Open Tools

Each tool encodes 40% of what a teacher does — the portion that's pattern-based and repeatable. The other 60% requires a human. Open source — the three existing tools (Coherence Diagnostic, Play Shape Diagnostic, Fragment Mapper) are under MIT; every new tool released after 5 April 2026 is under AGPL-3.0.

The list below sits in one frame: live web demos, sunsetted demos still on GitHub, and desktop downloads — each marked with its current state.

Fragment Mapper

See the structural relationships between scattered text fragments. Four signals measure meaning, vocabulary, emotion, and voice. Six deterministic rules surface neighbours, strays, rifts, forks, echoes, and shifts.
