LLM Text Summarizer is a Chrome extension that uses advanced AI from OpenAI to produce high-quality summaries of selected text. Users can simply select the text they want summarized, right-click, and choose 'Summarize' from the context menu. The extension processes the text with OpenAI's API and provides a concise summary in a modal window. The summary can be easily copied to the clipboard, and the tool supports Markdown for better readability. It is customizable with personal OpenAI API keys.

TokenCounter is a user-friendly tool designed to estimate the number of tokens and the corresponding costs for various AI models, including those from OpenAI and Anthropic. The tool supports multiple languages and provides real-time token counts as users input their text. TokenCounter is particularly useful for developers and businesses working with language models, allowing them to manage API costs, optimize inputs, and avoid exceeding model limits. Accurate estimation is achieved by using the tiktoken library for OpenAI models and an older method for Anthropic models, with plans to update as new information becomes available.
