Co-Wryte — the notebook that writes back

Field notes

Co-Wryte describes a grid-paper browser canvas that accepts handwriting, mouse input, or typed questions, then returns AI explanations in the notebook. Its stated input range includes handwritten equations, physics setups, graphs, diagrams, code, and ordinary text. The license costs $20 once, activates on up to three devices, and covers future updates; model usage is billed separately through a user-supplied Anthropic, OpenAI, or Gemini key.
