✅ Fix Grammar

🎯 Custom Workflows

## Sound Familiar?

Common writing bottlenecks this solves

### You send vague prompts and get weak output

Quick prompts often miss context, constraints, or format. You end up regenerating instead of getting a good first answer.

### Voice dictation sounds casual or messy

Dictating is fast, but the wording is often loose. You need clean, structured instructions before sending to AI.

### You switch between many AI surfaces

You use ChatGPT, Gemini in Google Workspace, and other tools. You need one prompt workflow that works everywhere.

## How It Works

A simple flow to get better results

1

### Draft or dictate your intent

Write your rough request in any app, like Notes, Docs, or email. A short draft is enough.

2

### Run Improve Prompt in RewriteBar

Select the text, trigger RewriteBar, and choose Improve Prompt or Strengthen Prompt. RewriteBar adds structure and clear requirements.

3

### Paste into ChatGPT, Gemini, or any AI

Copy the improved prompt and send it where you work. Same flow across standalone and integrated AI chats.

## Before & After

Real rewrites you can apply in seconds

After

Tone

Before

rewrite copy in a friendly tone

After

Rewrite this text in a friendly, conversational tone. Keep the meaning and similar length. Preserve product names and links. Return plain text only.
