PromptDC

Choose from nine built-in writing profiles:

• Grammar corrects spelling, grammar, punctuation, and awkward phrasing
• Email turns rough notes into a clear, complete email
• Social sharpens posts for the platform and audience
• Summarize distills selected text into the essential points
• Reply drafts a clear response to a message
• Professional gives your writing a polished workplace tone
• Concise removes filler while preserving the meaning
• Explain makes complex text easier to understand
• Image Prompt expands an idea into a detailed image-generation prompt

Select part of an email, post, document, article, or webpage and run the profile you need. In editable text, PromptDC can replace only the selected text or rewrite the field in place. On read-only pages, it copies the improved result to your clipboard.

Create custom profiles with your own instructions, then set a default profile for each website. Use Grammar on Gmail, Social on X, Professional on LinkedIn, or any setup that matches your workflow.

✨ FLOATING TOOLBAR, SELECTION & CUSTOM ACTIONS

The floating toolbar appears beside text you select anywhere on the web. It also appears as you work in editable text boxes, unless you enable Selection-only mode.

• Click Enhance to run the active profile
• Switch profiles without leaving the page
• Use Action to tell the AI exactly what to do with the text
• Open Community and Library prompts
• Open Settings in the sidebar

Need something a profile doesn't cover? Open the profile switcher, type a custom Action such as "shorten this", "make it friendlier", or "translate to Spanish", and press Enter. PromptDC applies your instruction to the selected text or the text box as a one-off, without changing your profiles.

After an enhancement, open Changes to see deletions in red and additions in green. Switch to Edit to adjust the result before accepting or copying it.

🪄 ENHANCE PANEL IN THE SIDEBAR

Sometimes the text you want to improve isn't on the page yet. Open the sidebar and use the Enhance panel, a scratchpad that works exactly like the PromptDC desktop app:

1. Pick a profile, or switch to Action and describe what to do 2. Paste or type your text 3. Click Enhance

The result replaces your text. Review it in Changes or Edit view, copy it anywhere, or hit Undo to get your original back. Perfect for polishing a message before you paste it into a form, chat, or document that has no text box support.

💻 CODING MODE

Turn a vague coding request into a clear, structured prompt with requirements, constraints, edge cases, and an expected output. Use Code mode with ChatGPT, Claude, Lovable, Replit, and other AI coding tools to get implementation-ready instructions without leaving the text box.

Coding sites default to Code mode. You can still switch profiles or create your own per-site rule whenever your task changes.

📚 COMMUNITY & LIBRARY

• Browse prompts and system instructions shared by the community
• Keep your own reusable prompts in My Library
• Type "//" in any text field to search and insert a saved or community prompt
• Insert useful prompts without opening another tab or copying and pasting

💾 SAVE TO LIBRARY

Found text or a prompt you want to reuse?

1. Select it on any webpage 2. Right-click and choose "Save to Library" 3. Add a name, description, type, category, and tags 4. Find it later from My Library or with the "//" shortcut

Hi Sam,

My dentist appointment was moved, so I can't make our 2:00 PM catch-up tomorrow. I'm sorry for the late change.

Could we reschedule for Thursday morning? I'd still like to go over the launch notes and next steps. Please let me know if that works for you.

Coding mode

Before:

"create a food tracking app"

After (Rewritten):

"Design and implement a responsive food tracking app with a hero section, a daily food log (date, foods, calories/macros), and an Add Food modal (name, calories, protein, carbs, fats). Include loading, empty, and error states, responsive layout, and semantic HTML. Structure the codebase with small, reusable components (FoodLog, AddFoodModal, FoodEntryCard) using design system tokens, with no inline overrides."

❓ FAQ

Q: Does PromptDC work with ChatGPT and Claude? A: Yes. Use Writing profiles to improve text and general prompts, or switch to Code mode to turn a rough coding request into a structured implementation prompt directly on ChatGPT or Claude.

Q: Does it work outside AI sites like Gmail or any blog? A: Yes. In Gmail and other editable text boxes, select text or focus the field, choose a profile, and click Enhance. On a blog or other read-only page, select any text and use the floating toolbar. PromptDC shows the result and copies it to your clipboard so you can use it wherever you need it.

Q: What if none of the profiles fit what I need? A: Use Action. Type what you want, such as "make this shorter" or "turn this into bullet points", and PromptDC applies your instruction to the text as a one-off. Actions work from the floating toolbar and from the sidebar Enhance panel.

Q: Can I enhance text that isn't on a webpage? A: Yes. Open the sidebar Enhance panel, paste or type your text, pick a profile or an Action, and click Enhance. Copy the result anywhere, or Undo to restore your original.

Q: What's the // shortcut? A: Type "//" in any text field to search prompts from your library and the community, then insert one without leaving the page.

Q: Can I use a custom system prompt? A: Yes. Open the sidebar, enable Override System Prompt, and enter your own instructions. You can also create custom profiles and use Always Include for rules that should apply to every enhancement.

Q: How do I turn it off on a site? A: Click the power button on the floating toolbar. PromptDC stays disabled on that site, even after a refresh. To turn it back on, right-click the page and choose "Enable PromptDC on this site."
