Tools

Five tools, one goal: make data easy to work with

Every tool runs in the open and follows the same public format specs.

Browse copy-ready, structured prompt templates for common AI tasks.

Generate cryptographic key pairs, seed phrases, and derived keys on demand.

Convert formats, extract properties, and generate thumbnails for social platforms.

Look up geographic data — address, timezone, elevation, and weather — from coordinates.

Generate UUIDs, Open Location Codes, and related test data, one at a time or in bulk.

See the format definitions behind every tool on the main project site.
