Zapper — AI Prompt Optimizer

Rewrites vague prompts into clear, specific ones for Claude, ChatGPT and Gemini. Click Zappy before you hit send.

Zapper rewrites your prompt before you send it to Claude, ChatGPT or Gemini. You type something quick, like "fix this app," and instead of the AI firing back four questions before it actually helps, Zapper turns it into something specific enough to get a real answer on the first try. No more round trips just to explain what you meant. Click Zappy sitting on the composer. He rewrites your prompt: scoped, direct, with the obvious assumptions stated instead of left for the AI to guess wrong. Turn on Power Zap and he pulls in your recent chat history too, so the rewrite actually knows what you're working on instead of just reacting to one line. You don't have to accept the whole rewrite either. Go through it line by line and keep only the parts you want. Max plan adds Rogue Prompt Detection. Paste in a README, someone's setup instructions, a random code snippet, whatever, and Zappy checks that pasted content for prompt injection and hidden commands before you run it. Copying random instructions off the internet into an AI chat is exactly how people get burned, and this catches it in the same request, no extra step, no extra wait. Works across Claude, ChatGPT and Gemini. Free to start, 20 rewrites and 3 context aware rewrites a month, no card needed. Paid plans raise the limits and let you plug in your own Anthropic key if you want it unmetered. Zappy does nothing until you click him. No background scraping, no auto-rewriting while you type.
