Works with every Cursor surface

PromptAI operates at the OS level on the currently selected text — Cursor's input fields are no different from any other text area.

Composer

Multi-file edits. Enhanced prompts specify which files to touch, which to leave alone, and what the diff should look like.

Chat

Conversational Q&A with your codebase. Enhanced prompts add role, audience, and output format (markdown, code-only, table).

Cmd+K (inline)

Single-file inline edit. Enhanced prompts pin scope tightly — refactor what, leave what, keep what pattern.

Three real Cursor prompts, before and after

Vague prompts produce vague diffs. Enhanced prompts produce targeted, reviewable edits.

Composer — multi-file refactor
What you type
refactor this auth module to use server actions
After ⌘⇧P
Role: senior Next.js engineer, App Router specialist. Scope: refactor the auth module at @src/lib/auth to use Next.js server actions instead of route handlers. Files to touch: - @src/lib/auth/session.ts - @src/lib/auth/middleware.ts - @src/app/api/auth/[...]/route.ts → delete, replace with server actions - Any components calling /api/auth — update to use action imports Files to leave alone: - @src/app/(auth)/layout.tsx - Database schema Constraints: - Preserve existing JWT format - No breaking changes to the session cookie name - Keep current rate limits Output: one diff per file, in commit order. No prose between diffs.
Chat — codebase Q&A
What you type
how does our caching work
After ⌘⇧P
Role: staff engineer who just joined this codebase and needs to explain caching to a new teammate. Audience: junior engineer with 1 year experience. Assumes they know HTTP basics but not our custom stack. Task: explain how caching works in this codebase. Reference @src/lib/cache and any Redis/in-memory layers you find. Output format: markdown with these sections: 1. Layers (where caching happens) 2. Invalidation (how/when caches are cleared) 3. Gotchas (2-3 things they'll trip over) 4. One concrete example walking through a request Constraints: cite file paths and line numbers. No hand-waving.
Cmd+K — inline edit
What you type
add error handling
After ⌘⇧P
Role: senior TypeScript engineer. Task: add error handling to this function. Scope: only this file. Do not modify imports beyond adding a typed Error subclass if needed. Requirements: - Preserve return type on success - Wrap the external call in try/catch - Throw a custom error class (create one inline if absent) — don't throw raw Error - Log once at catch site with structured fields {fn, input, cause} - No swallowing errors silently Output: the updated function only. No prose.

Setup takes two minutes

01

Download the Mac app

PromptAI Desktop is a 176 MB universal binary — Apple Silicon and Intel. macOS 12 or later.

02

Grant Accessibility permission

macOS asks once. PromptAI uses it to read the text you highlight and paste the enhanced version back.

03

Open Cursor. Try it

Type your prompt. Select it. Hit ⌘⇧P. The enhanced version replaces your text, ready to send.

Smaller diffs

Explicit scope means Cursor touches fewer files. Reviewers stop rubber-stamping 800-line PRs.

Consistent style

Role and stack constraints in every prompt. Output matches your conventions without babysitting.

Fewer iterations

One well-structured prompt replaces three back-and-forth rounds. Ship in the time you used to spend clarifying.

Questions.

A Cursor prompt enhancer rewrites whatever you type in Cursor's Composer, Chat, or Cmd+K into a structured prompt — adding the role, file context references, stack constraints, and an explicit output format. PromptAI's Mac desktop app adds a ⌘⇧P hotkey that enhances the selected text in place, no copy-paste required.
