Prompt Enhancer for Claude Code, Antigravity, Cursor & VS Code
One hotkey turns vague prompts into structured ones — inside Claude Code, Antigravity, Cursor, VS Code, Warp, and anywhere else you type. PromptAI Desktop explained.
Most prompt enhancers live in the browser — helpful when you are working in ChatGPT or Claude on the web, useless the moment you open Claude Code, Antigravity, or Cursor. That is the gap PromptAI Desktop closes. One global hotkey, one rewrite, works in every AI tool you use on macOS.
If you have ever typed fix this bug into Claude Code and watched the agent wander for four minutes before asking you three questions you could have answered up front, this is for you.
Why desktop AI tools need this more than the web
The terminal is where prompt quality matters most, and where people rush the most. Three structural reasons:
- Agents act on your behalf. Claude Code and Antigravity do not just answer — they edit files, run commands, create branches. An under-specified prompt does not waste a chat turn; it wastes a real action. Twelve minutes of agent time on the wrong refactor is worse than thirty seconds of a generic response.
- Every token is billable context. In agentic loops, your prompt seeds a conversation that can span dozens of tool calls. A tight initial prompt compounds — the agent stays on-task, the context window stretches further, and you spend less per outcome.
- The UI punishes re-prompting. On the web you can edit-and-resend in a click. In a terminal agent, iterating usually means waiting for the current run, Ctrl+C, and starting over. Getting it right the first time has a real cost advantage.
And yet the inputs to these tools are tiny: a single-line text box at the bottom of a terminal, or a cramped chat panel beside the code. The ergonomics push you toward one-liners. PromptAI solves the input problem without changing how you type.
How the desktop app works
The workflow is one step, and that is the entire point:
- Type your prompt into Claude Code, Cursor, Antigravity — wherever.
- Hit
Cmd+Shift+P. - PromptAI captures the text, enhances it, and pastes the structured version back in place. Your cursor stays where it was.
You hit enter and send. Total round trip: about two seconds. No context-switching, no copy-paste dance, no separate window.
Because the capture happens at the OS level, it does not care what app you are in. If you can type into a text field, PromptAI can enhance the contents. That includes AI tools we have never tested against — if it accepts keyboard input, it works.
What it works with today
Verified and used daily by the team:
- Claude Code— Anthropic's agentic CLI
- Antigravity— Google's terminal coding agent
- Cursor — the Cursor chat panel and composer
- VS Code — Copilot Chat, Cline, Continue, any extension that takes prompt input
- Warp — Agent Mode and the AI command palette
- Ghostty, iTerm, Terminal.app — any terminal where you paste prompts into a CLI tool
- Zed — Zed AI panel
And everywhere else on macOS. If you find an app where the hotkey does not work, it is almost always because the app blocks simulated paste events (which is rare). Email us and we will look at it.
Three before-and-after examples from real agent work
Debugging
Step 1: Read the webhook handler file and identify the three most likely root causes for the reported bug based on the error context I provide. Do not read unrelated files.
Step 2: Ask me at most two clarifying questions — only if they are necessary to distinguish between the candidate root causes.
Step 3: Propose a specific fix as a diff, with a one-sentence explanation of why the change resolves the issue.
Constraints: do not refactor beyond the minimum needed. Do not touch tests unless the fix requires a test change. Do not run the server.
Refactoring
(1) Extract repeated logic into custom hooks. (2) Split the render body into named subcomponents if it exceeds 80 lines. (3) Keep TypeScript types co-located with their component. (4) Preserve every existing behavior exactly — same props, same DOM output, same class names.
Output:the refactored file as a single replacement, followed by a short bulleted list of what changed and why — one bullet per meaningful change. No preamble, no “here is the refactored code” opening.
Writing tests
Plan first: list the five most valuable test cases as one-line descriptions, ranked by which would catch the most regressions. Wait for me to confirm before writing the test file.
Then write: a Jest + React Testing Library test file covering exactly those five cases, using existing test patterns in the repo if any exist. Do not introduce new test utilities.
Finally: one short paragraph listing the edge cases you chose not to cover and a one-sentence reason for each.
In each case the user typed 5–8 words. The enhanced version is 90–140 words. The user did not write that scaffolding — PromptAI did. The difference in agent behavior is immediate: fewer detours, fewer clarifying questions, fewer unwanted file changes.
Why structure helps agents more than chats
Language models are conditional — every token in your prompt narrows the space of valid responses. In a chat, a vague prompt produces a generic paragraph, which you can skim and retry. In an agent, a vague prompt produces a plan, and the agent executes that plan before you see it. Structure is not a style choice in agent workflows; it is a cost-control mechanism.
We wrote about the underlying quality data in our study of 100 enhanced prompts vs. their raw originals. The headline number — responses usable as-is went from 19% to 58% — was measured on chat tools. Our internal agent traces suggest the gap is even wider in Claude Code and Cursor, because the cost of a bad first prompt includes all the downstream tool calls that follow from it.
Install and setup
PromptAI Desktop is a small menu-bar app. Download from the download page, drag it to Applications, sign in with the same account you use for the browser extension, and grant Accessibility permission so the hotkey can capture and replace text. Total setup time: about one minute.
macOS only for now — Windows is on the roadmap. The default hotkey is Cmd+Shift+P, rebindable in preferences.
Cmd+Shift+P, and watch the agent run a tighter loop. Download for macOS →What this does not replace
A prompt enhancer is not a substitute for context. PromptAI adds structure to what you typed — it cannot add information you did not provide. Three specific cases where enhancement alone will not save you:
- The agent needs repo-specific knowledge it does not have. If your codebase has unusual conventions, point the agent at the relevant files before you prompt. Enhancement structures the request, but the request still has to reference the right context.
- The task is genuinely ambiguous. “Make this better” does not get rescued by structure. If you do not know what better means, the agent will not either.
- You are in a long agent loop and the model has drifted. Mid-loop, the fix is usually to reset context, not to restructure a follow-up prompt.
For everything else — which is most of what you do with a coding agent every day — a one-hotkey rewrite is the highest-leverage single change you can make to the quality of your AI output.

Frequently asked questions
What is a prompt enhancer for Claude Code?
A prompt enhancer for Claude Code rewrites your raw prompt into a structured one before Claude Code runs it — adding role, task definition, constraints, and an explicit output format. PromptAI Desktop does this from a global hotkey (Cmd+Shift+P), so you never leave the terminal. You type a one-liner, hit the hotkey, and the enhanced prompt replaces it in place.
Does PromptAI work with Antigravity?
Yes. PromptAI Desktop captures and enhances text at the OS level, which means it works with Antigravity exactly the same way it works with Claude Code, Cursor, or any other app where you type into a prompt field. Because it operates on the active text input, there is no per-app integration to build — if you can type into it, PromptAI can enhance it.
How is this different from the PromptAI browser extension?
The browser extension enhances prompts inside ChatGPT, Claude, and Gemini web interfaces. The desktop app enhances prompts anywhere else you type — terminals, IDE chats, local AI apps, Electron apps. Same account, same enhancement engine, different surface. If you use both web and desktop AI tools, you install both.
Does it work with Cursor and VS Code Copilot Chat?
Yes to both. Cursor has its own chat panel; VS Code Copilot Chat is a panel inside VS Code. PromptAI Desktop works in either — put your cursor in the chat input, press the hotkey, and your prompt is replaced with the enhanced version. It also works with VS Code extensions like Cline and Continue.
Does it work with Warp and other AI terminals?
Yes. Warp's Agent Mode, Ghostty's AI features, and any other terminal with a text input are all supported. PromptAI treats them like any other OS-level text field. You type, hotkey, enhanced prompt lands, you hit enter.
Does PromptAI Desktop work on Windows?
Not yet. The current release is macOS only. Windows support is planned but not on a committed timeline. If you want to be notified when it ships, sign up and we will email Windows users specifically when the build is ready.
Can I change the hotkey?
Yes. The default is Cmd+Shift+P because it does not conflict with most coding tools, but you can rebind it to any combination in the app preferences. Some users prefer Cmd+E or Option+Space for faster muscle memory.
Does my prompt get sent to a server?
Yes — the enhancement runs on our backend so the model selection and prompt-engineering logic stay current. We do not train on your prompts, we do not store them beyond the immediate request, and the entire round trip typically takes under two seconds. If you need on-device enhancement for compliance reasons, email us — we are tracking demand for a local-only tier.
Do I need my own API key?
No. PromptAI Desktop uses our managed enhancement service, so you do not need to configure OpenAI, Anthropic, or any other API key. Your downstream AI tool (Claude Code, Cursor, etc.) uses its own credentials for the actual response — PromptAI only rewrites the prompt before it gets there.
Why do coding AI tools need a prompt enhancer more than chat tools?
Three reasons. First, coding AIs run autonomously — a vague prompt can waste minutes of agent time on the wrong task before you notice. Second, context windows in agentic loops cost real money; a tighter initial prompt reduces token spend. Third, unlike web chat, you do not have an easy UI to iterate and re-prompt — the terminal workflow rewards getting it right the first time.
