About
Crossary helps integration and migration teams turn source and target specification documents into reviewed, implementation-ready data-mapping workbooks. Upload both sides' specs — Excel, PDF, CSV, JSON, XML, XSD, SQL, or YAML and Crossary extracts a field inventory from each, then proposes a source-to-target mapping for every target field.
Every proposed row shows its work: the proposed source, the mapping type, the verbatim quote from your documents it is based on, the reasoning and assumptions behind it, and the AI's self-rated confidence — a triage cue, not a guarantee. When nothing fits, Crossary abstains instead of guessing: the row becomes an honest gap with a clarifying question, because a wrong mapping is worse than an honest gap.
You stay in control. Review, edit, accept, or reject each row, then run validation — a deterministic check of structure and key semantics (type compatibility, source-field references, cardinality); it is not a full correctness sign-off.

About
OpenSpec is an open-source spec-driven development framework designed to bring structure and clarity to AI-assisted coding workflows. It introduces a lightweight specification layer that helps teams define requirements before writing code. The platform organizes each change into structured artifacts such as proposals, specifications, designs, and task lists. It integrates with over 20 AI coding tools, allowing developers to use their preferred assistants while maintaining consistency. OpenSpec emphasizes an iterative and flexible approach rather than rigid development phases. Its command-based workflow enables users to propose, implement, and archive features efficiently. Overall, OpenSpec helps developers align with AI systems, reduce ambiguity, and produce more predictable and reliable outcomes.
