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.

Enterprise-grade neural machine translation, AI writing refinement, and real-time voice translation across thirty-plus global languages.
Translates whole PDF, Word (.docx), PowerPoint (.pptx), Excel (.xlsx), and HTML files up to 30 MB (Individual/Team) or 100 MB (Business/Enterprise) while keeping original fonts, tables, slides, and visual formatting intact.
Ensures consistent brand and technical terminology across language pairs using CSV-importable shared glossaries, automated glossary generation, shared style rule lists, and translation memory.
Enhances original drafts and translated copy with real-time sentence rewrites, word alternatives, and one-click tone adjustments (e.g., Business, Academic, Casual, Diplomatic) via browser, desktop, and Microsoft 365/Google Workspace add-ins.
Provides real-time spoken language translation and live multilingual captions for video conferences and mobile in-person dialogues, with 30 minutes per user per month included in paid DeepL Pro plans.
