Open Tools & Demos
Each tool encodes 40% of what a teacher does — the portion that's pattern-based and repeatable. The other 60% requires a human. One tool every three months. 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. Clone the repo, bring your own API key, run locally. Hosted demos: verify your email to try now — 10 free analyses, no account setup.
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.
Play Shape Diagnostic
Analyse experiential qualities of play concepts. Select three qualities from twelve — see whether your combination is harmonic, distinct, dynamic, complex, or paradoxical.
Coherence Diagnostic
Analyse design concepts for coherence. Shows what's strong, thin, or unclear across five dimensions. DeBERTa qualifies, deterministic rules judge, Haiku narrates.
