What is Chat Copilot
Refine your prompts with on-device AI before sending them to ChatGPT, Claude, Gemini, Grok, or Microsoft Copilot. How often have you had to rewrite your prompt because ChatGPT assumed you meant something else? The frustration of this back and forth increases the barrier to wider adoption of AI for everyday activities. Chat Copilot was built for that specific usecase in mind. The extension serves as your copilot for LLMs. It allows you to improve the prompts you write to ChatGPT, Gemini, Claude, Microsoft Copilot and Grok!
Chat Copilot improves your prompt based on the LLM you're using. This enables you to tailor your prompt to the LLM you're using. It also gives you a quality score for your prompts based on 5 metrics: clarity, specificity, structure, completeness and actionability.
The extension uses only local models and keeps all analytics local so you can see your improvement over time. Please share any feedback and suggestions for improvement and new features with [email protected].
