Horizon for Claude — Usage Limit Monitor

Horizon helps Claude users understand their 5-hour and weekly usage limits, reset times, current pace, and projected usage directly on Claude.ai. Instead of showing only percentages, Horizon turns available usage readings into clear dashboards, countdowns, progress indicators, and forecasts that help you plan your work before the next reset. Choose the layout that fits your workspace: • a horizontal bar integrated near the Claude message area; • a compact bottom mini bar for smaller laptop screens; • a vertical bar positioned along the side of the page; • a movable floating layout; • an optional Chrome side panel for a broader overview. The Decision First view makes the most important information easier to understand by showing what is expected to happen sooner — a reset or reaching the projected limit. Main features: • 5-hour and weekly usage overview; • reset countdowns and clear timelines; • usage pace and exhaustion forecasts; • progress indicators for both limit windows; • horizontal, vertical, mini, and floating layouts; • movable and configurable interface elements; • local and synchronized statistics across Chrome devices; • optional usage alerts and configurable thresholds; • light, dark, and automatic themes; • interface scale and positioning controls; • English and Polish language support; • local data management, including deletion of stored readings and forecasts. Horizon is designed to remain visible when useful and compact when you need more workspace. The interface can be adjusted to match large desktop monitors as well as smaller laptop screens. Privacy: • Horizon does not read or store the content of your Claude conversations; • no Claude or Anthropic API key is required; • usage data and preferences are stored using Chrome extension storage; • stored local data can be removed from the extension settings. Horizon is free to use. Independent extension. Not affiliated with or endorsed by Anthropic.
