What It Does

16x Prompt is a desktop application that helps developers manage source code context and create structured prompts for complex coding tasks on existing codebases. It bridges the gap between your local development environment and AI language models like ChatGPT, Claude, and Gemini by intelligently preparing and optimizing prompts with relevant code context.

Who It's For

Designed for professional developers, consultants, and agencies working with AI-assisted coding workflows. Whether you're refactoring legacy code, building new features, or maintaining multiple projects, 16x Prompt helps you work more efficiently with AI coding assistants. Already trusted by 10,000+ users from tech companies, consulting firms, and development agencies.

Key Features & Capabilities

• Context Management: Select and organize relevant source code files, manage multiple repositories through workspaces, and keep context within LLM token limits with built-in tracking • Code Editing & Diff Viewing: Automatically apply AI-generated code changes with visual diffs, automatic backups, and reversible edits for safe experimentation • Multi-Provider API Integration: Connect with OpenAI, Anthropic Claude, Google Gemini, DeepSeek, OpenRouter, Ollama, Azure OpenAI, and any OpenAI-compatible API using your own keys (BYOK) • Model Comparison: Run prompts against multiple LLM models side-by-side to identify the best performer for your specific use case • Prompt Customization: Save reusable task instructions for common operations (refactoring, documentation, new features), create custom instructions per tech stack, and fine-tune optimization settings • Local Privacy: Works entirely offline with local data processing—copy prompts to paste into ChatGPT/Claude UI or self-hosted LLMs for complete privacy control

Typical Workflow

Developers use 16x Prompt to structure their AI coding workflow: organize projects in workspaces, select relevant source files, add task instructions, and generate optimized prompts with proper formatting. The app automatically optimizes code context and tracks token usage. You can either copy the final prompt to paste into ChatGPT Plus/Claude Pro subscriptions, or send directly via API integration. The new code edit feature then applies changes with visual diffs and automatic rollback capability.

What Makes It Different

Unlike cloud-based coding assistants, 16x Prompt runs entirely on your local machine, giving you full control over data privacy and the ability to work offline. It's transparent (no black box), supports all major programming languages and frameworks (Python, JavaScript, TypeScript, React, Next.js, Django, etc.), and works with your existing LLM subscriptions or API keys. The workspace system uniquely handles multi-repository projects, while the model comparison feature helps teams identify cost-effective LLM choices.
