About

Manage source code context and generate optimized prompts. Ship with ChatGPT and Claude. 16x Prompt helps developers manage source code context and prompts to complete complex coding tasks on existing codebases. Enter your own API key to use APIs from OpenAI, Anthropic, Azure OpenAI, OpenRouter, or 3rd party services that offer OpenAI API compatibility, such as Ollama and OxyAPI. Using API avoids leaking your code to OpenAI or Anthropic training data. Compare the code output of different LLM models (for example, GPT-4o & Claude 3.5 Sonnet) side-by-side to see which one is the best for your use case. Craft and save your best prompts as task instructions or custom instructions to use across different tech stacks like Next.js, Python, and SQL. Fine-tune your prompt with various optimization settings to get the best results. Organize your source code context using workspaces to manage multiple repositories and projects in one place and switch between them easily.

About

PromptMason is a desktop application for organizing reusable prompts and building them from shared text blocks. Users can create blocks for roles, background, tasks and formats, then update a block once to revise every dynamic prompt that uses it. The app includes prompt search, fill-in variables, AI-assisted rewriting, prompt evaluation, and privacy checks that flag sensitive information. Its optional local AI model can run on the user’s computer without sending prompt text to a cloud AI provider. Built-in MCP connections let Claude Desktop, Cursor and Claude Code search, fill and save prompt-library content. Users can also access prompts through a Chrome extension, share libraries using their own cloud-storage folders or a network drive, and manage Markdown documents and downloadable AI Skills. A free plan includes all features with limits of 25 blocks and 15 prompts; Pro removes those limits.
