Open-access research tools for exploring cultural knowledge systems. All tools are free to use and built on published data.
Interactive global map of ~5,300 endangered languages (Glottolog v5.3 AES, vulnerable through extinct) filtered by knowledge domain, endangerment level, and observability score. A triage tool for preservation efforts.
Open toolExplore 228,937 archaeological site records across 8 databases on a 3D globe. View the Great Circle corridor, migration routes, and settlement patterns.
Open toolInteractive agent-based simulation. Watch phase transitions emerge in real time as you adjust observability. Compare three models head-to-head.
Open toolRate a traditional knowledge claim on four observability dimensions. Get a predicted accuracy score calibrated against the 16-domain empirical dataset.
Open toolInput an oral tradition with geographic claims. The tool extracts testable predictions, pre-registers them, and identifies remote sensing datasets for validation.
Open toolInput ethnographic data from multiple cultures. Compute convergence indices, run permutation null models, and test whether convergence exceeds chance.
