A practical toolkit spanning sequence analysis, structure prediction, protein information lookup, and antibody risk assessment. No setup or coding required. Researchers can complete professional analyses through natural-language interaction and stay focused on the science.
Toolkit Overview
Design Philosophy
"In antibody R&D, many routine tasks, such as sequence numbering, physicochemical analysis, and structure retrieval, may look simple, but they often require multiple online tools or custom scripts. We turned these high-frequency workflows into conversational tools so researchers can complete them in natural language."
Explore 4 categories and 18+ tools covering everyday antibody R&D workflows. Every tool is available for free through conversational interaction.

Use Cases
Lightweight tools are designed for frequent, short-cycle auxiliary tasks in R&D, such as information lookup, sequence analysis, and structure analysis. Their value is rapid basic-information checks, visualization materials, and clearer inputs for downstream formal service projects.
