Prompt haKCer is a Chrome add-on designed to enhance your interactions with AI models by optimizing the prompts you use. This tool focuses on improving clarity, security, and efficiency in AI communications. It features automatic data leak protection that redacts sensitive information such as credit card numbers, emails, and API keys before they leave your browser, ensuring that your data remains secure. Additionally, it helps reduce prompt size by up to 70%, which can lead to significant savings on token costs when making API calls.

In addition to its security and cost-saving measures, Prompt haKCer boosts AI performance by ensuring that models receive clear and concise instructions, leading to sharper and more accurate responses. Users can optimize their workflow with a single click or hotkey, eliminating the need for manual edits. The add-on also supports custom and crowdsourced rulesets, allowing users to maintain local rules or benefit from regularly updated guidelines sourced from a repository. Furthermore, it offers data control features that enable users to export their activity for research and analysis.
