Wristla - Tesla AI Assistant

Drive with Wristla, extend your Tesla's life.

Daily use of Wristla is associated with a 12% improvement in driving efficiency within the first month, measurably slower battery degradation through optimised charging habits, and early detection of irregularities in your vehicle's behaviour. Users report smoother driving patterns, better energy management and a clearer understanding of their car's condition.*

Daily Efficiency Score

Every trip and charge session is scored across 40+ telemetry metrics. At the end of each day you get a summary with a composite efficiency score, style breakdown and specific insights for your car.

58 / 100

Telemetry Factors

Acceleration 55
Smooth launches reduce inverter, tire and aero losses.
Max Speed 62
Aerodynamic drag rises rapidly with speed - short bursts at high speed cost disproportionately more energy.
Avg Speed 58
Scored per context: city, mixed or highway. Each context has its own efficient band.
Regen Ratio 56
How much energy was recovered through regenerative braking instead of wasted on friction braking.
Braking 52
Late or aggressive braking wastes momentum that could have been carried forward or recovered through regen.
Preconditioning 64
Preparing the battery and cabin before driving avoids expensive warm-up mid-trip.
Tire Pressure 62
Low pressure increases rolling resistance, so the car uses more energy at the same speed.

Daily Insights

Green Streak Consecutive days with efficiency score above 75/100. Resets on any yellow or red day.
Vs Norm Compares your actual energy use against a personal baseline for the same driving conditions.
Est. Savings When you use less energy than baseline, the kWh difference is your estimated saving - daily and weekly.
Trend Compares 7-day vs 30-day average Wh/km. Shows if you are improving, stable or declining.

The system calibrates to your personal driving profile over 7-30 days. Every comparison uses your own rolling baseline by context and temperature - not fixed industry averages.

Pace of Aging

How fast your car is aging relative to normal. A pace of 1.0x means standard aging. Below 1.0x - you are taking excellent care. Above 1.0x - harsh usage is accelerating wear. Based on 5 health components measured over a 30-day rolling window.

Health Components

Battery Health 60
Tracks range retention over time. Compares degradation rate against the expected 2.5% per year for your model.
Driving Style 55
30-day average of acceleration, braking and max speed scores. Aggressive driving accelerates wear on tires, brakes, suspension and battery pack.
Charging Habits 58
DC fast charging ratio vs AC home charging, and average battery level at end of charge. Mostly home charging to 80% or less is ideal.
Efficiency 50
30-day rolling average of your daily efficiency score. Higher efficiency correlates with gentler drivetrain use and better maintenance.
Climate Stress 54
Tracks days with extreme temperatures (below -5C or above 40C) and whether you used battery preconditioning.

Measured from real charge cycles, not the estimated range on your dashboard. The system needs at least 7 days of data to begin tracking and grows more accurate over time.

Personal Tesla Assistant

An AI chat that knows your car - full trip and charge history, live telemetry, alerts and error logs, and the official Tesla owner's manual for your model.

Why was my energy consumption higher on Tuesday's commute?
AI analyst
Tuesday's commute used 18.4 kWh/100km vs your usual 14.7. Main factors: temperature dropped to −3°C (+2.1 kWh for cabin heating), tire pressure was 2.6 bar (below your 2.9 baseline), and average speed was 12% higher due to highway rerouting. Adjusting tire pressure alone could save ~8% on similar routes.

Trip Analytics

Every trip is automatically detected and scored across all 7 efficiency factors plus driving style. You get a complete breakdown - what went well, what cost extra energy, and why.

Trip Efficiency 56
Composite score from all 7 telemetry factors for this specific trip.
Driving Style 62
Combines hard acceleration, hard braking, high speed and sharp cornering into a single 0-100 score.
Vs Norm 52
Compares measured trip energy against the expected baseline for a trip of similar distance and driving context.

Trips are detected from Tesla Fleet Telemetry in real time. Each session is scored against your personal 30-day rolling baseline by context (city, mixed, highway) and temperature.

Charge Analytics

Every charge session is tracked with full detail - energy added, cost, peak rate, efficiency and optimisation insights. Supercharger and home charging, all in one place.

Charge Scoring

Charge Target 60
Charging above 80% without trip-planner context adds unnecessary time and battery stress.
Cold Pack Start 56
If the battery was still heating when charging began, some energy was spent warming instead of charging.
Preconditioning 64
Battery preconditioning detected before this charge - reduces thermal stress and improves charge speed.
Charge Efficiency 58
Composite score factoring charge target, pack temperature and preconditioning behaviour.

Matched with Tesla billing data when available. The system tracks your DC/AC charging ratio and average end-of-charge level over time to flag habits that accelerate degradation.
