As answered by people managing JSONFormatter.org and Sessionplan.
Sessionplan's answer:
Sessionplan combines a visual, timeline-based planning experience with a strong commitment to simplicity and privacy. No account, no cloud, no cost — ever. Everything runs locally in your browser, making it fast, private, and accessible to anyone without any setup.
Sessionplan's answer:
Sessionplan is 100% free with no premium tiers or hidden costs. Unlike many competing tools, it requires no registration and stores no data in the cloud. It's lean, focused, and gets you from zero to a structured agenda in minutes.
Sessionplan's answer:
Trainers, coaches, facilitators, Scrum Masters, teachers, and event organizers — anyone who needs to plan a structured session and wants a simple, reliable tool without the overhead of complex software.
Sessionplan's answer:
Sessionplan was born out of a real frustration: existing tools were either too complex, too expensive, or both. As a professional facilitator, I needed something simple and reliable for my own work — so I built it myself. What started as a personal tool has since grown into a free resource for trainers, coaches, and facilitators around the world.
