| Description | MaskMyPrompt is a tool that anonymizes your prompts before sending them to ChatGPT. It ensures that all your prompt data stays private and never gets saved or sent to any server. The tool also highlights names and masks them effectively to maintain the confidentiality of the information you are sharing. Programmed by Mike Ushakov and ChatGPT, MaskMyPrompt integrates with Transformers.js library, offering seamless operations. If you encounter any bugs or have feature requests, you can reach out via email or Twitter. | The HeroPost Prompt Generator allows users to create dynamic prompts for ChatGPT and Midjourney, which can be saved and shared in an unlimited number of lists and spaces.
