PromptLint

Description

Real-time prompt analysis in ChatGPT, Claude, Gemini and more. No AI, no network, offline. PromptLint is a privacy-first, local analysis tool designed to help developers, prompt engineers, and AI users write clearer, more effective prompts before sending them to Large Language Models (LLMs). Instead of using another cloud-based AI to rewrite your text—which introduces latency, privacy risks, and extra costs—PromptLint acts like a traditional code linter (such as ESLint) directly inside your browser. It analyzes your text locally in real time and highlights potential issues before you hit send. Key Features and Analysis Capabilities: • Ambiguity & Conflict Detection: Spot vague phrasing, missing constraints, or contradictory instructions before they lead to poor AI responses. • Quality & Context Suggestions: Ensure your prompt contains sufficient context, clear formatting, and structured instructions. • Spelling & Grammar Corrections: Catch typos, grammatical errors, and accidental repeated words instantly. • Provider Agnostic: Designed to work seamlessly across popular web-based AI platforms, including ChatGPT, Claude, Gemini, and custom AI chat interfaces. 100% Private and Offline: • No External Servers: All text analysis runs completely offline in your browser. Your prompts are never transmitted, stored, or processed on remote servers. • Zero Telemetry: PromptLint does not collect analytics, track user browsing behavior, or store personal information. • Lightweight & Fast: Get instant feedback without slowing down your workflow or waiting for API responses. How It Works: 1. Open your preferred AI assistant in your browser (e.g., ChatGPT, Claude, Gemini). 2. Type your prompt in the input box as you normally do. 3. PromptLint analyzes the text in real time and provides clean, actionable suggestions right inside your browser window. Improve your AI workflow, avoid wasted tokens, and get better AI results on the first try with PromptLint.
