Writing prompts shouldn't be this hard

The ugly truth about AI prompts today...

Endless Trial & Error

You keep rewriting prompts hoping for better results — but AI tools still don’t get what you mean. It's draining your focus and momentum.

Wasting AI potential

You’re paying for top-tier AI, but every vague prompt is a missed opportunity. It’s like owning a Ferrari and never leaving first gear.

Paying for Misses

Every bad output costs time, energy, and money — especially when using paid models.

Not made for builders

Most tools are made for SEO bros and researchers — not indie hackers coding with AI.

Stop begging AI to understand you. Start commanding it.

Improve your prompts and unlock better AI output

Tired of vague outputs? Paste your prompt, let our AI refactor it using expert-level techniques, and get better results from every agent.

Prompt optimization

Rewrites prompts using industry best practices.

Tailored for AI coding agents like Cursor, Claude, Replit, Bolt.new.

Removes vagueness and improves clarity and intent.

Time saved: 2 hours

Prompt like a pro, not like a gambler.

Prompts without Prompster

Spend hours tweaking prompts manually

Vague outputs from AI agents

FAQ

Frequently Asked Questions

You get instant access to a powerful prompt optimization dashboard. Simply enter your prompt, and it will return an enhanced version using industry best practices - ready to use in AI coding tools like Cursor or Claude. All plans include: unlimited optimizations, context-specific improvements (frontend/backend/debugging), rapid processing, full history tracking, and future updates. Start with 5 free optimizations to experience the difference.

Prompster enhances your prompts using advanced AI trained on proven prompt engineering techniques specifically optimized for coding workflows. Our system analyzes your input to remove ambiguity, inject relevant technical context (like specifying frameworks or debugging scenarios), and restructures queries using patterns that consistently deliver better results with AI coding assistants. The optimized output maintains your original intent while applying professional-grade improvements - whether you need clearer instructions for Claude, more precise debugging with Cursor, or efficient API design prompts.

We currently use GPT-4o-mini as our core optimization engine, specifically fine-tuned for prompt engineering tasks. This allows us to deliver fast, cost-effective optimizations while maintaining high-quality results. As we scale, we arere actively testing more advanced models to further improve output quality

Absolutely. Every prompt optimized through Prompster is specifically designed for seamless use with AI coding tools like Cursor, Claude, Bolt, Replit, and more.

Both plans give you full access to all Prompster features - unlimited optimizations, context-aware refinements, and prompt history. The only difference is billing: Flex is $9/month for maximum flexibility, while Smart Annual ($90/year) saves you 17% with 2 months free. It is not about features, but how you prefer to invest in your AI workflow.

We offer a risk-free way to test Prompster with 5 free optimizations before paying. If you purchase a plan without using your free optimizations, we provide full refunds within 7 days as long as you have not exceeded 5 total prompt optimizations. Once you pass this threshold, we consider the tool actively adopted and do not offer refunds - but you can cancel anytime.

You do not need to pay to try Prompster - your 5 free optimizations give you full access to test all features risk-free. The paid plans are only necessary if you need unlimited optimizations for ongoing projects.

We securely store your prompts to maintain your optimization history - a core feature you can access anytime. While we do not currently use this data for AI training, our Terms of Service allow for potential future use to improve Prompsters performance. If you wouldd like to opt out of any future training usage, please email me at leonelfr212@gmail.com and I will flag your account accordingly.

During our Beta phase, you can guide optimizations by selecting specific contexts (like frontend, backend, or debugging) - but full rule customization is not available yet. We are actively testing advanced customization features based on user feedback from this initial release. Want to prioritize a particular optimization style? Email me at leonelfr212@gmail.com with your workflow needs!

That is exactly why we offer 5 free optimizations - so you can test the tool risk-free and see the difference firsthand. If your prompts do not show noticeable improvement during your free trial, you will know Prompster is not right for your needs before spending anything.

Not at the moment. We currently focus on individual plans (Flex and Smart Annual).
