# PDF Ghost > PDF Ghost lets you fingerprint PDFs per-recipient and detect leaks. Upload a document, add recipients, and the platform embeds a unique invisible fingerprint in each copy. If a copy appears somewhere it shouldn't, run a leak check to identify exactly which recipient shared it. Billing is token-based with monthly quotas per plan and purchasable top-up packs. ## Key Concepts PDF Ghost is organized around **organizations** — teams share a token quota and manage jobs together. A **job** is one fingerprinting run for a single document. Each job has **recipients**: the individuals who will each receive a uniquely fingerprinted copy. Processing a job consumes **tokens** from the organization's balance. Job lifecycle: **Draft → Pending → In Progress → Completed / Failed**. Jobs can be edited while in Draft. Once submitted, processing is automatic. **Leak detection** works by uploading a suspected leaked copy. PDF Ghost reads the embedded fingerprint and tells you which recipient's copy it matches. **Plans and token quotas** (monthly, per organization): Free — 50 tokens, Starter — 500 tokens, Pro — 5,000 tokens, Team — 20,000 tokens. Additional token packs can be purchased at any time: 100 tokens ($9), 500 tokens ($35), 2,000 tokens ($99), 5,000 tokens ($199). Unused monthly tokens do not roll over; purchased pack tokens do not expire. ## Docs - [Getting Started](https://pdfghost.com/docs/getting-started/overview): Account creation, organization setup, and first-run walkthrough. - [First Job Guide](https://pdfghost.com/docs/getting-started/first-job): Step-by-step instructions for creating and processing your first fingerprinting job. - [Job Management](https://pdfghost.com/docs/core-features/job-management): Job lifecycle states, how to create, edit, submit, and monitor jobs. - [Leak Detection](https://pdfghost.com/docs/core-features/leak-detection): How to run a leak check, upload a suspected file, and interpret which recipient is the source. - [Tokens & Billing](https://pdfghost.com/docs/core-features/tokens): Token consumption rules, monthly quota resets, purchasing token packs, and upgrading plans. - [Dashboard](https://pdfghost.com/docs/user-guides/dashboard): Reading job stats, token balance, and organization activity at a glance. - [Settings](https://pdfghost.com/docs/user-guides/settings): Account profile, organization management, billing portal, and subscription changes. - [Security Best Practices](https://pdfghost.com/docs/best-practices/security): Recommendations for secure document handling and access control. - [FAQ](https://pdfghost.com/docs/faq/common-questions): Answers to common questions about fingerprinting accuracy, billing, and workflow. - [Troubleshooting](https://pdfghost.com/docs/faq/troubleshooting): Fixes for common issues — upload errors, processing failures, and token deduction problems. ## Optional - [Pricing](https://pdfghost.com/pricing): Plan comparison table and token pack pricing details. - [Blog](https://pdfghost.com/blog): Use-case articles, product updates, and document security guides. - [Changelog](https://pdfghost.com/changelog): Full history of releases and feature changes. - [Privacy Policy](https://pdfghost.com/legal/privacy-policy): How user data and uploaded documents are stored and handled. - [Terms of Service](https://pdfghost.com/legal/terms): Usage conditions and service agreement.
