The Privacy Problem with Writing Tools

Most grammar and writing tools require sending everything you type to their servers. This creates a fundamental privacy concern: your confidential emails, legal documents, medical notes, and personal thoughts are processed and potentially stored by third parties.

At TypeSafe, we believe you shouldn't have to choose between better writing and data privacy. That's why we built Local Mode.

How Local Mode Works

When you enable Local Mode in TypeSafe, all grammar checking and text processing happens entirely on your device. Here's what that means:

  • Zero network requests - Your text never leaves your computer
  • Works offline - No internet connection required
  • Instant processing - No server latency or delays
  • Complete privacy - Mathematically impossible for us to see your text

When to Use Each Mode

Local Mode - Maximum Privacy

Use Local Mode when writing sensitive content: confidential business emails, legal documents, medical notes, personal journals, or anything you want to keep 100% private.

Cloud Mode - Maximum Power

Switch to Cloud Mode for non-sensitive writing when you want access to our most advanced AI-powered rewriting features. Even in Cloud Mode, we never store your text—we process it and immediately discard it.

Technical Implementation

Local Mode uses WebAssembly to run our grammar engine directly in your browser. The entire language model is downloaded once and cached locally, making subsequent corrections lightning-fast with zero network overhead.

Privacy Commitment

Regardless of which mode you choose, TypeSafe never stores what you write. We collect only anonymized usage metrics (like number of corrections) to improve the product. Your actual text content is never logged, stored, or used for training.
