PDF Robot - our flagship PDF editor

PDF Robot is a feature-rich offline PDF editor for Windows 10 and 11. It handles everything most people need from a PDF tool: editing text, adding signatures, merging and splitting files, redacting sensitive content, filling forms, and exporting to Word or Excel. It also includes a built-in AI assistant powered by OpenAI, Anthropic, Gemini, or local Ollama models. Try it free at our Free Stuff page - no credit card, no time limit on basic features.

Practical coding ebooks

Our Books section has a growing series of step-by-step guides on building real-world applications with Claude AI and VSCode. Topics include mobile apps, web apps, Syspro ERP integrations, and Python trading bots. Each book is $5 and aimed at people who want working code, not theory.

Free online games and Android apps

On the Apps and Games page you will find browser-based games like FlappyDisk that you can play instantly, and Android apps we publish under the PhantomBinary name.
