SwissKnife AI

Your AI Swiss knife — timestamps, writing rules, and more.

SwissKnife AI - Take control of how ChatGPT, Claude, and Gemini respond to you Tired of AI chatbots that ramble, overuse em dashes, bury the point in bullet lists, or just won't write the way you actually want? SwissKnife AI gives you a simple control panel that sits on top of ChatGPT, Claude, and Gemini, letting you set writing preferences once and have them respected for the rest of your conversation. Writing Rules, Your Way Pick from a set of ready-made rules - no em dashes, no bullet points, concise responses only, plain English, no jargon, short paragraphs - or write your own custom rules in plain language. Check the boxes for whatever you want enforced, hit Inject, and the extension sends a natural instruction to the AI on your behalf. No more repeating yourself every single chat. Each rule shows a clear "active" tag once it's been applied to the current conversation, so you always know exactly what's currently in effect. Changed your mind? Uncheck everything and inject again to reset the AI back to its normal writing style. Built-In Conversation Search Long AI conversations get messy fast. SwissKnife AI adds a real search bar right inside the extension popup - type a word, hit enter, and jump straight to where it appears in your conversation. The matching text is highlighted clearly so you never lose your place, and previous/next buttons let you step through every occurrence without manually scrolling through hundreds of messages. Know Exactly When You Said What SwissKnife AI automatically stamps your messages with the current date, time, and timezone before they're sent - so the AI always knows exactly when you're writing from, which matters more than you'd think for anything time-sensitive (deadlines, "what's today's date," scheduling, recent events). Toggle it on or off anytime from the popup. Works Where You Work SwissKnife AI runs quietly in the background across ChatGPT, Claude, and Gemini. No accounts, no setup wizards, no nonsense - install it, open any of those chat platforms, and the toolbar icon gives you everything you need in one click. Privacy First SwissKnife AI doesn't collect, store, or transmit your conversations anywhere. Your rules and preferences are saved locally using Chrome's built-in sync storage, so they follow you between devices if you're signed into Chrome, but they never leave your browser through us. There's no analytics, no tracking, no third-party servers involved in how the extension functions. Why People Use It If you've ever found yourself typing "please don't use bullet points" or "keep it short" at the start of every single message, this extension exists so you never have to do that again. If you've ever lost track of something an AI said three days into a long conversation, the search feature gets you back to it in seconds. It's a small tool that fixes two very specific, very real annoyances - nothing bloated, nothing you don't need. What's Included Custom and prebuilt writing rule presets with one-click apply. Per-conversation tracking of which rules are currently active. In-page conversation search with highlight and step-through navigation. Automatic timestamp injection with full date, time, and timezone. A simple on/off toggle if you ever want to pause the extension entirely. Support for ChatGPT, Claude, and Gemini, with more platforms planned. A Note From the Developer SwissKnife AI is built and maintained by a solo developer who got tired of fighting with AI chat formatting and built the fix. If something breaks or you've got an idea for a feature that would genuinely help, feedback is always welcome - this extension grows based on what people actually need, not speculative features nobody asked for.
