PromptPerfect shuts down in September 2026. Prompeteer.ai is a direct alternative with 16-dimension Prompt Score, support for 140+ AI platforms, contextual prompt generation, and a Chrome extension. Existing PromptPerfect users can move their prompts across, keep the auto-tuning workflow they relied on, and gain platform-specific optimisation plus a library that learns their style over time.
PromptPerfect optimized prompts. Prompeteer engineers them, with 16-dimension quality scoring, platform-specific optimization, and a contextual AI platform that reduces hallucinations before they start.
Prompeteer doesn't just replace PromptPerfect; it leapfrogs it with enterprise-grade prompt engineering capabilities no other tool offers.
Not Just a Replacement. A Generational Leap.
PromptPerfect auto-tuned prompts. Prompeteer understands them, scoring quality across 16 dimensions, optimizing for specific platforms, and learning your style over time.
- Contextual AI Platform — Evidence-based prompt generation grounded in published techniques and ICLR 2025 findings. Constructs prompts that reduce hallucinations at the structural level, not a black-box auto-tune.
- Prompt Score — 16-dimensional quality scoring: clarity, specificity, context depth, anti-hallucination markers, reasoning structure, and 11 more. Know exactly what's strong and what needs work.
- Platform-Specific Optimization — Platform-specific optimization for ChatGPT, Claude, Gemini, Perplexity, DALL-E, Midjourney, Runway, Suno, and every other platform in the directory. Not generic: tuned to each platform's capabilities.
- Chrome Extension — Real-time Prompt Score directly in ChatGPT, Claude, Gemini, Perplexity, and Grok. Optimize without leaving your AI tool. Auto-save everything to your Drive.
- Arena Mode — Compare Claude, GPT-4o, and Gemini side-by-side on the same prompt, each response scored by Prompt Score. Data-driven model selection, not gut feel.
- Enterprise Teams — Shared prompt libraries, team workspaces, role-based access, usage analytics, SSO, and white-label deployment. Built for the enterprise scale PromptPerfect never reached.
Why is PromptPerfect shutting down?
Elastic acquired Jina AI (PromptPerfect's parent company) in October 2025 for its embedding models and neural search technology. PromptPerfect doesn't fit Elastic's enterprise search roadmap and is being sunset. New signups close June 2026; full shutdown September 1, 2026; data deletion October 1, 2026.

Common Questions
Everything PromptPerfect users need to know about switching.
When exactly is PromptPerfect shutting down?
Elastic acquired Jina AI (PromptPerfect's parent company) in October 2025. PromptPerfect stops accepting new signups in June 2026, goes fully offline September 1, 2026, and permanently deletes all user data on October 1, 2026.
Can I import my PromptPerfect prompts?
PromptPerfect doesn't offer data export. You can copy your saved prompts and paste them into your Drive on Prompeteer. Our platform auto-scores them with Prompt Score and suggests optimizations. We recommend migrating before the October 2026 data deletion deadline.
How is Prompt Score different from PromptPerfect's optimization?
PromptPerfect offered black-box auto-tuning: it "improved" your prompt without explaining how. Prompt Score evaluates across 16 specific dimensions (clarity, specificity, context, anti-hallucination, and more) so you understand exactly what's strong and what needs improvement. It's the difference between a spell-checker and a writing coach.
Is Prompeteer free?
Yes. Free tier includes 10 prompts per month, Chrome extension access, and Drive storage. Pro offers unlimited prompts, Arena Mode, priority generation, and advanced analytics. Enterprise plans include team features, SSO, and white-label deployment.
Does Prompeteer support image, video, and audio prompts?
Yes. Prompeteer generates optimized prompts across all 5 modalities (text, image, video, audio, and code) for platforms including DALL-E, Midjourney, Stable Diffusion, Runway, Pika, and Suno. PromptPerfect only supported text and basic image prompts.
