The AI prompt enhancer for every AI tool

Turn a rough sentence into a structured, high-quality prompt in one click. Works inside ChatGPT, Claude, and Gemini via Chrome extension — and inside Claude Code, Cursor, and Antigravity via a macOS global hotkey.

Free to try. No account required for the demo. One account covers both products.

Raw prompt

help me make this landing page copy more persuasive

Enhanced prompt

You are a senior conversion copywriter with B2B SaaS experience. Rewrite the landing page copy I paste below to be more persuasive to a technical buyer evaluating PromptAI. Keep it under 120 words per section. Tone: confident, not salesy. Output format: the rewritten copy only, preserving the original section structure. Constraints: no hype language, no em-dashes.

What is an AI prompt enhancer?

An AI prompt enhancer is a tool that rewrites your plain-language input into a structured prompt before it reaches the AI. Instead of typing “summarize this article” and hoping the model picks the right format, the enhancer adds the pieces professional prompts include — role, context, step-by-step instructions, constraints, and output format.

PromptAI is the enhancer that meets you wherever you're already working. In the browser, it's a Chrome extension that drops a button into ChatGPT, Claude, and Gemini. On macOS, it's a desktop app that adds a global hotkey so you can enhance prompts inside Claude Code, Cursor, Antigravity, and any native app.

The goal isn't to make prompts longer. It's to make them unambiguous. A well-enhanced prompt gives the model a clear goal, a clear format, and a clear set of constraints — the difference between responses you have to rewrite and responses you can ship.

Why it matters

The quality gap is the prompt, not the model

People who get great AI responses and people who get mediocre ones are usually using the same model. The gap is almost entirely in how they structure the ask. Four patterns account for most of the difference.

No role assigned

“Write a product description” gives the model nothing to anchor to. “You are a senior e-commerce copywriter for premium outdoor brands” changes the output substantially — role framing activates the model's knowledge around that persona.

Ambiguous goal

“Summarize this” has three reasonable interpretations at minimum (bullets, paragraph, executive abstract). The model picks one — often not the one you wanted — and you rewrite.

No output format

The single change that produces the biggest quality jump is specifying format: “Output as a markdown table with three columns.” Most prompts skip this and the model freestyles in prose.

No constraints

Without guardrails (“under 200 words”, “avoid jargon”, “no marketing language”), the model defaults to safe, generic output that reads like every other AI response.

How it works

Five things the enhancer adds to every prompt

Role definition

A specific persona — “senior tax advisor”, “Python tutor for beginners”, “senior Go engineer reviewing a PR” — that primes the model to draw on relevant patterns. Alone, this measurably shifts tone and accuracy.

Context framing

The who, what, and why behind the request. Who is the answer for? What's already been tried? What's the actual goal beyond the surface task? Missing context is the most common reason prompts underperform.

Structured instructions

The ask broken into ordered steps or numbered requirements, rather than a run-on sentence. Ordered instructions get executed more reliably — the model doesn't have to infer which parts are instructions and which are context.

Explicit constraints

Length limits, forbidden words, required tone, audience reading level. Constraints are what stop the model from producing the safe, generic version of an answer — they force specificity.

Output format

Exactly how the answer should be shaped — markdown table, JSON, numbered list with per-item character limits, four H3 sections with code blocks. The highest-leverage change you can make to any prompt.

Compatibility

Every AI tool you already use

One enhancement engine, two delivery surfaces. The Chrome extension handles web AI chats. The Mac desktop app handles native coding tools and anything with a text input.

Three before-and-after enhancements

One enhancement engine, different tools. Same pattern every time.

Content writing — ChatGPT, browser

Before

write me a product description for running shoes

After

You are a senior e-commerce copywriter for premium athletic brands. Write a product description for a trail running shoe priced at $180, targeted at runners with 5+ years of experience who care about durability and foot stability on uneven terrain. Tone: confident, technical without jargon. Output format: a 3-sentence headline, a 60-word overview paragraph, and a 4-item bulleted feature list. Constraints: no hype words (revolutionary, game-changing), no em-dashes, include at least one specific technical detail (e.g., drop, stack height, lug depth).

Code review — Cursor, desktop

Before

review this function for bugs

After

You are a senior engineer reviewing a pull request. For the function I paste below, produce a structured review with: (1) a 1-sentence summary of what the function does, (2) a bulleted list of bugs or incorrect behavior with exact line references, (3) a bulleted list of potential edge-case failures, (4) a bulleted list of readability or maintainability concerns (each marked [nit] or [important]). Constraints: do not rewrite the whole function — only suggest line-level changes. Do not flag style issues a formatter would catch.

Research — Claude, browser

Before

what are the differences between SAML and OIDC

After

You are an identity engineer explaining authentication to a senior backend developer evaluating both protocols for a B2B SaaS product. Compare SAML 2.0 and OIDC along these dimensions: protocol complexity, typical integration time, browser-only vs mobile support, SSO token format, revocation model, and ecosystem maturity. Output format: a markdown table with SAML and OIDC as columns and each dimension as a row, followed by a 3-bullet recommendation section. Constraints: under 300 words total, cite specific RFC or spec names where relevant.

What you get

Built for daily use across every AI surface

Global hotkey on macOS

⌘⇧P enhances highlighted text anywhere — Claude Code, Cursor, Antigravity, VS Code, terminal. Rebindable in settings.

Works in every browser AI chat

The Chrome extension drops a floating button into ChatGPT, Claude, Gemini, Copilot, and Perplexity. Same one-click flow on every site.

Prompts stay private

Your text is sent only to the enhancement model and is never used for training, analytics, or shared. Metadata only — never content.

By tool

The prompt enhancer for your AI tool

Every AI surface has its own quirks — Gemini's verbosity, Claude's strict format-following, agents that need scoped briefs. Each guide covers how enhancement works in that specific tool, with real before-and-after examples.

Questions.

An AI prompt enhancer is a tool that takes your plain-language input and rewrites it into a structured prompt before sending it to an AI. It automatically adds the role, context, instructions, constraints, and output format that professional prompts include — so you get higher-quality responses without writing scaffolding by hand. PromptAI enhances prompts in one click across ChatGPT, Claude, Gemini, and desktop tools like Claude Code, Cursor, and Antigravity.
