TokenLean for VS Code

Compress your AI prompts directly inside VS Code — before sending to GitHub Copilot, ChatGPT, Claude, or any LLM.

Why

Every word you send to an AI costs tokens. Long prompts = slow replies + higher API bills. TokenLean strips bloated words, filler phrases, and verbose patterns — same meaning, fewer tokens.

What it compresses

authentication → auth
documentation → docs
utilize → use
currently → now

Phrase stripping

Personal dictionary
