AI Context Optimizer NO API KEY
Compress your code before sending to ChatGPT, Claude, or Gemini. Strips comments, blank lines, and debug statements to save tokens and money. Auto-masks secrets so your API keys never leak. 100% browser-based — no server, no API key, no signup.
Why Optimize Code Before Sending to AI? A Complete Guide to Saving Tokens and Money
AI coding assistants like ChatGPT (GPT-4o), Claude, Gemini, and GitHub Copilot have transformed how developers write software. But there is a hidden cost: every character you send to an AI model consumes tokens, and tokens cost money. A single API call with 3,000 lines of unoptimized code can cost $0.10-$0.50 depending on the model. If you are making hundreds of calls per day, that adds up quickly to hundreds of dollars per month.
The problem? Most code is full of information that wastes tokens without helping the AI understand your problem. Comments explaining what the code does (the AI can read the code itself), blank lines for visual spacing, debug statements like console.log, trailing whitespace, and lengthy import blocks for well-known libraries all consume tokens without adding useful context.
Our AI Context Optimizer strips all of this out in one click, typically reducing token usage by 20-40%. That translates directly to cost savings, faster responses, and the ability to fit more relevant code into the AI's context window.
How This Tool Works (No API Key Required)
This tool runs 100% in your browser using client-side JavaScript. When you paste your code and click Optimize, the following happens entirely on your device:
- Comment Removal — Regular expressions detect and strip single-line comments (
//), multi-line comments (/* ... */), Python/shell comments (#), and HTML comments (<!-- -->). Shebangs (#!/usr/bin/env) and hex color codes (#FF0000) are preserved. - Debug Statement Removal — All
console.log(),console.warn(),console.error(),console.debug(),console.info(),console.trace(), andconsole.table()calls are stripped. - Whitespace Optimization — Trailing spaces and tabs are removed from each line. Multiple consecutive blank lines are collapsed into a single line break.
- Secret Masking — Pattern-matching detects and replaces sensitive data before you even see the output. No secrets ever leave your browser.
- Token Estimation — A BPE-like heuristic counts tokens locally by splitting code into words, operators, and identifiers, then estimating based on average code token sizes (~3.5 characters per token).
No data is ever transmitted to any server. You can verify this by opening your browser's Network tab (F12) and watching for zero outgoing requests while using the tool. This makes it safe to process proprietary code, credentials, and internal business logic.
Security: Automatic Secret Detection and Masking
Accidentally leaking API keys, database credentials, or authentication tokens to AI services is one of the most dangerous security risks in the age of AI-assisted development. Our masker automatically detects and replaces these common patterns:
- OpenAI / Anthropic API Keys: Patterns starting with
sk-followed by 20+ alphanumeric characters - Stripe Keys:
pk_live_,pk_test_,rk_live_,rk_test_patterns - AWS Access Keys:
AKIAprefix followed by 16 uppercase alphanumeric characters - JWT Tokens: Base64-encoded tokens matching
eyJ...eyJ...signatureformat - Environment Variables: Values assigned to variables named
SECRET,PASSWORD,API_KEY,PRIVATE_KEY,ACCESS_TOKEN, etc. - Bearer Tokens:

Understanding AI Tokens: How Pricing Works in 2026
A token is the basic unit AI models use to process text. For source code, the ratio is closer to 3-3.5 characters per token because code contains many short symbols and keywords.
Current pricing examples (as of 2026):
- GPT-4o: $2.50 per 1M input tokens, $10.00 per 1M output tokens
- Claude Sonnet: $3.00 per 1M input tokens, $15.00 per 1M output tokens
- Gemini 1.5 Pro: $1.25 per 1M input tokens, $5.00 per 1M output tokens
Advanced Prompt Engineering Tips for Developers
- Remove Import Statements for Standard Libraries — AI models already know popular packages. Remove import blocks to save 10-15% of tokens.
- Replace Large Data Literals — Instead of sending a 500-element array, describe the structure.
- Focus Your Context — Only send the file(s) relevant to your question.
- Use Context Windows Efficiently — Shorter context = faster and more accurate responses.
- Wrap Code in Markdown Blocks — Always wrap code in triple backticks with language hints.
Supported Languages
Our comment removal engine works with code written in JavaScript, TypeScript, Python, Java, C, C++, Go, Rust, PHP, Ruby, Swift, Kotlin, and any language that uses //, /* */, or # comment syntax. HTML/XML comment removal (<!-- -->) is also supported.
