PromptPerfect Alternative
PromptPerfect sunsets September 1, 2026. Here's where to take your prompt-engineering workflow next.
The PromptPerfect sunset, in plain terms
Elastic acquired Jina AI in early 2026. PromptPerfect (a consumer prompt optimizer) does not fit Elastic's enterprise-search focus, so the product is being wound down.
June 2026: new sign-ups close. September 1, 2026: the service goes permanently offline. 30 days later: all user data is deleted unless exported beforehand via Settings → Export Data.
If you are an active PromptPerfect user, the practical deadline is roughly August 2026: late enough to keep using the tool, early enough to export safely and migrate before the lights go out.
What FreeAI.DevTools offers instead
We have two tools that cover the prompt-engineering workflow PromptPerfect users are migrating from. Both are free, sign-up-free, and run 100% in your browser.

Two different philosophies
PromptPerfect was an opaque rewriter: paste a prompt, click optimize, get back a longer prompt that often performed better but with no explanation of why. The optimization model was a black box.
Our tools take the opposite approach. The Prompt Generator and System Prompt Builder ask you to compose your prompt in named pieces (role, task, constraints, output format) and then assemble them. You can see exactly what each piece contributes, which means you can iterate, version, and reuse them.
We chose this approach for three reasons: transparency (you can read every word of the final prompt and know where it came from), learnability (composing prompts is itself the skill, and a builder teaches it), and reproducibility (the same inputs always produce the same prompt, so your workflow is portable across model upgrades).
Migrating your prompts
Step 1: Export from PromptPerfect. Open Settings → Export Data and download your saved prompts. Do this before August 2026 to keep a comfortable buffer ahead of the September 1 cutoff and the 30-day deletion window that follows.
Step 2: Decompose into pieces. Read each exported prompt and identify the role definition, the task, any constraints or rules, and the desired output format. PromptPerfect bundled these together; our builders keep them separate.
Step 3: Paste into the right tool. Use the Prompt Generator for one-off task prompts (creative writing, analysis, etc.) and the System Prompt Builder for reusable system messages that ship with API calls.
We do not yet have an automated importer. If there is enough demand, we will add one. Let us know.
Frequently asked
- Is FreeAI.DevTools really free?
- Yes. There is no sign-up, no paywall, and no usage limits. We are funded by display ads on tool pages: no paid tier, no premium features, no upsells.
- Can I import my saved PromptPerfect prompts?
- Not automatically. Export your prompts from PromptPerfect via Settings → Export Data, then paste them into our Prompt Generator or System Prompt Builder. We may add an importer later if there is demand.
- Does FreeAI.DevTools auto-optimize my prompt like PromptPerfect did?
- We take a different approach. PromptPerfect was an opaque rewriter: paste in, get an optimized prompt out. Our tools are structured builders, where you compose role, task, constraints, and output format yourself. We chose transparency, learnability, and reproducibility over a black-box rewriter.
- Which models does it support?
- Any LLM. Our output is plain text, so it works with ChatGPT, Claude, Gemini, Mistral, Llama, DeepSeek, Grok, and any local model you can paste a prompt into.
- Will my prompts leave my browser?
- No. All processing is 100% client-side. We never see, store, or transmit your prompt content. There is no server involved in tool execution.
- What happens to my PromptPerfect data?
- PromptPerfect stops accepting new sign-ups in June 2026 and goes permanently offline on September 1, 2026. All user data is deleted 30 days after shutdown. Export your prompts via Settings → Export Data before August 2026 to be safe.
- How is FreeAI.DevTools funded?
- Display ads on tool pages. No paid tier, no premium features, no upsells. The tools and their source data stay free.
