Key Features

Prompt Management

Structured Prompt Creation for Coding

16x Prompt helps developers manage source code context and craft prompts for complex coding tasks on existing codebases. This feature allows users to create structured prompts that incorporate relevant context, making it easier to generate accurate code outputs.

Prompt Management

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. This feature streamlines the coding process by allowing users to quickly access and utilize their frequently used prompts.

Custom Instructions & Prompt Customization

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, ensuring that the generated code meets specific requirements.

Code Editing

🔥 Code Edit: Apply Code Changes Safely

Automatically apply code changes with our new code edit feature, powered by the latest AI models. View visual diffs of the changes made, ensuring that every modification is transparent and reversible, allowing users to code with confidence.

Compare LLM Responses

When using API, you can compare the code output of different LLM models (for example, GPT-4.1 vs Gemini 2.5 Pro) side-by-side to see which one is the best for your use case. This feature helps users make informed decisions about which model to use based on performance.

Integration & API

BYOK API Integrations

16x Prompt supports API integrations with providers like OpenAI, Anthropic Claude, Google Gemini, and more. Users can bring their own API keys to connect with these services, allowing for flexibility in choosing the best AI model for their coding tasks.

Token Limit Tracking

Keep your prompt within LLM's token limit with the built-in token limit counter. This feature ensures that users do not exceed the limitations set by the AI models, preventing errors during prompt submission.

Local Data Privacy

The app works locally without an Internet connection. You can copy-paste the final prompt into LLMs running locally to protect your privacy. This feature ensures that sensitive data remains secure and is not transmitted over the internet.

User Experience

Formatting Instructions

The app automatically adds optimal formatting instructions to the prompt to generate ready-to-use code. Users can also create custom formatting instructions for different use cases, enhancing the usability of the generated code.

Workspaces

Organize your source code context using workspaces to manage multiple repositories and projects in one place. This feature allows users to switch between different projects easily, improving workflow efficiency.
