doc Cross-Analysis: Upload multiple PDFs simultaneously and cross-reference insights across your entire workspace. • Session Auto-Recovery: Built-in IndexedDB state manager ensures your processing progress is saved—resume interrupted uploads seamlessly anytime. • Custom Knowledge Base Tags: Easily separate documents into isolated project workspaces (e.g., Legal_Contract, Q3_Financials, Scholarly_Research). • Specialized AI Copilots: Switch between domain-specific agent scenes like Legal, Financial, Scholarly, or General Assistant. • High-Value Pay-As-You-Go ($1 for 400 credits): No monthly subscriptions—pay $1 for 1.2M characters of total processing power.
