On the first try.
Turn rough ideas into clear, optimized prompts built for the AI you use. Spend less time rewriting prompts, reduce unnecessary back-and-forth, and get closer to the result you want.
Watch the 38-second tour- Better prompts
- Fewer retries
- Model-specific optimization
- No prompt expertise required
Scoring is free for everyone. Optimizing needs a free account — no card.
From rough idea to AI-ready prompt
ExampleBefore
write a blog post about remote work
After (Optimized)
Clearer instructions. More context. Fewer reasons for AI to guess.
38-second tour
See it work, start to finish.
A rough prompt goes in. Smart Clarify asks what's missing, the optimizer rewrites it for the model you use, and the scorer shows the change — 19 to 84, on the same deterministic scorer — before you copy it out.
Why you get better results
- 1
Understand what's missing
We score your prompt before changing anything, so you can see what is holding it back.
- 2
Fill the important gaps
Smart Clarify asks only the questions needed to give AI the context it's missing.
- 3
Optimize for your AI
The final prompt is structured for ChatGPT, Claude, Gemini or the model you're actually using.
One better prompt. Less trial and error.
Everything you need to get better AI results
Prompt Optimizer
Turn rough ideas into AI-ready instructions.
Prompt Score
Know what's weakening your prompt before you send it.
Smart Clarify
Fill missing context without guessing what to add.
Model-specific output
Use the right prompt structure for the AI you're using.

Don't just trust the rewrite. Measure it.
Better AI Prompts scores your prompt before and after optimization using the same deterministic scoring system.
Deterministic
The same prompt always gets the same score. No model opinion involved.
The model never grades its own work
Before and after run through the same scoring function, so improvement is measured consistently.
“What changed” is computed
Changes come from comparing the two prompts, not from asking the model what it did.

Built to earn your trust
The scoring rules are published
Seven dimensions with stated weights. See exactly how your prompt is evaluated.
Your prompt never goes into a URL
“Try in ChatGPT” copies your prompt before opening the AI tool.
We never invent facts about your product
Missing details become visible [placeholders] rather than confident guesses.
Analytics record what happened, not what you wrote
Event names and counts only. Prompt text is stripped before analytics are sent.
Frequently asked questions
Why not just ask ChatGPT or Claude to improve my prompt?
You can, and it will happily tell you the result is better. Nothing measures whether it is. Here both versions go through the same scorer, the changes are computed by comparing the two prompts, and the rewrite follows the conventions of the model you actually use.
How does Better AI Prompts improve my AI results?
It scores what you wrote across seven dimensions, asks about anything essential that is missing, and rewrites the prompt in the structure your target model responds to. A clearer, more complete prompt gives the model less to guess about.
What is Prompt Score?
A 0–100 rating built from seven weighted dimensions: clarity, context, specificity, constraints, output format, examples and model fit. It is deterministic, so the same prompt always scores the same, and it runs in your browser without a model call.
Does Better AI Prompts guarantee better AI results?
No, and nothing could. Better AI Prompts improves the structure and completeness of your prompt, which is the part we can measure and show you. What the AI does with it is still the model's behaviour, and that varies by task, model and version.
Does Better AI Prompts save tokens?
Better-structured prompts can reduce unnecessary retries and back-and-forth, which may reduce token usage. An optimized prompt is usually longer than what you started with, so actual usage depends on the task, the model and the output. We do not claim a saving we cannot measure for you.
Which AI models does Better AI Prompts support?
Prompts are optimized for ChatGPT, Claude, Gemini and Claude Code with dedicated structures, and for Cursor, Perplexity, Grok, Midjourney, v0, Replit and Bolt through the general adapter. Auto picks the best fit for your task if you'd rather not choose.
Are my prompts private?
Optimization sends your prompt to our AI provider and nowhere else, and we do not train models on it. Signed out, scoring runs in your browser and the prompt never leaves it. Signed in, an optimized prompt appears in your own history, which you can clear, and saved prompts stay in your library until you delete them. Uploaded images are read once and never stored. Analytics never receive prompt text.
Is Better AI Prompts free?
Yes to start: 20 optimizations a month on a free account, and unlimited prompt scoring with no account at all. Paid plans are published for transparency but are not on sale yet.
