AI prompt & writing assistant in every text box

PromptDC is an AI prompt & writing assistant that improves anything you type into AI — coding prompts and writing alike. It rewrites vague developer prompts into precise, implementation-ready instructions for AI code generation, and fixes grammar, tone, emails, replies, and social posts on any website. One extension, one click, right inside the box where you're typing.

One-click prompt & text rewrites, inside the box

PromptDC lives in the text box you're already typing in. Select your text or press the shortcut and PromptDC rewrites it in place — no copy-pasting into a separate app, no context switch. It works the same whether you're writing a Cursor prompt, a Gmail reply, or a LinkedIn post.

  • Rewrite selected text or the whole field with one click or a keyboard shortcut
  • Keep your voice — PromptDC sharpens clarity and structure, it doesn't replace your intent
  • Preview every change before it's applied — nothing replaces your text until you click Accept

Platform-aware rewrite profiles

PromptDC is not a one-size-fits-all enhancer. On supported web platforms it detects the AI product you're using and applies the right rewrite profile; in the IDE extension you pick the target model or IDE so the rewrite uses the correct system-prompt assumptions.

  • Auto-detects the current AI tool (ChatGPT, Claude, Gemini, Grok, Cursor, Lovable, Bolt, and more)
  • Model/IDE selection in the IDE extension for coding-accurate rewrites
  • Coding mode produces precise, implementation-ready specs for AI code generation

Writing profiles for everyday text

Beyond coding, PromptDC ships nine built-in writing profiles that fix grammar, adjust tone, and reshape whatever you're writing — a practical Grammarly alternative that follows you across the web instead of one app.

  • Grammar, Email, Social, Reply, Professional, Concise, Summarize, Explain, and Image Prompt profiles
  • Per-website rules: set Grammar on Gmail, Social on LinkedIn, and the right rewrite runs automatically
  • Floating toolbar works everywhere on the web in any text box, with tuned per-site defaults, a right-click action, and a shortcut for selected text

Bring your own API key (BYOK)

On the Lifetime plan you connect your own OpenAI, Claude, Gemini, or Grok key and pick which provider and model to use — you pay your provider for usage (typically ~$1–3/month) with no recurring PromptDC subscription on top. Pay once, use it forever.

  • Use your own key and model; your provider bills you for usage
  • No monthly SaaS fee on the Lifetime plan — one-time payment
  • Your key is sent securely through PromptDC's backend to your chosen provider with each request

Frequently asked questions

What does the PromptDC extension actually do?

PromptDC rewrites anything you type into an AI tool or text box — coding prompts and writing alike — into clearer, higher-quality text, right inside the box where you're typing. It's a prompt enhancer for AI code generation and a Grammarly alternative for writing, in one extension.

Which browsers and tools does PromptDC support?

PromptDC ships a Chrome extension and IDE extensions. The Chrome extension works on any website, in any text box and on any text you select, including Gmail, LinkedIn, X, ChatGPT, Claude, Cursor, Lovable, Bolt, and Replit.

How much does PromptDC cost?

PromptDC Pro is $9/mo (200 enhancements/month), Enterprise is $15/mo (unlimited enhancements), and the Developer Lifetime plan is a one-time payment from $69 (tiered launch pricing rising $69 → $99 → $124 as tiers sell out) where you bring your own OpenAI, Claude, Gemini, or Grok API key — you then pay only your provider's usage, typically ~$1–3/month. PromptDC has no free plan.

Does PromptDC work for both coding and writing?

Yes. Coding mode rewrites vague developer prompts into implementation-ready instructions for AI code generation; writing mode fixes grammar, tone, emails, replies, and social posts on any website. The active mode is chosen per site, and you control the profiles.
