TokenLean

About

TokenLean compresses your prompts before they reach any LLM — cutting input tokens and controlling output tokens at the same time.

Most people focus only on what they type. But the real cost is in what the AI sends back. Output tokens cost 3–5x more than input tokens. TokenLean is the only tool that optimizes both sides.

HOW IT WORKS
──────────────────────────

1. Click the TL button on Claude.ai, ChatGPT, or Gemini
2. Your prompt is compressed instantly — bloated words swapped, filler removed
3. Compressed prompt is copied to clipboard
4. Paste and send — leaner prompt, tighter reply

Or use the popup:
→ Paste any prompt
→ Hit Compress
→ Copy the lean version
→ Paste anywhere

WHAT IT COMPRESSES
──────────────────────────

✦ Long words → short alternatives
   "implementation" → "build"
   "authentication" → "auth"
   "documentation" → "docs"
   "configuration" → "config"

✦ Filler phrases stripped
   "Could you please help me" → removed
   "I was wondering if you could" → removed
   "In order to" → "to"
   "As a result of" → "due to"

✦ Verbose patterns rewritten
   "I would like to know" → "tell me"
   "What is the best way to" → "best way to"
   "Due to the fact that" → "because"
