AI Coding with Context Management·prompt.16x.engineer

16x Prompt is a desktop application that helps developers manage source code context and craft prompts for complex coding tasks on existing codebases. It generates optimized prompts from task instructions, source code files, and formatting instructions, which can be copied into ChatGPT/Claude or sent directly via API using multiple LLM providers. It includes features like code editing with visual diffs, prompt/context management, workspaces for multiple repositories, and token limit tracking.
