## Overview
16x Prompt is a developer-focused tool designed to streamline AI-assisted coding workflows by managing source code context and crafting optimized prompts for complex coding tasks. It helps developers prepare codebases for large language models like ChatGPT, Claude, and Gemini by automatically formatting code, tracking token limits, and generating ready-to-use prompts that can be copied directly or sent via API. The tool distinguishes itself through local-first privacy (works without internet), support for multiple LLM providers, visual diff application of code changes, and the ability to compare outputs from different models side-by-side. One limitation is that users need to provide their own API keys or existing subscriptions to LLM services; the tool itself does not include API access.
## Key Features
- Structured prompt creation for coding
- Code context management with file selection
- Custom instructions and prompt customization
- Token limit tracking with counter
- API integrations with multiple LLM providers
- Code editing with automatic visual diffs
- Comparison of LLM responses side-by-side
- Prompt management and reusable task templates
- Workspace organization for multiple projects
- Local-first architecture (works offline)
- Support for ChatGPT Plus and Claude Pro subscriptions
- Automatic code change application and rollback

## Use Cases
- Refactoring existing codebases with AI assistance
- Creating new features or pages with AI guidance
- Writing documentation for code projects
- Comparing outputs from different LLM models for coding tasks
- Managing multiple repositories and projects in organized workspaces

## Who It Is For
- Software developers working with existing codebases
- Tech companies seeking to optimize AI coding workflows
- Consulting firms using AI for client projects
- Development agencies integrating AI tools
- Engineers doing prompt engineering or model evaluation

## Pros
- Works locally without internet connection, enabling offline privacy for sensitive source code
- Supports multiple LLM providers (OpenAI, Claude, Gemini, DeepSeek, Ollama, etc.) allowing flexibility and cost comparison
- Visual code diffs with automatic rollback reduce risk when applying AI-generated changes
- Token limit tracking prevents costly API errors or incomplete responses from LLM APIs

## Cons
- Requires users to provide their own API keys or subscriptions; no included LLM access
- Plugin/extension availability appears limited compared to full IDE integrations like Cursor
- Relies on users bringing their own LLM credentials rather than integrated subscriptions
