PromptPerfect shut down on September 1, 2026
If you are looking for another way to improve a text prompt, this page is about that job. It is not a history of PromptPerfect, and it does not guess why the product closed.
A good fit when the job is the prompt
PromptShield can fit if what you wanted from PromptPerfect was a clearer text prompt before you sent it.
- Improve a text prompt before you send it
- Make a vague request specific enough to answer
- Add the missing detail that would change the reply
- Stay in the AI chat instead of copying the prompt into another tool
A different workflow
Your prompt does not need more words. It needs the right information. PromptShield is meant to keep the job you already have in mind and make that request clearer.
1
Write what you mean
Type the prompt in the chat you already use.
2
Run Quick Check
Open PromptShield beside the composer.
3
Review the improvement
Read a clearer version of the same request.
4
Use the version you prefer
Use this version replaces the draft only if you choose it.
5
Send it yourself
PromptShield never sends the message.
- ChatGPT
- Claude
- Gemini
- Perplexity
- Grok
- DeepSeek
- Meta AI
Meta AI means the Meta AI web chat, not Instagram, Facebook, Messenger, or WhatsApp. Microsoft Copilot is not supported. There is no mobile browser extension.
What you wrote, and a clearer version
This is a written example, not a live Quick Check. The clearer version names the job, who it is for, and the shape of a useful answer. It does not invent facts the original prompt left out.
What you wrote
write a blog post about remote work
A clearer version
Write a blog post about remote work that a reader could actually use. Compare what changes for someone managing a remote team with what changes for someone who is newly remote, and include one concrete weekly routine instead of a list of slogans. Keep it about the length of a short article, skip clichés about pajamas and hustle, and end with one change a reader could try next week. If the right advice depends on team size or the reader’s role, say so instead of inventing a company.
What changed
- Asks for a usable routine instead of a generic essay.
- Covers two real readers without assigning you one fake audience.
- Sets length and bans the clichés that make these posts sound the same.
Example of the kind of improvement PromptShield is designed to make. Written ahead of time. PromptShield did not generate this just now, and a real Quick Check will not always use these words.
