bctx — Token Compression

Compress pasted content before sending to AI tools. Reduces token consumption by up to 90% on paste and send.

better-ctx automatically compresses your prompts before they reach the AI — saving up to 99% of tokens on every message. When you paste code, error logs, or long context into an AI chat tool, most of it is noise: blank lines, comments, boilerplate, repeated patterns. better-ctx strips it down to pure signal before the message is sent — so the AI gets less clutter and you spend fewer tokens. HOW IT WORKS ──────────── 1. You type or paste your prompt as normal 2. When you hit Send, better-ctx intercepts it 3. Compresses the text using AST-aware patterns 4. Shows you the savings: "1,200 → 180 tokens (-85%)" 5. Sends the compressed message automatically NO CHANGES TO YOUR WORKFLOW ──────────────────────────── Works silently in the background. No new UI to learn. Just cheaper, faster AI interactions.

Compression happens locally — either in the browser or via the locally installed binary on your machine.
