GPT-5, Claude 4, and Windsurf Optimized
Sanitize text before sending to AI. Removes PII, API keys, URLs, code comments, and estimates token count.
Prepare text for AI summarization. Remove noise, format structure, estimate tokens, and generate optimal summarization prompts.
Prepare code snippets for AI explanation. Strip sensitive data, add context markers, detect language, and generate explanation prompts.
Describe what you want to match in plain English and get an optimized prompt for AI to generate the perfect regex pattern.
Paste your git diff and generate optimized prompts for AI to write conventional commit messages. Supports conventional commits format.
Extract TODO, FIXME, HACK, and NOTE comments from code. Generate AI prompts to prioritize and resolve them.
Count tokens for GPT-4, Claude, Gemini & Llama. See cost estimates per model. 100% client-side BPE estimation.
Check if your prompt fits GPT-4, Claude, Gemini context windows. Estimate tokens, usage %, and API costs per model.
Paste a git diff, choose review focus (security, performance, bugs), get a structured prompt for AI code review.
Paste JSON, choose a mode (analyze, transform, validate, document, mock), get a structured AI prompt instantly.
Fill in project details, pick a style (minimal, detailed, badges, startup), get a polished AI prompt for README.md generation.
Compare API costs across GPT-4, Claude, Gemini, Llama, DeepSeek & more. Estimate per-request, daily, and monthly expenses.
Paste code, choose review type (security, performance, refactor), get expert-level AI prompts optimized for reasoning models like GPT-5.
Refine your system prompts for GPT-5, Claude 4, and Gemini. Version your prompt templates and optimize for token efficiency.
Design robust, resilient system instructions for AI agents. Optimized for GPT-5 and Claude 4 Opus instructions.
Transform code logic or text descriptions into Mermaid.js diagrams using AI-optimized prompts. Visualize system flows instantly.
Visualize context window usage and calculate projected API costs for GPT-5, Claude 4, and reasoning-first models.
Visualize and audit complex 'Chain of Thought' logs from reasoning models like GPT-5 and Claude 4. Detect hallucinations and logic fragility instantly.
Programmatically strip comments, boilerplate, and logs to reduce token usage in LLMs. Optimized for Cursor, Windsurf, and Claude Pro limits.
Secure and optimize your data before sending it to AI agents. Redact PII, hide API keys, and compress code to save 30% on token costs. 100% private, client-side only.
Instantly generate optimized .cursorrules files for Cursor AI and Windsurf. Fine-tune your AI agent with project-specific coding standards, architectural patterns, and style guides.
The AI Passport is a standardized framework for developers to safely interact with Large Language Models. It defines the protocols for data sanitization, context window management, and system role architecture.
