Horizon for Claude — Usage Limit Monitor Chrome extension security report

Horizon AI helps Claude users understand their active 5-hour and weekly usage limits, reset times, and current pace. Instead of showing only a percentage, Horizon AI turns the available Claude usage readings into clear dashboards, countdowns, local history, and forecasts that help you plan work before the next reset. Main features: • live 5-hour and 7-day usage views; • reset countdowns and “what happens first?” timelines; • pace and exhaustion forecasts based on real readings; • optional alerts when usage approaches a selected threshold; • local Chronicle / Flightboard history and forecast accuracy; • popup, Chrome side panel, and optional on-page Edge Beacon / Horizon Deck; • light, dark, and automatic themes; • English and Polish interface; • local data controls, including deletion of stored readings and forecasts. Privacy: Horizon AI does not read conversation content or prompts. Usage readings, history, and forecasts are stored locally in Chrome. No analytics or advertising telemetry is included. Preview release: Horizon AI is actively developed. Interface details and compatibility may change as Claude evolves. Horizon AI is an independent, unofficial extension developed under the Kiewik Projects brand. It is not affiliated with, endorsed by, or produced by Anthropic. Horizon AI monitors limits; it does not increase, bypass, or modify them.
