You can either copy the final prompt, or send it via API (bring your own API key).
16x Prompt supports API integrations with providers like OpenAI, Anthropic Claude, Google Gemini, DeepSeek, OpenRouter, Ollama, Azure OpenAI.
We also support any other providers that offers OpenAI API compatibility, such as Fireworks, Hyperbolic, DeepInfra, etc.
Check out our DeepSeek R1 provider comparison if you are looking for a provider for self-hosting DeepSeek models.
When using API, you can compare the code output of different LLM models (for example, GPT-4o & Claude 3.7 Sonnet) side-by-side to see which one is the best for your use case.
Save your commonly used prompts such as refactoring, creating a new page, writing docs and other repetitive tasks as task instructions to reuse them later.
Craft and save your 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, for example, a landing page, a blog, and a web app.
You can also include multiple repositories in a single workspace to work on related projects, for example, a frontend and backend repository that are part of the same project.

The tool you've created is extremely helpful and I bought it "sight unseen" given its price.

Although my prompt engineer is pretty similar but yours reduces the copy paste hassle as i can just drag and drop the file.
