Help build a better canvas for thinking with AI

PenEcho is an open-source spatial canvas where handwriting, equations, diagrams, and visual context become part of the conversation. It gives people a more natural way to explore ideas with AI beyond the chat box.

Your sponsorship helps fund:

  • reliable macOS, Windows, Linux, and mobile releases;
  • better canvas layout, performance, and pen interactions;
  • broader model and provider compatibility;
  • accessibility, localization, documentation, and examples;
  • testing, security work, issue triage, and long-term maintenance.

Individual sponsors help us keep improving the everyday experience. Company sponsors help sustain the engineering work behind a dependable, cross-platform open-source tool and can receive public recognition through the relevant sponsorship tier.

Sponsorship supports PenEcho's open-source development. It does not include a commercial license, service-level agreement, dedicated support, guaranteed feature delivery, or roadmap priority.
