Claude Fable 5 Limit & Usage Tracker | Burn-Rate ETA - LimitLens

LIMITLENS!!! See your Claude limits at a glance — live session gauge, weekly caps, burn-rate ETA and a peak-hour advisor. 100% local & private. Know exactly how much Claude you have left — before you hit the wall. 🎯 LimitLens puts your Claude AI usage one click away from any tab: your 5-hour session, your 7-day weekly limits, and — unlike any other tracker — a prediction of WHEN you'll hit your cap at your current pace. Stop guessing. Stop getting cut off mid-prompt. Free. Local-first. No account needed. 🔮 BURN-RATE ETA — THE FEATURE NOBODY ELSE HAS Other trackers tell you "you've used 63%." LimitLens tells you what that actually means: ⏰ "At this pace, cap hits ~4:42 PM" 📈 Your live burn rate in %/hour (turns red when you're going too fast) 🔄 Exact countdown to your next session and weekly reset It samples your usage over time and does the math for you — so you can decide whether to push on or take a break. ⏱️ LIVE SESSION GAUGE A beautiful instrument-style dial with tick marks and a moving needle shows your 5-hour session at a glance. The arc fills smoothly and shifts color as you approach your limit: 🟢 Green — cruise mode 🟡 Yellow — halfway there 🟠 Orange — slow down 🔴 Red — danger zone 📊 7-DAY LIMITS, PER MODEL Track your weekly cap across All models, with a highlighted bar for Anthropic's newest flagship model so you always know how much of it you have left this week. Each model gets its own animated usage bar. ⚡ PEAK-HOUR ADVISOR Peak hours drain your session several times faster. LimitLens shows a live peak/off-peak banner with a ticking countdown to the next change — so you can shift heavy work to off-peak windows and get more out of every session. 🕐 🔔 SMART ALERTS (OFF BY DEFAULT) Optional browser notifications at 75%, 90% and 100% of your session. No nagging — they're off until you turn them on, and you can switch them off anytime with one click. 🗓️ ACTIVITY HEATMAP A GitHub-style grid shows when you actually use Claude — hour by hour across the week, or day by day across the month. Spot your patterns. Plan around peak. Work smarter. 📅 👀 ALWAYS-ON TOOLBAR ICON Two concentric rings live on the icon itself: ⭕ Outer ring — your 5-hour session ⭕ Inner ring — your 7-day weekly limit Plus a live percentage badge, color-coded from green to red.
