Submit any text via the form \u2014 email, blog paragraph, social caption, proposal, or product description. GPT-4o-mini rewrites it in five distinct tones simultaneously: Professional, Casual, Persuasive, Concise, and Empathetic. All five versions are assembled into one Google Doc saved to your Drive folder. Slack gets an instant preview of the Concise version so your team can act immediately.\n\n## How it works\n- **1. Form \u2014 Content Tone Rewriter** collects the original text, content type, project name, and target audience\n- **2. Set \u2014 Config Values** stores Drive folder ID, Slack channel, company name, and maps all form fields\n- **3. AI Agent \u2014 Tone Rewriter** uses GPT-4o-mini to rewrite the text in all five tones at once\n- **6. Code \u2014 Assemble Document Content** builds the full doc text with all five versions and the Slack preview message\n- **7. Code \u2014 Convert to Binary** encodes the doc as a binary file for Drive upload\n- **8. Google Drive \u2014 Upload Tone Doc** saves the complete five-version document to your Drive folder\n- **9. Slack \u2014 Send Concise Preview** posts the Concise version as a quick team preview\n\n## Set up steps\n1. In **2. Set \u2014 Config Values** \u2014 replace YOUR_GOOGLE_DRIVE_FOLDER_ID, YOUR-SLACK-CHANNEL, and YOUR COMPANY NAME\n2. In **4. OpenAI \u2014 GPT-4o-mini Model** \u2014 connect your OpenAI credential\n3. In **8. Google Drive \u2014 Upload Tone Doc** \u2014 connect your Google Drive OAuth2 credential\n4. In **9. Slack \u2014 Send Concise Preview** \u2014 connect your Slack OAuth2 credential and invite the bot to your channel\n5. Activate the workflow and copy the Form URL from node 1"
