PromptPerfect just posted their shutdown notice. No new signups as of June. Full shutdown September 1. Data deleted October 1. Elastic acquired Jina AI last fall and apparently didn’t want the product.
If you’ve been using it to test and refine prompts, you need a new home.
The replacement that actually caught attention: Prompeteer.ai. And here’s what makes it different from every other prompt optimizer out there.
It doesn’t just score your prompt. It scores the output too.
That’s the twist. Most tools tell you “your prompt is too vague” and leave you guessing what to fix. Prompeteer runs a 16-dimension analysis on both the input and the AI’s actual response. The output feedback is where the real signal lives.
Here’s how to put it to work 🔧
- Paste your prompt into Prompeteer
- Run it through the 16-dimension Prompt Score system
- Read the output score, not just the prompt score — that’s where you find out what’s actually breaking 🎯
- Revise based on what the output analysis tells you, not just the prompt grading
- Save your winning prompts to PromptDrive, their visual library so you’re not rebuilding from zero every time
Pro tip: Prompeteer works across 140+ AI platforms. Run the same prompt through multiple models and compare output scores side by side. That’s a faster feedback loop than any manual testing.
Pro tip: Export everything from PromptPerfect before October 1. Data deletion is not a soft deadline.
September is coming faster than you think. Start the migration now 🚀
PromptPerfect is setting Sept 2026. What are you migrating to?
