## SimmerDown

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.

- **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.

**Strengths:** Removes repetitive copy-paste from ChatGPT sessions; Custom commands make personal prompt patterns reusable; Free with no account or subscription required; Prompts and commands are stored locally on your device

**Limitations:** Very small user base and a single 0.0.1 release from 2023; Only works in Chrome together with the ChatGPT web interface; No team sharing, sync or analytics features

## Superhuman

Superhuman began as a famously fast email client and has expanded into a broader AI productivity suite. Today it spans Superhuman Go, an assistant that lives inside the apps and tabs you already use with inline suggestions and context-aware chat; Superhuman Mail, its email app with auto drafts, split inbox, auto labels, and auto archive; and Superhuman Docs, a collaborative workspace for documents, tables, data, and workflows.

A large part of the platform is built around agents. You can describe a task in chat or use a visual builder to create an agent, then share it with teammates or publish it to a company directory. Pre-built agents cover common knowledge-work jobs such as preparing for meetings by pulling relevant emails, notes, and docs, turning meeting notes into recaps for each owner, checking claims against company data, and humanising AI-generated text. Superhuman also sits inside the wider Superhuman Platform alongside Grammarly and GPTZero.

Superhuman is a paid product aimed at individuals, teams, and enterprises. The suite integrates with Gmail, Google Calendar, and many workplace tools, and the enterprise tier adds administration and security controls. For exact plan tiers, seat pricing, and included features, check the official pricing page, since packaging has changed significantly as the product has grown beyond email.
