## Trace OneTap

### Direct answer

Trace OneTap is a native macOS voice app from EndlessRiver. From the app already in use, a person can hold or double-tap the right Option key to dictate at the cursor, transform selected text, draft a reply, or ask a question. Writing actions can insert into the intended field; ordinary questions stay in a separate response card.

### What OneTap does

- Dictates natural speech at the cursor in Mac apps
- Uses a personal vocabulary for exact names, acronyms, product terms, and jargon
- Supports English, Hinglish, Indian languages, and code-switching in automatic language mode
- Drafts replies and other text from a spoken request
- Rewrites, shortens, changes the tone of, or translates selected text
- Keeps ordinary assistant answers in a response card rather than pasting them into the active field
- Re-checks the intended app and field before insertion
- Blocks password fields

### Shortcut and workflow

1. Focus the app and field where the result belongs.
2. Hold right Option, speak, and release; or double-tap right Option for hands-free listening.
3. A dictation or writing request is inserted at the intended destination after a destination check.
4. A normal question appears in a response card with copy, follow-up, and insert controls.

### Platform and installation

| Field | Value |
|---|---|
| Platform | macOS |
| Processors | Universal Apple silicon and Intel build |
| Distribution | Developer ID signed, Apple-notarized DMG |
| Required permissions | Microphone, Speech Recognition, and Accessibility |
| Account | Trace account |
| Price | Free with a Trace account |
| Glasses required | No |

### Privacy and insertion safety

OneTap blocks password fields. Audio is not stored in Trace voice history. Before inserting generated text, OneTap checks that the original app and field are still the intended destination. If the destination changed, the result remains in a response card for manual copy or insertion.

### Trace OneTap FAQ

**Does OneTap always type into the active app?**

No. It writes only when a request clearly asks to dictate, draft, reply, rewrite, translate, or insert. Normal questions open in a response card.

**Are Trace Glasses required?**

No. OneTap runs directly on a Mac. Trace Glasses are a separate hands-free product connected through the same Trace account.

**Can OneTap recognize names and acronyms?**

Yes. A person can add names, acronyms, product terms, and jargon to a personal vocabulary. Trace uses those spellings as recognition hints across supported dictation surfaces.

**Can OneTap handle English and Hinglish?**

Yes. Automatic mode is designed for English, Hinglish, Indian languages, and code-switching. It preserves the language mix and script spoken unless the person asks for a translation.

**What happens if the user changes apps while OneTap is working?**

OneTap checks that the original app and field are still the intended destination before inserting. If the destination changed, the result stays in a response card.
