The research

What if you’ve been asking it wrong?

Three published studies showing the same AI gives wildly different answers based purely on how you write the prompt. Prompten writes it the right way for you.

Make LLMs 3 times more accurate.

Backed by Google Research

Researchers gave Google’s most powerful AI a pile of grade-school math problems. With a normal prompt, it got 17.9% correct — basically a coin flip. Adding the phrase “Let’s think step by step” before each problem? 56.9% correct. Same model, same questions, three times more right answers. Prompten applies that kind of tweak automatically, every time.

Wei et al., Google Research, 2022

Chain-of-Thought Prompting Elicits Reasoning

You’re not maximizing your AI capabilities.

Researchers measured it

Scientists shuffled the same four examples in a prompt and watched answer quality swing from random guessing all the way to expert-level. The AI isn’t the bottleneck — the way you ask is. Most people typing prompts have no idea they’re leaving most of their AI’s capability on the floor. Prompten doesn’t.

It’s not the AI. It’s how you ask.

Format is a hidden setting

Bullets vs numbered lists, Markdown vs JSON, “Question:” vs “Q:” — researchers showed each of these tiny tweaks moves AI accuracy by tens of points. The model reads format as a signal for what kind of answer you want, even when you didn’t mean to send one. Prompten picks the right format for you.

Half the answer is in the prompt. Prompten handles the prompt so you can stop guessing what works.

Before

write a blog post about productivity

What you typed

Enhance

After

You are a productivity writer with 10+ years of experience writing for busy knowledge workers. Write a 1,200-word blog post about three evidence-backed productivity techniques that mid-career professionals consistently overlook (e.g., timeboxing, the 2-minute rule, deep-work blocks). For each technique: (1) explain how it works, (2) cite the research or expert who popularised it, (3) give one concrete 5-minute example of applying it today. Tone: conversational, specific, no jargon. Open with a hook drawn from a real workplace scenario, not a definition. Close with a single clear call-to-action inviting the reader to try one technique this week and reply with the result.

FAQ

Common questions

Does Prompten store my prompts?

We process your prompts to enhance them and return the result. Prompt content is not logged, stored, or used to train any model. See our Privacy Policy for the full data flow.

Which AI tools does it work with?

The Chrome extension injects an enhance button directly into ChatGPT, Claude, Gemini, and Grok. You can also paste enhanced prompts into Copilot or anywhere else. More native integrations are on the roadmap.

Do I need an OpenAI API key?

No. Prompten runs its own backend — you just sign up, install the extension, and click the enhance button.

What's the difference between Enhance and Expand?

Enhance polishes and sharpens your prompt without padding it. Expand fully restructures it into a thorough, detailed instruction with explicit context, constraints, and format guidance.

What's the science behind the rewrite?

Prompten applies the techniques the AI labs themselves publish — assigning an expert role, adding step-by-step structure, specifying audience and format, supplying explicit constraints. Published research (linked in the Research section above) shows these techniques can move accuracy by tens of points on standard benchmarks.
