What is 16x Prompt?
16x Prompt is an advanced AI coding tool designed to supercharge your development workflow by providing sophisticated context management and prompt optimization. It enables developers to select relevant source code context, craft precise prompts, and send them to multiple large language models (LLMs) via API integrations, including OpenAI, Anthropic Claude, Google Gemini, DeepSeek, OpenRouter, Ollama, and Azure OpenAI. The tool supports any provider offering OpenAI API compatibility, such as Fireworks, Hyperbolic, and DeepInfra.
Key features include a powerful code editing capability that automatically applies changes with visual diffs, ensuring every modification is reversible and backed up for confidence. You can compare outputs from different models side-by-side (e.g., GPT-4.1 vs. Gemini 2.5 Pro) to determine the best fit for your task. Save frequently used prompts as reusable task instructions for activities like refactoring, creating new pages, or writing documentation. Custom instructions can be tailored to specific tech stacks like Next.js, Python, or SQL, and prompt optimization settings help fine-tune results.
Workspaces allow you to organize source code context across multiple repositories and projects, switching seamlessly between them. You can even include multiple repositories in a single workspace for related projects, such as a frontend and backend repository. Token limit tracking ensures you stay within model constraints, and you can either copy the final prompt or send it directly via API using your own API key—no black box.
With over 10,000 users from tech, consulting, and agencies, 16x Prompt helps you ship quality code faster by managing complex coding tasks on existing codebases. Whether you are refactoring legacy code, adding new features, or integrating multiple services, this tool streamlines your AI coding workflow, making it an essential asset for any developer looking to leverage LLMs effectively.
