If you are a developer or a company that prioritizes privacy and has the technical expertise to set up a local deployment, choose private-gpt. Its 100% privacy with local deployment ensures that your interactions with documents remain confidential, making it ideal for sensitive applications. However, if you lack technical knowledge and prefer a more user-friendly solution, avoid this tool.
On the other hand, if you are part of a business that requires robust PDF processing and can handle the costs associated with a paid model, Stirling-PDF is the better choice. It supports high-volume processing and is designed for secure environments. Keep in mind, though, that if you need strong mobile functionality or want a completely free tool, Stirling-PDF may not meet your needs.
