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.

An AI work OS that finds your tasks and tells you what to do first
The proprietary PlansomScore algorithm ranks work by what needs attention now, weighing new requests and commitments against your existing goals and workload.
Connects to Gmail, Outlook, Slack, Notion, HubSpot and Granola to find tasks, commitments and decisions hidden in your communications and meetings.
Describe what you want to achieve and Plansom generates a structured plan with goals and the work needed to reach them, which you can edit and share.
Assign tasks to teammates with context attached, or activate built-in AI agents and track their activity and results from the same view.
