## Overview

SimmerDown targets a very specific friction point in daily ChatGPT use: the same long framing instruction you paste at the start of every conversation. Instead of retyping a paragraph of context, persona or style rules, the extension stores those instructions and inserts them when you type a short trigger such as !expert. The result is a faster, more consistent prompting routine.

The extension is deliberately small and simple. It is toggled on or off with a single switch, integrates quietly with the ChatGPT web interface, and covers a broad range of use cases, from demanding expert-level answers to enforcing a particular writing style or content format. Shorthand commands mean complex prompts become muscle memory rather than something you keep in a notes file.

Privacy is the design centerpiece: SimmerDown stores all pre-prompts and commands locally in the browser and does not send your data to external servers, and the developer's Chrome Web Store disclosure states that no data is collected or sold. It is a lightweight utility aimed at individuals who prompt ChatGPT often and want less repetition, not a team platform or analytics suite.

## Pricing & Plans

Listed as free on the Chrome Web Store. No subscription or paid tier is advertised.

## Key Features & Capabilities

- **Built-in pre-prompt library:** Comes with a set of modular, reusable commands you can drop into a ChatGPT question to steer the answer's detail and style.
- **Shorthand triggers:** Type a short code such as !expert to expand a full pre-prompt, replacing long manual copy-paste of instruction text.
- **Custom command creation:** Save your own recurring instructions as commands so personal prompt patterns are available in one keystroke.
- **One-switch enable/disable:** A simple toggle lets you switch the extension off when you want to prompt ChatGPT without any inserted text.
- **Local-only storage:** Pre-prompts and custom commands stay on your device; the extension does not phone home with your data.

## Primary Use Cases

- **Stop retyping the same setup prompt (Everyday ChatGPT user):** Save the context paragraph you paste into every chat as a command and insert it with a few characters instead.
- **Enforce a consistent tone (Writer or marketer):** Create style and formatting commands so drafts come back in the voice and structure you need on the first pass.
- **Request expert-level depth (Analyst or researcher):** Use a pre-prompt that nudges ChatGPT toward detailed, well-structured answers for technical or domain-specific questions.
- **Prompt without sending data out (Privacy-conscious user):** Keep your personal prompt library stored locally in the browser rather than in a third-party cloud account.
