A live gauge of your AI chat's remaining context
Headroom is an innovative open-source tool designed to provide users with a real-time gauge of their AI chat's remaining context. Built to address a common challenge in AI interactions—losing track of conversation history—Headroom helps users avoid unexpected forgetfulness by visually indicating how many tokens are left before the AI starts to forget earlier parts of the dialogue. It's particularly valuable for developers, researchers, and power users who rely on long, complex prompts and want to optimize their AI usage without the risk of losing critical context. Unlike many platforms that lack transparency into token limits, Headroom reads, counts, and discards text locally, ensuring privacy and no need for API keys or server calls. This makes it a lightweight, secure, and accessible tool for those working with models like ChatGPT, Gemini, and others, especially in environments emphasizing open source and customization.
