Tachiko Work

Semantic spreadsheets where AI proposes, Rust verifies.

0 followers

Tachiko Work is a semantic workspace for structured data where humans and AI operate on typed meaning instead of raw cells. For the GPT-6 Astra Challenge, Astra turns natural-language intent into typed proposals; Tachiko’s deterministic Rust engine validates formulas, dependencies, and impact before anything changes. Tachiko Sheet provides the familiar spreadsheet experience on top. Public pre-alpha.
