The extension features 'Smart Paste' to automatically format copied tables into Markdown and create links from selected text and URLs. It also implements bidirectional scrolling synchronization between the editor and preview panes and includes a 'Document X-Ray' feature to estimate LLM token counts for documents. AI

LLM Token Counting and Cost Optimization: A Practical Guide

This guide explains how to manage costs associated with using large language models by focusing on token counting and optimization. It details that tokens are text chunks generated by a tokenizer, not simply words or characters, and that providers often charge more for output tokens than input tokens. The article recommends using libraries like `tiktoken` to count tokens accurately before API calls and implementing strategies such as prompt compression and hard output caps to reduce unnecessary token usage and control expenses.
