TypeBoost is a native macOS and iOS writing assistant that works inside any app. Select text, hit a keyboard shortcut, and apply custom AI prompts to rewrite, translate, summarize, or transform your writing instantly. It supports voice input, syncs prompts across devices, and lets you choose your preferred AI model. TypeBoost stays out of your way until you need it, keeping you in flow without copy-pasting between tools. Built for writers, marketers, freelancers, and anyone who writes a lot on Apple devices.

• System-Wide Text Actions: Select text in any macOS app, trigger TypeBoost with a keyboard shortcut, and apply AI-powered transformations without leaving your current workflow.
• Custom Prompt Templates: Create and save your own prompt templates that match your writing style, tone, and intent. Define once, reuse across every app.
• Voice Mode: Dictate instructions or entire passages using voice input. Speak naturally and TypeBoost converts your words into polished text up to 4x faster than typing.
• Granular Edit Control: See exactly what the AI changed in your text. Accept or reject individual edits so you stay in control of every word.
• Cross-Device Sync: Prompts and settings sync in real-time between your Mac and iPhone. Capture ideas on the go and pick up where you left off on desktop.
• Multi-Language Support: Write in one language and translate to another instantly. TypeBoost supports 95 languages while preserving your natural tone.
• AI Model Choice: Pick your preferred AI provider, including OpenAI, Anthropic, and Google, to power your text transformations.
• Privacy-First Design: TypeBoost only reads text you explicitly select when you trigger it. No background scanning, no passive monitoring of your documents or apps.

• No App Switching Required: Apply AI to text directly inside whatever app you're already using, whether it's Mail, Safari, Webflow, or Keynote. Eliminates the constant tab-switching to ChatGPT.
• Fully Customizable Prompts: Unlike generic AI tools, you define exactly how the AI responds, matching your voice, structure, and intent for consistent output.
• Native macOS and iOS Performance: Runs as a native app, not a browser extension. Launches in milliseconds, uses less battery and memory, and feels like a natural part of your operating system.
• Voice Input for Fast Drafting: Speak your ideas and get polished text back. Particularly useful for capturing thoughts on iPhone between meetings or on the move.
• Strong Privacy Controls: Only accesses text you select at the moment you trigger it. Requires minimal permissions and does zero background data collection.

• Apple Ecosystem Only: Available exclusively on macOS and iOS. No Windows, Android, or Linux support, which limits who can use it.
• Limited Keyboard Shortcuts: Currently only offers two shortcuts (Text Mode and Voice Mode). Custom shortcuts for individual prompts are not yet available and only on the product roadmap.
• Credit-Based Usage Limits: The free plan includes a one‑time allocation of 50,000 credits and 10 minutes of voice input. Users who consume these credits may need a paid plan for ongoing use.
• Accessibility API Edge Cases: Text extraction relies on the macOS Accessibility API, which can occasionally behave inconsistently with sandboxed or non-standard apps.

• Email Writing and Outreach: You write dozens of emails daily and need them to sound professional fast. Select your draft in Mail or Gmail, trigger TypeBoost, and apply a saved prompt to polish tone, fix grammar, or rewrite for clarity, all without opening another app.
• Social Media Content Creation: You want to turn rough ideas into polished LinkedIn or X posts. Drop your raw thoughts into any text field, apply your "clean up for LinkedIn" prompt, and get a post that still sounds like you but reads sharper.
• Multilingual Translation: You work with international clients or freelancers and need quick, natural-sounding translations. Write in your native language and use TypeBoost to translate into any of 95 supported languages while keeping your original tone intact.
• Freelance Copywriting: You're a designer or developer who also writes client copy. Use TypeBoost inside tools like Webflow or Figma to write and refine copy without switching to a separate AI chat window.
• Voice-First Drafting on iPhone: You're commuting or walking and want to capture an idea before you lose it. Open TypeBoost on your iPhone, speak your thoughts, and let AI turn them into a clean draft that syncs to your Mac for later editing.
