Interactive math, coding and AI tutoring you learn by doing
Learn math, science, CS and AI through short, visual exercises that build intuition step by step rather than passive video watching.
A visual, interactive tutor that works on a shared canvas, asks guiding questions and gives hints without simply revealing the answer.
Quizzes and reviews adapt to your level, tracking what you have mastered and resurfacing topics that still need work.
Write and run real code to learn programming logic, algorithms, data structures and debugging skills relevant to the AI era.
A clear yes, caution or no answer for going outside today
Instead of a bare number, each city page returns YES, CAUTION or NO based on a weighted blend of pollen severity, air quality and weather such as wind speed.
Search by city name or ZIP code for locations in the United States, United Kingdom and Canada, covering regional pollen seasons that start and end at different times.
A continuously updated map shows current levels city by city, and a ranking surfaces the places with the highest pollen right now for trip planning.
A double opt-in subscription delivers one plain-text forecast each morning, so the check happens automatically before you open the windows or send kids outside.
