Description
AI-powered writing assistant that improves social posts, emails, and professional content using user-provided AI API keys. PromptSmith is a Chrome extension that transforms any web-based text editor into a context-aware AI writing assistant — while keeping you in full control of your data and API keys. Unlike traditional AI writing tools that send raw text directly to a model, PromptSmith runs a 5-stage local analysis pipeline before generating a request. It evaluates tone, readability, platform context, content structure, and writing behavior to build a precise brief for the AI — so the output is actually relevant, not generic. How it works Most AI writing tools do one thing: take your text and pass it to a model. PromptSmith does five things first. It reads your linguistic signals, detects the platform context, analyzes your typing behavior, fuses all three into a signal object, and only then constructs the prompt. The AI receives a precise recipe, not a vague instruction. Key Features Context-Aware Enhancement Local analysis of your draft runs before any AI request is made, producing more relevant and higher-quality suggestions. Bring Your Own API Key Connect your own account with any supported AI provider. You choose the service, you control the cost, you own the relationship. Inline Suggestions Suggestions appear directly inside the editor you are already using. Accept with Tab, dismiss with Esc. Style Memory PromptSmith learns from every edit you accept, storing examples locally in your browser. Over time suggestions sound more like you and less like a generic AI. Works Everywhere You Write Compatible with social platforms, email clients, AI chat interfaces, note-taking tools, and any website with a standard text editor. Privacy by Design All analysis runs locally. Your content is never transmitted until you explicitly request a suggestion. Your API key is encrypted with AES-256 and never leaves your device. Who is it for PromptSmith is designed for professionals, creators, students, and anyone who wants AI writing assistance without giving up control over their data, their keys, or their voice.
