DeepSeek
DeepSeek prompt optimizer
DeepSeek is often used for coding and step-by-step reasoning. Those tasks go better when the prompt includes the environment, the failure, and what a good answer looks like.
For code, include the failure
Paste the relevant function, the input, the result you got, and the result you expected. Ask for the cause before a rewrite, and say if you want the smallest possible change.
PromptShield does not run your code or see your repository. It only helps you improve the prompt you are about to send.
Review before you send
In Chrome, PromptShield’s Quick Check works in DeepSeek’s web chat the same way it works in the other supported chats. You can ignore the suggestion. Optimization History stores successful checks according to the product rules, and context-derived results are handled separately when conversation context is on.
Before and after
A written comparison, not a live optimization. Use it to see what specificity changes.
Rough prompt
my code is broken fix it
Clearer prompt
I will paste the function, the input, the actual result, and the expected result. Explain the cause before changing as little as possible.
DeepSeek still needs the failure. PromptShield does not run the code.
Prompt checklist
A useful check before you send. It is not a scientific requirement, and a short prompt can still be enough when the chat already has the missing pieces.

No. The supported chats are ChatGPT, Claude, Gemini, Perplexity, Grok, DeepSeek, and Meta AI’s web chat.
Quick Check sends the prompt to PromptShield over HTTPS so it can return feedback and an improved version. PromptShield does not send that prompt to the AI chat for you. You review the result and decide whether to use it. Optional conversation context stays off until you turn it on.
PromptShield is a Chrome extension for desktop Chrome. It works inside ChatGPT, Claude, Gemini, Perplexity, Grok, DeepSeek, and Meta AI’s web chat. It is not a mobile app, and Meta AI support is not a Facebook or Instagram integration.
