Session minimums are guaranteed floors, not averages, calculated from our own usage data to September 2026. A session means a topic deep-dive, a marked exam answer, or a diagram walkthrough. Most students comfortably exceed these figures.
Tokens are the units of text Otti processes — your questions, its responses, uploaded images, and essay feedback all use tokens. A typical back-and-forth revision session uses around 2,000–4,000 tokens, so even the Scholar plan comfortably covers multiple sessions every day.
