Chemistry has entered a high‑data regime as molecular databases from high‑throughput platforms and computational studies become increasingly abundant, driving a more digital and precision‑focused practice. The surge of both positive and negative results makes dedicated scientific agents essential for guiding chemists through the expanding knowledge space.
Magnolia is a persistent‑memory AI agent framework that unifies computational protocols—from docking to quantum chemistry—lab notebooks, and chat logs, leveraging large language models (LLMs) for natural‑language interaction and analysis.
The framework implements a three‑tier memory system: the session tier automatically captures observations and distills them into structured learnings; the project tier elevates confirmed learnings into project‑level entries; the cross‑project tier, once validated by humans, promotes these entries into rules that actively steer subsequent work and provide direct chemical feedback.
Four case studies illustrate Magnolia’s capabilities: quantum‑chemical evaluation of aromatic systems (COMPAS database), molecular dynamics of butane, dynamics of modified DNA, and a protein‑peptide docking campaign. Across these projects Magnolia tracked 317 runs, accumulated 116 project‑tier entries, and extracted four cross‑project rules. Controlled replays showed that runs with memory passed all checks (e.g., 10/10 docking‑configuration checks), whereas runs without memory succeeded in only 1‑4 of 10.
By combining automation, reproducibility, and human‑in‑the‑loop control, Magnolia streamlines docking, molecular dynamics, and quantum chemistry calculations, delivering direct analysis and LLM‑augmented feedback that accelerates access to computational (bio)chemistry.
