Same chat box. Better question. Better answer.

Tab through five real PrePrompt rewrites — the actual output the extension would send, no edits.

PrePrompt sends
Write a LinkedIn post announcing my departure from a senior PM role at a major tech company to launch my own AI startup. The tone should feel authentic and genuinely reflective—avoiding the clichéd tropes of typical ‘I quit my job to become a founder’ posts (e.g., calling it a ‘leap of faith,’ generic gratitude, or hype-focused language). Focus on honest insight into why this move made sense for me personally, what I actually learned, and what I’m genuinely excited about—not what sounds impressive.
+ Role+ Context+ Format+ Constraints
The real reason

Your AI isn’t missing intelligence. It’s missing context.

Most generic AI answers aren’t an AI problem. They’re a prompt problem. Every vague prompt is missing the same three things.

Missing context

The AI doesn’t know who you are, what you’ve already tried, or what success looks like. So it gives the safest possible answer.

Missing constraints

No length, no format, no tone, no anti-patterns. The result is a generic wall of text instead of the specific answer you wanted.

Missing format

No structure, no table, no bullets. You spend 10 minutes reshaping the answer instead of using it.

PrePrompt fixes all three before you hit Send.

How it works

Three steps. Same chat box.

PrePrompt sits next to the Send button on every chat you use. The browser does the typing, PrePrompt does the rewriting, the LLM does the answering.

01

Type as usual

Open ChatGPT, Claude, Gemini, or Perplexity. Type your prompt the way you always do. PrePrompt reads only the text in the chat box — nothing else on the page.

$ you → "help me plan a launch"
02

Click Rewrite

The PrePrompt button sits next to Send. One click runs your prompt through our rewriter — adding structure, specificity, and the context the model needs to give you a useful answer.

$ score = 41 · route = rewrite
03

Send the better one

The rewrite lands in the same textarea in under a second. Hit Send. Don't like it? Undo restores your original — same key combo as everywhere else.

$ preprompt → chatgpt("Plan a launch …")
Real users

Marketers, founders, devs, students — same fix.

Four kinds of people. Four kinds of vague prompts. Same Rewrite button. See if you recognize yourself.

Marketer

You ask ChatGPT for a brief, you get a wall of platitudes

The pain · "Write a marketing plan" returns 800 generic words. You spend more time re-prompting than writing.

The fix · PrePrompt adds the audience, channels, output format, and timeline you forgot. One Send instead of five.

What it sent

Plan a Q3 launch for a B2B SaaS. Audience: technical founders. 3 channels with 30-day actions, one metric to watch in week 4.

generic words

Founder

You context-switch between every chat all day

The pain · Half of every reply is wrong because you didn't say which company, which week, or what you've already tried.

The fix · Rewrites pull in the structure the model actually needs — without you re-typing the same setup five times.

Developer

Three-word prompts in Claude.ai aren't getting it done

The pain · "Fix this bug" gets you a generic answer that doesn't know your stack, your file, or your repro steps.

The fix · PrePrompt expands what you typed into a specific request — stack, file, repro, expected output. Same effort, real answer.

Student / researcher

Your prompts don't sound like the ones in the guides

The pain · You read "prompt engineering" advice and still don't know what to type. The blank box is the hardest part.

The fix · Every rewrite is a worked example. PrePrompt is the quietest tutor — you see what a good prompt looks like for your question.

Privacy

By default, only the prompt you choose to rewrite leaves your browser.

The extension does one thing on Send-click — POST your prompt to PrePrompt's rewriter and put the result back in the same textarea. Analytics events never include your prompt text; no DOM crawling, no surprise data trail.

Only your prompt leaves

By default, the extension sends one thing to PrePrompt: the text you typed into the chat box. Nothing from other tabs, nothing from your browser history. Conversation-aware mode (off unless you turn it on) also sends recent visible turns when enabled.

No background scraping

We don't read other tabs, conversation history, or anything outside the prompt textarea — even when you're on a supported site.

Stored only for your dashboard

Prompts that ran a rewrite show up on your dashboard. Sign out and they clear from your browser; delete your account and they're purged.

One outbound call. Same Anthropic API your IDE uses.

PrePrompt's rewriter calls the same Anthropic API your AI client already calls. We never proxy your prompt to a third-party log, ad network, or analytics layer.

Install

Install where you prompt. Keep prompting.

The Chrome extension is the front door. The VS Code extension is in private beta for devs who want the same rewriter inside their editor.

Questions

The eight we get the most.

PrePrompt is a free Chrome extension that rewrites your prompt before you hit Send on ChatGPT, Claude, Gemini, or Perplexity. You type as usual; the PrePrompt button next to Send replaces what you typed with a structured, specific version in about half a second. You then send the better one.
No. The rewrite goes into the same chat box you were already typing in. The LLM receives one prompt — the rewritten one — and treats it like any other message. PrePrompt is invisible at the model end.
Only the text in the chat textarea, sent when you click Rewrite — plus recent conversation turns only if you turn on conversation-aware mode (off by default). No other tabs, no DOM content outside the textarea, no browser data. Product analytics events never include your prompt text.
Yes — for your dashboard. Prompts that triggered a rewrite show up at preprompt.org/dashboard so you can see your usage and history. Sign out and they clear from the browser; delete your account and they are purged from our backend.
30 credits per month on the Free plan, no card needed. Developer ($12/mo) gets 500 credits/mo. Pro ($25/mo) gets 1,500 credits/mo; premium model access is coming soon. 1 credit = 1 standard Haiku rewrite. Local checks (pass-through, secret scan) never burn credits. The Free quota resets on the 1st of each month.
ChatGPT (chat.openai.com and chatgpt.com), Claude.ai, Gemini (gemini.google.com), and Perplexity. Each site has its own button injection — when one of them ships a UI change that breaks ours, we ship a fix in the extension's next release.
No subscription on those is required for PrePrompt to work. The free tier of each site is enough. PrePrompt itself is free for 30 rewrites/month and works the same whether you're on a paid or free tier of the LLM.
preprompt.org/dashboard shows your rewrites this month, your remaining quota, your plan, and a per-site breakdown. The Chrome extension auto-syncs to that same account.
