Prompten: The Mac App That Turns Rough Ideas Into Perfect AI Prompts in One Keystroke
You have been there. You open ChatGPT, Claude, or your code editor's AI assistant, and you type something like: "explain react hooks for a junior dev" — and you get a response that is technically correct but shallow, generic, and missing the exact context that would have made it genuinely useful.
The problem is not the AI. The problem is the prompt.
Prompt engineering is a real skill. A well-structured prompt tells the AI exactly who it is speaking to, what constraints it is working under, how the output should be formatted, and what success looks like. The difference between a mediocre prompt and a great one is often the difference between a mediocre answer and a transformative one.
But writing great prompts from scratch, every single time, for every rough idea you want to explore — is slow, interrupts your flow, and requires a level of craft most people have not had time to develop.
That is the problem Prompten solves.
What Is Prompten?
Prompten is a macOS menu bar application built by BlinkAI that rewrites your rough text into a precise, well-structured AI prompt — using a single global hotkey, from anywhere on your Mac.
Here is the complete workflow:
- Highlight any text in any app — a rough question in Notion, a vague task in Linear, a half-formed idea in your code editor's comment field
- Press ⌘ ⇧ E (fully customisable)
- Prompten captures your selection, sends it to your chosen AI model, and pastes the enhanced prompt back in place — in under a second
No window switching. No copy-paste. No leaving your flow state.
The Problem With Rough Prompts
Most people use AI tools the same way they use a search engine — they type a short, informal query and hope the AI figures out what they meant. Sometimes it works. More often, the result is surface-level and generic.
Compare these two prompts:
Rough version:
"explain react hooks for a junior dev"
Prompten-enhanced version:
"You are a senior React engineer mentoring a junior developer with six months of JavaScript experience. Explain how React Hooks work — specifically useState, useEffect, and useCallback. Use real-world analogies for each hook, provide a practical code example, and highlight the three most common mistakes beginners make. Structure your response with clear headings, keep each explanation under three sentences, and end with a summary table comparing when to use each hook."
The second prompt will get a dramatically better response from any AI model. And crucially — Prompten wrote it for you in under a second, from a six-word rough idea.
How Prompten Works Under the Hood
Prompten is built with Tauri — a Rust-based framework for native macOS applications — and uses macOS Accessibility APIs to read your selected text and inject the result back without touching your clipboard in most cases.
When you press the hotkey, a floating HUD window appears near the center of your screen showing the pipeline status:
- Prompt sent to AI model — your text is dispatched to your configured provider
- Thinking… — the model processes your request
- Fetching Enhanced Prompt.. — the response streams in
- Pasted ✓ — the result replaces your selection and the HUD fades out
The entire round trip typically takes two to four seconds depending on the model and your internet speed. With a local Ollama model on Apple Silicon, it can be under one second.
Supported AI Providers
One of Prompten's strongest features is its flexibility around AI providers. You are never locked into a single model or subscription.
Cloud Providers
| Provider | Notes |
|---|---|
| OpenRouter | Default — free tier included, access to dozens of models |
| Anthropic Claude | Claude 3.5 Sonnet, Haiku, Opus |
| OpenAI | GPT-4o, GPT-4o Mini, and others |
| Custom / OpenAI-compatible | DeepSeek, Groq, any OpenAI-spec API |
Local Models (via Ollama)
For users who want complete privacy or zero ongoing API costs, Prompten integrates directly with Ollama. The built-in model browser lets you download and switch models with a single click:
| Model | Size | Best For |
|---|---|---|
| Gemma 3 4B | ~2.5 GB | Speed + quality on Apple Silicon |
| Gemma 3 1B | ~0.8 GB | Ultra-fast, low RAM |
| Llama 3.2 3B | ~2 GB | Strong instruction following |
| Phi-4 Mini | ~2.2 GB | Structured output tasks |
| Qwen 2.5 3B | ~2 GB | Multilingual prompts |
Once a local model is downloaded, Prompten works completely offline. Your text never leaves your machine.
Custom Personas: One App, Every Role
The default persona — a generic prompt enhancement expert — works for everyone. But Prompten's real power comes from custom personas.
A persona is a system prompt that tells the AI who it is and how to rewrite your input. You create as many as you want and switch the active one with a single click from the Personas tab.
Example Personas
Senior React Developer
"You are a senior React developer. Rewrite the user's rough text into a precise prompt focused on React, TypeScript, and modern frontend patterns. Include component structure, hooks, and performance constraints. Output ONLY the improved prompt."
Product Manager
"You are an experienced product manager. Rewrite the user's rough text into a structured product requirement with user stories, acceptance criteria, and success metrics."
Content Writer
"You are a senior content strategist. Rewrite the user's rough idea into a detailed content brief including target audience, SEO intent, tone of voice, approximate word count, and key sections to include."
Data Analyst
"You are a senior data analyst. Rewrite the user's rough request into a structured analytical prompt specifying the dataset context, the metric to analyse, the visualisation type, and the business question to answer."
This means a developer, a PM, a writer, and an analyst can all use the same app — each getting prompts tuned precisely to their professional context.
Privacy and Security
Prompten is designed from the ground up with privacy as a first principle.
- Your text goes directly from your Mac to your AI provider's API — it does not pass through BlinkAI's servers
- BlinkAI only verifies your account and deducts one credit per successful enhancement
- No telemetry, no analytics, no content logging of any kind
- Local model users have complete privacy — with Ollama, nothing leaves your machine at all
The only network calls Prompten makes are to your configured AI provider's endpoint (over HTTPS), and to BlinkAI's API for authentication and credit management.
The Credits System
Prompten uses a credit-based system tied to your BlinkAI account. One credit is deducted each time a prompt is successfully enhanced and pasted.
- Credits are never deducted for failed calls — if the AI returns an error or nothing is selected, your balance is unchanged
- Credits never expire — top-up credits purchased at any time remain in your account
- The real-time credit balance is visible in the Prompten sidebar and updates automatically after every enhancement
This model means you only pay for value delivered. No monthly fee that drains away whether you use the tool or not.
System Requirements
- macOS 12 Monterey or later
- Apple Silicon (M1, M2, M3, M4) or Intel — both fully supported
- Accessibility permission — required for Prompten to read your selection and paste results (one-time grant in System Settings → Privacy & Security → Accessibility)
- Internet connection — required for cloud providers; not required when using Ollama local models
Getting Started in Under 5 Minutes
Step 1: Create a BlinkAI account
Go to blinkai.co/register and create a free account. You receive 20 free enhancements to start — no credit card required.
Step 2: Download Prompten
Download the Prompten Mac app from your BlinkAI account dashboard. Open the
.app file and move it to your Applications folder.Step 3: Grant Accessibility Permission
On first launch, Prompten shows a yellow setup card. Click Open Settings and toggle Prompten on in System Settings → Privacy & Security → Accessibility. This is a one-time step.
Step 4: Sign In
Enter your BlinkAI email and password. Prompten connects to your account and loads your credit balance automatically.
Step 5: Choose Your Provider
Go to the Models tab, select your provider (OpenRouter is recommended for beginners — it has a free tier with no API key required beyond your BlinkAI login), and save your configuration.
Step 6: Test It
Open any app — Notes, VS Code, your browser — type a rough idea, select it, and press ⌘ ⇧ E. Watch the HUD appear, and see your enhanced prompt replace the selection in under three seconds.
Prompten vs Alternatives
| Feature | Prompten | PromptMan | Apple Intelligence |
|---|---|---|---|
| Global hotkey (any app) | ✓ | ✓ | ✓ |
| Custom rewrite personas | ✓ | Limited | ✗ |
| Local models (Ollama) | ✓ | ✗ | ✗ |
| BYOK (bring your own key) | ✓ | ✗ | ✗ |
| OpenRouter free tier | ✓ | ✗ | ✗ |
| Works offline | ✓ | ✗ | Partial |
| Prompt history + search | ✓ | ✓ | ✗ |
| Privacy (no content logging) | ✓ | Unknown | Partial |
| macOS only | ✓ | ✓ | ✓ |
| One-time purchase option | ✓ | ✗ | Free |
The key differentiator is the combination of local model support, unlimited custom personas, and full provider flexibility. No other tool in this category lets you run completely offline with Ollama while also supporting seven cloud providers with your own API keys.
Apple Intelligence is free and deeply integrated, but it cannot use external AI providers, has no custom personas, and its rewrite capabilities are limited to predefined modes (proofread, rewrite friendly, summarise). Prompten's output is structurally richer and more tailored to AI workflows.
Pricing
Prompten is available on three tiers:
Free
- 20 prompt enhancements per month
- OpenRouter free models
- 1 custom persona
- Prompt history (50 items)
Pro — $9/month
- 500 prompt enhancements per month
- All AI providers including Claude and GPT-4o
- Unlimited custom personas

Additional credit top-ups are available at any time and never expire. This makes Prompten genuinely pay-per-use — you spend credits only when a prompt is successfully enhanced.
Who Is Prompten For?
Developers who live in VS Code, Cursor, or Xcode and want every AI coding prompt to be structured with proper context, constraints, and output format — without stopping to write it manually.
Product managers who are drafting requirements, writing tickets, or using AI to synthesise research, and need prompts that produce PRD-quality output rather than generic lists.
Writers and marketers who use AI as a drafting partner and are tired of prompts that produce generic content — custom personas let them define their brand voice and target audience once, then apply it automatically.
Researchers and analysts who need AI to engage with datasets, methodologies, and academic context — not produce surface-level summaries.
Anyone who uses AI tools daily and has ever thought "the response was okay but not quite what I needed" — because more often than not, the prompt was the problem.
The Bottom Line
Prompten is not a prompt library. It is not a clipboard manager. It is not a chatbot interface.
It is a tool that makes every prompt you write better, automatically, in under a second, without interrupting what you are doing.
If you use AI tools more than a few times a day and you have not systematically invested time in learning prompt engineering — and most people have not — Prompten gives you that skill for free, every time you press a hotkey.
The free tier is generous enough to evaluate it properly. The lifetime plan at $49 pays for itself the first week you use it seriously.
Frequently Asked Questions
Does Prompten work in every Mac app?
Yes. It uses macOS Accessibility APIs which work system-wide — VS Code, Chrome, Notion, Slack, Terminal, Xcode, Notes, Pages, and every other standard Mac app that supports text input.
Will it slow down my computer?
No. Prompten is a native macOS app built in Rust, which is one of the most efficient languages available. It uses negligible CPU and RAM when idle in the menu bar.
Is my text stored anywhere?
No. Your selected text goes directly from your Mac to your AI provider's API. BlinkAI does not receive, store, or log the content of your prompts.
Can I use it without an internet connection?
Yes — install Ollama, download a local model from Prompten's model browser, and select Ollama as your provider. All processing happens on your Mac with no internet required.
What happens if I run out of credits mid-enhancement?
Prompten checks your balance before firing the hotkey. If your balance is zero, a "Credits Expired" popup appears immediately with a direct link to purchase more — your selected text is left unchanged.
Can I change the hotkey?
Yes, from Settings → General. Click the shortcut field, press your desired combination, and click Apply. The change takes effect immediately without restarting.
