What Happened to PromptPerfect?
PromptPerfect, the prompt optimization tool built by Jina AI, is shutting down. In early 2026 Elastic announced the acquisition of Jina AI, the company behind PromptPerfect, to bring Jina's embedding and neural search technology into the Elastic stack.
As part of the acquisition, Elastic confirmed that PromptPerfect would be sunset. The tool stops accepting new signups in June 2026 and goes offline permanently on September 1, 2026. Existing users have until that date to export their data.
PromptPerfect was one of the earliest dedicated prompt optimization tools, letting users refine prompts for ChatGPT, Claude, Gemini, and other models with automated suggestions. Its shutdown leaves a gap for users who relied on it for daily prompt work.
Why PromptPerfect Is Shutting Down
The short version: Elastic bought Jina AI for its embedding and search technology, not for its consumer prompt tool.
Jina AI built two things: a powerful embedding/reranking engine used by enterprises for semantic search, and PromptPerfect, a consumer-facing prompt optimizer. Elastic wanted the first part. The embedding models and neural search capabilities fit directly into Elastic's search platform.
PromptPerfect doesn't fit that vision. It's a standalone consumer tool that competes for engineering resources without contributing to Elastic's core search business. Rather than maintain a product outside their focus, Elastic chose to wind it down.
This isn't unusual. Acquisitions regularly result in non-core products getting cut. If you relied on PromptPerfect, the good news is that the alternative options in 2026 are better than what was available when PromptPerfect launched.

How to Migrate from PromptPerfect
Moving your workflow from PromptPerfect to Prompt Builder takes about 15 minutes. Here's the step-by-step process.
Export Your PromptPerfect Data
Log into PromptPerfect, go to Settings > Export Data, and download your saved prompts. Do this before September 1, 2026. Your export will include prompt text, optimization history, and any saved configurations.
Sign Up for Prompt Builder
Create a free account at promptbuilder.cc. No credit card required. The free tier includes 25 AI assistant requests per month, which is enough to get started.
Recreate Your Key Prompts
Use the Prompt Generator to rebuild your most-used prompts. Paste your exported prompt text as a starting point, then use the optimizer to improve it. Most users find Prompt Builder's output is better than what PromptPerfect produced.
Save to Your Prompt Library
Save each recreated prompt to your library with tags and categories. Unlike PromptPerfect's basic save/load, Prompt Builder's library supports search, filtering, and organization so your prompts stay accessible as your collection grows.
Other PromptPerfect Alternatives
Prompt Builder is our recommendation, but here are other options worth considering depending on your workflow.
PromptLayer
PromptLayer is built for developers and teams that need prompt versioning, A/B testing, and production monitoring. It's more of an engineering tool than a consumer prompt optimizer. If you're managing prompts in a production app, PromptLayer is worth a look. The free tier supports up to 1,000 requests per month.
Model Provider Consoles
If you mostly work with one model, the provider's own playground may be enough. OpenAI Playground, Anthropic Console, and Google AI Studio all let you test and tweak prompts directly. The downside: no cross-model support and limited prompt management features.
LangSmith
LangSmith (by LangChain) is a developer-focused platform for tracing, evaluating, and monitoring LLM applications. It's not a direct PromptPerfect replacement for prompt optimization, but if you're building LLM-powered apps and need observability, it's a strong option. Free tier available for small projects.

Prompt Builder covers everything PromptPerfect did and more. Generate, optimize, and manage prompts for every major model, all in one place.
25 free assistant requests/month. No credit card required.
PromptPerfect Alternative: Frequently Asked Questions
Common questions about PromptPerfect's shutdown and finding a replacement.
Elastic acquired Jina AI (PromptPerfect's parent company) to integrate Jina's embedding and search technology into the Elastic platform. PromptPerfect, a consumer prompt optimization tool, doesn't fit Elastic's enterprise search focus, so they're sunsetting it on September 1, 2026.
PromptPerfect stops accepting new signups in June 2026 and shuts down completely on September 1, 2026. All user data will be deleted 30 days after shutdown unless exported before then.
Yes. PromptPerfect allows bulk export of your saved prompts through Settings > Export Data. Do this before September 1, 2026 to avoid losing your work.
Prompt Builder is the best free alternative. It offers 25 free AI assistant requests per month, a prompt generator, optimizer, and template library with no credit card required. Unlike PromptPerfect, it supports all major models including ChatGPT, Claude, Gemini, and Grok.
Yes. Prompt Builder includes a dedicated prompt optimizer that rewrites and improves your prompts for better AI output. It also offers a prompt generator for creating prompts from scratch and a template library with hundreds of ready-to-use prompts.
Export your prompts from PromptPerfect (Settings > Export Data), sign up for a free Prompt Builder account, then recreate your most-used prompts using the prompt generator or optimizer. Save them to your library for quick reuse. The whole process takes about 15 minutes for most users.
