16x Prompt

verifiedFreemiumAPI16x.engineer

Local desktop app that assembles code-context prompts for LLMs, with API integrations, token tracking, and prompt saving.

What it does

16x Prompt is a desktop application that helps developers craft prompts for coding tasks on existing codebases. It manages source-code context and custom instructions, then lets you copy the final prompt or send it via your own API key to providers like OpenAI, Claude, and Gemini. Prompt generation runs locally for privacy, with token tracking and a new code-edit feature.

How to use: Users enter instructions, select source code files, and the app generates a final prompt. This prompt can then be copied and pasted into ChatGPT, Claude, or DeepSeek. The app automatically adds optimal formatting instructions and optimizes the source code and prompt for best results.
