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

PromptPlanner is a native Mac prompt manager that gives people who work with AI tools a single organized prompt library to hold the instructions that drive their work. Instead of digging through past chats or loose documents, you capture each useful prompt as a text card and drop it onto a board shaped around your projects. Every project sits in its own column with a goal and a running list of what is left, which keeps your intent and your next steps in view together. The daily rhythm stays light. You decide what needs doing, click a card to grab the prompt, paste it into whichever AI tool you prefer, and set the card aside once it is handled. When you want to pass along a richer context, you can export a full project as one instruction block that already carries the goal and the open items, which helps when you are briefing an assistant on a larger task. Because each project holds its own context, running several agents at the same time becomes far less messy.
